Abstract

The present invention relates to an affine conversion device for parallel processing of color graphics, wherein image data inputted in various types of color images is converted into coordinates (x, y) and RGB color signals by the preprocessor in units of frames, and is 4 × 4 copies. It is divided into blocks and then sequentially inputted into 16 AT operation units connected in parallel, and AT operation is simultaneously performed in 16 AT operation units, and the AT operation count of 16 AT operation units is counted in a counter, and when the predetermined number is predetermined The end signal is generated from the counter, and the video data of the sub-blocks stored in the 16 buffers is output, so that the color graphics for the animated landscape can be processed at high speed.
