Abstract
Abstract An image processing method wherein an image is extracted into a plurality of color signals, picture element informations are given in color designating color codes and density data thereto, and the color codes are subjected after the color extraction to a color ghost correction. The color codes are determined by a color pattern formed from color codes of picture elements noted and around thereof. The extracted image is converted photo-electrically by extracting devices (l, 2), plural bit data are obtained from converted signal by a device (4), extracting color code and density data are extracted on the basis of the plural bit data by a device (5), and the color code are processed by devices (ll0, 202, 295).
