    摘要: A color image processing technique using optics to separate an original color image into a plurality of colors. These colors are photoelectrically converted to electric signals. Color information signals are then generated from these electric signals. The color information signals are coded by comparing them with a threshold value. An individualized set of such threshold values is provided for each of the plurality of colors. In one embodiment, a luminance signal is provided from the color information signals. The luminance signal is utilized in response to a monochrome code selection signal to enable the original color image to be reproduced as a monochrome image. Color gamut information and color density information of the color gamut can be obtained from the color information signals during a first scan of a document bearing the color image.
