Abstract
An image processing apparatus generates color image signals representing an image of a scanned original document. A series of image discriminating units are provided. An edge discrimination unit discriminates edge regions with respect to each pixel. Further discrimination units discriminate other image regions, such as half tone regions, white background regions, photograph regions, or color regions, with respect to each pixel block. Discriminating results are stored in a memory to be used for subsequent image scans.
