Document

The desired mode for the camera device's auto-exposure routine.

This control is only effective if CaptureRequest#CONTROL_MODE android.control.mode is AUTO.

When set to any of the ON modes, the camera device's auto-exposure routine is enabled, overriding the application's selected exposure time, sensor sensitivity, and frame duration ( CaptureRequest#SENSOR_EXPOSURE_TIME android.sensor.exposureTime , CaptureRequest#SENSOR_SENSITIVITY android.sensor.sensitivity , and CaptureRequest#SENSOR_FRAME_DURATION android.sensor.frameDuration ).
