The application-selected CaptureRequest#SENSOR_EXPOSURE_TIME, CaptureRequest#SENSOR_SENSITIVITY and CaptureRequest#SENSOR_FRAME_DURATION are used by the camera device, along with android.flash.* fields, if there's a flash unit for this camera device.

Note that auto-white balance (AWB) and auto-focus (AF) behavior is device dependent when AE is in OFF mode. To have consistent behavior across different devices, it is recommended to either set AWB and AF to OFF mode or lock AWB and AF before setting AE to OFF. See CaptureRequest#CONTROL_AWB_MODE, CaptureRequest#CONTROL_AF_MODE, CaptureRequest#CONTROL_AWB_LOCK, and CaptureRequest#CONTROL_AF_TRIGGER for more details.

CONTROL_AF_MODE_AUTO

public static final int CONTROL_AF_MODE_AUTO

Basic automatic focus mode.

In this mode, the lens does not move unless the autofocus trigger action is called. When that trigger is activated, AF will transition to ACTIVE_SCAN, then to the outcome of the scan (FOCUSED or NOT_FOCUSED).

Always supported if lens is not fixed focus.

Use CameraCharacteristics#LENS_INFO_MINIMUM_FOCUS_DISTANCE to determine if lens is fixed-focus.

Triggering AF_CANCEL resets the lens position to default, and sets the AF state to INACTIVE.

See also:

Constant Value: 1 (0x00000001)

CONTROL_AF_MODE_CONTINUOUS_PICTURE

public static final int CONTROL_AF_MODE_CONTINUOUS_PICTURE

In this mode, the AF algorithm modifies the lens position continually to attempt to provide a constantly-in-focus image stream.

The focusing behavior should be suitable for still image capture; typically this means focusing as fast as possible. When the AF trigger is not involved, the AF algorithm should start in INACTIVE state, and then transition into PASSIVE_SCAN and PASSIVE_FOCUSED states as appropriate as it attempts to maintain focus. When the AF trigger is activated, the algorithm should finish its PASSIVE_SCAN if active, and then transition into AF_FOCUSED or AF_NOT_FOCUSED as appropriate, and lock the lens position until a cancel AF trigger is received.

When the AF cancel trigger is activated, the algorithm should transition back to INACTIVE and then act as if it has just been started.

See also:

CaptureRequest.CONTROL_AF_MODE

Constant Value: 4 (0x00000004)

CONTROL_AF_MODE_CONTINUOUS_VIDEO

public static final int CONTROL_AF_MODE_CONTINUOUS_VIDEO

In this mode, the AF algorithm modifies the lens position continually to attempt to provide a constantly-in-focus image stream.

The focusing behavior should be suitable for good quality video recording; typically this means slower focus movement and no overshoots. When the AF trigger is not involved, the AF algorithm should start in INACTIVE state, and then transition into PASSIVE_SCAN and PASSIVE_FOCUSED states as appropriate. When the AF trigger is activated, the algorithm should immediately transition into AF_FOCUSED or AF_NOT_FOCUSED as appropriate, and lock the lens position until a cancel AF trigger is received.

Once cancel is received, the algorithm should transition back to INACTIVE and resume passive scan. Note that this behavior is not identical to CONTINUOUS_PICTURE, since an ongoing PASSIVE_SCAN must immediately be canceled.

All control by the device's metering and focusing (3A) routines is disabled, and no other settings in android.control.* have any effect, except that CaptureRequest#CONTROL_CAPTURE_INTENT may be used by the camera device to select post-processing values for processing blocks that do not allow for manual control, or are not exposed by the camera API.

However, the camera device's 3A routines may continue to collect statistics and update their internal state so that when control is switched to AUTO mode, good control values can be immediately applied.

Constant Value: 0 (0x00000000)

CONTROL_MODE_OFF_KEEP_STATE

public static final int CONTROL_MODE_OFF_KEEP_STATE

Same as OFF mode, except that this capture will not be used by camera device background auto-exposure, auto-white balance and auto-focus algorithms (3A) to update their statistics.

Specifically, the 3A routines are locked to the last values set from a request with AUTO, OFF, or USE_SCENE_MODE, and any statistics or state updates collected from manual captures with OFF_KEEP_STATE will be discarded by the camera device.

CONTROL_MODE_USE_EXTENDED_SCENE_MODE

public static final int CONTROL_MODE_USE_EXTENDED_SCENE_MODE

Use a specific extended scene mode.

When extended scene mode is on, the camera device may override certain control parameters, such as targetFpsRange, AE, AWB, and AF modes, to achieve best power and quality tradeoffs. Only the mandatory stream combinations of LIMITED hardware level are guaranteed.

This setting can only be used if extended scene mode is supported (i.e. android.control.availableExtendedSceneModes contains some modes other than DISABLED).

Constant Value: 4 (0x00000004)

CONTROL_MODE_USE_SCENE_MODE

public static final int CONTROL_MODE_USE_SCENE_MODE

Use a specific scene mode.

Enabling this disables control.aeMode, control.awbMode and control.afMode controls; the camera device will ignore those settings while USE_SCENE_MODE is active (except for FACE_PRIORITY scene mode). Other control entries are still active. This setting can only be used if scene mode is supported (i.e. CameraCharacteristics#CONTROL_AVAILABLE_SCENE_MODES contain some modes other than DISABLED).

For extended scene modes such as BOKEH, please use USE_EXTENDED_SCENE_MODE instead.

If face detection statistics are disabled (i.e. CaptureRequest#STATISTICS_FACE_DETECT_MODE is set to OFF), this should still operate correctly (but will not return face detection statistics to the framework).

Unlike the other scene modes, CaptureRequest#CONTROL_AE_MODE, CaptureRequest#CONTROL_AWB_MODE, and CaptureRequest#CONTROL_AF_MODE remain active when FACE_PRIORITY is set.

CONTROL_SCENE_MODE_HDR

public static final int CONTROL_SCENE_MODE_HDR

Turn on a device-specific high dynamic range (HDR) mode.

In this scene mode, the camera device captures images that keep a larger range of scene illumination levels visible in the final image. For example, when taking a picture of a object in front of a bright window, both the object and the scene through the window may be visible when using HDR mode, while in normal AUTO mode, one or the other may be poorly exposed. As a tradeoff, HDR mode generally takes much longer to capture a single image, has no user control, and may have other artifacts depending on the HDR method used.

Therefore, HDR captures operate at a much slower rate than regular captures.

In this mode, on LIMITED or FULL devices, when a request is made with a CaptureRequest#CONTROL_CAPTURE_INTENT of STILL_CAPTURE, the camera device will capture an image using a high dynamic range capture technique. On LEGACY devices, captures that target a JPEG-format output will be captured with HDR, and the capture intent is not relevant.

The HDR capture may involve the device capturing a burst of images internally and combining them into one, or it may involve the device using specialized high dynamic range capture hardware. In all cases, a single image is produced in response to a capture request submitted while in HDR mode.

Since substantial post-processing is generally needed to produce an HDR image, only YUV, PRIVATE, and JPEG outputs are supported for LIMITED/FULL device HDR captures, and only JPEG outputs are supported for LEGACY HDR captures. Using a RAW output for HDR capture is not supported.

Some devices may also support always-on HDR, which applies HDR processing at full frame rate. For these devices, intents other than STILL_CAPTURE will also produce an HDR output with no frame rate impact compared to normal operation, though the quality may be lower than for STILL_CAPTURE intents.

If SCENE_MODE_HDR is used with unsupported output types or capture intents, the images captured will be as if the SCENE_MODE was not enabled at all.

CONTROL_SCENE_MODE_HIGH_SPEED_VIDEO

public static final int CONTROL_SCENE_MODE_HIGH_SPEED_VIDEO

This constant is deprecated.
Please refer to this API documentation to find the alternatives

This is deprecated, please use CameraDevice.createConstrainedHighSpeedCaptureSession(List, CameraCaptureSession.StateCallback, Handler) and CameraConstrainedHighSpeedCaptureSession.createHighSpeedRequestList(CaptureRequest) for high speed video recording.

Optimized for high speed video recording (frame rate >=60fps) use case.

The supported high speed video sizes and fps ranges are specified in android.control.availableHighSpeedVideoConfigurations. To get desired output frame rates, the application is only allowed to select video size and fps range combinations listed in this static metadata. The fps range can be control via CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE.

In this mode, the camera device will override aeMode, awbMode, and afMode to ON, ON, and CONTINUOUS_VIDEO, respectively. All post-processing block mode controls will be overridden to be FAST. Therefore, no manual control of capture and post-processing parameters is possible. All other controls operate the same as when CaptureRequest#CONTROL_MODE == AUTO. This means that all other android.control.* fields continue to work, such as

Outside of android.control.*, the following controls will work:

CaptureRequest#FLASH_MODE (automatic flash for still capture will not work since aeMode is ON)
CaptureRequest#LENS_OPTICAL_STABILIZATION_MODE (if it is supported)
CaptureRequest#SCALER_CROP_REGION
CaptureRequest#STATISTICS_FACE_DETECT_MODE

For high speed recording use case, the actual maximum supported frame rate may be lower than what camera can output, depending on the destination Surfaces for the image data. For example, if the destination surface is from video encoder, the application need check if the video encoder is capable of supporting the high frame rate for a given video size, or it will end up with lower recording frame rate. If the destination surface is from preview window, the preview frame rate will be bounded by the screen refresh rate.

The camera device will only support up to 2 output high speed streams (processed non-stalling format defined in android.request.maxNumOutputStreams) in this mode. This control will be effective only if all of below conditions are true:

The application created no more than maxNumHighSpeedStreams processed non-stalling format output streams, where maxNumHighSpeedStreams is calculated as min(2, android.request.maxNumOutputStreams[Processed (but not-stalling)]).
The stream sizes are selected from the sizes reported by android.control.availableHighSpeedVideoConfigurations.
No processed non-stalling or raw streams are configured.

When above conditions are NOT satistied, the controls of this mode and CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE will be ignored by the camera device, the camera device will fall back to CaptureRequest#CONTROL_MODE == AUTO, and the returned capture result metadata will give the fps range choosen by the camera device.

Switching into or out of this mode may trigger some camera ISP/sensor reconfigurations, which may introduce extra latency. It is recommended that the application avoids unnecessary scene mode switch as much as possible.

Constant Value: 0 (0x00000000)

EDGE_MODE_ZERO_SHUTTER_LAG

public static final int EDGE_MODE_ZERO_SHUTTER_LAG

Edge enhancement is applied at different levels for different output streams, based on resolution. Streams at maximum recording resolution (see CameraDevice.createCaptureSession(SessionConfiguration)) or below have edge enhancement applied, while higher-resolution streams have no edge enhancement applied. The level of edge enhancement for low-resolution streams is tuned so that frame rate is not impacted, and the quality is equal to or better than FAST (since it is only applied to lower-resolution outputs, quality may improve from FAST).

This mode is intended to be used by applications operating in a zero-shutter-lag mode with YUV or PRIVATE reprocessing, where the application continuously captures high-resolution intermediate buffers into a circular buffer, from which a final image is produced via reprocessing when a user takes a picture. For such a use case, the high-resolution buffers must not have edge enhancement applied to maximize efficiency of preview and to avoid double-applying enhancement when reprocessed, while low-resolution buffers (used for recording or preview, generally) need edge enhancement applied for reasonable preview quality.

This mode is guaranteed to be supported by devices that support either the YUV_REPROCESSING or PRIVATE_REPROCESSING capabilities (CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES lists either of those capabilities) and it will be the default mode for CAMERA3_TEMPLATE_ZERO_SHUTTER_LAG template.

This camera device is backed by an external camera connected to this Android device.

The device has capability identical to a LIMITED level device, with the following exceptions:

The device may not report lens/sensor related information such as
The device will report 0 for CameraCharacteristics#SENSOR_ORIENTATION
The device has less guarantee on stable framerate, as the framerate partly depends on the external camera being used.

public static final int INFO_SUPPORTED_HARDWARE_LEVEL_FULL

This camera device is capable of supporting advanced imaging applications.

The stream configurations listed in the FULL, LEGACY and LIMITED tables in the createCaptureSession documentation are guaranteed to be supported.

A FULL device will support below capabilities:

BURST_CAPTURE capability (CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES contains BURST_CAPTURE)
Per frame control (CameraCharacteristics#SYNC_MAX_LATENCY == PER_FRAME_CONTROL)
Manual sensor control (CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES contains MANUAL_SENSOR)
Manual post-processing control (CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES contains MANUAL_POST_PROCESSING)
The required exposure time range defined in CameraCharacteristics#SENSOR_INFO_EXPOSURE_TIME_RANGE
The required maxFrameDuration defined in CameraCharacteristics#SENSOR_INFO_MAX_FRAME_DURATION

INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY

public static final int INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY

This camera device is running in backward compatibility mode.

Only the stream configurations listed in the LEGACY table in the createCaptureSession documentation are supported.

A LEGACY device does not support per-frame control, manual sensor control, manual post-processing, arbitrary cropping regions, and has relaxed performance constraints. No additional capabilities beyond BACKWARD_COMPATIBLE will ever be listed by a LEGACY device in CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES.

In addition, the CaptureRequest#CONTROL_AE_PRECAPTURE_TRIGGER is not functional on LEGACY devices. Instead, every request that includes a JPEG-format output target is treated as triggering a still capture, internally executing a precapture trigger. This may fire the flash for flash power metering during precapture, and then fire the flash for the final capture, if a flash is available on the device and the AE mode is set to enable the flash.

Devices that initially shipped with Android version Q or newer will not include any LEGACY-level devices.

Constant Value: 2 (0x00000002)

INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED

public static final int INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED

This camera device does not have enough capabilities to qualify as a FULL device or better.

Only the stream configurations listed in the LEGACY and LIMITED tables in the createCaptureSession documentation are guaranteed to be supported.

All LIMITED devices support the BACKWARDS_COMPATIBLE capability, indicating basic support for color image capture. The only exception is that the device may alternatively support only the DEPTH_OUTPUT capability, if it can only output depth measurements and not color images.

LIMITED devices and above require the use of CaptureRequest#CONTROL_AE_PRECAPTURE_TRIGGER to lock exposure metering (and calculate flash power, for cameras with flash) before capturing a high-quality still image.

A LIMITED device that only lists the BACKWARDS_COMPATIBLE capability is only required to support full-automatic operation and post-processing (OFF is not supported for CaptureRequest#CONTROL_AE_MODE, CaptureRequest#CONTROL_AF_MODE, or CaptureRequest#CONTROL_AWB_MODE)

Additional capabilities may optionally be supported by a LIMITED-level device, and can be checked for in CameraCharacteristics#REQUEST_AVAILABLE_CAPABILITIES.

Noise reduction is applied at different levels for different output streams, based on resolution. Streams at maximum recording resolution (see CameraDevice.createCaptureSession(SessionConfiguration)) or below have noise reduction applied, while higher-resolution streams have MINIMAL (if supported) or no noise reduction applied (if MINIMAL is not supported.) The degree of noise reduction for low-resolution streams is tuned so that frame rate is not impacted, and the quality is equal to or better than FAST (since it is only applied to lower-resolution outputs, quality may improve from FAST).

This mode is intended to be used by applications operating in a zero-shutter-lag mode with YUV or PRIVATE reprocessing, where the application continuously captures high-resolution intermediate buffers into a circular buffer, from which a final image is produced via reprocessing when a user takes a picture. For such a use case, the high-resolution buffers must not have noise reduction applied to maximize efficiency of preview and to avoid over-applying noise filtering when reprocessing, while low-resolution buffers (used for recording or preview, generally) need noise reduction applied for reasonable preview quality.

REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE

public static final int REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE

The minimal set of capabilities that every camera device (regardless of CameraCharacteristics#INFO_SUPPORTED_HARDWARE_LEVEL) supports.

This capability is listed by all normal devices, and indicates that the camera device has a feature set that's comparable to the baseline requirements for the older android.hardware.Camera API.

Devices with the DEPTH_OUTPUT capability might not list this capability, indicating that they support only depth measurement, not standard color output.

Constant Value: 0 (0x00000000)

REQUEST_AVAILABLE_CAPABILITIES_BURST_CAPTURE

public static final int REQUEST_AVAILABLE_CAPABILITIES_BURST_CAPTURE

The camera device supports capturing high-resolution images at >= 20 frames per second, in at least the uncompressed YUV format, when post-processing settings are set to FAST. Additionally, all image resolutions less than 24 megapixels can be captured at >= 10 frames per second. Here, 'high resolution' means at least 8 megapixels, or the maximum resolution of the device, whichever is smaller.

More specifically, this means that a size matching the camera device's active array size is listed as a supported size for the ImageFormat.YUV_420_888 format in either StreamConfigurationMap.getOutputSizes(int) or StreamConfigurationMap.getHighResolutionOutputSizes(int), with a minimum frame duration for that format and size of either <= 1/20 s, or <= 1/10 s if the image size is less than 24 megapixels, respectively; and the CameraCharacteristics#CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES entry lists at least one FPS range where the minimum FPS is >= 1 / minimumFrameDuration for the maximum-size YUV_420_888 format. If that maximum size is listed in StreamConfigurationMap.getHighResolutionOutputSizes(int), then the list of resolutions for YUV_420_888 from StreamConfigurationMap.getOutputSizes(int) contains at least one resolution >= 8 megapixels, with a minimum frame duration of <= 1/20 s.

If the device supports the ImageFormat.RAW10, ImageFormat.RAW12, ImageFormat.Y8, then those can also be captured at the same rate as the maximum-size YUV_420_888 resolution is.

If the device supports the PRIVATE_REPROCESSING capability, then the same guarantees as for the YUV_420_888 format also apply to the ImageFormat.PRIVATE format.

In addition, the CameraCharacteristics#SYNC_MAX_LATENCY field is guaranted to have a value between 0 and 4, inclusive. CameraCharacteristics#CONTROL_AE_LOCK_AVAILABLE and CameraCharacteristics#CONTROL_AWB_LOCK_AVAILABLE are also guaranteed to be true so burst capture with these two locks ON yields consistent image output.

Constant Value: 6 (0x00000006)

REQUEST_AVAILABLE_CAPABILITIES_CONSTRAINED_HIGH_SPEED_VIDEO

public static final int REQUEST_AVAILABLE_CAPABILITIES_CONSTRAINED_HIGH_SPEED_VIDEO

The device supports constrained high speed video recording (frame rate >=120fps) use case. The camera device will support high speed capture session created by CameraDevice.createConstrainedHighSpeedCaptureSession(List, CameraCaptureSession.StateCallback, Handler), which only accepts high speed request lists created by CameraConstrainedHighSpeedCaptureSession.createHighSpeedRequestList(CaptureRequest).

A camera device can still support high speed video streaming by advertising the high speed FPS ranges in CameraCharacteristics#CONTROL_AE_AVAILABLE_TARGET_FPS_RANGES. For this case, all normal capture request per frame control and synchronization requirements will apply to the high speed fps ranges, the same as all other fps ranges. This capability describes the capability of a specialized operating mode with many limitations (see below), which is only targeted at high speed video recording.

The supported high speed video sizes and fps ranges are specified in StreamConfigurationMap.getHighSpeedVideoFpsRanges(). To get desired output frame rates, the application is only allowed to select video size and FPS range combinations provided by StreamConfigurationMap.getHighSpeedVideoSizes(). The fps range can be controlled via CaptureRequest#CONTROL_AE_TARGET_FPS_RANGE.

In this capability, the camera device will override aeMode, awbMode, and afMode to ON, AUTO, and CONTINUOUS_VIDEO, respectively. All post-processing block mode controls will be overridden to be FAST. Therefore, no manual control of capture and post-processing parameters is possible. All other controls operate the same as when CaptureRequest#CONTROL_MODE == AUTO. This means that all other android.control.* fields continue to work, such as

Outside of android.control.*, the following controls will work:

CaptureRequest#FLASH_MODE (TORCH mode only, automatic flash for still capture will not work since aeMode is ON)
CaptureRequest#LENS_OPTICAL_STABILIZATION_MODE (if it is supported)
CaptureRequest#SCALER_CROP_REGION
CaptureRequest#STATISTICS_FACE_DETECT_MODE (if it is supported)

For high speed recording use case, the actual maximum supported frame rate may be lower than what camera can output, depending on the destination Surfaces for the image data. For example, if the destination surface is from video encoder, the application need check if the video encoder is capable of supporting the high frame rate for a given video size, or it will end up with lower recording frame rate. If the destination surface is from preview window, the actual preview frame rate will be bounded by the screen refresh rate.

The camera device will only support up to 2 high speed simultaneous output surfaces (preview and recording surfaces) in this mode. Above controls will be effective only if all of below conditions are true:

The application creates a camera capture session with no more than 2 surfaces via CameraDevice.createConstrainedHighSpeedCaptureSession(List, CameraCaptureSession.StateCallback, Handler). The targeted surfaces must be preview surface (either from SurfaceView or SurfaceTexture) or recording surface(either from MediaRecorder.getSurface() or MediaCodec.createInputSurface()).
The stream sizes are selected from the sizes reported by StreamConfigurationMap.getHighSpeedVideoSizes().
The FPS ranges are selected from StreamConfigurationMap.getHighSpeedVideoFpsRanges().

When above conditions are NOT satistied, CameraDevice.createConstrainedHighSpeedCaptureSession(List, CameraCaptureSession.StateCallback, Handler) will fail.

Switching to a FPS range that has different maximum FPS may trigger some camera device reconfigurations, which may introduce extra latency. It is recommended that the application avoids unnecessary maximum target FPS changes as much as possible during high speed streaming.

REQUEST_AVAILABLE_CAPABILITIES_DEPTH_OUTPUT

public static final int REQUEST_AVAILABLE_CAPABILITIES_DEPTH_OUTPUT

The camera device can produce depth measurements from its field of view.

This capability requires the camera device to support the following:

ImageFormat.DEPTH16 is supported as an output format.
ImageFormat.DEPTH_POINT_CLOUD is optionally supported as an output format.
This camera device, and all camera devices with the same CameraCharacteristics#LENS_FACING, will list the following calibration metadata entries in both CameraCharacteristics and CaptureResult:
The CameraCharacteristics#DEPTH_DEPTH_IS_EXCLUSIVE entry is listed by this device.
As of Android P, the CameraCharacteristics#LENS_POSE_REFERENCE entry is listed by this device.
A LIMITED camera with only the DEPTH_OUTPUT capability does not have to support normal YUV_420_888, Y8, JPEG, and PRIV-format outputs. It only has to support the DEPTH16 format.

Generally, depth output operates at a slower frame rate than standard color capture, so the DEPTH16 and DEPTH_POINT_CLOUD formats will commonly have a stall duration that should be accounted for (see StreamConfigurationMap.getOutputStallDuration(int, Size)). On a device that supports both depth and color-based output, to enable smooth preview, using a repeating burst is recommended, where a depth-output target is only included once every N frames, where N is the ratio between preview output rate and depth output rate, including depth stall time.

Constant Value: 8 (0x00000008)

REQUEST_AVAILABLE_CAPABILITIES_LOGICAL_MULTI_CAMERA

public static final int REQUEST_AVAILABLE_CAPABILITIES_LOGICAL_MULTI_CAMERA

The camera device is a logical camera backed by two or more physical cameras.

In API level 28, the physical cameras must also be exposed to the application via CameraManager.getCameraIdList().

Starting from API level 29:

Some or all physical cameras may not be independently exposed to the application, in which case the physical camera IDs will not be available in CameraManager.getCameraIdList(). But the application can still query the physical cameras' characteristics by calling CameraManager.getCameraCharacteristics(String).
If a physical camera is hidden from camera ID list, the mandatory stream combinations for that physical camera must be supported through the logical camera using physical streams. One exception is that in API level 30, a physical camera may become unavailable via CameraManager.AvailabilityCallback#onPhysicalCameraUnavailable callback.

Combinations of logical and physical streams, or physical streams from different physical cameras are not guaranteed. However, if the camera device supports CameraDevice#isSessionConfigurationSupported, application must be able to query whether a stream combination involving physical streams is supported by calling CameraDevice#isSessionConfigurationSupported.

Camera application shouldn't assume that there are at most 1 rear camera and 1 front camera in the system. For an application that switches between front and back cameras, the recommendation is to switch between the first rear camera and the first front camera in the list of supported camera devices.

This capability requires the camera device to support the following:

The IDs of underlying physical cameras are returned via CameraCharacteristics.getPhysicalCameraIds().
This camera device must list static metadata CameraCharacteristics#LOGICAL_MULTI_CAMERA_SENSOR_SYNC_TYPE in CameraCharacteristics.
The underlying physical cameras' static metadata must list the following entries, so that the application can correlate pixels from the physical streams:
The SENSOR_INFO_TIMESTAMP_SOURCE of the logical device and physical devices must be the same.
The logical camera must be LIMITED or higher device.

A logical camera device's dynamic metadata may contain CaptureResult#LOGICAL_MULTI_CAMERA_ACTIVE_PHYSICAL_ID to notify the application of the current active physical camera Id. An active physical camera is the physical camera from which the logical camera's main image data outputs (YUV or RAW) and metadata come from. In addition, this serves as an indication which physical camera is used to output to a RAW stream, or in case only physical cameras support RAW, which physical RAW stream the application should request.

Logical camera's static metadata tags below describe the default active physical camera. An active physical camera is default if it's used when application directly uses requests built from a template. All templates will default to the same active physical camera.

The field of view of non-RAW physical streams must not be smaller than that of the non-RAW logical streams, or the maximum field-of-view of the physical camera, whichever is smaller. The application should check the physical capture result metadata for how the physical streams are cropped or zoomed. More specifically, given the physical camera result metadata, the effective horizontal field-of-view of the physical camera is:

fov = 2 * atan2(cropW * sensorW / (2 * zoomRatio * activeArrayW), focalLength)

where the equation parameters are the physical camera's crop region width, physical sensor width, zoom ratio, active array width, and focal length respectively. Typically the physical stream of active physical camera has the same field-of-view as the logical streams. However, the same may not be true for physical streams from non-active physical cameras. For example, if the logical camera has a wide-ultrawide configuration where the wide lens is the default, when the crop region is set to the logical camera's active array size, (and the zoom ratio set to 1.0 starting from Android 11), a physical stream for the ultrawide camera may prefer outputing images with larger field-of-view than that of the wide camera for better stereo matching margin or more robust motion tracking. At the same time, the physical non-RAW streams' field of view must not be smaller than the requested crop region and zoom ratio, as long as it's within the physical lens' capability. For example, for a logical camera with wide-tele lens configuration where the wide lens is the default, if the logical camera's crop region is set to maximum size, and zoom ratio set to 1.0, the physical stream for the tele lens will be configured to its maximum size crop region (no zoom).

Deprecated: Prior to Android 11, the field of view of all non-RAW physical streams cannot be larger than that of non-RAW logical streams. If the logical camera has a wide-ultrawide lens configuration where the wide lens is the default, when the logical camera's crop region is set to maximum size, the FOV of the physical streams for the ultrawide lens will be the same as the logical stream, by making the crop region smaller than its active array size to compensate for the smaller focal length.

Even if the underlying physical cameras have different RAW characteristics (such as size or CFA pattern), a logical camera can still advertise RAW capability. In this case, when the application configures a RAW stream, the camera device will make sure the active physical camera will remain active to ensure consistent RAW output behavior, and not switch to other physical cameras.

The capture request and result metadata tags required for backward compatible camera functionalities will be solely based on the logical camera capabiltity. On the other hand, 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. For example, when the application manually sets exposure time and sensitivity while zooming in, the brightness of the camera images may suddenly change because HAL switches from one physical camera to the other.

REQUEST_AVAILABLE_CAPABILITIES_MANUAL_POST_PROCESSING

public static final int REQUEST_AVAILABLE_CAPABILITIES_MANUAL_POST_PROCESSING

The camera device post-processing stages can be manually controlled. The camera device supports basic manual control of the image post-processing stages. This means the following controls are guaranteed to be supported:

Manual tonemap control
Manual white balance control
- CaptureRequest#COLOR_CORRECTION_TRANSFORM
- CaptureRequest#COLOR_CORRECTION_GAINS
Manual lens shading map control
- CaptureRequest#SHADING_MODE
- CaptureRequest#STATISTICS_LENS_SHADING_MAP_MODE

- CaptureRequest#COLOR_CORRECTION_ABERRATION_MODE
- CameraCharacteristics#COLOR_CORRECTION_AVAILABLE_ABERRATION_MODES
Auto white balance lock
- CaptureRequest#CONTROL_AWB_LOCK

If auto white balance is enabled, then the camera device will accurately report the values applied by AWB in the result.

A given camera device may also support additional post-processing controls, but this capability only covers the above list of controls.

For camera devices with LOGICAL_MULTI_CAMERA capability, when underlying active physical camera switches, tonemap, white balance, and shading map may change even if awb is locked. However, the overall post-processing experience for users will be consistent. Refer to LOGICAL_MULTI_CAMERA capability for details.

REQUEST_AVAILABLE_CAPABILITIES_MANUAL_SENSOR

public static final int REQUEST_AVAILABLE_CAPABILITIES_MANUAL_SENSOR

The camera device can be manually controlled (3A algorithms such as auto-exposure, and auto-focus can be bypassed). The camera device supports basic manual control of the sensor image acquisition related stages. This means the following controls are guaranteed to be supported:

Manual frame duration control
- CaptureRequest#SENSOR_FRAME_DURATION
- CameraCharacteristics#SENSOR_INFO_MAX_FRAME_DURATION
Manual exposure control
- CaptureRequest#SENSOR_EXPOSURE_TIME
- CameraCharacteristics#SENSOR_INFO_EXPOSURE_TIME_RANGE
Manual sensitivity control
- CaptureRequest#SENSOR_SENSITIVITY
- CameraCharacteristics#SENSOR_INFO_SENSITIVITY_RANGE
Manual lens control (if the lens is adjustable)
- android.lens.*
Manual flash control (if a flash unit is present)
- android.flash.*
Manual black level locking
- CaptureRequest#BLACK_LEVEL_LOCK
Auto exposure lock
- CaptureRequest#CONTROL_AE_LOCK

If any of the above 3A algorithms are enabled, then the camera device will accurately report the values applied by 3A in the result.

A given camera device may also support additional manual sensor controls, but this capability only covers the above list of controls.

If this is supported, CameraCharacteristics#SCALER_STREAM_CONFIGURATION_MAP will additionally return a min frame duration that is greater than zero for each supported size-format combination.

For camera devices with LOGICAL_MULTI_CAMERA capability, when the underlying active physical camera switches, exposureTime, sensitivity, and lens properties may change even if AE/AF is locked. However, the overall auto exposure and auto focus experience for users will be consistent. Refer to LOGICAL_MULTI_CAMERA capability for details.

REQUEST_AVAILABLE_CAPABILITIES_MONOCHROME

public static final int REQUEST_AVAILABLE_CAPABILITIES_MONOCHROME

The camera device is a monochrome camera that doesn't contain a color filter array, and for YUV_420_888 stream, the pixel values on U and V planes are all 128.

A MONOCHROME camera must support the guaranteed stream combinations required for its device level and capabilities. Additionally, if the monochrome camera device supports Y8 format, all mandatory stream combination requirements related to YUV_420_888 apply to Y8 as well. There are no mandatory stream combination requirements with regard to Y8 for Bayer camera devices.

Starting from Android Q, the SENSOR_INFO_COLOR_FILTER_ARRANGEMENT of a MONOCHROME camera will be either MONO or NIR.

Constant Value: 10 (0x0000000a)

REQUEST_AVAILABLE_CAPABILITIES_OFFLINE_PROCESSING

public static final int REQUEST_AVAILABLE_CAPABILITIES_OFFLINE_PROCESSING

The camera device supports the OFFLINE_PROCESSING use case.

With OFFLINE_PROCESSING capability, the application can switch an ongoing capture session to offline mode by calling the CameraCaptureSession#switchToOffline method and specify streams to be kept in offline mode. The camera will then stop currently active repeating requests, prepare for some requests to go into offline mode, and return an offline session object. After the switchToOffline call returns, the original capture session is in closed state as if the CameraCaptureSession#close method has been called. In the offline mode, all inflight requests will continue to be processed in the background, and the application can immediately close the camera or create a new capture session without losing those requests' output images and capture results.

While the camera device is processing offline requests, it might not be able to support all stream configurations it can support without offline requests. When that happens, the createCaptureSession method call will fail. The following stream configurations are guaranteed to work without hitting the resource busy exception:

One ongoing offline session: target one output surface of YUV or JPEG format, any resolution.
The active camera capture session:
1. One preview surface (SurfaceView or SurfaceTexture) up to 1920 width
2. One YUV ImageReader surface up to 1920 width
3. One Jpeg ImageReader, any resolution: the camera device is allowed to slow down JPEG output speed by 50% if there is any ongoing offline session.
4. If the device supports PRIVATE_REPROCESSING, one pair of ImageWriter/ImageReader surfaces of private format, with the same resolution that is larger or equal to the JPEG ImageReader resolution above.
Alternatively, the active camera session above can be replaced by an legacy Camera with the following parameter settings:
1. Preview size up to 1920 width
2. Preview callback size up to 1920 width
3. Video size up to 1920 width
4. Picture size, any resolution: the camera device is allowed to slow down JPEG output speed by 50% if there is any ongoing offline session.

Using ImageFormat.PRIVATE does not cause a frame rate drop relative to the sensor's maximum capture rate (at that resolution).
ImageFormat.PRIVATE will be reprocessable into both ImageFormat.YUV_420_888 and ImageFormat.JPEG formats.
For a MONOCHROME camera supporting Y8 format, ImageFormat.PRIVATE will be reprocessable into ImageFormat.Y8.
The maximum available resolution for PRIVATE streams (both input/output) will match the maximum available resolution of JPEG streams.

REQUEST_AVAILABLE_CAPABILITIES_YUV_REPROCESSING

public static final int REQUEST_AVAILABLE_CAPABILITIES_YUV_REPROCESSING

The camera device supports the YUV_420_888 reprocessing use case, similar as PRIVATE_REPROCESSING, This capability requires the camera device to support the following:

One input stream is supported, that is, CameraCharacteristics#REQUEST_MAX_NUM_INPUT_STREAMS == 1.
ImageFormat.YUV_420_888 is supported as an output/input format, that is, YUV_420_888 is included in the lists of formats returned by StreamConfigurationMap.getInputFormats() and StreamConfigurationMap.getOutputFormats().
StreamConfigurationMap.getValidOutputFormatsForInput(int) returns non-empty int[] for each supported input format returned by StreamConfigurationMap.getInputFormats().
Each size returned by getInputSizes(YUV_420_888) is also included in getOutputSizes(YUV_420_888)
Using ImageFormat.YUV_420_888 does not cause a frame rate drop relative to the sensor's maximum capture rate (at that resolution).
ImageFormat.YUV_420_888 will be reprocessable into both ImageFormat.YUV_420_888 and ImageFormat.JPEG formats.
The maximum available resolution for ImageFormat.YUV_420_888 streams (both input/output) will match the maximum available resolution of ImageFormat.JPEG streams.

SENSOR_INFO_TIMESTAMP_SOURCE_REALTIME

public static final int SENSOR_INFO_TIMESTAMP_SOURCE_REALTIME

Timestamps from CaptureResult#SENSOR_TIMESTAMP are in the same timebase as SystemClock.elapsedRealtimeNanos(), and they can be compared to other timestamps using that base.

When buffers from a REALTIME device are passed directly to a video encoder from the camera, automatic compensation is done to account for differing timebases of the audio and camera subsystems. If the application is receiving buffers and then later sending them to a video encoder or other application where they are compared with audio subsystem timestamps or similar, this compensation is not present. In those cases, applications need to adjust the timestamps themselves. Since SystemClock.elapsedRealtimeNanos() and SystemClock.uptimeMillis() only diverge while the device is asleep, an offset between the two sources can be measured once per active session and applied to timestamps for sufficient accuracy for A/V sync.

Constant Value: 1 (0x00000001)

SENSOR_INFO_TIMESTAMP_SOURCE_UNKNOWN

public static final int SENSOR_INFO_TIMESTAMP_SOURCE_UNKNOWN

Timestamps from CaptureResult#SENSOR_TIMESTAMP are in nanoseconds and monotonic, but can not be compared to timestamps from other subsystems (e.g. accelerometer, gyro etc.), or other instances of the same or different camera devices in the same system with accuracy. However, the timestamps are roughly in the same timebase as SystemClock.uptimeMillis(). The accuracy is sufficient for tasks like A/V synchronization for video recording, at least, and the timestamps can be directly used together with timestamps from the audio subsystem for that task.

Timestamps between streams and results for a single camera instance are comparable, and the timestamps for all buffers and the result metadata generated by a single capture are identical.

SENSOR_TEST_PATTERN_MODE_COLOR_BARS

public static final int SENSOR_TEST_PATTERN_MODE_COLOR_BARS

All pixel data is replaced with an 8-bar color pattern.

The vertical bars (left-to-right) are as follows:

100% white
yellow
cyan
green
magenta
red
blue
black

In general the image would look like the following:

W Y C G M R B K
 W Y C G M R B K
 W Y C G M R B K
 W Y C G M R B K
 W Y C G M R B K
 . . . . . . . .
 . . . . . . . .
 . . . . . . . .

 (B = Blue, K = Black)

Each bar should take up 1/8 of the sensor pixel array width. When this is not possible, the bar size should be rounded down to the nearest integer and the pattern can repeat on the right side.

Each bar's height must always take up the full sensor pixel array height.

Each pixel in this test pattern must be set to either 0% intensity or 100% intensity.

CaptureRequest.SENSOR_TEST_PATTERN_MODE

Constant Value: 2 (0x00000002)

SENSOR_TEST_PATTERN_MODE_COLOR_BARS_FADE_TO_GRAY

public static final int SENSOR_TEST_PATTERN_MODE_COLOR_BARS_FADE_TO_GRAY

The test pattern is similar to COLOR_BARS, except that each bar should start at its specified color at the top, and fade to gray at the bottom.

Furthermore each bar is further subdivided into a left and right half. The left half should have a smooth gradient, and the right half should have a quantized gradient.

In particular, the right half's should consist of blocks of the same color for 1/16th active sensor pixel array width.

The least significant bits in the quantized gradient should be copied from the most significant bits of the smooth gradient.

The height of each bar should always be a multiple of 128. When this is not the case, the pattern should repeat at the bottom of the image.

SENSOR_TEST_PATTERN_MODE_CUSTOM1

public static final int SENSOR_TEST_PATTERN_MODE_CUSTOM1

Constant Value: 256 (0x00000100)

SENSOR_TEST_PATTERN_MODE_OFF

public static final int SENSOR_TEST_PATTERN_MODE_OFF

This is the default if the key is not set.

See also:

CaptureRequest.SENSOR_TEST_PATTERN_MODE

Constant Value: 0 (0x00000000)

SENSOR_TEST_PATTERN_MODE_PN9

public static final int SENSOR_TEST_PATTERN_MODE_PN9

All pixel data is replaced by a pseudo-random sequence generated from a PN9 512-bit sequence (typically implemented in hardware with a linear feedback shift register).

The generator should be reset at the beginning of each frame, and thus each subsequent raw frame with this test pattern should be exactly the same as the last.

CaptureRequest.SENSOR_TEST_PATTERN_MODE

Constant Value: 4 (0x00000004)

SENSOR_TEST_PATTERN_MODE_SOLID_COLOR

public static final int SENSOR_TEST_PATTERN_MODE_SOLID_COLOR

Each pixel in [R, G_even, G_odd, B] is replaced by its respective color channel provided in CaptureRequest#SENSOR_TEST_PATTERN_DATA.

For example:

android.testPatternData = [0, 0xFFFFFFFF, 0xFFFFFFFF, 0]

All green pixels are 100% green. All red/blue pixels are black.

android.testPatternData = [0xFFFFFFFF, 0, 0xFFFFFFFF, 0]

All red pixels are 100% red. Only the odd green pixels are 100% green. All blue pixels are 100% black.
