<p>When auto-white balance (AWB) is enabled with <a href="#controls_android.control.awbMode">android.<wbr/>control.<wbr/>awb<wbr/>Mode</a>,<wbr/> this
control is overridden by the AWB routine.<wbr/> When AWB is disabled,<wbr/> the
application controls how the color mapping is performed.<wbr/></p>
<p>We define the expected processing pipeline below.<wbr/> For consistency
across devices,<wbr/> this is always the case with TRANSFORM_<wbr/>MATRIX.<wbr/></p>
<p>When either FAST or HIGH_<wbr/>QUALITY is used,<wbr/> the camera device may
do additional processing but <a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> and
<a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> will still be provided by the
camera device (in the results) and be roughly correct.<wbr/></p>
<p>Switching to TRANSFORM_<wbr/>MATRIX and using the data provided from
FAST or HIGH_<wbr/>QUALITY will yield a picture with the same white point
as what was produced by the camera device in the earlier frame.<wbr/></p>
<p>The expected processing pipeline is as follows:</p>
<p><img alt="White balance processing pipeline" src="images/camera2/metadata/android.colorCorrection.mode/processing_pipeline.png"/></p>
<p>The white balance is encoded by two values,<wbr/> a 4-channel white-balance
gain vector (applied in the Bayer domain),<wbr/> and a 3x3 color transform
matrix (applied after demosaic).<wbr/></p>
<p>The 4-channel white-balance gains are defined as:</p>
<pre><code><a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> = [ R G_<wbr/>even G_<wbr/>odd B ]
</code></pre>
<p>where <code>G_<wbr/>even</code> is the gain for green pixels on even rows of the
output,<wbr/> and <code>G_<wbr/>odd</code> is the gain for green pixels on the odd rows.<wbr/>
These may be identical for a given camera device implementation; if
the camera device does not support a separate gain for even/<wbr/>odd green
channels,<wbr/> it will use the <code>G_<wbr/>even</code> value,<wbr/> and write <code>G_<wbr/>odd</code> equal to
<code>G_<wbr/>even</code> in the output result metadata.<wbr/></p>
<p>The matrices for color transforms are defined as a 9-entry vector:</p>
<pre><code><a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> = [ I0 I1 I2 I3 I4 I5 I6 I7 I8 ]
</code></pre>
<p>which define a transform from input sensor colors,<wbr/> <code>P_<wbr/>in = [ r g b ]</code>,<wbr/>
to output linear sRGB,<wbr/> <code>P_<wbr/>out = [ r' g' b' ]</code>,<wbr/></p>
<p>with colors as follows:</p>
<pre><code>r' = I0r + I1g + I2b
g' = I3r + I4g + I5b
b' = I6r + I7g + I8b
</code></pre>
<p>Both the input and output value ranges must match.<wbr/> Overflow/<wbr/>underflow

control is overridden by the AWB routine.<wbr/> When AWB is disabled,<wbr/> the
application controls how the color mapping is performed.<wbr/></p>
<p>We define the expected processing pipeline below.<wbr/> For consistency
across devices,<wbr/> this is always the case with TRANSFORM_<wbr/>MATRIX.<wbr/></p>
<p>When either FAST or HIGH_<wbr/>QUALITY is used,<wbr/> the camera device may
do additional processing but <a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> and
<a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> will still be provided by the
camera device (in the results) and be roughly correct.<wbr/></p>
<p>Switching to TRANSFORM_<wbr/>MATRIX and using the data provided from
FAST or HIGH_<wbr/>QUALITY will yield a picture with the same white point
as what was produced by the camera device in the earlier frame.<wbr/></p>
<p>The expected processing pipeline is as follows:</p>
<p><img alt="White balance processing pipeline" src="images/camera2/metadata/android.colorCorrection.mode/processing_pipeline.png"/></p>
<p>The white balance is encoded by two values,<wbr/> a 4-channel white-balance
gain vector (applied in the Bayer domain),<wbr/> and a 3x3 color transform
matrix (applied after demosaic).<wbr/></p>
<p>The 4-channel white-balance gains are defined as:</p>
<pre><code><a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> = [ R G_<wbr/>even G_<wbr/>odd B ]
</code></pre>
<p>where <code>G_<wbr/>even</code> is the gain for green pixels on even rows of the
output,<wbr/> and <code>G_<wbr/>odd</code> is the gain for green pixels on the odd rows.<wbr/>
These may be identical for a given camera device implementation; if
the camera device does not support a separate gain for even/<wbr/>odd green
channels,<wbr/> it will use the <code>G_<wbr/>even</code> value,<wbr/> and write <code>G_<wbr/>odd</code> equal to
<code>G_<wbr/>even</code> in the output result metadata.<wbr/></p>
<p>The matrices for color transforms are defined as a 9-entry vector:</p>
<pre><code><a href="#controls_android.colorCorrection.transform">android.<wbr/>color<wbr/>Correction.<wbr/>transform</a> = [ I0 I1 I2 I3 I4 I5 I6 I7 I8 ]
</code></pre>
<p>which define a transform from input sensor colors,<wbr/> <code>P_<wbr/>in = [ r g b ]</code>,<wbr/>
to output linear sRGB,<wbr/> <code>P_<wbr/>out = [ r' g' b' ]</code>,<wbr/></p>
<p>with colors as follows:</p>
<pre><code>r' = I0r + I1g + I2b
g' = I3r + I4g + I5b
b' = I6r + I7g + I8b
</code></pre>
<p>Both the input and output value ranges must match.<wbr/> Overflow/<wbr/>underflow

<p>When set to <code>true</code> (ON),<wbr/> the AE algorithm is locked to its latest parameters,<wbr/>
and will not change exposure settings until the lock is set to <code>false</code> (OFF).<wbr/></p>
<p>Note that even when AE is locked,<wbr/> the flash may be fired if
the <a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a> is ON_<wbr/>AUTO_<wbr/>FLASH /<wbr/>

<p>When <a href="#controls_android.control.aeExposureCompensation">android.<wbr/>control.<wbr/>ae<wbr/>Exposure<wbr/>Compensation</a> is changed,<wbr/> even if the AE lock

<p>If AE precapture is triggered (see <a href="#controls_android.control.aePrecaptureTrigger">android.<wbr/>control.<wbr/>ae<wbr/>Precapture<wbr/>Trigger</a>)
when AE is already locked,<wbr/> the camera device will not change the exposure time

<a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a> is ON_<wbr/>ALWAYS_<wbr/>FLASH,<wbr/> the scene may become overexposed.<wbr/>
Similarly,<wbr/> AE precapture trigger CANCEL has no effect when AE is already locked.<wbr/></p>
<p>When an AE precapture sequence is triggered,<wbr/> AE unlock will not be able to unlock
the AE if AE is locked by the camera device internally during precapture metering
sequence In other words,<wbr/> submitting requests with AE unlock has no effect for an
ongoing precapture metering sequence.<wbr/> Otherwise,<wbr/> the precapture metering sequence
will never succeed in a sequence of preview requests where AE lock is always set
to <code>false</code>.<wbr/></p>
<p>Since the camera device has a pipeline of in-flight requests,<wbr/> the settings that
get locked do not necessarily correspond to the settings that were present in the
latest capture result received from the camera device,<wbr/> since additional captures
and AE updates may have occurred even before the result was sent out.<wbr/> If an
application is switching between automatic and manual control and wishes to eliminate
any flicker during the switch,<wbr/> the following procedure is recommended:</p>
<ol>
<li>Starting in auto-AE mode:</li>
<li>Lock AE</li>
<li>Wait for the first result to be output that has the AE locked</li>
<li>Copy exposure settings from that result into a request,<wbr/> set the request to manual AE</li>
<li>Submit the capture request,<wbr/> proceed to run manual AE as desired.<wbr/></li>

<p>The weight must be within <code>[0,<wbr/> 1000]</code>,<wbr/> and represents a weight
for every pixel in the area.<wbr/> This means that a large metering area
with the same weight as a smaller area will have more effect in
the metering result.<wbr/> Metering areas can partially overlap and the
camera device will add the weights in the overlap region.<wbr/></p>
<p>The weights are relative to weights of other exposure metering regions,<wbr/> so if only one
region is used,<wbr/> all non-zero weights will have the same effect.<wbr/> A region with 0
weight is ignored.<wbr/></p>
<p>If all regions have 0 weight,<wbr/> then no specific metering area needs to be used by the
camera device.<wbr/></p>
<p>If the metering region is outside the used <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> returned in
capture result metadata,<wbr/> the camera device will ignore the sections outside the crop
region and output only the intersection rectangle as the metering region in the result
metadata.<wbr/> If the region is entirely outside the crop region,<wbr/> it will be ignored and
not reported in the result metadata.<wbr/></p>
<p>When setting the AE metering regions,<wbr/> the application must consider the additional
crop resulted from the aspect ratio differences between the preview stream and
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>.<wbr/> For example,<wbr/> if the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> is the full
active array size with 4:3 aspect ratio,<wbr/> and the preview stream is 16:9,<wbr/>
the boundary of AE regions will be [0,<wbr/> y_<wbr/>crop] and
[active_<wbr/>width,<wbr/> active_<wbr/>height - 2 * y_<wbr/>crop] rather than [0,<wbr/> 0] and
[active_<wbr/>width,<wbr/> active_<wbr/>height],<wbr/> where y_<wbr/>crop is the additional crop due to aspect ratio
mismatch.<wbr/></p>
<p>Starting from API level 30,<wbr/> the coordinate system of activeArraySize or
preCorrectionActiveArraySize is used to represent post-zoomRatio field of view,<wbr/> not
pre-zoom field of view.<wbr/> This means that the same aeRegions values at different
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> represent different parts of the scene.<wbr/> The aeRegions
coordinates are relative to the activeArray/<wbr/>preCorrectionActiveArray representing the
zoomed field of view.<wbr/> If <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is set to 1.<wbr/>0 (default),<wbr/> the same
aeRegions at different <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> still represent the same parts of the
scene as they do before.<wbr/> See <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> for details.<wbr/> Whether to use
activeArraySize or preCorrectionActiveArraySize still depends on distortion correction
mode.<wbr/></p>

If a precapture metering sequence is already completed,<wbr/> and the camera

CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
<p>The precapture sequence should be triggered before starting a
high-quality still capture for final metering decisions to
be made,<wbr/> and for firing pre-capture flash pulses to estimate
scene brightness and required final capture flash power,<wbr/> when
the flash is enabled.<wbr/></p>
<p>Normally,<wbr/> this entry should be set to START for only a
single request,<wbr/> and the application should wait until the

<p>When a precapture metering sequence is finished,<wbr/> the camera device
may lock the auto-exposure routine internally to be able to accurately expose the
subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is

submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
internally locked AE if the application doesn't submit a still capture request after
the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
be used in devices that have earlier API levels.<wbr/></p>
<p>The exact effect of auto-exposure (AE) precapture trigger
depends on the current AE mode and state; see
<a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> for AE precapture state transition
details.<wbr/></p>
<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
capturing a high-resolution JPEG image will automatically trigger a
precapture sequence before the high-resolution capture,<wbr/> including
potentially firing a pre-capture flash.<wbr/></p>
<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for
example.<wbr/></p>
<p>If both the precapture and the auto-focus trigger are activated on the same request,<wbr/> then
the camera device will complete them in the optimal order for that device.<wbr/></p>

<p>The weight must be within <code>[0,<wbr/> 1000]</code>,<wbr/> and represents a weight

with the same weight as a smaller area will have more effect in
the metering result.<wbr/> Metering areas can partially overlap and the

ignored.<wbr/></p>
<p>If all regions have 0 weight,<wbr/> then no specific metering area needs to be used by the

not reported in the result metadata.<wbr/></p>
<p>When setting the AF metering regions,<wbr/> the application must consider the additional

[active_<wbr/>width,<wbr/> active_<wbr/>height - 2 * y_<wbr/>crop] rather than [0,<wbr/> 0] and
[active_<wbr/>width,<wbr/> active_<wbr/>height],<wbr/> where y_<wbr/>crop is the additional crop due to aspect ratio
mismatch.<wbr/></p>
<p>Starting from API level 30,<wbr/> the coordinate system of activeArraySize or
preCorrectionActiveArraySize is used to represent post-zoomRatio field of view,<wbr/> not
pre-zoom field of view.<wbr/> This means that the same afRegions values at different
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> represent different parts of the scene.<wbr/> The afRegions
coordinates are relative to the activeArray/<wbr/>preCorrectionActiveArray representing the
zoomed field of view.<wbr/> If <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is set to 1.<wbr/>0 (default),<wbr/> the same
afRegions at different <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> still represent the same parts of the

<p>Since the camera device has a pipeline of in-flight requests,<wbr/> the settings that

<p>For devices supporting <a href="#controls_android.distortionCorrection.mode">android.<wbr/>distortion<wbr/>Correction.<wbr/>mode</a> control,<wbr/> the coordinate

<p>The weight must range from 0 to 1000,<wbr/> and represents a weight
for every pixel in the area.<wbr/> This means that a large metering area
with the same weight as a smaller area will have more effect in
the metering result.<wbr/> Metering areas can partially overlap and the
camera device will add the weights in the overlap region.<wbr/></p>
<p>The weights are relative to weights of other white balance metering regions,<wbr/> so if
only one region is used,<wbr/> all non-zero weights will have the same effect.<wbr/> A region with
0 weight is ignored.<wbr/></p>
<p>If all regions have 0 weight,<wbr/> then no specific metering area needs to be used by the
camera device.<wbr/></p>
<p>If the metering region is outside the used <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> returned in
capture result metadata,<wbr/> the camera device will ignore the sections outside the crop
region and output only the intersection rectangle as the metering region in the result
metadata.<wbr/> If the region is entirely outside the crop region,<wbr/> it will be ignored and
not reported in the result metadata.<wbr/></p>
<p>When setting the AWB metering regions,<wbr/> the application must consider the additional
crop resulted from the aspect ratio differences between the preview stream and
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>.<wbr/> For example,<wbr/> if the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> is the full
active array size with 4:3 aspect ratio,<wbr/> and the preview stream is 16:9,<wbr/>
the boundary of AWB regions will be [0,<wbr/> y_<wbr/>crop] and
[active_<wbr/>width,<wbr/> active_<wbr/>height - 2 * y_<wbr/>crop] rather than [0,<wbr/> 0] and
[active_<wbr/>width,<wbr/> active_<wbr/>height],<wbr/> where y_<wbr/>crop is the additional crop due to aspect ratio
mismatch.<wbr/></p>
<p>Starting from API level 30,<wbr/> the coordinate system of activeArraySize or
preCorrectionActiveArraySize is used to represent post-zoomRatio field of view,<wbr/> not
pre-zoom field of view.<wbr/> This means that the same awbRegions values at different
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> represent different parts of the scene.<wbr/> The awbRegions
coordinates are relative to the activeArray/<wbr/>preCorrectionActiveArray representing the
zoomed field of view.<wbr/> If <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is set to 1.<wbr/>0 (default),<wbr/> the same
awbRegions at different <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> still represent the same parts of
the scene as they do before.<wbr/> See <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> for details.<wbr/> Whether to use
activeArraySize or preCorrectionActiveArraySize still depends on distortion correction
mode.<wbr/></p>

the application need check if the video encoder is capable of supporting the
high frame rate for a given video size,<wbr/> or it will end up with lower recording
frame rate.<wbr/> If the destination surface is from preview window,<wbr/> the preview frame
rate will be bounded by the screen refresh rate.<wbr/></p>
<p>The camera device will only support up to 2 output high speed streams

<span class="entry_type_enum_optional">[optional]</span>
<span class="entry_type_enum_notes"><p>Turn on a device-specific high dynamic range (HDR) mode.<wbr/></p>
<p>In this scene mode,<wbr/> the camera device captures images
that keep a larger range of scene illumination levels
visible in the final image.<wbr/> For example,<wbr/> when taking a
picture of a object in front of a bright window,<wbr/> both
the object and the scene through the window may be
visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
HDR mode generally takes much longer to capture a single
image,<wbr/> has no user control,<wbr/> and may have other artifacts
depending on the HDR method used.<wbr/></p>
<p>Therefore,<wbr/> HDR captures operate at a much slower rate
than regular captures.<wbr/></p>
<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
using a high dynamic range capture technique.<wbr/> On LEGACY
devices,<wbr/> captures that target a JPEG-format output will
be captured with HDR,<wbr/> and the capture intent is not
relevant.<wbr/></p>
<p>The HDR capture may involve the device capturing a burst
of images internally and combining them into one,<wbr/> or it
may involve the device using specialized high dynamic
range capture hardware.<wbr/> In all cases,<wbr/> a single image is
produced in response to a capture request submitted

<p>Since substantial post-processing is generally needed to
produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
outputs are supported for LIMITED/<wbr/>FULL device HDR
captures,<wbr/> and only JPEG outputs are supported for LEGACY
HDR captures.<wbr/> Using a RAW output for HDR capture is not
supported.<wbr/></p>
<p>Some devices may also support always-on HDR,<wbr/> which
applies HDR processing at full frame rate.<wbr/> For these
devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
produce an HDR output with no frame rate impact compared
to normal operation,<wbr/> though the quality may be lower
than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types
or capture intents,<wbr/> the images captured will be as if
the SCENE_<wbr/>MODE was not enabled at all.<wbr/></p></span>

device will choose higher sensitivity values (<a href="#controls_android.sensor.sensitivity">android.<wbr/>sensor.<wbr/>sensitivity</a>)
under low light conditions.<wbr/></p>
<p>The camera device may be tuned to expose the images in a reduced
sensitivity range to produce the best quality images.<wbr/> For example,<wbr/>
if the <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> gives range of [100,<wbr/> 1600],<wbr/>
the camera device auto-exposure routine tuning process may limit the actual
exposure sensitivity range to [100,<wbr/> 1200] to ensure that the noise level isn't
excessive in order to preserve the image quality.<wbr/> Under this situation,<wbr/> the image under
low light may be under-exposed when the sensor max exposure time (bounded by the
<a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a> when <a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a> is one of the
ON_<wbr/>* modes) and effective max sensitivity are reached.<wbr/> This scene mode allows the
camera device auto-exposure routine to increase the sensitivity up to the max
sensitivity specified by <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> when the scene is too
dark and the max exposure time is reached.<wbr/> The captured images may be noisier
compared with the images captured in normal FACE_<wbr/>PRIORITY mode; therefore,<wbr/> it is
recommended that the application only use this scene mode when it is capable of
reducing the noise level of the captured images.<wbr/></p>

use this tag to specify the desired zoom level.<wbr/></p>
<p>By using this control,<wbr/> the application gains a simpler way to control zoom,<wbr/> which can
be a combination of optical and digital zoom.<wbr/> For example,<wbr/> a multi-camera system may
contain more than one lens with different focal lengths,<wbr/> and the user can use optical
zoom by switching between lenses.<wbr/> Using zoomRatio has benefits in the scenarios below:</p>
<ul>
<li>Zooming in from a wide-angle lens to a telephoto lens: A floating-point ratio provides
better precision compared to an integer value of <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>.<wbr/></li>
<li>Zooming out from a wide lens to an ultrawide lens: zoomRatio supports zoom-out whereas
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> doesn't.<wbr/></li>
</ul>
<p>To illustrate,<wbr/> here are several scenarios of different zoom ratios,<wbr/> crop regions,<wbr/>
and output streams,<wbr/> for a hypothetical camera device with an active array of size
<code>(2000,<wbr/>1500)</code>.<wbr/></p>
<ul>
<li>Camera Configuration:<ul>
<li>Active array size: <code>2000x1500</code> (3 MP,<wbr/> 4:3 aspect ratio)</li>
<li>Output stream #1: <code>640x480</code> (VGA,<wbr/> 4:3 aspect ratio)</li>
<li>Output stream #2: <code>1280x720</code> (720p,<wbr/> 16:9 aspect ratio)</li>
</ul>
</li>
<li>Case #1: 4:3 crop region with 2.<wbr/>0x zoom ratio<ul>
<li>Zoomed field of view: 1/<wbr/>4 of original field of view</li>
<li>Crop region: <code>Rect(0,<wbr/> 0,<wbr/> 2000,<wbr/> 1500) //<wbr/> (left,<wbr/> top,<wbr/> right,<wbr/> bottom)</code> (post zoom)</li>
</ul>
</li>
<li><img alt="4:3 aspect ratio crop diagram" src="images/camera2/metadata/android.control.zoomRatio/zoom-ratio-2-crop-43.png"/><ul>
<li><code>640x480</code> stream source area: <code>(0,<wbr/> 0,<wbr/> 2000,<wbr/> 1500)</code> (equal to crop region)</li>
<li><code>1280x720</code> stream source area: <code>(0,<wbr/> 187,<wbr/> 2000,<wbr/> 1312)</code> (letterboxed)</li>
</ul>
</li>
<li>Case #2: 16:9 crop region with 2.<wbr/>0x zoom.<wbr/><ul>
<li>Zoomed field of view: 1/<wbr/>4 of original field of view</li>
<li>Crop region: <code>Rect(0,<wbr/> 187,<wbr/> 2000,<wbr/> 1312)</code></li>
<li><img alt="16:9 aspect ratio crop diagram" src="images/camera2/metadata/android.control.zoomRatio/zoom-ratio-2-crop-169.png"/></li>
<li><code>640x480</code> stream source area: <code>(250,<wbr/> 187,<wbr/> 1750,<wbr/> 1312)</code> (pillarboxed)</li>
<li><code>1280x720</code> stream source area: <code>(0,<wbr/> 187,<wbr/> 2000,<wbr/> 1312)</code> (equal to crop region)</li>
</ul>
</li>
<li>Case #3: 1:1 crop region with 0.<wbr/>5x zoom out to ultrawide lens.<wbr/><ul>
<li>Zoomed field of view: 4x of original field of view (switched from wide lens to ultrawide lens)</li>
<li>Crop region: <code>Rect(250,<wbr/> 0,<wbr/> 1750,<wbr/> 1500)</code></li>
<li><img alt="1:1 aspect ratio crop diagram" src="images/camera2/metadata/android.control.zoomRatio/zoom-ratio-0.5-crop-11.png"/></li>
<li><code>640x480</code> stream source area: <code>(250,<wbr/> 187,<wbr/> 1750,<wbr/> 1312)</code> (letterboxed)</li>
<li><code>1280x720</code> stream source area: <code>(250,<wbr/> 328,<wbr/> 1750,<wbr/> 1172)</code> (letterboxed)</li>
</ul>
</li>
</ul>
<p>As seen from the graphs above,<wbr/> the coordinate system of cropRegion now changes to the
effective after-zoom field-of-view,<wbr/> and is represented by the rectangle of (0,<wbr/> 0,<wbr/>
activeArrayWith,<wbr/> activeArrayHeight).<wbr/> The same applies to AE/<wbr/>AWB/<wbr/>AF regions,<wbr/> and faces.<wbr/>
This coordinate system change isn't applicable to RAW capture and its related
metadata such as intrinsicCalibration and lensShadingMap.<wbr/></p>
<p>Using the same hypothetical example above,<wbr/> and assuming output stream #1 (640x480) is
the viewfinder stream,<wbr/> the application can achieve 2.<wbr/>0x zoom in one of two ways:</p>
<ul>
<li>zoomRatio = 2.<wbr/>0,<wbr/> scaler.<wbr/>cropRegion = (0,<wbr/> 0,<wbr/> 2000,<wbr/> 1500)</li>
<li>zoomRatio = 1.<wbr/>0 (default),<wbr/> scaler.<wbr/>cropRegion = (500,<wbr/> 375,<wbr/> 1500,<wbr/> 1125)</li>
</ul>
<p>If the application intends to set aeRegions to be top-left quarter of the viewfinder
field-of-view,<wbr/> the <a href="#controls_android.control.aeRegions">android.<wbr/>control.<wbr/>ae<wbr/>Regions</a> should be set to (0,<wbr/> 0,<wbr/> 1000,<wbr/> 750) with
zoomRatio set to 2.<wbr/>0.<wbr/> Alternatively,<wbr/> the application can set aeRegions to the equivalent
region of (500,<wbr/> 375,<wbr/> 1000,<wbr/> 750) for zoomRatio of 1.<wbr/>0.<wbr/> If the application doesn't
explicitly set <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a>,<wbr/> its value defaults to 1.<wbr/>0.<wbr/></p>
<p>One limitation of controlling zoom using zoomRatio is that the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>
must only be used for letterboxing or pillarboxing of the sensor active array,<wbr/> and no
FREEFORM cropping can be used with <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> other than 1.<wbr/>0.<wbr/> If
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is not 1.<wbr/>0,<wbr/> and <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> is set to be
windowboxing,<wbr/> the camera framework will override the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> to be
the active array.<wbr/></p>
<p>In the capture request,<wbr/> if the application sets <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> to a
value != 1.<wbr/>0,<wbr/> the <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> tag in the capture result reflects the
effective zoom ratio achieved by the camera device,<wbr/> and the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>
adjusts for additional crops that are not zoom related.<wbr/> Otherwise,<wbr/> if the application
sets <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> to 1.<wbr/>0,<wbr/> or does not set it at all,<wbr/> the
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> tag in the result metadata will also be 1.<wbr/>0.<wbr/></p>
<p>When the application requests a physical stream for a logical multi-camera,<wbr/> the
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> in the physical camera result metadata will be 1.<wbr/>0,<wbr/> and
the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> tag reflects the amount of zoom and crop done by the
physical camera device.<wbr/></p>

<p>When CONSTRAINED_<wbr/>HIGH_<wbr/>SPEED_<wbr/>VIDEO is supported in <a href="#static_android.request.availableCapabilities">android.<wbr/>request.<wbr/>available<wbr/>Capabilities</a>,<wbr/>
this metadata will list the supported high speed video size,<wbr/> fps range and max batch size
configurations.<wbr/> All the sizes listed in this configuration will be a subset of the sizes
reported by <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputSizes">StreamConfigurationMap#getOutputSizes</a>
for processed non-stalling formats.<wbr/></p>
<p>For the high speed video use case,<wbr/> the application must
select the video size and fps range from this metadata to configure the recording and
preview streams and setup the recording requests.<wbr/> For example,<wbr/> if the application intends
to do high speed recording,<wbr/> it can select the maximum size reported by this metadata to
configure output streams.<wbr/> Once the size is selected,<wbr/> application can filter this metadata
by selected size and get the supported fps ranges,<wbr/> and use these fps ranges to setup the
recording requests.<wbr/> Note that for the use case of multiple output streams,<wbr/> application
must select one unique size from this metadata to use (e.<wbr/>g.,<wbr/> preview and recording streams
must have the same size).<wbr/> Otherwise,<wbr/> the high speed capture session creation will fail.<wbr/></p>
<p>The min and max fps will be multiple times of 30fps.<wbr/></p>
<p>High speed video streaming extends significant performance pressure to camera hardware,<wbr/>
to achieve efficient high speed streaming,<wbr/> the camera device may have to aggregate
multiple frames together and send to camera device for processing where the request
controls are same for all the frames in this batch.<wbr/> Max batch size indicates
the max possible number of frames the camera device will group together for this high
speed stream configuration.<wbr/> This max batch size will be used to generate a high speed
recording request list by
<a href="https://developer.android.com/reference/android/hardware/camera2/CameraConstrainedHighSpeedCaptureSession.html#createHighSpeedRequestList">CameraConstrainedHighSpeedCaptureSession#createHighSpeedRequestList</a>.<wbr/>
The max batch size for each configuration will satisfy below conditions:</p>
<ul>
<li>Each max batch size will be a divisor of its corresponding fps_<wbr/>max /<wbr/> 30.<wbr/> For example,<wbr/>
if max_<wbr/>fps is 300,<wbr/> max batch size will only be 1,<wbr/> 2,<wbr/> 5,<wbr/> or 10.<wbr/></li>
<li>The camera device may choose smaller internal batch size for each configuration,<wbr/> but
the actual batch size will be a divisor of max batch size.<wbr/> For example,<wbr/> if the max batch
size is 8,<wbr/> the actual batch size used by camera device will only be 1,<wbr/> 2,<wbr/> 4,<wbr/> or 8.<wbr/></li>
<li>The max batch size in each configuration entry must be no larger than 32.<wbr/></li>
</ul>
<p>The camera device doesn't have to support batch mode to achieve high speed video recording,<wbr/>
in such case,<wbr/> batch_<wbr/>size_<wbr/>max will be reported as 1 in each configuration entry.<wbr/></p>
<p>This fps ranges in this configuration list can only be used to create requests
that are submitted to a high speed camera capture session created by
<a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createConstrainedHighSpeedCaptureSession">CameraDevice#createConstrainedHighSpeedCaptureSession</a>.<wbr/>
The fps ranges reported in this metadata must not be used to setup capture requests for
normal capture session,<wbr/> or it will cause request error.<wbr/></p>

<a href="#static_android.scaler.availableStreamConfigurations">android.<wbr/>scaler.<wbr/>available<wbr/>Stream<wbr/>Configurations</a> for processed non-stalling output formats.<wbr/>
Note that for all high speed video configurations,<wbr/> HAL must be able to support a minimum
of two streams,<wbr/> though the application might choose to configure just one stream.<wbr/></p>
<p>The HAL may support multiple sensor modes for high speed outputs,<wbr/> for example,<wbr/> 120fps
sensor mode and 120fps recording,<wbr/> 240fps sensor mode for 240fps recording.<wbr/> The application
usually starts preview first,<wbr/> then starts recording.<wbr/> To avoid sensor mode switch caused
stutter when starting recording as much as possible,<wbr/> the application may want to ensure
the same sensor mode is used for preview and recording.<wbr/> Therefore,<wbr/> The HAL must advertise
the variable fps range [30,<wbr/> fps_<wbr/>max] for each fixed fps range in this configuration list.<wbr/>
For example,<wbr/> if the HAL advertises [120,<wbr/> 120] and [240,<wbr/> 240],<wbr/> the HAL must also advertise
[30,<wbr/> 120] and [30,<wbr/> 240] for each configuration.<wbr/> In doing so,<wbr/> if the application intends to
do 120fps recording,<wbr/> it can select [30,<wbr/> 120] to start preview,<wbr/> and [120,<wbr/> 120] to start
recording.<wbr/> For these variable fps ranges,<wbr/> it's up to the HAL to decide the actual fps
values that are suitable for smooth preview streaming.<wbr/>
If the HAL sees different max_<wbr/>fps values that fall into different sensor modes in a
sequence of requests,<wbr/> the HAL must switch the sensor mode as quick as possible to minimize
the mode switch caused stutter.<wbr/></p>
<p>HAL can also support 60fps preview during high speed recording session by advertising
[60,<wbr/> max_<wbr/>fps] for preview and [max_<wbr/>fps,<wbr/> max_<wbr/>fps] for recording.<wbr/> However,<wbr/> HAL must not
advertise both 30fps preview and 60fps preview for the same recording frame rate.<wbr/></p>

Similarly,<wbr/> AE precapture trigger CANCEL has no effect when AE is already locked.<wbr/></p>
<p>When an AE precapture sequence is triggered,<wbr/> AE unlock will not be able to unlock
the AE if AE is locked by the camera device internally during precapture metering
sequence In other words,<wbr/> submitting requests with AE unlock has no effect for an
ongoing precapture metering sequence.<wbr/> Otherwise,<wbr/> the precapture metering sequence
will never succeed in a sequence of preview requests where AE lock is always set
to <code>false</code>.<wbr/></p>
<p>Since the camera device has a pipeline of in-flight requests,<wbr/> the settings that
get locked do not necessarily correspond to the settings that were present in the
latest capture result received from the camera device,<wbr/> since additional captures
and AE updates may have occurred even before the result was sent out.<wbr/> If an
application is switching between automatic and manual control and wishes to eliminate
any flicker during the switch,<wbr/> the following procedure is recommended:</p>
<ol>
<li>Starting in auto-AE mode:</li>
<li>Lock AE</li>
<li>Wait for the first result to be output that has the AE locked</li>
<li>Copy exposure settings from that result into a request,<wbr/> set the request to manual AE</li>
<li>Submit the capture request,<wbr/> proceed to run manual AE as desired.<wbr/></li>

<p>For devices supporting <a href="#controls_android.distortionCorrection.mode">android.<wbr/>distortion<wbr/>Correction.<wbr/>mode</a> control,<wbr/> the coordinate

<p>The weight must be within <code>[0,<wbr/> 1000]</code>,<wbr/> and represents a weight
for every pixel in the area.<wbr/> This means that a large metering area
with the same weight as a smaller area will have more effect in
the metering result.<wbr/> Metering areas can partially overlap and the
camera device will add the weights in the overlap region.<wbr/></p>
<p>The weights are relative to weights of other exposure metering regions,<wbr/> so if only one
region is used,<wbr/> all non-zero weights will have the same effect.<wbr/> A region with 0
weight is ignored.<wbr/></p>
<p>If all regions have 0 weight,<wbr/> then no specific metering area needs to be used by the
camera device.<wbr/></p>
<p>If the metering region is outside the used <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> returned in
capture result metadata,<wbr/> the camera device will ignore the sections outside the crop
region and output only the intersection rectangle as the metering region in the result
metadata.<wbr/> If the region is entirely outside the crop region,<wbr/> it will be ignored and
not reported in the result metadata.<wbr/></p>
<p>When setting the AE metering regions,<wbr/> the application must consider the additional
crop resulted from the aspect ratio differences between the preview stream and
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>.<wbr/> For example,<wbr/> if the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> is the full
active array size with 4:3 aspect ratio,<wbr/> and the preview stream is 16:9,<wbr/>
the boundary of AE regions will be [0,<wbr/> y_<wbr/>crop] and
[active_<wbr/>width,<wbr/> active_<wbr/>height - 2 * y_<wbr/>crop] rather than [0,<wbr/> 0] and
[active_<wbr/>width,<wbr/> active_<wbr/>height],<wbr/> where y_<wbr/>crop is the additional crop due to aspect ratio
mismatch.<wbr/></p>
<p>Starting from API level 30,<wbr/> the coordinate system of activeArraySize or
preCorrectionActiveArraySize is used to represent post-zoomRatio field of view,<wbr/> not
pre-zoom field of view.<wbr/> This means that the same aeRegions values at different
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> represent different parts of the scene.<wbr/> The aeRegions
coordinates are relative to the activeArray/<wbr/>preCorrectionActiveArray representing the
zoomed field of view.<wbr/> If <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is set to 1.<wbr/>0 (default),<wbr/> the same
aeRegions at different <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> still represent the same parts of the
scene as they do before.<wbr/> See <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> for details.<wbr/> Whether to use
activeArraySize or preCorrectionActiveArraySize still depends on distortion correction
mode.<wbr/></p>

<p>This entry is normally set to IDLE,<wbr/> or is not
included at all in the request settings.<wbr/> When included and
set to START,<wbr/> the camera device will trigger the auto-exposure (AE)
precapture metering sequence.<wbr/></p>
<p>When set to CANCEL,<wbr/> the camera device will cancel any active
precapture metering trigger,<wbr/> and return to its initial AE state.<wbr/>
If a precapture metering sequence is already completed,<wbr/> and the camera
device has implicitly locked the AE for subsequent still capture,<wbr/> the
CANCEL trigger will unlock the AE and return to its initial AE state.<wbr/></p>
<p>The precapture sequence should be triggered before starting a
high-quality still capture for final metering decisions to
be made,<wbr/> and for firing pre-capture flash pulses to estimate
scene brightness and required final capture flash power,<wbr/> when
the flash is enabled.<wbr/></p>
<p>Normally,<wbr/> this entry should be set to START for only a
single request,<wbr/> and the application should wait until the
sequence completes before starting a new one.<wbr/></p>
<p>When a precapture metering sequence is finished,<wbr/> the camera device
may lock the auto-exposure routine internally to be able to accurately expose the
subsequent still capture image (<code><a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> == STILL_<wbr/>CAPTURE</code>).<wbr/>
For this case,<wbr/> the AE may not resume normal scan if no subsequent still capture is
submitted.<wbr/> To ensure that the AE routine restarts normal scan,<wbr/> the application should
submit a request with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == true</code>,<wbr/> followed by a request
with <code><a href="#controls_android.control.aeLock">android.<wbr/>control.<wbr/>ae<wbr/>Lock</a> == false</code>,<wbr/> if the application decides not to submit a
still capture request after the precapture sequence completes.<wbr/> Alternatively,<wbr/> for
API level 23 or newer devices,<wbr/> the CANCEL can be used to unlock the camera device
internally locked AE if the application doesn't submit a still capture request after
the AE precapture trigger.<wbr/> Note that,<wbr/> the CANCEL was added in API level 23,<wbr/> and must not
be used in devices that have earlier API levels.<wbr/></p>
<p>The exact effect of auto-exposure (AE) precapture trigger
depends on the current AE mode and state; see
<a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> for AE precapture state transition
details.<wbr/></p>
<p>On LEGACY-level devices,<wbr/> the precapture trigger is not supported;
capturing a high-resolution JPEG image will automatically trigger a
precapture sequence before the high-resolution capture,<wbr/> including
potentially firing a pre-capture flash.<wbr/></p>
<p>Using the precapture trigger and the auto-focus trigger <a href="#controls_android.control.afTrigger">android.<wbr/>control.<wbr/>af<wbr/>Trigger</a>
simultaneously is allowed.<wbr/> However,<wbr/> since these triggers often require cooperation between
the auto-focus and auto-exposure routines (for example,<wbr/> the may need to be enabled for a
focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
changes to <a href="#dynamic_android.control.aeState">android.<wbr/>control.<wbr/>ae<wbr/>State</a> indicating the start of the precapture sequence,<wbr/> for
example.<wbr/></p>
<p>If both the precapture and the auto-focus trigger are activated on the same request,<wbr/> then
the camera device will complete them in the optimal order for that device.<wbr/></p>

<p>When afMode is one of the continuous auto focus modes,<wbr/> the HAL is free to start a AF

<p>To put this in concrete terms,<wbr/> if the camera has lens elements which may move based on

remain in a fixed position invariant to the camera's orientation or motion,<wbr/> for example,<wbr/>
by using accelerometer measurements in the lens control logic.<wbr/> This is a typical issue

<p>The weight must be within <code>[0,<wbr/> 1000]</code>,<wbr/> and represents a weight
for every pixel in the area.<wbr/> This means that a large metering area
with the same weight as a smaller area will have more effect in
the metering result.<wbr/> Metering areas can partially overlap and the
camera device will add the weights in the overlap region.<wbr/></p>
<p>The weights are relative to weights of other metering regions,<wbr/> so if only one region
is used,<wbr/> all non-zero weights will have the same effect.<wbr/> A region with 0 weight is
ignored.<wbr/></p>
<p>If all regions have 0 weight,<wbr/> then no specific metering area needs to be used by the
camera device.<wbr/> The capture result will either be a zero weight region as well,<wbr/> or
the region selected by the camera device as the focus area of interest.<wbr/></p>
<p>If the metering region is outside the used <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> returned in

region and output only the intersection rectangle as the metering region in the result
metadata.<wbr/> If the region is entirely outside the crop region,<wbr/> it will be ignored and
not reported in the result metadata.<wbr/></p>
<p>When setting the AF metering regions,<wbr/> the application must consider the additional
crop resulted from the aspect ratio differences between the preview stream and
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>.<wbr/> For example,<wbr/> if the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> is the full
active array size with 4:3 aspect ratio,<wbr/> and the preview stream is 16:9,<wbr/>
the boundary of AF regions will be [0,<wbr/> y_<wbr/>crop] and
[active_<wbr/>width,<wbr/> active_<wbr/>height - 2 * y_<wbr/>crop] rather than [0,<wbr/> 0] and
[active_<wbr/>width,<wbr/> active_<wbr/>height],<wbr/> where y_<wbr/>crop is the additional crop due to aspect ratio
mismatch.<wbr/></p>
<p>Starting from API level 30,<wbr/> the coordinate system of activeArraySize or
preCorrectionActiveArraySize is used to represent post-zoomRatio field of view,<wbr/> not
pre-zoom field of view.<wbr/> This means that the same afRegions values at different
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> represent different parts of the scene.<wbr/> The afRegions
coordinates are relative to the activeArray/<wbr/>preCorrectionActiveArray representing the
zoomed field of view.<wbr/> If <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is set to 1.<wbr/>0 (default),<wbr/> the same
afRegions at different <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> still represent the same parts of the
scene as they do before.<wbr/> See <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> for details.<wbr/> Whether to use
activeArraySize or preCorrectionActiveArraySize still depends on distortion correction

focus sweep),<wbr/> the camera device may delay acting on a later trigger until the previous
trigger has been fully handled.<wbr/> This may lead to longer intervals between the trigger and
changes to <a href="#dynamic_android.control.afState">android.<wbr/>control.<wbr/>af<wbr/>State</a>,<wbr/> for example.<wbr/></p>

<p>For devices supporting <a href="#controls_android.distortionCorrection.mode">android.<wbr/>distortion<wbr/>Correction.<wbr/>mode</a> control,<wbr/> the coordinate

When the distortion correction mode is not OFF,<wbr/> the coordinate system follows

<p>The weight must range from 0 to 1000,<wbr/> and represents a weight
for every pixel in the area.<wbr/> This means that a large metering area
with the same weight as a smaller area will have more effect in
the metering result.<wbr/> Metering areas can partially overlap and the
camera device will add the weights in the overlap region.<wbr/></p>
<p>The weights are relative to weights of other white balance metering regions,<wbr/> so if
only one region is used,<wbr/> all non-zero weights will have the same effect.<wbr/> A region with
0 weight is ignored.<wbr/></p>
<p>If all regions have 0 weight,<wbr/> then no specific metering area needs to be used by the
camera device.<wbr/></p>
<p>If the metering region is outside the used <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> returned in
capture result metadata,<wbr/> the camera device will ignore the sections outside the crop
region and output only the intersection rectangle as the metering region in the result
metadata.<wbr/> If the region is entirely outside the crop region,<wbr/> it will be ignored and
not reported in the result metadata.<wbr/></p>
<p>When setting the AWB metering regions,<wbr/> the application must consider the additional
crop resulted from the aspect ratio differences between the preview stream and
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>.<wbr/> For example,<wbr/> if the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> is the full
active array size with 4:3 aspect ratio,<wbr/> and the preview stream is 16:9,<wbr/>
the boundary of AWB regions will be [0,<wbr/> y_<wbr/>crop] and
[active_<wbr/>width,<wbr/> active_<wbr/>height - 2 * y_<wbr/>crop] rather than [0,<wbr/> 0] and
[active_<wbr/>width,<wbr/> active_<wbr/>height],<wbr/> where y_<wbr/>crop is the additional crop due to aspect ratio
mismatch.<wbr/></p>
<p>Starting from API level 30,<wbr/> the coordinate system of activeArraySize or
preCorrectionActiveArraySize is used to represent post-zoomRatio field of view,<wbr/> not
pre-zoom field of view.<wbr/> This means that the same awbRegions values at different
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> represent different parts of the scene.<wbr/> The awbRegions
coordinates are relative to the activeArray/<wbr/>preCorrectionActiveArray representing the
zoomed field of view.<wbr/> If <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is set to 1.<wbr/>0 (default),<wbr/> the same
awbRegions at different <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> still represent the same parts of
the scene as they do before.<wbr/> See <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> for details.<wbr/> Whether to use
activeArraySize or preCorrectionActiveArraySize still depends on distortion correction
mode.<wbr/></p>

</ul>
<p>For high speed recording use case,<wbr/> the actual maximum supported frame rate may
be lower than what camera can output,<wbr/> depending on the destination Surfaces for
the image data.<wbr/> For example,<wbr/> if the destination surface is from video encoder,<wbr/>
the application need check if the video encoder is capable of supporting the
high frame rate for a given video size,<wbr/> or it will end up with lower recording
frame rate.<wbr/> If the destination surface is from preview window,<wbr/> the preview frame
rate will be bounded by the screen refresh rate.<wbr/></p>
<p>The camera device will only support up to 2 output high speed streams
(processed non-stalling format defined in <a href="#static_android.request.maxNumOutputStreams">android.<wbr/>request.<wbr/>max<wbr/>Num<wbr/>Output<wbr/>Streams</a>)

<span class="entry_type_enum_optional">[optional]</span>
<span class="entry_type_enum_notes"><p>Turn on a device-specific high dynamic range (HDR) mode.<wbr/></p>
<p>In this scene mode,<wbr/> the camera device captures images
that keep a larger range of scene illumination levels
visible in the final image.<wbr/> For example,<wbr/> when taking a
picture of a object in front of a bright window,<wbr/> both
the object and the scene through the window may be
visible when using HDR mode,<wbr/> while in normal AUTO mode,<wbr/>
one or the other may be poorly exposed.<wbr/> As a tradeoff,<wbr/>
HDR mode generally takes much longer to capture a single
image,<wbr/> has no user control,<wbr/> and may have other artifacts
depending on the HDR method used.<wbr/></p>
<p>Therefore,<wbr/> HDR captures operate at a much slower rate
than regular captures.<wbr/></p>
<p>In this mode,<wbr/> on LIMITED or FULL devices,<wbr/> when a request
is made with a <a href="#controls_android.control.captureIntent">android.<wbr/>control.<wbr/>capture<wbr/>Intent</a> of
STILL_<wbr/>CAPTURE,<wbr/> the camera device will capture an image
using a high dynamic range capture technique.<wbr/> On LEGACY
devices,<wbr/> captures that target a JPEG-format output will
be captured with HDR,<wbr/> and the capture intent is not
relevant.<wbr/></p>
<p>The HDR capture may involve the device capturing a burst
of images internally and combining them into one,<wbr/> or it
may involve the device using specialized high dynamic
range capture hardware.<wbr/> In all cases,<wbr/> a single image is
produced in response to a capture request submitted
while in HDR mode.<wbr/></p>
<p>Since substantial post-processing is generally needed to
produce an HDR image,<wbr/> only YUV,<wbr/> PRIVATE,<wbr/> and JPEG
outputs are supported for LIMITED/<wbr/>FULL device HDR
captures,<wbr/> and only JPEG outputs are supported for LEGACY
HDR captures.<wbr/> Using a RAW output for HDR capture is not
supported.<wbr/></p>
<p>Some devices may also support always-on HDR,<wbr/> which
applies HDR processing at full frame rate.<wbr/> For these
devices,<wbr/> intents other than STILL_<wbr/>CAPTURE will also
produce an HDR output with no frame rate impact compared
to normal operation,<wbr/> though the quality may be lower
than for STILL_<wbr/>CAPTURE intents.<wbr/></p>
<p>If SCENE_<wbr/>MODE_<wbr/>HDR is used with unsupported output types
or capture intents,<wbr/> the images captured will be as if
the SCENE_<wbr/>MODE was not enabled at all.<wbr/></p></span>

device will choose higher sensitivity values (<a href="#controls_android.sensor.sensitivity">android.<wbr/>sensor.<wbr/>sensitivity</a>)
under low light conditions.<wbr/></p>
<p>The camera device may be tuned to expose the images in a reduced
sensitivity range to produce the best quality images.<wbr/> For example,<wbr/>
if the <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> gives range of [100,<wbr/> 1600],<wbr/>
the camera device auto-exposure routine tuning process may limit the actual
exposure sensitivity range to [100,<wbr/> 1200] to ensure that the noise level isn't
excessive in order to preserve the image quality.<wbr/> Under this situation,<wbr/> the image under
low light may be under-exposed when the sensor max exposure time (bounded by the
<a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a> when <a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a> is one of the
ON_<wbr/>* modes) and effective max sensitivity are reached.<wbr/> This scene mode allows the
camera device auto-exposure routine to increase the sensitivity up to the max
sensitivity specified by <a href="#static_android.sensor.info.sensitivityRange">android.<wbr/>sensor.<wbr/>info.<wbr/>sensitivity<wbr/>Range</a> when the scene is too
dark and the max exposure time is reached.<wbr/> The captured images may be noisier
compared with the images captured in normal FACE_<wbr/>PRIORITY mode; therefore,<wbr/> it is
recommended that the application only use this scene mode when it is capable of
reducing the noise level of the captured images.<wbr/></p>
<p>Unlike the other scene modes,<wbr/> <a href="#controls_android.control.aeMode">android.<wbr/>control.<wbr/>ae<wbr/>Mode</a>,<wbr/>

request A,<wbr/> and the result metadata for request B may be older than the result metadata for

<p>Instead of using <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> for zoom,<wbr/> the application can now choose to
use this tag to specify the desired zoom level.<wbr/></p>
<p>By using this control,<wbr/> the application gains a simpler way to control zoom,<wbr/> which can
be a combination of optical and digital zoom.<wbr/> For example,<wbr/> a multi-camera system may
contain more than one lens with different focal lengths,<wbr/> and the user can use optical
zoom by switching between lenses.<wbr/> Using zoomRatio has benefits in the scenarios below:</p>
<ul>
<li>Zooming in from a wide-angle lens to a telephoto lens: A floating-point ratio provides
better precision compared to an integer value of <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>.<wbr/></li>
<li>Zooming out from a wide lens to an ultrawide lens: zoomRatio supports zoom-out whereas
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> doesn't.<wbr/></li>
</ul>
<p>To illustrate,<wbr/> here are several scenarios of different zoom ratios,<wbr/> crop regions,<wbr/>
and output streams,<wbr/> for a hypothetical camera device with an active array of size
<code>(2000,<wbr/>1500)</code>.<wbr/></p>
<ul>
<li>Camera Configuration:<ul>
<li>Active array size: <code>2000x1500</code> (3 MP,<wbr/> 4:3 aspect ratio)</li>
<li>Output stream #1: <code>640x480</code> (VGA,<wbr/> 4:3 aspect ratio)</li>
<li>Output stream #2: <code>1280x720</code> (720p,<wbr/> 16:9 aspect ratio)</li>
</ul>
</li>
<li>Case #1: 4:3 crop region with 2.<wbr/>0x zoom ratio<ul>
<li>Zoomed field of view: 1/<wbr/>4 of original field of view</li>
<li>Crop region: <code>Rect(0,<wbr/> 0,<wbr/> 2000,<wbr/> 1500) //<wbr/> (left,<wbr/> top,<wbr/> right,<wbr/> bottom)</code> (post zoom)</li>
</ul>
</li>
<li><img alt="4:3 aspect ratio crop diagram" src="images/camera2/metadata/android.control.zoomRatio/zoom-ratio-2-crop-43.png"/><ul>
<li><code>640x480</code> stream source area: <code>(0,<wbr/> 0,<wbr/> 2000,<wbr/> 1500)</code> (equal to crop region)</li>
<li><code>1280x720</code> stream source area: <code>(0,<wbr/> 187,<wbr/> 2000,<wbr/> 1312)</code> (letterboxed)</li>
</ul>
</li>
<li>Case #2: 16:9 crop region with 2.<wbr/>0x zoom.<wbr/><ul>

<li><img alt="16:9 aspect ratio crop diagram" src="images/camera2/metadata/android.control.zoomRatio/zoom-ratio-2-crop-169.png"/></li>
<li><code>640x480</code> stream source area: <code>(250,<wbr/> 187,<wbr/> 1750,<wbr/> 1312)</code> (pillarboxed)</li>
<li><code>1280x720</code> stream source area: <code>(0,<wbr/> 187,<wbr/> 2000,<wbr/> 1312)</code> (equal to crop region)</li>
</ul>
</li>
<li>Case #3: 1:1 crop region with 0.<wbr/>5x zoom out to ultrawide lens.<wbr/><ul>
<li>Zoomed field of view: 4x of original field of view (switched from wide lens to ultrawide lens)</li>
<li>Crop region: <code>Rect(250,<wbr/> 0,<wbr/> 1750,<wbr/> 1500)</code></li>
<li><img alt="1:1 aspect ratio crop diagram" src="images/camera2/metadata/android.control.zoomRatio/zoom-ratio-0.5-crop-11.png"/></li>
<li><code>640x480</code> stream source area: <code>(250,<wbr/> 187,<wbr/> 1750,<wbr/> 1312)</code> (letterboxed)</li>
<li><code>1280x720</code> stream source area: <code>(250,<wbr/> 328,<wbr/> 1750,<wbr/> 1172)</code> (letterboxed)</li>
</ul>
</li>
</ul>
<p>As seen from the graphs above,<wbr/> the coordinate system of cropRegion now changes to the
effective after-zoom field-of-view,<wbr/> and is represented by the rectangle of (0,<wbr/> 0,<wbr/>
activeArrayWith,<wbr/> activeArrayHeight).<wbr/> The same applies to AE/<wbr/>AWB/<wbr/>AF regions,<wbr/> and faces.<wbr/>
This coordinate system change isn't applicable to RAW capture and its related
metadata such as intrinsicCalibration and lensShadingMap.<wbr/></p>
<p>Using the same hypothetical example above,<wbr/> and assuming output stream #1 (640x480) is
the viewfinder stream,<wbr/> the application can achieve 2.<wbr/>0x zoom in one of two ways:</p>
<ul>
<li>zoomRatio = 2.<wbr/>0,<wbr/> scaler.<wbr/>cropRegion = (0,<wbr/> 0,<wbr/> 2000,<wbr/> 1500)</li>
<li>zoomRatio = 1.<wbr/>0 (default),<wbr/> scaler.<wbr/>cropRegion = (500,<wbr/> 375,<wbr/> 1500,<wbr/> 1125)</li>
</ul>
<p>If the application intends to set aeRegions to be top-left quarter of the viewfinder
field-of-view,<wbr/> the <a href="#controls_android.control.aeRegions">android.<wbr/>control.<wbr/>ae<wbr/>Regions</a> should be set to (0,<wbr/> 0,<wbr/> 1000,<wbr/> 750) with
zoomRatio set to 2.<wbr/>0.<wbr/> Alternatively,<wbr/> the application can set aeRegions to the equivalent
region of (500,<wbr/> 375,<wbr/> 1000,<wbr/> 750) for zoomRatio of 1.<wbr/>0.<wbr/> If the application doesn't
explicitly set <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a>,<wbr/> its value defaults to 1.<wbr/>0.<wbr/></p>
<p>One limitation of controlling zoom using zoomRatio is that the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>
must only be used for letterboxing or pillarboxing of the sensor active array,<wbr/> and no
FREEFORM cropping can be used with <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> other than 1.<wbr/>0.<wbr/> If
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> is not 1.<wbr/>0,<wbr/> and <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> is set to be
windowboxing,<wbr/> the camera framework will override the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> to be
the active array.<wbr/></p>
<p>In the capture request,<wbr/> if the application sets <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> to a
value != 1.<wbr/>0,<wbr/> the <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> tag in the capture result reflects the
effective zoom ratio achieved by the camera device,<wbr/> and the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a>
adjusts for additional crops that are not zoom related.<wbr/> Otherwise,<wbr/> if the application
sets <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> to 1.<wbr/>0,<wbr/> or does not set it at all,<wbr/> the
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> tag in the result metadata will also be 1.<wbr/>0.<wbr/></p>
<p>When the application requests a physical stream for a logical multi-camera,<wbr/> the
<a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> in the physical camera result metadata will be 1.<wbr/>0,<wbr/> and
the <a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> tag reflects the amount of zoom and crop done by the
physical camera device.<wbr/></p>

<p>For best results,<wbr/> when issuing a request for a JPEG image,<wbr/> the thumbnail size selected
should have the same aspect ratio as the main JPEG output.<wbr/></p>
<p>If the thumbnail image aspect ratio differs from the JPEG primary image aspect
ratio,<wbr/> the camera device creates the thumbnail by cropping it from the primary image.<wbr/>
For example,<wbr/> if the primary image has 4:3 aspect ratio,<wbr/> the thumbnail image has
16:9 aspect ratio,<wbr/> the primary image will be cropped vertically (letterbox) to
generate the thumbnail image.<wbr/> The thumbnail image will always have a smaller Field

<p>When an <a href="#controls_android.jpeg.orientation">android.<wbr/>jpeg.<wbr/>orientation</a> of non-zero degree is requested,<wbr/>

<ul>
<li>Set the <a href="https://developer.android.com/reference/android/media/ExifInterface.html#TAG_ORIENTATION">EXIF orientation flag</a>
and keep jpeg and thumbnail image data unrotated.<wbr/></li>
<li>Rotate the jpeg and thumbnail image data and not set
<a href="https://developer.android.com/reference/android/media/ExifInterface.html#TAG_ORIENTATION">EXIF orientation flag</a>.<wbr/> In this
case,<wbr/> LIMITED or FULL hardware level devices will report rotated thumbnail size in
capture result,<wbr/> so the width and height will be interchanged if 90 or 270 degree
orientation is requested.<wbr/> LEGACY device will always report unrotated thumbnail
size.<wbr/></li>
</ul>
<p>The tag is also used as thumbnail size for HEIC image format capture,<wbr/> in which case the

<p>For best results,<wbr/> when issuing a request for a JPEG image,<wbr/> the thumbnail size selected

<p>If the thumbnail image aspect ratio differs from the JPEG primary image aspect
ratio,<wbr/> the camera device creates the thumbnail by cropping it from the primary image.<wbr/>

<li>Set the <a href="https://developer.android.com/reference/android/media/ExifInterface.html#TAG_ORIENTATION">EXIF orientation flag</a>

orientation is requested.<wbr/> LEGACY device will always report unrotated thumbnail

<p>These are typically used within a transformation matrix K:</p>

<p>(Note the negation of poseTranslation when mapping from camera

(depth) in pixel coordinates.<wbr/></p>
<p>Note that the coordinate system for this transform is the
<a href="#static_android.sensor.info.preCorrectionActiveArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pre<wbr/>Correction<wbr/>Active<wbr/>Array<wbr/>Size</a> system,<wbr/>

intrinsic calibration transforms have been applied to a

<p>For camera devices,<wbr/> the center of pixel <code>(x,<wbr/>y)</code> is located at

<p>Finally,<wbr/> <code>r</code> represents the radial distance from the

<p>OIS is used to compensate for motion blur due to small
movements of the camera during capture.<wbr/> Unlike digital image
stabilization (<a href="#controls_android.control.videoStabilizationMode">android.<wbr/>control.<wbr/>video<wbr/>Stabilization<wbr/>Mode</a>),<wbr/> OIS
makes use of mechanical elements to stabilize the camera
sensor,<wbr/> and thus allows for longer exposure times before
camera shake becomes apparent.<wbr/></p>
<p>Switching between different optical stabilization modes may take several
frames to initialize,<wbr/> the camera device will report the current mode in
capture result metadata.<wbr/> For example,<wbr/> When "ON" mode is requested,<wbr/> the
optical stabilization modes in the first several capture results may still
be "OFF",<wbr/> and it will become "ON" when the initialization is done.<wbr/></p>
<p>If a camera device supports both OIS and digital image stabilization
(<a href="#controls_android.control.videoStabilizationMode">android.<wbr/>control.<wbr/>video<wbr/>Stabilization<wbr/>Mode</a>),<wbr/> turning both modes on may produce undesirable
interaction,<wbr/> so it is recommended not to enable both at the same time.<wbr/></p>

to turn on hardware based image stabilization in addition to software based stabilization
if it deems that appropriate.<wbr/> This key's value in the capture result will reflect which
OIS mode was chosen.<wbr/></p>

<p>For camera devices,<wbr/> the center of pixel <code>(x,<wbr/>y)</code> is located at

<code>[kappa_<wbr/>4,<wbr/> kappa_<wbr/>5]</code> that can be used to correct the
lens's geometric distortion with the mapping equations:</p>
<pre><code> x_<wbr/>c = x_<wbr/>i * ( 1 + kappa_<wbr/>1 * r^2 + kappa_<wbr/>2 * r^4 + kappa_<wbr/>3 * r^6 ) +
kappa_<wbr/>4 * (2 * x_<wbr/>i * y_<wbr/>i) + kappa_<wbr/>5 * ( r^2 + 2 * x_<wbr/>i^2 )
y_<wbr/>c = y_<wbr/>i * ( 1 + kappa_<wbr/>1 * r^2 + kappa_<wbr/>2 * r^4 + kappa_<wbr/>3 * r^6 ) +
kappa_<wbr/>5 * (2 * x_<wbr/>i * y_<wbr/>i) + kappa_<wbr/>4 * ( r^2 + 2 * y_<wbr/>i^2 )
</code></pre>
<p>Here,<wbr/> <code>[x_<wbr/>c,<wbr/> y_<wbr/>c]</code> are the coordinates to sample in the
input image that correspond to the pixel values in the
corrected image at the coordinate <code>[x_<wbr/>i,<wbr/> y_<wbr/>i]</code>:</p>
<pre><code> correctedImage(x_<wbr/>i,<wbr/> y_<wbr/>i) = sample_<wbr/>at(x_<wbr/>c,<wbr/> y_<wbr/>c,<wbr/> inputImage)
</code></pre>
<p>The pixel coordinates are defined in a coordinate system
related to the <a href="#static_android.lens.intrinsicCalibration">android.<wbr/>lens.<wbr/>intrinsic<wbr/>Calibration</a>
calibration fields; see that entry for details of the mapping stages.<wbr/>
Both <code>[x_<wbr/>i,<wbr/> y_<wbr/>i]</code> and <code>[x_<wbr/>c,<wbr/> y_<wbr/>c]</code>
have <code>(0,<wbr/>0)</code> at the lens optical center <code>[c_<wbr/>x,<wbr/> c_<wbr/>y]</code>,<wbr/> and
the range of the coordinates depends on the focal length
terms of the intrinsic calibration.<wbr/></p>
<p>Finally,<wbr/> <code>r</code> represents the radial distance from the
optical center,<wbr/> <code>r^2 = x_<wbr/>i^2 + y_<wbr/>i^2</code>.<wbr/></p>
<p>The distortion model used is the Brown-Conrady model.<wbr/></p>

the camera device.<wbr/> Using more streams simultaneously may require more hardware and
CPU resources that will consume more power.<wbr/> The image format for this kind of an output stream can
be any non-<code>RAW</code> and supported format provided by <a href="#static_android.scaler.streamConfigurationMap">android.<wbr/>scaler.<wbr/>stream<wbr/>Configuration<wbr/>Map</a>.<wbr/></p>
<p>A processed and stalling format is defined as any non-RAW format with a stallDurations
&gt; 0.<wbr/> Typically only the <a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#JPEG">JPEG format</a> is a stalling format.<wbr/></p>
<p>For full guarantees,<wbr/> query <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a> with a
processed format -- it will return a non-0 value for a stalling stream.<wbr/></p>
<p>LEGACY devices will support up to 1 processing/<wbr/>stalling stream.<wbr/></p>

<p>The field of view of non-RAW physical streams must not be smaller than that of the
non-RAW logical streams,<wbr/> or the maximum field-of-view of the physical camera,<wbr/>
whichever is smaller.<wbr/> The application should check the physical capture result
metadata for how the physical streams are cropped or zoomed.<wbr/> More specifically,<wbr/> given
the physical camera result metadata,<wbr/> the effective horizontal field-of-view of the
physical camera is:</p>
<pre><code>fov = 2 * atan2(cropW * sensorW /<wbr/> (2 * zoomRatio * activeArrayW),<wbr/> focalLength)
</code></pre>
<p>where the equation parameters are the physical camera's crop region width,<wbr/> physical
sensor width,<wbr/> zoom ratio,<wbr/> active array width,<wbr/> and focal length respectively.<wbr/> Typically
the physical stream of active physical camera has the same field-of-view as the
logical streams.<wbr/> However,<wbr/> the same may not be true for physical streams from
non-active physical cameras.<wbr/> For example,<wbr/> if the logical camera has a wide-ultrawide
configuration where the wide lens is the default,<wbr/> when the crop region is set to the
logical camera's active array size,<wbr/> (and the zoom ratio set to 1.<wbr/>0 starting from
Android 11),<wbr/> a physical stream for the ultrawide camera may prefer outputting images
with larger field-of-view than that of the wide camera for better stereo matching
margin or more robust motion tracking.<wbr/> At the same time,<wbr/> the physical non-RAW streams'
field of view must not be smaller than the requested crop region and zoom ratio,<wbr/> as
long as it's within the physical lens' capability.<wbr/> For example,<wbr/> for a logical camera
with wide-tele lens configuration where the wide lens is the default,<wbr/> if the logical
camera's crop region is set to maximum size,<wbr/> and zoom ratio set to 1.<wbr/>0,<wbr/> the physical
stream for the tele lens will be configured to its maximum size crop region (no zoom).<wbr/></p>
<p><em>Deprecated:</em> Prior to Android 11,<wbr/> the field of view of all non-RAW physical streams
cannot be larger than that of non-RAW logical streams.<wbr/> If the logical camera has a
wide-ultrawide lens configuration where the wide lens is the default,<wbr/> when the logical
camera's crop region is set to maximum size,<wbr/> the FOV of the physical streams for the
ultrawide lens will be the same as the logical stream,<wbr/> by making the crop region
smaller than its active array size to compensate for the smaller focal length.<wbr/></p>
<p>For a logical camera,<wbr/> typically the underlying physical cameras have different RAW
capabilities (such as resolution or CFA pattern).<wbr/> There are two ways for the
application to capture RAW images from the logical camera:</p>
<ul>
<li>If the logical camera has RAW capability,<wbr/> the application can create and use RAW
streams in the same way as before.<wbr/> In case a RAW stream is configured,<wbr/> to maintain
backward compatibility,<wbr/> the camera device makes sure the default active physical
camera remains active and does not switch to other physical cameras.<wbr/> (One exception
is that,<wbr/> if the logical camera consists of identical image sensors and advertises
multiple focalLength due to different lenses,<wbr/> the camera device may generate RAW
images from different physical cameras based on the focalLength being set by the
application.<wbr/>) This backward-compatible approach usually results in loss of optical
zoom,<wbr/> to telephoto lens or to ultrawide lens.<wbr/></li>
<li>Alternatively,<wbr/> if supported by the device,<wbr/>
<a href="https://developer.android.com/reference/android/hardware/camera2/MultiResolutionImageReader.html">MultiResolutionImageReader</a>
can be used to capture RAW images from one of the underlying physical cameras (
depending on current zoom level).<wbr/> Because different physical cameras may have
different RAW characteristics,<wbr/> the application needs to use the characteristics
and result metadata of the active physical camera for the relevant RAW metadata.<wbr/></li>
</ul>
<p>The capture request and result metadata tags required for backward compatible camera
functionalities will be solely based on the logical camera capability.<wbr/> On the other
hand,<wbr/> the use of manual capture controls (sensor or post-processing) with a
logical camera may result in unexpected behavior when the HAL decides to switch
between physical cameras with different characteristics under the hood.<wbr/> For example,<wbr/>
when the application manually sets exposure time and sensitivity while zooming in,<wbr/>
the brightness of the camera images may suddenly change because HAL switches from one
physical camera to the other.<wbr/></p></span>

<p>For a camera device with LOGICAL_<wbr/>MULTI_<wbr/>CAMERA capability,<wbr/> it should operate in the
same way as a physical camera device based on its hardware level and capabilities.<wbr/>
It's recommended that its feature set is superset of that of individual physical cameras.<wbr/></p>
<ul>
<li>
<p>In camera1 API,<wbr/> to maintain application compatibility,<wbr/> for each camera facing,<wbr/> there
may be one or more {logical_<wbr/>camera_<wbr/>id,<wbr/> physical_<wbr/>camera_<wbr/>1_<wbr/>id,<wbr/> physical_<wbr/>camera_<wbr/>2_<wbr/>id,<wbr/> ...<wbr/>}
combinations,<wbr/> where logical_<wbr/>camera_<wbr/>id is composed of physical_<wbr/>camera_<wbr/>N_<wbr/>id,<wbr/> camera
framework will only advertise one camera id
(within the combinations for the particular facing) that is frontmost in the HAL
published camera id list.<wbr/>
For example,<wbr/> if HAL advertises 6 back facing camera IDs (ID0 to ID5),<wbr/> among which ID4
and ID5 are logical cameras backed by ID0+ID1 and ID2+ID3 respectively.<wbr/> In this case,<wbr/>
only ID0 will be available for camera1 API to use.<wbr/></p>
</li>
<li>
<p>Camera HAL is strongly recommended to advertise camera devices with best feature,<wbr/>
power,<wbr/> performance,<wbr/> and latency tradeoffs at the front of the camera id list.<wbr/></p>
</li>
<li>
<p>Camera HAL may switch between physical cameras depending on focalLength,<wbr/> cropRegion,<wbr/> or
zoomRatio.<wbr/> If physical cameras have different sizes,<wbr/> HAL must maintain a single logical
camera active<wbr/>Array<wbr/>Size/<wbr/>pixel<wbr/>Array<wbr/>Size/<wbr/>pre<wbr/>Correction<wbr/>Active<wbr/>Array<wbr/>Size,<wbr/> and must do proper
mapping between logical camera and underlying physical cameras for all related metadata
tags,<wbr/> such as crop region,<wbr/> zoomRatio,<wbr/> 3A regions,<wbr/> and intrinsicCalibration.<wbr/></p>
</li>
<li>
<p>Starting from HIDL ICameraDevice version 3.<wbr/>5,<wbr/> camera HAL must support
isStreamCombinationSupported for application to query whether a particular logical and
physical streams combination are supported.<wbr/></p>
</li>
</ul>
<p>A MONOCHROME camera device must also advertise BACKWARD_<wbr/>COMPATIBLE capability,<wbr/> and must
not advertise MANUAL_<wbr/>POST_<wbr/>PROCESSING capability.<wbr/></p>
<ul>
<li>
<p>To maintain backward compatibility,<wbr/> the camera device must support all
BACKWARD_<wbr/>COMPATIBLE required keys.<wbr/> The <a href="#static_android.control.awbAvailableModes">android.<wbr/>control.<wbr/>awb<wbr/>Available<wbr/>Modes</a> key only contains
AUTO,<wbr/> and <a href="#dynamic_android.control.awbState">android.<wbr/>control.<wbr/>awb<wbr/>State</a> are either CONVERGED or LOCKED depending on

<a href="#controls_android.colorCorrection.gains">android.<wbr/>color<wbr/>Correction.<wbr/>gains</a> must not be in available request and result keys.<wbr/>
As a result,<wbr/> the camera device cannot be a FULL device.<wbr/> However,<wbr/> the HAL can
still advertise other individual capabilities.<wbr/></p>
</li>
<li>
<p>If the device supports tonemap control,<wbr/> only <a href="#controls_android.tonemap.curveRed">android.<wbr/>tonemap.<wbr/>curve<wbr/>Red</a> is used.<wbr/>
CurveGreen and curveBlue are no-ops.<wbr/></p>
</li>
</ul>
<p>In Android API level 28,<wbr/> a MONOCHROME camera device must not have RAW capability.<wbr/> From
API level 29,<wbr/> a camera is allowed to have both MONOCHROME and RAW capabilities.<wbr/></p>
<p>To support the legacy API to ICameraDevice 3.<wbr/>x shim layer,<wbr/> devices advertising
OFFLINE_<wbr/>PROCESSING capability must also support configuring an input stream of the same
size as the picture size if:</p>
<ul>
<li>The device supports PRIVATE_<wbr/>REPROCESSING capability</li>
<li>The device's maximal JPEG resolution can reach 30 FPS min frame duration</li>
<li>The device does not support HAL based ZSL (<a href="#controls_android.control.enableZsl">android.<wbr/>control.<wbr/>enable<wbr/>Zsl</a>)</li>
</ul>
<p>For devices which support SYSTEM_<wbr/>CAMERA and LOGICAL_<wbr/>MULTI_<wbr/>CAMERA capabilities:</p>

<p>This is a subset of <a href="#static_android.request.availableRequestKeys">android.<wbr/>request.<wbr/>available<wbr/>Request<wbr/>Keys</a> which
contains a list of keys that are difficult to apply per-frame and
can result in unexpected delays when modified during the capture session
lifetime.<wbr/> Typical examples include parameters that require a
time-consuming hardware re-configuration or internal camera pipeline
change.<wbr/> For performance reasons we advise clients to pass their initial
values as part of
<a href="https://developer.android.com/reference/SessionConfiguration.html#setSessionParameters">SessionConfiguration#setSessionParameters</a>.<wbr/>
Once the camera capture session is enabled it is also recommended to avoid
changing them from their initial values set in
<a href="https://developer.android.com/reference/SessionConfiguration.html#setSessionParameters">SessionConfiguration#setSessionParameters</a>.<wbr/>
Control over session parameters can still be exerted in capture requests
but clients should be aware and expect delays during their application.<wbr/>
An example usage scenario could look like this:</p>
<ul>
<li>The camera client starts by querying the session parameter key list via
<a href="https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html#getAvailableSessionKeys">CameraCharacteristics#getAvailableSessionKeys</a>.<wbr/></li>
<li>Before triggering the capture session create sequence,<wbr/> a capture request
must be built via
<a href="https://developer.android.com/reference/CameraDevice.html#createCaptureRequest">CameraDevice#createCaptureRequest</a>
using an appropriate template matching the particular use case.<wbr/></li>
<li>The client should go over the list of session parameters and check
whether some of the keys listed matches with the parameters that
they intend to modify as part of the first capture request.<wbr/></li>
<li>If there is no such match,<wbr/> the capture request can be passed
unmodified to
<a href="https://developer.android.com/reference/SessionConfiguration.html#setSessionParameters">SessionConfiguration#setSessionParameters</a>.<wbr/></li>
<li>If matches do exist,<wbr/> the client should update the respective values
and pass the request to
<a href="https://developer.android.com/reference/SessionConfiguration.html#setSessionParameters">SessionConfiguration#setSessionParameters</a>.<wbr/></li>
<li>After the capture session initialization completes the session parameter
key list can continue to serve as reference when posting or updating
further requests.<wbr/> As mentioned above further changes to session
parameters should ideally be avoided,<wbr/> if updates are necessary
however clients could expect a delay/<wbr/>glitch during the
parameter switch.<wbr/></li>

1) The supported dynamic profile value.<wbr/> Do note that
ANDROID_<wbr/>REQUEST_<wbr/>AVAILABLE_<wbr/>DYNAMIC_<wbr/>RANGE_<wbr/>PROFILES_<wbr/>STANDARD is assumed to be always
present and must not be listed.<wbr/>
2) A bitmap combination of all supported profiles that can be referenced at the same
time within a single capture request.<wbr/> Do note that a value of 0 means that there are
no constraints and all combinations are supported.<wbr/>
3) A flag indicating the presence of an internal lookahead functionality that
can increase the streaming latency by more than 3 buffers.<wbr/> The value 0 will indicate
that latency doesn't exceed 3 buffers,<wbr/> everything different than 0 will indicate
latency that is beyond 3 buffers.<wbr/> In case the flag is set,<wbr/> then Camera clients will be
advised to avoid configuring this profile for camera latency sensitive outputs such as
preview.<wbr/> Do note,<wbr/> that such extra latency must not be present for the HLG10 profile.<wbr/></p>
<p>For example if we assume that a device exists that can only support HLG10,<wbr/> HDR10 and
HDR10_<wbr/>PLUS from the possible 10-bit profiles with the following capture constraints:
1) HLG10 can be included in any capture request without constraints.<wbr/>
2) HDR10 and HDR10_<wbr/>PLUS can only be referenced together and/<wbr/>or with HLG10 but not with
STANDARD.<wbr/>
In the same example,<wbr/> HLG10 and HDR10 will not have additional lookahead latency,<wbr/> and
HDR10+ will have latency that exceeds 3 buffers.<wbr/>
The resulting array should look like this:

<p>For devices supporting <a href="#controls_android.distortionCorrection.mode">android.<wbr/>distortion<wbr/>Correction.<wbr/>mode</a> control,<wbr/> the coordinate system
depends on the mode being set.<wbr/> When the distortion correction mode is OFF,<wbr/> the
coordinate system follows <a href="#static_android.sensor.info.preCorrectionActiveArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pre<wbr/>Correction<wbr/>Active<wbr/>Array<wbr/>Size</a>,<wbr/> with <code>(0,<wbr/>

<p>Output streams use this rectangle to produce their output,<wbr/> cropping to a smaller region
if necessary to maintain the stream's aspect ratio,<wbr/> then scaling the sensor input to
match the output's configured resolution.<wbr/></p>
<p>The crop region is applied after the RAW to other color space (e.<wbr/>g.<wbr/> YUV)
conversion.<wbr/> Since raw streams (e.<wbr/>g.<wbr/> RAW16) don't have the conversion stage,<wbr/> they are not
croppable.<wbr/> The crop region will be ignored by raw streams.<wbr/></p>
<p>For non-raw streams,<wbr/> any additional per-stream cropping will be done to maximize the
final pixel area of the stream.<wbr/></p>
<p>For example,<wbr/> if the crop region is set to a 4:3 aspect ratio,<wbr/> then 4:3 streams will use
the exact crop region.<wbr/> 16:9 streams will further crop vertically (letterbox).<wbr/></p>
<p>Conversely,<wbr/> if the crop region is set to a 16:9,<wbr/> then 4:3 outputs will crop horizontally
(pillarbox),<wbr/> and 16:9 streams will match exactly.<wbr/> These additional crops will be
centered within the crop region.<wbr/></p>
<p>To illustrate,<wbr/> here are several scenarios of different crop regions and output streams,<wbr/>
for a hypothetical camera device with an active array of size <code>(2000,<wbr/>1500)</code>.<wbr/> Note that
several of these examples use non-centered crop regions for ease of illustration; such
regions are only supported on devices with FREEFORM capability
(<a href="#static_android.scaler.croppingType">android.<wbr/>scaler.<wbr/>cropping<wbr/>Type</a> <code>== FREEFORM</code>),<wbr/> but this does not affect the way the crop
rules work otherwise.<wbr/></p>

<p>The camera device may adjust the crop region to account for rounding and other hardware
requirements; the final crop region used will be included in the output capture result.<wbr/></p>
<p>The camera sensor output aspect ratio depends on factors such as output stream
combination and <a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a>,<wbr/> and shouldn't be adjusted by using
this control.<wbr/> And the camera device will treat different camera sensor output sizes
(potentially with in-sensor crop) as the same crop of
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/> As a result,<wbr/> the application shouldn't assume the
maximum crop region always maps to the same aspect ratio or field of view for the
sensor output.<wbr/></p>
<p>Starting from API level 30,<wbr/> it's strongly recommended to use <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a>
to take advantage of better support for zoom with logical multi-camera.<wbr/> The benefits
include better precision with optical-digital zoom combination,<wbr/> and ability to do
zoom-out from 1.<wbr/>0x.<wbr/> When using <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> for zoom,<wbr/> the crop region in
the capture request should be left as the default activeArray size.<wbr/> The
coordinate system is post-zoom,<wbr/> meaning that the activeArraySize or
preCorrectionActiveArraySize covers the camera device's field of view "after" zoom.<wbr/> See

<p>This control is primarily intended to help camera applications with no support for
multi-window modes to work correctly on devices where multi-window scenarios are
unavoidable,<wbr/> such as foldables or other devices with variable display geometry or more
free-form window placement (such as laptops,<wbr/> which often place portrait-orientation apps
in landscape with pillarboxing).<wbr/></p>
<p>If supported,<wbr/> the default value is <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>AUTO</code>,<wbr/> which allows the camera API
to enable backwards-compatibility support for applications that do not support resizing
/<wbr/> multi-window modes,<wbr/> when the device is in fact in a multi-window mode (such as inset
portrait on laptops,<wbr/> or on a foldable device in some fold states).<wbr/> In addition,<wbr/>
<code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>NONE</code> and <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>90</code> will always be available if this control
is supported by the device.<wbr/> If not supported,<wbr/> devices API level 30 or higher will always
list only <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>NONE</code>.<wbr/></p>
<p>When <code>CROP_<wbr/>AUTO</code> is in use,<wbr/> and the camera API activates backward-compatibility mode,<wbr/>
several metadata fields will also be parsed differently to ensure that coordinates are
correctly handled for features like drawing face detection boxes or passing in
tap-to-focus coordinates.<wbr/> The camera API will convert positions in the active array
coordinate system to/<wbr/>from the cropped-and-rotated coordinate system to make the
operation transparent for applications.<wbr/> The following controls are affected:</p>
<ul>
<li><a href="#controls_android.control.aeRegions">android.<wbr/>control.<wbr/>ae<wbr/>Regions</a></li>
<li><a href="#controls_android.control.afRegions">android.<wbr/>control.<wbr/>af<wbr/>Regions</a></li>

<li><a href="#dynamic_android.statistics.faces">android.<wbr/>statistics.<wbr/>faces</a></li>
</ul>
<p>Capture results will contain the actual value selected by the API;
<code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>AUTO</code> will never be seen in a capture result.<wbr/></p>
<p>Applications can also select their preferred cropping mode,<wbr/> either to opt out of the
backwards-compatibility treatment,<wbr/> or to use the cropping feature themselves as needed.<wbr/>
In this case,<wbr/> no coordinate translation will be done automatically,<wbr/> and all controls
will continue to use the normal active array coordinates.<wbr/></p>
<p>Cropping and rotating is done after the application of digital zoom (via either
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> or <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a>),<wbr/> but before each individual
output is further cropped and scaled.<wbr/> It only affects processed outputs such as
YUV,<wbr/> PRIVATE,<wbr/> and JPEG.<wbr/> It has no effect on RAW outputs.<wbr/></p>
<p>When <code>CROP_<wbr/>90</code> or <code>CROP_<wbr/>270</code> are selected,<wbr/> there is a significant loss to the field of
view.<wbr/> For example,<wbr/> with a 4:3 aspect ratio output of 1600x1200,<wbr/> <code>CROP_<wbr/>90</code> will still
produce 1600x1200 output,<wbr/> but these buffers are cropped from a vertical 3:4 slice at the
center of the 4:3 area,<wbr/> then rotated to be 4:3,<wbr/> and then upscaled to 1600x1200.<wbr/> Only
56.<wbr/>25% of the original FOV is still visible.<wbr/> In general,<wbr/> for an aspect ratio of <code>w:h</code>,<wbr/>
the crop and rotate operation leaves <code>(h/<wbr/>w)^2</code> of the field of view visible.<wbr/> For 16:9,<wbr/>
this is ~31.<wbr/>6%.<wbr/></p>
<p>As a visual example,<wbr/> the figure below shows the effect of <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>90</code> on the
outputs for the following parameters:</p>
<ul>
<li>Sensor active array: <code>2000x1500</code></li>
<li>Crop region: top-left: <code>(500,<wbr/> 375)</code>,<wbr/> size: <code>(1000,<wbr/> 750)</code> (4:3 aspect ratio)</li>
<li>Output streams: YUV <code>640x480</code> and YUV <code>1280x720</code></li>
<li><code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>90</code></li>
</ul>
<p><img alt="Effect of ROTATE_AND_CROP_90" src="images/camera2/metadata/android.scaler.rotateAndCrop/crop-region-rotate-90-43-ratio.png"/></p>
<p>With these settings,<wbr/> the regions of the active array covered by the output streams are:</p>
<ul>
<li>640x480 stream crop: top-left: <code>(219,<wbr/> 375)</code>,<wbr/> size: <code>(562,<wbr/> 750)</code></li>
<li>1280x720 stream crop: top-left: <code>(289,<wbr/> 375)</code>,<wbr/> size: <code>(422,<wbr/> 750)</code></li>
</ul>
<p>Since the buffers are rotated,<wbr/> the buffers as seen by the application are:</p>
<ul>
<li>640x480 stream: top-left: <code>(781,<wbr/> 375)</code> on active array,<wbr/> size: <code>(640,<wbr/> 480)</code>,<wbr/> downscaled 1.<wbr/>17x from sensor pixels</li>

<p>It is recommended (but not mandatory) to also include half/<wbr/>quarter
of sensor maximum resolution for JPEG formats (regardless of hardware
level).<wbr/></p>
<p>(The following is a rewording of the above required table):</p>
<p>For JPEG format,<wbr/> the sizes may be restricted by below conditions:</p>
<ul>
<li>The HAL may choose the aspect ratio of each Jpeg size to be one of well known ones
(e.<wbr/>g.<wbr/> 4:3,<wbr/> 16:9,<wbr/> 3:2 etc.<wbr/>).<wbr/> If the sensor maximum resolution
(defined by <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>) has an aspect ratio other than these,<wbr/>
it does not have to be included in the supported JPEG sizes.<wbr/></li>
<li>Some hardware JPEG encoders may have pixel boundary alignment requirements,<wbr/> such as
the dimensions being a multiple of 16.<wbr/></li>
</ul>
<p>Therefore,<wbr/> the maximum JPEG size may be smaller than sensor maximum resolution.<wbr/>
However,<wbr/> the largest JPEG size must be as close as possible to the sensor maximum
resolution given above constraints.<wbr/> It is required that after aspect ratio adjustments,<wbr/>
additional size reduction due to other issues must be less than 3% in area.<wbr/> For example,<wbr/>
if the sensor maximum resolution is 3280x2464,<wbr/> if the maximum JPEG size has aspect
ratio 4:3,<wbr/> the JPEG encoder alignment requirement is 16,<wbr/> the maximum JPEG size will be
3264x2448.<wbr/></p>
<p>For FULL capability devices (<code><a href="#static_android.info.supportedHardwareLevel">android.<wbr/>info.<wbr/>supported<wbr/>Hardware<wbr/>Level</a> == FULL</code>),<wbr/>
the HAL must include all YUV_<wbr/>420_<wbr/>888 sizes that have JPEG sizes listed
here as output streams.<wbr/></p>
<p>It must also include each below resolution if it is smaller than or
equal to the sensor maximum resolution (for both YUV_<wbr/>420_<wbr/>888 and JPEG
formats),<wbr/> as output streams:</p>
<ul>
<li>240p (320 x 240)</li>
<li>480p (640 x 480)</li>
<li>720p (1280 x 720)</li>
<li>1080p (1920 x 1080)</li>
</ul>
<p>Note that for primary cameras (first rear/<wbr/>front facing camera in the camera ID list)
on a device with <a href="https://developer.android.com/reference/android/os/Build.VERSION.html#MEDIA_PERFORMANCE_CLASS">VERSION#MEDIA_<wbr/>PERFORMANCE_<wbr/>CLASS</a> set to
31 or larger,<wbr/> camera framework filters out JPEG sizes smaller than 1080p depending on
applications' targetSdkLevel.<wbr/> The camera HAL must still support the smaller JPEG sizes
to maintain backward compatibility.<wbr/></p>
<p>For LIMITED capability devices
(<code><a href="#static_android.info.supportedHardwareLevel">android.<wbr/>info.<wbr/>supported<wbr/>Hardware<wbr/>Level</a> == LIMITED</code>),<wbr/>
the HAL only has to list up to the maximum video size
supported by the device.<wbr/></p>
<p>Regardless of hardware level,<wbr/> every output resolution available for
YUV_<wbr/>420_<wbr/>888 must also be available for IMPLEMENTATION_<wbr/>DEFINED.<wbr/></p>

<p>A stall duration is how much extra time would get added
to the normal minimum frame duration for a repeating request
that has streams with non-zero stall.<wbr/></p>
<p>For example,<wbr/> consider JPEG captures which have the following
characteristics:</p>
<ul>
<li>JPEG streams act like processed YUV streams in requests for which
they are not included; in requests in which they are directly
referenced,<wbr/> they act as JPEG streams.<wbr/> This is because supporting a
JPEG stream requires the underlying YUV data to always be ready for
use by a JPEG encoder,<wbr/> but the encoder will only be used (and impact
frame duration) on requests that actually reference a JPEG stream.<wbr/></li>
<li>The JPEG processor can run concurrently to the rest of the camera
pipeline,<wbr/> but cannot process more than 1 capture at a time.<wbr/></li>
</ul>
<p>In other words,<wbr/> using a repeating YUV request would result
in a steady frame rate (let's say it's 30 FPS).<wbr/> If a single
JPEG request is submitted periodically,<wbr/> the frame rate will stay
at 30 FPS (as long as we wait for the previous JPEG to return each
time).<wbr/> If we try to submit a repeating YUV + JPEG request,<wbr/> then
the frame rate will drop from 30 FPS.<wbr/></p>
<p>In general,<wbr/> submitting a new request with a non-0 stall time
stream will <em>not</em> cause a frame rate drop unless there are still
outstanding buffers for that stream from previous requests.<wbr/></p>
<p>Submitting a repeating request with streams (call this <code>S</code>)
is the same as setting the minimum frame duration from
the normal minimum frame duration corresponding to <code>S</code>,<wbr/> added with
the maximum stall duration for <code>S</code>.<wbr/></p>
<p>If interleaving requests with and without a stall duration,<wbr/>
a request will stall by the maximum of the remaining times
for each can-stall stream with outstanding buffers.<wbr/></p>
<p>This means that a stalling request will not have an exposure start
until the stall has completed.<wbr/></p>
<p>This should correspond to the stall duration when only that stream is
active,<wbr/> with all processing (typically in android.<wbr/>*.<wbr/>mode) set to FAST
or OFF.<wbr/> Setting any of the processing modes to HIGH_<wbr/>QUALITY
effectively results in an indeterminate stall duration for all
streams in a request (the regular stall calculation rules are
ignored).<wbr/></p>
<p>The following formats may always have a stall duration:</p>
<ul>
<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#JPEG">ImageFormat#JPEG</a></li>
<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#RAW_SENSOR">ImageFormat#RAW_<wbr/>SENSOR</a></li>
</ul>
<p>The following formats will never have a stall duration:</p>
<ul>
<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#YUV_420_888">Image<wbr/>Format#YUV_<wbr/>420_<wbr/>888</a></li>

<li><a href="https://developer.android.com/reference/android/graphics/ImageFormat.html#Y8">ImageFormat#Y8</a></li>
</ul>
<p>All other formats may or may not have an allowed stall duration on
a per-capability basis; refer to <a href="#static_android.request.availableCapabilities">android.<wbr/>request.<wbr/>available<wbr/>Capabilities</a>

<p>For applications targeting SDK version 31 or newer,<wbr/> if the mobile device doesn't declare

<a href="https://developer.android.com/reference/android/os/Build.VERSION.html#MEDIA_PERFORMANCE_CLASS">VERSION#MEDIA_<wbr/>PERFORMANCE_<wbr/>CLASS</a> to be 31 or larger,<wbr/>
or if the camera device isn't a primary rear/<wbr/>front camera,<wbr/> the minimum required output
stream configurations are the same as for applications targeting SDK version older than
31.<wbr/></p>
<p>Refer to <a href="#static_android.request.availableCapabilities">android.<wbr/>request.<wbr/>available<wbr/>Capabilities</a> and <a href="https://developer.android.com/reference/android/hardware/camera2/CameraDevice.html#createCaptureSession">CameraDevice#createCaptureSession</a> for additional mandatory
stream configurations on a per-capability basis.<wbr/></p>
<p>*1: For JPEG format,<wbr/> the sizes may be restricted by below conditions:</p>
<ul>
<li>The HAL may choose the aspect ratio of each Jpeg size to be one of well known ones
(e.<wbr/>g.<wbr/> 4:3,<wbr/> 16:9,<wbr/> 3:2 etc.<wbr/>).<wbr/> If the sensor maximum resolution
(defined by <a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>) has an aspect ratio other than these,<wbr/>
it does not have to be included in the supported JPEG sizes.<wbr/></li>
<li>Some hardware JPEG encoders may have pixel boundary alignment requirements,<wbr/> such as
the dimensions being a multiple of 16.<wbr/>
Therefore,<wbr/> the maximum JPEG size may be smaller than sensor maximum resolution.<wbr/>
However,<wbr/> the largest JPEG size will be as close as possible to the sensor maximum
resolution given above constraints.<wbr/> It is required that after aspect ratio adjustments,<wbr/>
additional size reduction due to other issues must be less than 3% in area.<wbr/> For example,<wbr/>
if the sensor maximum resolution is 3280x2464,<wbr/> if the maximum JPEG size has aspect
ratio 4:3,<wbr/> and the JPEG encoder alignment requirement is 16,<wbr/> the maximum JPEG size will be
3264x2448.<wbr/></li>
</ul>
<p>Exception on 176x144 (QCIF) resolution: camera devices usually have a fixed capability on
downscaling from larger resolution to smaller ones,<wbr/> and the QCIF resolution can sometimes
not be fully supported due to this limitation on devices with high-resolution image
sensors.<wbr/> Therefore,<wbr/> trying to configure a QCIF resolution stream together with any other
stream larger than 1920x1080 resolution (either width or height) might not be supported,<wbr/>
and capture session creation will fail if it is not.<wbr/></p>

<p>It is recommended (but not mandatory) to also include half/<wbr/>quarter
of sensor maximum resolution for JPEG formats (regardless of hardware

<p>(The following is a rewording of the above required table):</p>
<p>The HAL must include sensor maximum resolution (defined by
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>).<wbr/></p>
<p>For FULL capability devices (<code><a href="#static_android.info.supportedHardwareLevel">android.<wbr/>info.<wbr/>supported<wbr/>Hardware<wbr/>Level</a> == FULL</code>),<wbr/>
the HAL must include all YUV_<wbr/>420_<wbr/>888 sizes that have JPEG sizes listed
here as output streams.<wbr/></p>
<p>It must also include each below resolution if it is smaller than or
equal to the sensor maximum resolution (for both YUV_<wbr/>420_<wbr/>888 and JPEG
formats),<wbr/> as output streams:</p>
<ul>
<li>240p (320 x 240)</li>
<li>480p (640 x 480)</li>
<li>720p (1280 x 720)</li>
<li>1080p (1920 x 1080)</li>
</ul>
<p>Note that for Performance Class 12 or higher primary cameras (first rear/<wbr/>front facing
camera in the camera ID list),<wbr/> camera framework filters out JPEG sizes smaller than
1080p depending on applications' targetSdkLevel.<wbr/> The camera HAL must still support the
smaller JPEG sizes to maintain backward comopatibility.<wbr/></p>
<p>For LIMITED capability devices
(<code><a href="#static_android.info.supportedHardwareLevel">android.<wbr/>info.<wbr/>supported<wbr/>Hardware<wbr/>Level</a> == LIMITED</code>),<wbr/>
the HAL only has to list up to the maximum video size
supported by the device.<wbr/></p>
<p>Regardless of hardware level,<wbr/> every output resolution available for
YUV_<wbr/>420_<wbr/>888 must also be available for IMPLEMENTATION_<wbr/>DEFINED.<wbr/></p>

<p>For devices not supporting <a href="#controls_android.distortionCorrection.mode">android.<wbr/>distortion<wbr/>Correction.<wbr/>mode</a> control,<wbr/> the coordinate

<p>For devices supporting <a href="#controls_android.distortionCorrection.mode">android.<wbr/>distortion<wbr/>Correction.<wbr/>mode</a> control,<wbr/> the coordinate system
depends on the mode being set.<wbr/> When the distortion correction mode is OFF,<wbr/> the
coordinate system follows <a href="#static_android.sensor.info.preCorrectionActiveArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>pre<wbr/>Correction<wbr/>Active<wbr/>Array<wbr/>Size</a>,<wbr/> with <code>(0,<wbr/>

<p>Output streams use this rectangle to produce their output,<wbr/> cropping to a smaller region
if necessary to maintain the stream's aspect ratio,<wbr/> then scaling the sensor input to
match the output's configured resolution.<wbr/></p>
<p>The crop region is applied after the RAW to other color space (e.<wbr/>g.<wbr/> YUV)
conversion.<wbr/> Since raw streams (e.<wbr/>g.<wbr/> RAW16) don't have the conversion stage,<wbr/> they are not
croppable.<wbr/> The crop region will be ignored by raw streams.<wbr/></p>
<p>For non-raw streams,<wbr/> any additional per-stream cropping will be done to maximize the
final pixel area of the stream.<wbr/></p>
<p>For example,<wbr/> if the crop region is set to a 4:3 aspect ratio,<wbr/> then 4:3 streams will use
the exact crop region.<wbr/> 16:9 streams will further crop vertically (letterbox).<wbr/></p>
<p>Conversely,<wbr/> if the crop region is set to a 16:9,<wbr/> then 4:3 outputs will crop horizontally
(pillarbox),<wbr/> and 16:9 streams will match exactly.<wbr/> These additional crops will be
centered within the crop region.<wbr/></p>
<p>To illustrate,<wbr/> here are several scenarios of different crop regions and output streams,<wbr/>
for a hypothetical camera device with an active array of size <code>(2000,<wbr/>1500)</code>.<wbr/> Note that
several of these examples use non-centered crop regions for ease of illustration; such
regions are only supported on devices with FREEFORM capability
(<a href="#static_android.scaler.croppingType">android.<wbr/>scaler.<wbr/>cropping<wbr/>Type</a> <code>== FREEFORM</code>),<wbr/> but this does not affect the way the crop

<p>The camera device may adjust the crop region to account for rounding and other hardware
requirements; the final crop region used will be included in the output capture result.<wbr/></p>
<p>The camera sensor output aspect ratio depends on factors such as output stream
combination and <a href="#controls_android.control.aeTargetFpsRange">android.<wbr/>control.<wbr/>ae<wbr/>Target<wbr/>Fps<wbr/>Range</a>,<wbr/> and shouldn't be adjusted by using
this control.<wbr/> And the camera device will treat different camera sensor output sizes
(potentially with in-sensor crop) as the same crop of
<a href="#static_android.sensor.info.activeArraySize">android.<wbr/>sensor.<wbr/>info.<wbr/>active<wbr/>Array<wbr/>Size</a>.<wbr/> As a result,<wbr/> the application shouldn't assume the
maximum crop region always maps to the same aspect ratio or field of view for the
sensor output.<wbr/></p>
<p>Starting from API level 30,<wbr/> it's strongly recommended to use <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a>
to take advantage of better support for zoom with logical multi-camera.<wbr/> The benefits
include better precision with optical-digital zoom combination,<wbr/> and ability to do
zoom-out from 1.<wbr/>0x.<wbr/> When using <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a> for zoom,<wbr/> the crop region in
the capture request should be left as the default activeArray size.<wbr/> The
coordinate system is post-zoom,<wbr/> meaning that the activeArraySize or
preCorrectionActiveArraySize covers the camera device's field of view "after" zoom.<wbr/> See

<p>This control is primarily intended to help camera applications with no support for
multi-window modes to work correctly on devices where multi-window scenarios are
unavoidable,<wbr/> such as foldables or other devices with variable display geometry or more
free-form window placement (such as laptops,<wbr/> which often place portrait-orientation apps
in landscape with pillarboxing).<wbr/></p>
<p>If supported,<wbr/> the default value is <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>AUTO</code>,<wbr/> which allows the camera API
to enable backwards-compatibility support for applications that do not support resizing
/<wbr/> multi-window modes,<wbr/> when the device is in fact in a multi-window mode (such as inset
portrait on laptops,<wbr/> or on a foldable device in some fold states).<wbr/> In addition,<wbr/>
<code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>NONE</code> and <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>90</code> will always be available if this control
is supported by the device.<wbr/> If not supported,<wbr/> devices API level 30 or higher will always
list only <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>NONE</code>.<wbr/></p>
<p>When <code>CROP_<wbr/>AUTO</code> is in use,<wbr/> and the camera API activates backward-compatibility mode,<wbr/>
several metadata fields will also be parsed differently to ensure that coordinates are
correctly handled for features like drawing face detection boxes or passing in
tap-to-focus coordinates.<wbr/> The camera API will convert positions in the active array
coordinate system to/<wbr/>from the cropped-and-rotated coordinate system to make the
operation transparent for applications.<wbr/> The following controls are affected:</p>
<ul>

<li><a href="#controls_android.control.afRegions">android.<wbr/>control.<wbr/>af<wbr/>Regions</a></li>

<li><a href="#dynamic_android.statistics.faces">android.<wbr/>statistics.<wbr/>faces</a></li>
</ul>
<p>Capture results will contain the actual value selected by the API;
<code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>AUTO</code> will never be seen in a capture result.<wbr/></p>
<p>Applications can also select their preferred cropping mode,<wbr/> either to opt out of the
backwards-compatibility treatment,<wbr/> or to use the cropping feature themselves as needed.<wbr/>
In this case,<wbr/> no coordinate translation will be done automatically,<wbr/> and all controls
will continue to use the normal active array coordinates.<wbr/></p>
<p>Cropping and rotating is done after the application of digital zoom (via either
<a href="#controls_android.scaler.cropRegion">android.<wbr/>scaler.<wbr/>crop<wbr/>Region</a> or <a href="#controls_android.control.zoomRatio">android.<wbr/>control.<wbr/>zoom<wbr/>Ratio</a>),<wbr/> but before each individual
output is further cropped and scaled.<wbr/> It only affects processed outputs such as
YUV,<wbr/> PRIVATE,<wbr/> and JPEG.<wbr/> It has no effect on RAW outputs.<wbr/></p>
<p>When <code>CROP_<wbr/>90</code> or <code>CROP_<wbr/>270</code> are selected,<wbr/> there is a significant loss to the field of
view.<wbr/> For example,<wbr/> with a 4:3 aspect ratio output of 1600x1200,<wbr/> <code>CROP_<wbr/>90</code> will still
produce 1600x1200 output,<wbr/> but these buffers are cropped from a vertical 3:4 slice at the
center of the 4:3 area,<wbr/> then rotated to be 4:3,<wbr/> and then upscaled to 1600x1200.<wbr/> Only
56.<wbr/>25% of the original FOV is still visible.<wbr/> In general,<wbr/> for an aspect ratio of <code>w:h</code>,<wbr/>
the crop and rotate operation leaves <code>(h/<wbr/>w)^2</code> of the field of view visible.<wbr/> For 16:9,<wbr/>
this is ~31.<wbr/>6%.<wbr/></p>
<p>As a visual example,<wbr/> the figure below shows the effect of <code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>90</code> on the
outputs for the following parameters:</p>
<ul>
<li>Sensor active array: <code>2000x1500</code></li>
<li>Crop region: top-left: <code>(500,<wbr/> 375)</code>,<wbr/> size: <code>(1000,<wbr/> 750)</code> (4:3 aspect ratio)</li>
<li>Output streams: YUV <code>640x480</code> and YUV <code>1280x720</code></li>
<li><code>ROTATE_<wbr/>AND_<wbr/>CROP_<wbr/>90</code></li>
</ul>

<p>With these settings,<wbr/> the regions of the active array covered by the output streams are:</p>

<p>The maximum frame rate that can be supported by a camera subsystem is
a function of many factors:</p>
<ul>
<li>Requested resolutions of output image streams</li>
<li>Availability of binning /<wbr/> skipping modes on the imager</li>
<li>The bandwidth of the imager interface</li>
<li>The bandwidth of the various ISP processing blocks</li>
</ul>
<p>Since these factors can vary greatly between different ISPs and
sensors,<wbr/> the camera abstraction tries to represent the bandwidth
restrictions with as simple a model as possible.<wbr/></p>
<p>The model presented has the following characteristics:</p>
<ul>
<li>The image sensor is always configured to output the smallest
resolution possible given the application's requested output stream
sizes.<wbr/> The smallest resolution is defined as being at least as large
as the largest requested output stream size; the camera pipeline must
never digitally upsample sensor data when the crop region covers the
whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
resolutions are configured,<wbr/> the sensor can provide a higher frame
rate.<wbr/></li>
<li>Since any request may use any or all the currently configured
output streams,<wbr/> the sensor and ISP must be configured to support
scaling a single capture to all the streams at the same time.<wbr/> This
means the camera pipeline must be ready to produce the largest
requested output size without any delay.<wbr/> Therefore,<wbr/> the overall
frame rate of a given configured stream set is governed only by the
largest requested stream resolution.<wbr/></li>
<li>Using more than one output stream in a request does not affect the
frame duration.<wbr/></li>
<li>Certain format-streams may need to do additional background processing
before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
can run concurrently to the rest of the camera pipeline,<wbr/> but
cannot process more than 1 capture at a time.<wbr/></li>
</ul>
<p>The necessary information for the application,<wbr/> given the model above,<wbr/> is provided via
<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
These are used to determine the maximum frame rate /<wbr/> minimum frame duration that is
possible for a given stream configuration.<wbr/></p>
<p>Specifically,<wbr/> the application can use the following rules to
determine the minimum frame duration it can request from the camera
device:</p>
<ol>
<li>Let the set of currently configured input/<wbr/>output streams be called <code>S</code>.<wbr/></li>
<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking it up in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be called <code>F</code>.<wbr/></li>
<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed for <code>R</code> is the maximum
out of all values in <code>F</code>.<wbr/> Let the streams used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
</ol>
<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code> determines the steady
state frame rate that the application will get if it uses <code>R</code> as a repeating request.<wbr/> Let
this special kind of request be called <code>Rsimple</code>.<wbr/></p>
<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved by a single capture of a
new request <code>Rstall</code> (which has at least one in-use stream with a non-0 stall time) and if
<code>Rstall</code> has the same minimum frame duration this will not cause a frame rate loss if all
buffers from the previous <code>Rstall</code> have already been delivered.<wbr/></p>
<p>For more details about stalling,<wbr/> see <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>.<wbr/></p>

<p>The maximum frame rate that can be supported by a camera subsystem is
a function of many factors:</p>
<ul>
<li>Requested resolutions of output image streams</li>
<li>Availability of binning /<wbr/> skipping modes on the imager</li>
<li>The bandwidth of the imager interface</li>
<li>The bandwidth of the various ISP processing blocks</li>
</ul>
<p>Since these factors can vary greatly between different ISPs and
sensors,<wbr/> the camera abstraction tries to represent the bandwidth
restrictions with as simple a model as possible.<wbr/></p>
<p>The model presented has the following characteristics:</p>
<ul>
<li>The image sensor is always configured to output the smallest
resolution possible given the application's requested output stream
sizes.<wbr/> The smallest resolution is defined as being at least as large
as the largest requested output stream size; the camera pipeline must
never digitally upsample sensor data when the crop region covers the
whole sensor.<wbr/> In general,<wbr/> this means that if only small output stream
resolutions are configured,<wbr/> the sensor can provide a higher frame
rate.<wbr/></li>
<li>Since any request may use any or all the currently configured
output streams,<wbr/> the sensor and ISP must be configured to support
scaling a single capture to all the streams at the same time.<wbr/> This
means the camera pipeline must be ready to produce the largest
requested output size without any delay.<wbr/> Therefore,<wbr/> the overall
frame rate of a given configured stream set is governed only by the
largest requested stream resolution.<wbr/></li>
<li>Using more than one output stream in a request does not affect the
frame duration.<wbr/></li>
<li>Certain format-streams may need to do additional background processing
before data is consumed/<wbr/>produced by that stream.<wbr/> These processors
can run concurrently to the rest of the camera pipeline,<wbr/> but
cannot process more than 1 capture at a time.<wbr/></li>
</ul>
<p>The necessary information for the application,<wbr/> given the model above,<wbr/> is provided via
<a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>.<wbr/>
These are used to determine the maximum frame rate /<wbr/> minimum frame duration that is
possible for a given stream configuration.<wbr/></p>
<p>Specifically,<wbr/> the application can use the following rules to
determine the minimum frame duration it can request from the camera
device:</p>
<ol>
<li>Let the set of currently configured input/<wbr/>output streams be called <code>S</code>.<wbr/></li>
<li>Find the minimum frame durations for each stream in <code>S</code>,<wbr/> by looking it up in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputMinFrameDuration">StreamConfigurationMap#getOutputMinFrameDuration</a>
(with its respective size/<wbr/>format).<wbr/> Let this set of frame durations be called <code>F</code>.<wbr/></li>
<li>For any given request <code>R</code>,<wbr/> the minimum frame duration allowed for <code>R</code> is the maximum
out of all values in <code>F</code>.<wbr/> Let the streams used in <code>R</code> be called <code>S_<wbr/>r</code>.<wbr/></li>
</ol>
<p>If none of the streams in <code>S_<wbr/>r</code> have a stall time (listed in <a href="https://developer.android.com/reference/android/hardware/camera2/params/StreamConfigurationMap.html#getOutputStallDuration">StreamConfigurationMap#getOutputStallDuration</a>
using its respective size/<wbr/>format),<wbr/> then the frame duration in <code>F</code> determines the steady
state frame rate that the application will get if it uses <code>R</code> as a repeating request.<wbr/> Let
this special kind of request be called <code>Rsimple</code>.<wbr/></p>
<p>A repeating request <code>Rsimple</code> can be <em>occasionally</em> interleaved by a single capture of a
new request <code>Rstall</code> (which has at least one in-use stream with a non-0 stall time) and if
<code>Rstall</code> has the same minimum frame duration this will not cause a frame rate loss if all
buffers from the previous <code>Rstall</code> have already been delivered.<wbr/></p>

<p>This value is an estimate of the worst case split between the

<p>The green split is calculated as follows:</p>
<ol>
<li>A 5x5 pixel (or larger) window W within the active sensor array is
chosen.<wbr/> The term 'pixel' here is taken to mean a group of 4 Bayer
mosaic channels (R,<wbr/> Gr,<wbr/> Gb,<wbr/> B).<wbr/> The location and size of the window
chosen is implementation defined,<wbr/> and should be chosen to provide a
green split estimate that is both representative of the entire image
for this camera sensor,<wbr/> and can be calculated quickly.<wbr/></li>
<li>The arithmetic mean of the green channels from the red
rows (mean_<wbr/>Gr) within W is computed.<wbr/></li>
<li>The arithmetic mean of the green channels from the blue
rows (mean_<wbr/>Gb) within W is computed.<wbr/></li>
<li>The maximum ratio R of the two means is computed as follows:

<p>The ratio R is the green split divergence reported for this property,<wbr/>
which represents how much the green channels differ in the mosaic
pattern.<wbr/> This value is typically used to determine the treatment of
the green mosaic channels when demosaicing.<wbr/></p>
<p>The green split value can be roughly interpreted as follows:</p>
<ul>
<li>R &lt; 1.<wbr/>03 is a negligible split (&lt;3% divergence).<wbr/></li>
<li>1.<wbr/>20 &lt;= R &gt;= 1.<wbr/>03 will require some software
correction to avoid demosaic errors (3-20% divergence).<wbr/></li>

<p>Since optical image stabilization generally involves motion much faster than the duration
of individual image exposure,<wbr/> multiple OIS samples can be included for a single capture
result.<wbr/> For example,<wbr/> if the OIS reporting operates at 200 Hz,<wbr/> a typical camera operating
at 30fps may have 6-7 OIS samples per capture result.<wbr/> This information can be combined
with the rolling shutter skew to account for lens motion during image exposure in
post-processing algorithms.<wbr/></p>

<p>Each OIS sample contains the timestamp and the amount of shifts in x and y direction,<wbr/>

<p>A positive value for a shift in x direction is a shift from left to right in the
pre-correction active array coordinate system.<wbr/> For example,<wbr/> if the optical center is
(1000,<wbr/> 500) in pre-correction active array coordinates,<wbr/> a shift of (3,<wbr/> 0) puts the new
optical center at (1003,<wbr/> 500).<wbr/></p>
<p>A positive value for a shift in y direction is a shift from top to bottom in
pre-correction active array coordinate system.<wbr/> For example,<wbr/> if the optical center is
(1000,<wbr/> 500) in active array coordinates,<wbr/> a shift of (0,<wbr/> 5) puts the new optical center at
(1000,<wbr/> 505).<wbr/></p>
<p>The OIS samples are not affected by whether lens distortion correction is enabled (on
supporting devices).<wbr/> They are always reported in pre-correction active array coordinates,<wbr/>
since the scaling of OIS shifts would depend on the specific spot on the sensor the shift
is needed.<wbr/></p>

<p>When set to <code>true</code> (ON),<wbr/> the values used for black-level
compensation will not change until the lock is set to

<p>Since changes to certain capture parameters (such as
exposure time) may require resetting of black level
compensation,<wbr/> the camera device must report whether setting
the black level lock was successful in the output result
metadata.<wbr/></p>
<p>For example,<wbr/> if a sequence of requests is as follows:</p>
<ul>
<li>Request 1: Exposure = 10ms,<wbr/> Black level lock = OFF</li>
<li>Request 2: Exposure = 10ms,<wbr/> Black level lock = ON</li>
<li>Request 3: Exposure = 10ms,<wbr/> Black level lock = ON</li>
<li>Request 4: Exposure = 20ms,<wbr/> Black level lock = ON</li>
<li>Request 5: Exposure = 20ms,<wbr/> Black level lock = ON</li>
<li>Request 6: Exposure = 20ms,<wbr/> Black level lock = ON</li>
</ul>
<p>And the exposure change in Request 4 requires the camera
device to reset the black level offsets,<wbr/> then the output
result metadata is expected to be:</p>
<ul>
<li>Result 1: Exposure = 10ms,<wbr/> Black level lock = OFF</li>
<li>Result 2: Exposure = 10ms,<wbr/> Black level lock = ON</li>
<li>Result 3: Exposure = 10ms,<wbr/> Black level lock = ON</li>
<li>Result 4: Exposure = 20ms,<wbr/> Black level lock = OFF</li>
<li>Result 5: Exposure = 20ms,<wbr/> Black level lock = ON</li>
<li>Result 6: Exposure = 20ms,<wbr/> Black level lock = ON</li>
</ul>
<p>This indicates to the application that on frame 4,<wbr/> black
levels were reset due to exposure value changes,<wbr/> and pixel
values may not be consistent across captures.<wbr/></p>
<p>The camera device will maintain the lock to the extent
possible,<wbr/> only overriding the lock to OFF when changes to
other request parameters require a black level recalculation
or reset.<wbr/></p>

each JPEG stream with HEIC stream in all guaranteed combinations.<wbr/></p>
<p>For every HEIC stream configured by the application,<wbr/> the camera framework sets up 2
internal streams with camera HAL:</p>
<ul>
<li>A YUV_<wbr/>420_<wbr/>888 or IMPLEMENTATION_<wbr/>DEFINED HAL stream as input to HEIC or HEVC encoder.<wbr/></li>
<li>A BLOB stream with JPEG_<wbr/>APPS_<wbr/>SEGMENTS dataspace to extract application markers
including EXIF and thumbnail to be saved in HEIF container.<wbr/></li>
</ul>
<p>A camera device can output HEIC format to the application if and only if:</p>
<ul>
<li>The system contains a HEIC or HEVC encoder with constant quality mode,<wbr/> and</li>
<li>This tag is set to TRUE,<wbr/> meaning that camera HAL supports replacing JPEG streams in
all mandatory stream combinations with a [YUV_<wbr/>420_<wbr/>888/<wbr/>IMPLEMENTATION_<wbr/>DEFINED stream +
JPEG_<wbr/>APPS_<wbr/>SEGMENT BLOB stream] combo.<wbr/></li>
</ul>
<p>As an example,<wbr/> if the camera device's hardware level is LIMITED,<wbr/> and it supports HEIC,<wbr/>
in addition to the required stream combinations,<wbr/> HAL must support below stream
combinations as well:</p>
<ul>
<li>IMPLEMENTATION_<wbr/>DEFINED/<wbr/>YUV_<wbr/>420_<wbr/>888 MAXIMUM + JPEG_<wbr/>SEGMENTS_<wbr/>BLOB,<wbr/></li>
<li>PRIV PREVIEW + IMPLEMENTATION_<wbr/>DEFINED/<wbr/>YUV_<wbr/>420_<wbr/>888 MAXIMUM + JPEG_<wbr/>SEGMENTS_<wbr/>BLOB,<wbr/></li>
<li>YUV PREVIEW + IMPLEMENTATION_<wbr/>DEFINED/<wbr/>YUV_<wbr/>420_<wbr/>888 MAXIMUM + JPEG_<wbr/>SEGMENTS_<wbr/>BLOB,<wbr/></li>
<li>PRIV PREVIEW + YUV PREVIEW + IMPLEMENTATION_<wbr/>DEFINED/<wbr/>YUV_<wbr/>420_<wbr/>888 MAXIMUM +
JPEG_<wbr/>SEGMENTS_<wbr/>BLOB</li>
</ul>
<p>The selection logic between YUV_<wbr/>420_<wbr/>888 and IMPLEMENTATION_<wbr/>DEFINED for HAL internal
stream is as follows:</p>
<pre><code>if (HEIC encoder exists and supports the size) {
use IMPLEMENTATION_<wbr/>DEFINED with GRALLOC_<wbr/>USAGE_<wbr/>HW_<wbr/>IMAGE_<wbr/>ENCODER usage flag;
} else {
//<wbr/> HVC encoder exists
if (size is less than framework predefined tile size) {
use IMPLEMENTATINO_<wbr/>DEFINED with GRALLOC_<wbr/>USAGE_<wbr/>HW_<wbr/>VIDEO_<wbr/>ENCODER usage flag;
} else {
use YUV_<wbr/>420_<wbr/>888;
}
}
</code></pre>
