Abstract

To reduce the number of views required for a super multi-view (SMV) display, two or more views are generated with an interval smaller than the pupil diameter, only around a viewer's left and right eyes. The positions of the views are changed referring to the viewer's eye positions to increase viewing freedom. The reduced-view SMV display is implemented using a lenticular-type three-dimensional (3D) display. A cylindrical lens constituting a lenticular lens projects a group of pixels of a flat-panel display to generate a group of views. The pixel group generating the left view group and that generating the right view group through an identical cylindrical lens are spatially separated to separate the view groups. The left and right pixel groups for different cylindrical lenses are interlaced horizontally on the flat-panel display. A prototype reduced-view SMV display was constructed. Each view group consisted of eight views, and the interval of the views was 2.6 mm. An LCD panel with a slanted subpixel arrangement was used. The screen size was 2.57 in, and the 3D resolution was 256 × 192 pixels. A USB camera was attached to the SMV display to detect the viewer's position. The frame rate of face detection and image updating was 30 Hz.
