The ltmmVideoProcAmpProperty constants specify the video properties on a video capture device. The values listed below can be used with some of the IltmmVideoProcAmp Interface functions.

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.
