Autostereoscopic viewing device for creating three-dimensional perception of images
First Claim
1. Television apparatus for creating a three dimensional image of pictures from television images, said television apparatus comprising:
- image screen means for displaying a plurality of visually distinct image segments containing three dimensional information on parallelly disposed elongated strips having substantially mutually parallel longitudinal axes;
lens means for being relatively positioned adjacent said image screen means, said lens means used for viewing said image segments therethrough;
said lens means defining an axis;
said axis of said lens means having a first end, a second end and a center;
said lens means comprising a plurality of lens segments for being in registration with said image segments, each said lens segment defining at least one curved surface;
said lens segments each having a longitudinal axis that is generally perpendicular to said axis of said lens means and generally parallel to the longitudinal axes of said elongated strips;
said lens segments each being juxtaposed adjacent to at least one other said lens segment;
said lens segments each defining a maximum thickness;
said maximum thickness of each said lens segment being measured in a direction that is generally orthogonal to both said axis of said lens means and said longitudinal axis of said lens segment; and
said maximum thickness of each consecutive lens segment from said center of said axis of said lens means of each said lens segment;
increasing in the direction from said center of said axis of said lens means to said first end of said axis of said lens means; and
increasing in the direction from said center of said axis of said lens means to said second end of said axis of said lens means.

Abstract
An autostereoscopic viewing device with a flat picture screen and a pattern of cylindrical lens portions for producing three dimensional image perceptions without the need for additional optical accessories. The viewing device provides the largest possible freedom of movement of the viewer, whereby the reproduction quality is as uniform as possible and out of focus, cross-talk and other disadvantageous optical effect are greatly reduced. The procedures for making any necessary optical corrections are based on the plane parallel changeable positioning of a flat picture screen relative to an array of cylindrical lens portions. The array of cylindrical lens portions has an increasing thickness as well as a decreasing pitch width when moving from the middle to the vertical side edges. The pixel, or picture strip, size on the picture screen is a constant.
