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. These new images are generated by computer software that analyzes the actual horizontal and vertical displacement of each pixel of every image of the original motion picture, so the interpolated images accurately depict the exact image that would have been captured, if the original motion picture had originally been produced at double the actual frame rate of production. This enhancement technique can be used for an entire motion picture, or selectively for certain scenes or sequences. For image components containing complex motion, those components are selected for treatment to correct for such complexity. The entire process can be executed automatically. In the preferred embodiment, the pictures are projected through digital means at 48 frames-per-second.
