An autostereoscopic system is described which permits the observation of a high-resolution image by several persons simultaneously and is suited to mass production. The display uses cylindrical lenses positioned in front of an image output screen. The number of lenses, or the parallax number, determines the number of simultaneous images which can be used to produce a look-around capability. The playback system uses an electro-optical vertical slit which oscillates horizontally within a large horizontal convex cylindrical lens. The resolution of the method is excellent and the parallax number can be varied. Using the transmission band width of HDTV, a five parallax color system with the standard television resolution can be produced.
