Image color processing

摘要

A color image (200) is converted into a dot pattern for display by a color printer (212). The image (200) is separated into Cyan, Magenta and Yellow color planes (202, 204, 206); a dither matrix (208) is applied to the Cyan plane (202); an inverse (210) of the dither matrix is applied to the Magenta plane (204); and either the dither matrix (208) or the inverse dither matrix (210) is applied to the Yellow plane (206). Fast green/magenta dithering can be obtained. <IMAGE>
