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