Abstract
A color image processing system comprises a plurality of color image data generators each for generating color image data for different colors and a plurality of memories each for storing the color image data generated for each color by one of the color image data generators. A writing control device independently controls the speed at which color image data is written into respective ones of the plurality of memories. This control device includes an address counter for determining writing addresses of respective ones of the plurality of memories, a clock pulse generator, and a clock pulse control device for variably controlling the number of clock pulses supplied to the first address counter for determining the rate at which the writing addresses are determined. A read out device reads out the color image data stored in each of the memories and a recording device records the color image data for each color in response to output from the read out device. This color image processing system permits accurate registration of images reproduced on a single medium in each of the plurality of colors by independently adjusting the magnification of an image reproduced in each respective colo…
