Syntax

typedef enum tagVideoProcAmpProperty {
  VideoProcAmp_Brightness,
  VideoProcAmp_Contrast,
  VideoProcAmp_Hue,
  VideoProcAmp_Saturation,
  VideoProcAmp_Sharpness,
  VideoProcAmp_Gamma,
  VideoProcAmp_ColorEnable,
  VideoProcAmp_WhiteBalance,
  VideoProcAmp_BacklightCompensation,
  VideoProcAmp_Gain
} VideoProcAmpProperty;

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.
