Abstract
The number of 2D views available to form an autostereoscopic 3D image is increased by using a beam combiner with two displays. Each display may comprise sequentially illuminatable light sources imaged by converging lenses for illuminating sequentially reproduced 2D images in spatial light modulators. The views are combined by the beam combiner so as to be visible to an observer in different directions corresponding to the directions from which the views were recorded during image capture.
