CAMERAResult CAMERA_I2CAutoWhiteBalanceAsync(CAMERASelect camera, BOOL on, CAMERACallback callback, void *arg);
| camera | Camera to configure (CAMERA_SELECT_IN, CAMERA_SELECT_OUT, or CAMERA_SELECT_BOTH). |
| on | If TRUE, the auto-adjustment feature is enabled. If FALSE, it is disabled. |
| callback | Function that is called when asynchronous processing has completed. |
| arg | Arguments when the callback function is invoked. |
Returns CAMERA_RESULT_SUCCESS if configuration was successful.
Enables or disables the auto-adjustment feature for the camera's white balance when it is set to "auto" with CAMERA_WHITE_BALANCE_NORMAL. The exposure value will be unstable immediately after the camera is started with the CAMERA_I2CActivate function. A value of INVALID_COMMAND is returned if CAMERA_WHITE_BALANCE_NORMAL is not set. Calling the CAMERA_I2CWhiteBalance function resets the value set by this function and enables the auto-adjustment feature.
Unlike CAMERA_I2CAutoWhiteBalance, the CAMERA_I2CAutoWhiteBalanceAsync function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.
