An image processing circuit comprising thresholding limiters and constrained smoothing filters splits a source image into two images, which, when projected overlaid on a projection surface by {HEAD ~ a pair} of {TAIL ~ double stacked projectors}, together form an image essentially identical to the source image, but where one image has significantly less high frequency components
