Previously-produced motion picture films are enhanced for theatrical exhibition, at double the frame rate at which they were originally produced. New images are interpolated between each of the images of the original film. These interpolated images are generated through the use of 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 been produced at double the actual frame rate of production. This enhancement technique can be used selectively for certain scenes or sequences of a motion picture, and not for others. Film or digital projection is suitable. Two-dimensional or three-dimensional motion pictures can be enhanced according to the method described, and motion pictures photographed at high frame rates can be converted to conventional frame rates for general release.
