Claims

[Scope of Claim for Utility Model Registration] (1) An image memory that has a storage area corresponding to each picture element on a CRT and stores color images to be displayed on the CRT, and synchronization with scanning of the beam of the CRT from the image memory. a color image output means for outputting a color image for each picture element; a color setting means; and a color image output means for outputting a color image for each picture element; 1. A color image display device, comprising means for making the signal larger or smaller than others, and a CRT drive section that receives each primary color signal and drives a CRT picture tube. (2) When the color image output means separates and outputs a color image into three primary colors for each pixel, it is characterized by comprising an identification circuit that identifies the color of each pixel using the three primary color signals. A color image display device according to claim 1 of the utility model registration claim.
