Abstract

The present invention relates to an affine converting apparatus for color graphics processing, wherein image data inputted in various types of color images is converted into coordinates (x, y) and RGB color signals in a pre-processing unit on a frame-by-frame basis, and is 4 × 4 subblocks. 16 AT operators are sequentially input to each of the 16 AT operators connected in parallel, and AT operations are simultaneously performed by 16 AT operators. Image data outputted from the 16 AT operations are respectively set in the operation termination unit. If all of the above conditions, the end signal is generated into 16 buffers, and the image data of the sub-blocks stored in the 16 buffers is finally outputted, so that the color graphics processing for the animated landscape can be processed at high speed.
