Abstract
Abstract An integral, autostereoscopic three-dimensional image suitable for lenticular display is generated from a plurality of image perspectives by interpolating additional images from hypothetical perspectives, as follows. Initially, actual image signals are generated from a plurality of actual images obtained from a plurality of actual image perspectives. The additional images are obtained by operating upon the actual image signals and forming interpolated image signals from hypothetical image perspectives. Finally, an integral three-dimensional image is generated from the combination of images obtained from the actual image perspectives and the hypothetical image perspectives, and is suitably displayed. According to one suitable display, the integral image may be exposed upon a photosensitive sheet that is attached to a lenticular faceplate for subsequent viewing.
