<p>Image recognition, extraction, and data compression is carried out on the basis of colors. There are provided a judgment section 14 for judging a color difference between a color of each pixel constituting an image and each element of a color table; an image replacement section 16 for replacing, in accordance with the result of judgment, the color of each pixel with an element, among elements of the color table, which minimizes the color difference relative to the color of the each pixel; and a pixel integration section for integrating the adjoining pixels after the replacement, if colors of pixels positionally adjoining in an original image are contained in regions adjoining in a divided color space. A single color replaced with an element of the color table is imparted to a group of pixels integrated by the pixel integration section 18. <IMAGE></p> |
