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.
