2 * Auto gain algorithm for camera's with a coarse exposure control
21 /* Autogain + exposure algorithm for cameras with a coarse exposure control
22 (usually this means we can only control the clockdiv to change exposure)
24 example, will lead to a huge exposure change (it effectively doubles),
26 80 %) and if that does not help, only then changes exposure. This leads
28 certain points of the knee graph will only try to adjust exposure,
29 which leads to oscilating as one exposure step is huge.
34 Returns 0 if no changes were made, 1 if the gain and or exposure settings
