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 of high frequency luminance signals (either
2.6MHz or Fsc). They may have a value of +12dB (“11 1111”) to -12dB (“00 0100”). A
value of 0dB (“01 0000”) has no effect on the data. This register is ignored if the sharp-
ness mode selection is “disable sharpness control” or “reserved”.
