When any observer in the audience, viewing either a television or a motion picture by our invention, receives an image of a given scene having the same relative size, shape and location on the retina of each of his two eyes at any instant and that image of the scene is stationary, the image is flat and resides at infinity. When, however, the image of the scene has some component of horizontal motion in any direction due to either motion of the camera, motion of scene objects (or both), during the acquisition of the moving scene, the image viewed is three dimensional. The reason for this is that if the motion occurs, all scene-object points are proportionally spatially located in playback since all of the original ray angles between camera and scene points are reproduced for both eyes by the ray cross-overs at the scene image points in the same proportionally relative positions as the original object points. The key is to have an identical image on the right and left eye of any given observer at nearly the same instant in time and replace this image by a succession of moving images resulting from a relative horizontal motion of the scene/camera and at a rate consistent with persistence of vision. This moving 3-D imagery occurs because of intersecting rays from successive frames in scene/camera relative motion during playback of the scene images. When the successive frames are presented, the brain cognizes the motion in linking the frames by the persistence of vision. For the brain to perceive an item as moving it must connect these various frames, but because of intersecting rays coming from any given spatial location point in successive frames, the brain cannot connect the frames without also locating the points in space. Therefore, our technology presents the scene to the brain in such a way that it can understand the depth information already contained within the image.
