26 NOTE: Sensor controls are disabled for now, becouse changing them while
27 streaming sometimes results in out-of-sync video frames. We'll use
28 the default initialization, until we know how to stop and start video
29 in the chip. However, the image quality still looks good under various
30 light conditions.
