Integral imaging (II) is one of the promising techniques in the field of autostereoscopic three-dimensional display. Despite of its many advantages, the narrow viewing angle has been a drawback. We propose a technique that enhances the viewing angle of II by resizing the elemental images taken by the pickup process and switching the elemental lenses in the display process. We explain the principle of the proposed technique, analyze the effect on the resolution of the integrated image, and show the experimental results.
