28 29 Color images fr om CCD cameras typically require a background level adjust- ment. This is accomplished by bringing the background level (or bias) in each color plane down to zero. Each of the Background Level values is subtracted from every image pixel in its color plane. Any pixel values that become nega- tive are forced to zero. The Auto bu[...]
