ABSTRACT:
The present invention relates to an image processing system for afterimage reduction for suitable use in a stereoscopic television apparatus. This system has been devised in consideration of the fact that the afterimage in a TV camera image to be displayed is most influenced by a frame image previous to the image to be displayed. The afterimage can be reduced by performing a novel algorism operation on each pixel value. Pixel values of a right image stored in a second input frame memory, which has been output from the TV camera prior to a left image to be displayed which is supplied from an input selector, is multiplied by a predetermined coefficient. The multiplied value is subtracted from pixel values of the left image to be displayed. Thus, a left image to be displayed, which has been subjected to afterimage reduction processing, is produced, and stored in a first output frame memory. Similarly, a right image to be displayed, which has been subjected to afterimage reduction processing, is produced.
