ltmmVideoProcAmp_Contrast

[1] Specifies the contrast, expressed as gain factor * 100. Values range from zero to 10,000.

ltmmVideoProcAmp_Hue

[2] Specifies the hue, in degrees * 100. Values range from -180,000 to 180,000 (-180 to +180 degrees).

ltmmVideoProcAmp_Saturation

[3] Specifies the saturation. Values range from 0 to 10,000.

ltmmVideoProcAmp_Sharpness

[4] Specifies the sharpness. Values range from 0 to 100.

ltmmVideoProcAmp_Gamma

[5] Specifies the gamma, as gamma * 100. Values range from 1 to 500.

ltmmVideoProcAmp_ColorEnable

[6] Specifies the color enable setting. The possible values are 0 (off) and 1 (on).

ltmmVideoProcAmp_WhiteBalance
