Abstract
A color image recognition apparatus capable of judging whether an original is monochromatic or color comprises an image reader for rapidly scanning the original to develop image data and a color display coordinate system for converting the image data to luminance data and color difference data. A pixel color judging unit judges the color of each pixel based upon the luminance data and the color difference data, and a block color judging unit compares the number of color pixels with the number of black pixels contained in each of the plurality of blocks of pixels. An original color judging unit then counts the number of color blocks in the original to judge the color of the original.
