Abstract

PURPOSE:To perform processing on real time, by obtaining a plurality of color data from an optical image reading an original optically and converting one of the data into a data representing different color from the original data. CONSTITUTION:Color discrimination is made at a color discriminator DMC based on, e.g., bindary blue signals BSB and binary red signal BSR obtained from the reading of an original optically, and three color data such as blue DBU, red DRE and black DBK data are generated. The discrimination of the designated area is made based on the blue data DBU. The blue data is applied to a main and a sub-scanning compressor CDM and CDS, where compressed data DCS are obtained. This data DCS is sequentially read out on the 1st-3rd line memories ML1-ML3 and stored as data DM1-DM3, which are inputted to a data selector DCL as the 4th line memory data DM4 via an edge detector EDE and an area detector DEA, and the DM4 is compared with the 5th line memory data DM5 for the discrimination of the area.
