Table 2-29. Component Y Contrast Register

Subaddress 11h

Default 80h

7 6 5 4 3 2 1 0

Y contrast [7:0]

Y contrast [7:0]:

This register works only with YPbPr component video. For RGB video, use the AFE gain registers.

0000 0000 = minimum

1000 0000 = default

1111 1111 = maximum

For component video outputs, the total luminance gain relative to the nominal luminance gain as a function of the Y contrast [7:0] is as

follows:

Y Gain = (nominal_luminance_gain) × (Y contrast [7:0] / 128)

Table 2-30. Component Pb Saturation Register

Subaddress 12h

Default 80h

7 6 5 4 3 2 1 0

Pb saturation [7:0]

Pb saturation:

This register works only with YPbPr component video. For RGB video, use the AFE gain registers.

0000 0000 = minimum

1000 0000 = default

1111 1111 = maximum

For component video, the total Pb gain relative to the nominal Pb gain as a function of the Pb saturation [7:0] setting is as follows:

Pb Gain = (nominal_chrominance_gain) × (Pb saturation [7:0] / 128)

Table 2-31. Component Y Brightness Register

Subaddress 14h

Default 80h

7 6 5 4 3 2 1 0

Y brightness [7:0]

Y brightness:

This register works only with YPbPr component video. For RGB video, use the AFE gain registers.

0000 0000 = minimum

1000 0000 = default

1111 1111 = maximum

For component video, the output black level relative to the nominal black level (64 out of 1024) as a function of Y brightness [7:0] is as

follows:

Black Level = nominal_black_level + (Y brightness [7:0] – 128)
