Title: Projection apparatus for stereoscopic pictures

Abstract: In the illustrative embodiments of the invention disclosed, autostereoscopic pictures are produced by projecting a series of two-dimensional views of an object field onto a lenticular screen. Substantially uninterrupted and non-overlapping condensed, or lineiform, images of the two-dimensional views are formed beneath each lenticule of the lenticular screen by setting the number M of these images in the image band beneath each lenticule, and hence the total number of two-dimensional views projected, equal to w/m, where w is the lenticule width and m is the width of each condensed image. In order to project the required number M of two-dimensional views while avoiding gaps between adjacent condensed images, the projection lenses and the associated film frames are positioned along a plurality of adjacent, parallel, straight lines in a manner such that the apertures of the lenses are effectively in edge-to-edge contiguous relation.
