Module controls

Structs

AeEnable

Enable or disable the AEGC algorithm. When this control is set to true, both ExposureTimeMode and AnalogueGainMode are set to auto, and if this control is set to false then both are set to manual.

AeFlickerDetected

Flicker period detected in microseconds.

AeFlickerPeriod

Manual flicker period in microseconds.

AfWindows

The focus windows used by the AF algorithm when AfMetering is set to AfMeteringWindows.

AnalogueGain

Analogue gain value applied in the sensor device.

AwbEnable

Enable or disable the AWB.

AwbLocked

Report the lock status of a running AWB algorithm.

Brightness

Specify a fixed brightness parameter.

ColourCorrectionMatrix

The 3x3 matrix that converts camera RGB to sRGB within the imaging pipeline.

ColourGains

Pair of gain values for the Red and Blue colour channels, in that order.

ColourTemperature

ColourTemperature of the frame, in kelvin.

Contrast

Specify a fixed contrast parameter.

DebugMetadataEnable

Enable or disable the debug metadata.

DigitalGain

Digital gain value applied during the processing steps applied to the image as captured from the sensor.

ExposureTime

Exposure time for the frame applied in the sensor device.

ExposureValue

Specify an Exposure Value (EV) parameter.

FaceDetectFaceIds

Each detected face is given a unique ID that is valid for as long as the face is visible to the camera device. A face that leaves the field of view and later returns may be assigned a new ID. The number of values should be the number of faces reported in FaceDetectFaceRectangles.

FaceDetectFaceLandmarks

Array of human face landmark coordinates in format […, left_eye_i, right_eye_i, mouth_i, left_eye_i+1, …], with i = index of face. The number of values should be 3 * the number of faces reported in FaceDetectFaceRectangles.

FaceDetectFaceRectangles

Boundary rectangles of the detected faces. The number of values is the number of detected faces.

FaceDetectFaceScores

Confidence score of each of the detected faces. The range of score is [0, 100]. The number of values should be the number of faces reported in FaceDetectFaceRectangles.

FocusFoM

Reports a Figure of Merit (FoM) to indicate how in-focus the frame is.

FrameDuration

The instantaneous frame duration from start of frame exposure to start of next exposure, expressed in microseconds.

FrameDurationLimits

The minimum and maximum (in that order) frame duration, expressed in microseconds.

Gamma

Specify a fixed gamma value.

LensPosition

Set and report the focus lens position.

Lux

Report an estimate of the current illuminance level in lux.

MaxLatency

The maximum number of frames that can occur after a request (different than the previous) has been submitted, and before the result’s state becomes synchronized. A value of -1 indicates unknown latency, and 0 indicates per-frame control. Currently identical to ANDROID_SYNC_MAX_LATENCY.

PipelineDepth

Specifies the number of pipeline stages the frame went through from when it was exposed to when the final completed result was available to the framework. Always less than or equal to PipelineMaxDepth. Currently identical to ANDROID_REQUEST_PIPELINE_DEPTH.

Saturation

Specify a fixed saturation parameter.

ScalerCrop

Sets the image portion that will be scaled to form the whole of the final output image.

SensorBlackLevels

Reports the sensor black levels used for processing a frame.

SensorRollingShutterSkew

Control to report the time between the start of exposure of the first row and the start of exposure of the last row. Currently identical to ANDROID_SENSOR_ROLLING_SHUTTER_SKEW

SensorTemperature

Temperature measure from the camera sensor in Celsius.

SensorTimestamp

The time when the first row of the image sensor active array is exposed.

Sharpness

Intensity of the sharpening applied to the image.

Enums

AfTrigger

Start an autofocus scan.

AnalogueGainMode

Controls the source of the analogue gain that is applied to the image sensor.

AwbMode

Specify the range of illuminants to use for the AWB algorithm.

AwbState

Control to report the current AWB algorithm state. Currently identical to ANDROID_CONTROL_AWB_STATE.

ColorCorrectionAberrationMode

Control to select the color correction aberration mode. Currently identical to ANDROID_COLOR_CORRECTION_ABERRATION_MODE.

ControlId

ExposureTimeMode

Controls the source of the exposure time that is applied to the image sensor.

FaceDetectMode
