static val CONTROL_AE_MODE_OFF: Int

The camera device's autoexposure routine is disabled.

The application-selected android.sensor.exposureTime, android.sensor.sensitivity and android.sensor.frameDuration 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 android.control.awbMode, android.control.afMode, android.control.awbLock, and android.control.afTrigger for more details.

LEGACY devices do not support the OFF mode and will override attempts to use this value to ON.

Value: 0

CONTROL_AE_MODE_ON

static val CONTROL_AE_MODE_ON: Int

The camera device's autoexposure routine is active, with no flash control.

The application's values for android.sensor.exposureTime, android.sensor.sensitivity, and android.sensor.frameDuration are ignored. The application has control over the various android.flash.* fields.

Value: 1

CONTROL_AE_MODE_ON_ALWAYS_FLASH

static val CONTROL_AE_MODE_ON_ALWAYS_FLASH: Int

Like ON, except that the camera device also controls the camera's flash unit, always firing it for still captures.

The flash may be fired during a precapture sequence (triggered by android.control.aePrecaptureTrigger) and will always be fired for captures for which the android.control.captureIntent field is set to STILL_CAPTURE

Value: 3

CONTROL_AE_MODE_ON_AUTO_FLASH

static val CONTROL_AE_MODE_ON_AUTO_FLASH: Int

Like ON, except that the camera device also controls the camera's flash unit, firing it in low-light conditions.

The flash may be fired during a precapture sequence (triggered by android.control.aePrecaptureTrigger) and may be fired for captures for which the android.control.captureIntent field is set to STILL_CAPTURE

Value: 2

CONTROL_AE_MODE_ON_AUTO_FLASH_REDEYE

static val CONTROL_AE_MODE_ON_AUTO_FLASH_REDEYE: Int

Like ON_AUTO_FLASH, but with automatic red eye reduction.

Value: 4

CONTROL_AE_MODE_ON_EXTERNAL_FLASH

static val CONTROL_AE_MODE_ON_EXTERNAL_FLASH: Int

An external flash has been turned on.

It informs the camera device that an external flash has been turned on, and that metering (and continuous focus if active) should be quickly recalculated to account for the external flash. Otherwise, this mode acts like ON.

When the external flash is turned off, AE mode should be changed to one of the other available AE modes.

If the camera device supports AE external flash mode, android.control.aeState must be FLASH_REQUIRED after the camera device finishes AE scan and it's too dark without flash.

Value: 5

CONTROL_AE_MODE_ON_LOW_LIGHT_BOOST_BRIGHTNESS_PRIORITY

static val CONTROL_AE_MODE_ON_LOW_LIGHT_BOOST_BRIGHTNESS_PRIORITY: Int

Like 'ON' but applies additional brightness boost in low light scenes.

When the scene lighting conditions are within the range defined by android.control.lowLightBoostInfoLuminanceRange this mode will apply additional brightness boost.

This mode will automatically adjust the intensity of low light boost applied according to the scene lighting conditions. A darker scene will receive more boost while a brighter scene will receive less boost.

This mode can ignore the set target frame rate to allow more light to be captured which can result in choppier motion. The frame rate can extend to lower than the android.control.aeAvailableTargetFpsRanges but will not go below 10 FPS. This mode can also increase the sensor sensitivity gain which can result in increased luma and chroma noise. The sensor sensitivity gain can extend to higher values beyond android.sensor.info.sensitivityRange. This mode may also apply additional processing to recover details in dark and bright areas of the image,and noise reduction at high sensitivity gain settings to manage the trade-off between light sensitivity and capture noise.

This mode is restricted to two output surfaces. One output surface type can either be SurfaceView or TextureView. Another output surface type can either be MediaCodec or MediaRecorder. This mode cannot be used with a target FPS range higher than 30 FPS.

If the session configuration is not supported, the AE mode reported in the CaptureResult will be 'ON' instead of 'ON_LOW_LIGHT_BOOST_BRIGHTNESS_PRIORITY'.

When this AE mode is enabled, the CaptureResult field android.control.lowLightBoostState will indicate when low light boost is 'ACTIVE' or 'INACTIVE'. By default android.control.lowLightBoostState will be 'INACTIVE'.

The low light boost is 'ACTIVE' once the scene lighting condition is less than the upper bound lux value defined by android.control.lowLightBoostInfoLuminanceRange. This mode will be 'INACTIVE' once the scene lighting condition is greater than the upper bound lux value defined by android.control.lowLightBoostInfoLuminanceRange.

Value: 6

static val CONTROL_AE_STATE_LOCKED: Int

AE has been locked.

Value: 3

CONTROL_AE_STATE_PRECAPTURE

static val CONTROL_AE_STATE_PRECAPTURE: Int

AE has been asked to do a precapture sequence and is currently executing it.

Precapture can be triggered through setting android.control.aePrecaptureTrigger to START. Currently active and completed (if it causes camera device internal AE lock) precapture metering sequence can be canceled through setting android.control.aePrecaptureTrigger to CANCEL.

Once PRECAPTURE completes, AE will transition to CONVERGED or FLASH_REQUIRED as appropriate. This is a transient state, the camera device may skip reporting this state in capture result.

Value: 5

CONTROL_AE_STATE_SEARCHING

Value: 1

CONTROL_AF_MODE_AUTO

static val CONTROL_AF_MODE_AUTO: Int

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 android.lens.info.minimumFocusDistance to determine if lens is fixed-focus.

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

Value: 1

CONTROL_AF_MODE_CONTINUOUS_PICTURE

static val CONTROL_AF_MODE_CONTINUOUS_PICTURE: Int

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.

Value: 4

CONTROL_AF_MODE_CONTINUOUS_VIDEO

static val CONTROL_AF_MODE_CONTINUOUS_VIDEO: Int

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.

Value: 3

CONTROL_AF_MODE_EDOF

static val CONTROL_AF_MODE_EDOF: Int

Extended depth of field (digital focus) mode.

The camera device will produce images with an extended depth of field automatically; no special focusing operations need to be done before taking a picture.

AF triggers are ignored, and the AF state will always be INACTIVE.

Value: 5

CONTROL_AF_MODE_MACRO

static val CONTROL_AF_MODE_MACRO: Int

Close-up focusing 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). This mode is optimized for focusing on objects very close to the camera.

When that trigger is activated, AF will transition to ACTIVE_SCAN, then to the outcome of the scan (FOCUSED or NOT_FOCUSED). Triggering cancel AF resets the lens position to default, and sets the AF state to INACTIVE.

Value: 2

CONTROL_AF_MODE_OFF

CONTROL_EXTENDED_SCENE_MODE_BOKEH_CONTINUOUS

static val CONTROL_EXTENDED_SCENE_MODE_BOKEH_CONTINUOUS: Int

Bokeh effect must not slow down capture rate relative to sensor raw output, and the effect is applied to all processed streams no larger than the maximum streaming dimension. This mode should be used if performance and power are a priority, such as video recording.

Value: 2

CONTROL_EXTENDED_SCENE_MODE_BOKEH_STILL_CAPTURE

static val CONTROL_EXTENDED_SCENE_MODE_BOKEH_STILL_CAPTURE: Int

High quality bokeh mode is enabled for all non-raw streams (including YUV, JPEG, and IMPLEMENTATION_DEFINED) when capture intent is STILL_CAPTURE. Due to the extra image processing, this mode may introduce additional stall to non-raw streams. This mode should be used in high quality still capture use case.

Value: 1

Manual control of capture parameters is disabled. All controls in android.control.* besides sceneMode take effect.

Value: 1

CONTROL_MODE_OFF

static val CONTROL_MODE_OFF: Int

Full application control of pipeline.

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 android.control.captureIntent 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.

Value: 0

CONTROL_MODE_OFF_KEEP_STATE

static val CONTROL_MODE_OFF_KEEP_STATE: Int

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.

Value: 3

CONTROL_MODE_USE_EXTENDED_SCENE_MODE

static val CONTROL_MODE_USE_EXTENDED_SCENE_MODE: Int

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).

Value: 4

CONTROL_MODE_USE_SCENE_MODE

static val CONTROL_MODE_USE_SCENE_MODE: Int

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. android.control.availableSceneModes contain some modes other than DISABLED).

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

static val CONTROL_SCENE_MODE_CANDLELIGHT: Int

Optimized for dim settings where the main light source is a candle.

Value: 15

CONTROL_SCENE_MODE_DISABLED

static val CONTROL_SCENE_MODE_DISABLED: Int

Indicates that no scene modes are set for a given capture request.

Value: 0

CONTROL_SCENE_MODE_FACE_PRIORITY

static val CONTROL_SCENE_MODE_FACE_PRIORITY: Int

If face detection support exists, use face detection data for auto-focus, auto-white balance, and auto-exposure routines.

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

Unlike the other scene modes, android.control.aeMode, android.control.awbMode, and android.control.afMode remain active when FACE_PRIORITY is set.

Value: 1

CONTROL_SCENE_MODE_FIREWORKS

static val CONTROL_SCENE_MODE_FIREWORKS: Int

Optimized for nighttime photos of fireworks.

Value: 12

CONTROL_SCENE_MODE_HDR

static val CONTROL_SCENE_MODE_HDR: Int

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 android.control.captureIntent 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.

Value: 18

CONTROL_SCENE_MODE_HIGH_SPEED_VIDEO

static val CONTROL_SCENE_MODE_HIGH_SPEED_VIDEO: Int

Deprecated: Please refer to this API documentation to find the alternatives

This is deprecated, please use android.hardware.camera2.CameraDevice#createConstrainedHighSpeedCaptureSession and android.hardware.camera2.CameraConstrainedHighSpeedCaptureSession#createHighSpeedRequestList 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 android.control.aeTargetFpsRange.

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 android.control.mode == AUTO. This means that all other android.control.* fields continue to work, such as

• android.control.aeTargetFpsRange
• android.control.aeExposureCompensation
• android.control.aeLock
• android.control.awbLock
• android.control.effectMode
• android.control.aeRegions
• android.control.afRegions
• android.control.awbRegions
• android.control.afTrigger
• android.control.aePrecaptureTrigger
• android.control.zoomRatio

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

• android.flash.mode (automatic flash for still capture will not work since aeMode is ON)
• android.lens.opticalStabilizationMode (if it is supported)
• android.scaler.cropRegion
• android.statistics.faceDetectMode

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 satisfied, the controls of this mode and android.control.aeTargetFpsRange will be ignored by the camera device, the camera device will fall back to android.control.mode == AUTO, and the returned capture result metadata will give the fps range chosen 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.

CONTROL_SETTINGS_OVERRIDE_OFF

static val CONTROL_SETTINGS_OVERRIDE_OFF: Int

No keys are applied sooner than the other keys when applying CaptureRequest settings to the camera device. This is the default value.

Value: 0

CONTROL_SETTINGS_OVERRIDE_ZOOM

static val CONTROL_SETTINGS_OVERRIDE_ZOOM: Int

Zoom related keys are applied sooner than the other keys in the CaptureRequest. The zoom related keys are:

• android.control.zoomRatio
• android.scaler.cropRegion
• android.control.aeRegions
• android.control.awbRegions
• android.control.afRegions

Even though android.control.aeRegions, android.control.awbRegions, and android.control.afRegions are not directly zoom related, applications typically scale these regions together with android.scaler.cropRegion to have a consistent mapping within the current field of view. In this aspect, they are related to android.scaler.cropRegion and android.control.zoomRatio.

Value: 1

CONTROL_VIDEO_STABILIZATION_MODE_OFF

static val CONTROL_VIDEO_STABILIZATION_MODE_OFF: Int

Video stabilization is disabled.

Value: 0

Video stabilization is enabled.

Value: 1

CONTROL_VIDEO_STABILIZATION_MODE_PREVIEW_STABILIZATION

static val CONTROL_VIDEO_STABILIZATION_MODE_PREVIEW_STABILIZATION: Int

Preview stabilization, where the preview in addition to all other non-RAW streams are stabilized with the same quality of stabilization, is enabled. This mode aims to give clients a 'what you see is what you get' effect. In this mode, the FoV reduction will be a maximum of 20 % both horizontally and vertically (10% from left, right, top, bottom) for the given zoom ratio / crop region. The resultant FoV will also be the same across all processed streams (that have the same aspect ratio).

Value: 2

DISTORTION_CORRECTION_MODE_FAST

static val DISTORTION_CORRECTION_MODE_FAST: Int

Lens distortion correction is applied without reducing frame rate relative to sensor output. It may be the same as OFF if distortion correction would reduce frame rate relative to sensor.

Value: 1

DISTORTION_CORRECTION_MODE_HIGH_QUALITY

static val DISTORTION_CORRECTION_MODE_HIGH_QUALITY: Int

High-quality distortion correction is applied, at the cost of possibly reduced frame rate relative to sensor output.

static val EDGE_MODE_HIGH_QUALITY: Int

Apply high-quality edge enhancement, at a cost of possibly reduced output frame rate.

Value: 2

EDGE_MODE_OFF

static val EDGE_MODE_OFF: Int

No edge enhancement is applied.

Value: 0

EDGE_MODE_ZERO_SHUTTER_LAG

static val EDGE_MODE_ZERO_SHUTTER_LAG: Int

Edge enhancement is applied at different levels for different output streams, based on resolution. Streams at maximum recording resolution (see android.hardware.camera2.CameraDevice#createCaptureSession) 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 (android.request.availableCapabilities lists either of those capabilities) and it will be the default mode for CAMERA3_TEMPLATE_ZERO_SHUTTER_LAG template.

Value: 3

INFO_SUPPORTED_HARDWARE_LEVEL_3

static val INFO_SUPPORTED_HARDWARE_LEVEL_3: Int

This camera device is capable of YUV reprocessing and RAW data capture, in addition to FULL-level capabilities.

The stream configurations listed in the LEVEL_3, RAW, FULL, LEGACY and LIMITED tables in the documentation are guaranteed to be supported.

The following additional capabilities are guaranteed to be supported:

• YUV_REPROCESSING capability (android.request.availableCapabilities contains YUV_REPROCESSING)
• RAW capability (android.request.availableCapabilities contains RAW)

Value: 3

INFO_SUPPORTED_HARDWARE_LEVEL_EXTERNAL

static val INFO_SUPPORTED_HARDWARE_LEVEL_EXTERNAL: Int

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
  • android.lens.focalLength
  • android.lens.info.hyperfocalDistance
  • android.sensor.info.physicalSize
  • android.sensor.info.whiteLevel
  • android.sensor.blackLevelPattern
  • android.sensor.info.colorFilterArrangement
  • android.sensor.rollingShutterSkew
• The device will report 0 for android.sensor.orientation
• The device has less guarantee on stable framerate, as the framerate partly depends on the external camera being used.

Value: 4

INFO_SUPPORTED_HARDWARE_LEVEL_FULL

static val INFO_SUPPORTED_HARDWARE_LEVEL_FULL: Int

This camera device is capable of supporting advanced imaging applications.

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

A FULL device will support below capabilities:

• BURST_CAPTURE capability (android.request.availableCapabilities contains BURST_CAPTURE)
• Per frame control (android.sync.maxLatency == PER_FRAME_CONTROL)
• Manual sensor control (android.request.availableCapabilities contains MANUAL_SENSOR)
• Manual post-processing control (android.request.availableCapabilities contains MANUAL_POST_PROCESSING)
• The required exposure time range defined in android.sensor.info.exposureTimeRange
• The required maxFrameDuration defined in android.sensor.info.maxFrameDuration

Note: Pre-API level 23, FULL devices also supported arbitrary cropping region (android.scaler.croppingType == FREEFORM); this requirement was relaxed in API level 23, and FULL devices may only support CENTERED cropping.

Value: 1

INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY

static val INFO_SUPPORTED_HARDWARE_LEVEL_LEGACY: Int

This camera device is running in backward compatibility mode.

Only the stream configurations listed in the LEGACY table in the 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 android.request.availableCapabilities.

In addition, the android.control.aePrecaptureTrigger 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.

Value: 2

INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED

static val INFO_SUPPORTED_HARDWARE_LEVEL_LIMITED: Int

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 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 android.control.aePrecaptureTrigger 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 android.control.aeMode, android.control.afMode, or android.control.awbMode)

Additional capabilities may optionally be supported by a LIMITED-level device, and can be checked for in android.request.availableCapabilities.

LENS_INFO_FOCUS_DISTANCE_CALIBRATION_APPROXIMATE

static val LENS_INFO_FOCUS_DISTANCE_CALIBRATION_APPROXIMATE: Int

The lens focus distance is measured in diopters.

However, setting the lens to the same focus distance on separate occasions may result in a different real focus distance, depending on factors such as the orientation of the device, the age of the focusing mechanism, and the device temperature.

Value: 1

LENS_INFO_FOCUS_DISTANCE_CALIBRATION_CALIBRATED

static val LENS_INFO_FOCUS_DISTANCE_CALIBRATION_CALIBRATED: Int

The lens focus distance is measured in diopters, and is calibrated.

The lens mechanism is calibrated so that setting the same focus distance is repeatable on multiple occasions with good accuracy, and the focus distance corresponds to the real physical distance to the plane of best focus.

Value: 2

LENS_INFO_FOCUS_DISTANCE_CALIBRATION_UNCALIBRATED

static val LENS_INFO_FOCUS_DISTANCE_CALIBRATION_UNCALIBRATED: Int

The lens focus distance is not accurate, and the units used for android.lens.focusDistance do not correspond to any physical units.

Setting the lens to the same focus distance on separate occasions may result in a different real focus distance, depending on factors such as the orientation of the device, the age of the focusing mechanism, and the device temperature. The focus distance value will still be in the range of [0, android.lens.info.minimumFocusDistance], where 0 represents the farthest focus.

Value: 0

This is the default value for API levels before Android P.

Value: 0

LENS_POSE_REFERENCE_UNDEFINED

static val LENS_POSE_REFERENCE_UNDEFINED: Int

The camera device cannot represent the values of android.lens.poseTranslation and android.lens.poseRotation accurately enough. One such example is a camera device on the cover of a foldable phone: in order to measure the pose translation and rotation, some kind of hinge position sensor would be needed.

The value of android.lens.poseTranslation must be all zeros, and android.lens.poseRotation must be values matching its default facing.

Value: 2

LENS_STATE_MOVING

Value: 0

LOGICAL_MULTI_CAMERA_SENSOR_SYNC_TYPE_APPROXIMATE

static val LOGICAL_MULTI_CAMERA_SENSOR_SYNC_TYPE_APPROXIMATE: Int

A software mechanism is used to synchronize between the physical cameras. As a result, the timestamp of an image from a physical stream is only an approximation of the image sensor start-of-exposure time.

Value: 0

LOGICAL_MULTI_CAMERA_SENSOR_SYNC_TYPE_CALIBRATED

static val LOGICAL_MULTI_CAMERA_SENSOR_SYNC_TYPE_CALIBRATED: Int

The camera device supports frame timestamp synchronization at the hardware level, and the timestamp of a physical stream image accurately reflects its start-of-exposure time.

Value: 1

NOISE_REDUCTION_MODE_FAST

static val NOISE_REDUCTION_MODE_OFF: Int

No noise reduction is applied.

Value: 0

NOISE_REDUCTION_MODE_ZERO_SHUTTER_LAG

static val NOISE_REDUCTION_MODE_ZERO_SHUTTER_LAG: Int

Noise reduction is applied at different levels for different output streams, based on resolution. Streams at maximum recording resolution (see android.hardware.camera2.CameraDevice#createCaptureSession) 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.

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

Value: 4

REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE

static val REQUEST_AVAILABLE_CAPABILITIES_BACKWARD_COMPATIBLE: Int

The minimal set of capabilities that every camera device (regardless of android.info.supportedHardwareLevel) 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.

Value: 0

REQUEST_AVAILABLE_CAPABILITIES_BURST_CAPTURE

static val REQUEST_AVAILABLE_CAPABILITIES_BURST_CAPTURE: Int

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 android.graphics.ImageFormat#YUV_420_888 format in either android.hardware.camera2.params.StreamConfigurationMap#getOutputSizes or android.hardware.camera2.params.StreamConfigurationMap#getHighResolutionOutputSizes, 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 android.control.aeAvailableTargetFpsRanges 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 android.hardware.camera2.params.StreamConfigurationMap#getHighResolutionOutputSizes, then the list of resolutions for YUV_420_888 from android.hardware.camera2.params.StreamConfigurationMap#getOutputSizes contains at least one resolution >= 8 megapixels, with a minimum frame duration of <= 1/20 s.

If the device supports the android.graphics.ImageFormat#RAW10, android.graphics.ImageFormat#RAW12, android.graphics.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 android.graphics.ImageFormat#PRIVATE format.

In addition, the android.sync.maxLatency field is guaranteed to have a value between 0 and 4, inclusive. android.control.aeLockAvailable and android.control.awbLockAvailable are also guaranteed to be true so burst capture with these two locks ON yields consistent image output.
