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