#include <twl/camera.h>CAMERAResult CAMERA_I2CWhiteBalance(CAMERASelect camera, CAMERAWhiteBalance wb); CAMERAResult CAMERA_I2CWhiteBalanceAsync(CAMERASelect camera, CAMERAWhiteBalance wb, CAMERACallback callback, void *arg);
| camera | Camera to configure (CAMERA_SELECT_IN, CAMERA_SELECT_OUT, or CAMERA_SELECT_BOTH). |
| wb | White balance to set. |
| 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.
Sets the camera's white balance.
Unlike CAMERA_I2CWhiteBalance, the CAMERA_I2CWhiteBalanceAsync function returns control immediately and runs asynchronously. Use callback to confirm that processing has completed.
Note:
If camera settings are changed using any of the CAMERA_I2C* functions, the changes may be delayed for approximately one frame before they are applied. Consequently, note that if camera settings are changed while capturing, the application may not be able to get an updated image (an image with changes applied) at the time the application intended.
