Elements

• VideoProcAmp_Brightness
  Specifies the brightness, also called the black level. For NTSC, the value is expressed in IRE units * 100. For non-NTSC sources, the units are arbitrary, with zero representing blanking and 10,000 representing pure white. Values range from –10,000 to 10,000.

• VideoProcAmp_Contrast
  Specifies the contrast, expressed as gain factor * 100. Values range from zero to 10,000.

• VideoProcAmp_Hue
  Specifies the hue, in degrees * 100. Values range from -180,000 to 180,000 (-180 to +180 degrees).

• VideoProcAmp_Saturation
  Specifies the saturation. Values range from 0 to 10,000.

• VideoProcAmp_Sharpness
  Specifies the sharpness. Values range from 0 to 100.

• VideoProcAmp_Gamma
  Specifies the gamma, as gamma * 100. Values range from 1 to 500.

• VideoProcAmp_ColorEnable
  Specifies the color enable setting. The possible values are 0 (off) and 1 (on).

• VideoProcAmp_WhiteBalance
  Specifies the white balance, as a color temperature in degrees Kelvin. The range of values depends on the device.

• VideoProcAmp_BacklightCompensation
  Specifies the backlight compensation setting. Possible values are 0 (off) and 1 (on).

• VideoProcAmp_Gain
  Specifies the gain adjustment. Zero is normal. Positive values are brighter and negative values are darker. The range of values depends on the device.
