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.
