Setting Values for Brightness, Contrast, and Gamma
You can select Brightness, Contrast, and Gamma settings per color mode. For example, the settings for color mode may differ from the settings for black and white scanning.
The Brightness setting affects the amount of "light" in an image. With a high Brightness setting, less of the background or fill colors and highlighted areas of an image are enhanced. With a low Brightness setting, more of the background or fill colors and highlighted areas are enhanced.
For black and white or grayscale scanning, select Auto Brightness if you want Kofax VRS to automatically apply the optimal Brightness setting.
The Contrast setting affects the amount of difference between the lightest and darkest areas in an image.
The Gamma setting affects the conversion of light intensity into pixels; typically, it is not necessary to adjust this value.
