First Claim
Patent Images
1. Apparatus adapted to be disposed in front of a picture for enhancing the depth thereof comprising:
- means defining a framing aperture aligned generally parallel with a picture to be viewed and spaced away therefrom, the outer dimensions of said means being larger than the picture to be viewed, the inner dimensions of said framing aperture being smaller than the picture to be viewed to conceal the edges thereof, whereby the distance to the picture is difficult to judge, and whereby different amounts of each edge of the picture are seen by each eye of a viewer, thereby suppressing the clues to flatness of the picture and enhancing the clues to depth thereof.

Abstract
Embodiments of an apparatus and design principles for its operation have been devised such that when these embodiments are placed at the screen of a television set (preferably color) or at a movie screen or at an appropriate photograph, a highly noticeable observation of depth is produced. This is done without apparatus at the eyes and without using multiple images as in stereoscopy.
