Previously-produced motion pictures are enhanced for theatrical exhibition, at double the frame rate at which they were originally produced. New, rendered images are interpolated between each of the images of the original motion picture. For image pixels containing excessively complex motion, those pixels are corrected to eliminate such complexity. This correction is accomplished by selecting the specific pixels that are too complex to be made a part of a synthesized image, rejecting them, and repeating only those appropriate pixels as they appeared in the previous frame; and by treating all other pixels in other images in a normal manner, known in the art. The pictures are projected through digital means at 48 frames-per-second. The invention allows for upgrade of previously-produced motion pictures for high-frame-rate presentation without repeating any frames, improving the quality of presentation by eliminating any appearance consistent with low-frame-rate photography and presentation.
