Example:
// Set a red gain value of 1.23 => input value should be 315 = round (1.23 * 256.0)
gain_red 315
8.8.15 gain_blue <gain>
Same as gain_red but for blue color channel.
8.8.16 gain_green <gain>
Same as gain_red but for green color channel.
8.8.17 black_master <offset-red> <offset-green> <offset-blue>
Sets the black-level offset for red, green and blue-components for selected output channel. The processing is done
in linear RGB domain (pre gamma).
red_out = (red_in – offset-red) *4095 / (4095 – offset-red)
Value Reset Minimal Maximal
offset
0 -2047 2048
Example 1:
// Set black-level for all components to 100
black_master 100
Example 2:
// Set black-level for red to 10, for green to 20 and blue to 30
black_master 10 20 30
8.8.18 black_red <offset>
