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 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”.
These bits control the amount of gain control for the video signals. They may have a value
of 0.5x (“1100 1110”) to 1.99x (“0011 0011”). A value of 1x (“0110 0111”) has no effect.
Refer to the look-up table following register definitions for other values to load for different
gains. This register is ignored unless the video gain control mode selection is “fixed gain
control”.
