Abstract: The reproduction device of the invention can be used, for instance, for work station structures for an active person with autostereoscopic vision and several passive monoscopically viewing observers and large-scale presentation structures. This reproduction device generates in the filed of observation two large, undistorted mono-regions, between which there is a stereo region. On the transition from the stereo region to one of the two mono-regions, the observer sees monoscopically immediately without any pseudoscopic intermediate effects. Mono-stereo compatibility in the stereo region is provided with identical partial images. The convenience for the observer in the stereo region can be further improved by head-tracking.

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.
