Abstract:
1. A color/monochrome copier capable of distinguishing and copying color and monochrome originals with a single scan, comprising: a scanner which generates RGB data from an original; a color/monochrome processor which determines whether the original is color or monochrome based on the RGB data from the scanner; a first data converter which converts the RGB data to CMY data; a data compressor which compresses the CMY data; and a page memory which stores the compressed CMY data, wherein the scanner generates sufficient RGB data in a single scan for the color/monochrome processor to determine if the original is color or monochrome and to produce either a color or monochrome copy therefrom, and wherein a data decompressor decompresses the compressed CMY data from the page memory in accordance with the determination of the color/monochrome processor.
