ABSTRACT:
A viewing apparatus for use in providing either a three-dimensional image when used to view a side-by-side display on a conventional video screen of related left and right images that are each horizontally compressed, or alternatively for use in providing a wide-angle image when used to view a single horizontally compressed image displayed on a conventional video screen. In providing the three-dimensional image, the apparatus transmits the displayed left image to the viewer's left eye and the displayed right image to the viewer's right eye, while horizontally expanding the compressed images and returning them to their original, natural porportions. The displayed side-by-side images both extend along the screen's entire vertical length, such that a three-dimensional effect is provided having the same two-dimensional proportions as the conventional video screen. In providing the wide-angle image, the apparatus transmits the single horizontally-compressed image to the viewer's two eyes, while horizontally expanding the image to return it to its original, natural porportions.
