Brightness[7:0]
Brightness[7:0]: This register works for CVBS and S-Video luminance.
1111 1111 = 255 (bright)
1000 0000 = 128 (default)
0000 0000 = 0 (dark)
The output black level relative to the nominal black level (16 out of 256) as a function of the
Brightness[7:0] setting and the Contrast[7:0] setting is as follows:
Black Level = nominal_black_level + (Brightness[7:0] – 128) + (438 / 4) × (1 - Contrast[7:0] / 128)
