1.7 Color saturation control
The color saturation can be enhanced by adjusting the Saturation Factor register 0x2D
(AD_SATURATION, Default = 0x30).
1.8 Gamma Correction
Use register 0x24 (AD_GAMMA) to select one of them:
1.10 Brightness
The Brightness offset can be adjusted by Brightness Offset register 0x2B (AD
Default =0). The default value =0 means the Brightness is not adjusted.
The following examples show how to increase/decrease the Brightness Level:

The following examples show how to set the Saturation to 0, 1, 1.5, and 2:
To boost darker signal to match the video monitor characteristic, gamma correction are performed:
Saturation 0 : AD_SATURATION = 0x00, no color (B/W)
Sharpening Low Tone Threshold.
AD_GAMMA 0 : Gamma = 1 (no Gamma)
AD_GAMMA 1 : Gamma = 1.3
AD_GAMMA 3 : Gamma = 1.8
AD_GAMMA 4 : Gamma = Normal Mode
AD_GAMMA 5 : Gamma = Brighter Mode
AD_GAMMA 6 : Gamma = Higher Contrast Mode
AD_GAMMA 2 : Gamma = 1.5
Increase Brightness by 10: AD_BRIGHT_OFFSET = 0x0A
Decrease Brightness by10: AD_BRIGHT_OFFSET = 0x8A
