Disclosed is a device for rapidly quantizing colored images for the raster type of graphics devices as illustrated in the figure. The device creates "multiple look-up tables" so that the errors caused by the color quantization may cancel out each other and refers these multiple look-up tables by turns or randomly in loading the images into the display buffer.
