Abstract
Representative pixel data is extracted for each predetermined region in an original image according to priority of color codes representing colors. The representative pixel data constitute a reduced image. The reduced image is a clear and complete reproduction of the original image without line omissions and distortion of a desired linework. M pieces of pixel data on each scanning line are successively read until the pixel data reaches a maximum value Xmax in a main scanning direction. One pixel data having a color code with the highest priority is selected from the read pixel data according to a priority code table TBL. If the color code is not in the priority table, pixel data at a predetermined position in the region of the read pixel data is selected. The results of selection for two adjacent scanning lines are compared based on the priority code table TBL, and final representative pixel data is selected.
