Brightness
Adjust
These bits control the brightness. They may have a value of +63 (“011 1111”) to -64 (“100
0000”), with positive values increasing brightness. A value of 0 (“000 0000”) has no effect
on the data.

Color Gain
Adjust
These bits control the amount of gain control for the color difference (CbCr) signals. They
may have a value of 0.5x (“0010 0000”) to 3.98x (“1111 1111”). A value of 1x (“0100
0000”) has no effect on the data. This register is ignored unless the color gain control
mode selection is “fixed gain control”.
