Contrast [7:0]
Contrast [7:0]:
This register works for CVBS and S-Video luminance. See subaddress 2Fh.
0000 0000 = 0 (minimum contrast)
1000 0000 = 128 (default)
1111 1111 = 255 (maximum contrast)
For composite and S-Video outputs, the total luminance gain relative to the nominal luminance gain as a function of the Contrast [7:0]
setting is as follows.
Luminance Gain = (nominal_luminance_gain)
× [Contrast [7:0] / 64 / (2^MC) + MC – 1]
Where MC is the contrast multiplier setting in the Brightness and Contrast Range Extender register at I
2C subaddress 2Fh.

Saturation [7:0]
Saturation [7:0]:
This register works for CVBS and S-Video chrominance.
0000 0000 = 0 (no color)
1000 0000 = 128 (default)
1111 1111 = 255 (maximum)
For composite and S-Video outputs, the total chrominance gain relative to the nominal chrominance gain as a function of the Saturation
[7:0] setting is as follows.
Chrominance Gain = (nominal_chrominance_gain)
× (Saturation [7:0] / 128)

Hue [7:0]
Hue [7:0]:
Does not apply to a component or SECAM video. This register works for CVBS and S-Video chrominance.
