Constant

Description

ltmmVideoProcAmp_Brightness

[0] 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.

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

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

ltmmVideoProcAmp_BacklightCompensation

[8] Specifies the backlight compensation setting. Possible values are 0 (off) and 1 (on).

ltmmVideoProcAmp_Gain

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