Abstract

The invention is a method and apparatus for generating an autostereo image. The apparatus comprises at least one light source generating at least two views of an image, a parallax or "slit"-type barrier screen and at least one light-transmitting elements projecting the at least two different views provided by the light source at one or more apertures in the barrier screen. A viewer viewing the screen perceives an autostereo image as a result of the left and right eyes of the viewer seeing different views of the image. In one embodiment, the light source comprises at least one digital projector. In one embodiment, the light-transmitting elements comprise fiber optic strands. A first end of the strand is arranged to receive light projected by one of the light sources. A second end of the strand is arranged to project at a rear side of the barrier screen.
