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.
These bits control the contrast. They may have a value of 0x (“0000 0000”) to 1.992x (“1111
1111”). A value of 1x (“1000 0000”) has no effect on the data.
These bits control the color hue. They may have a value of +30 degrees (“0111 1111”) to -30
degrees (“1111 1111”). A value of 0 degrees (“0000 0000”) has no effect on the color data.
These bits control the color saturation. They may have a value of 0x (“0000 0000”) to 1.992x
(“1111 1111”). A value of 1x (“1000 0000”) has no effect on the color data. A value of 0x (“0000
0000”) disables the color information.
These bits control the amount of digital gain applied to 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 enabled by the selection of “fixed gain control” mode in the
