Abstract
In order to reduce the resolution of a flat-panel display used for the super multi-view (SMV) display, we previously proposed a reduced-view SMV display that generates views only around a viewer's left and right eyes. A face-tracking system with one camera was combined with the reduced-view SMV display to enlarge the viewing freedom. However, the viewing freedom in the depth direction was limited. In the present study, we propose a SMV display system which generates views corresponding to three-dimensional (3D) positions of the viewer's eyes to enlarge the viewing freedom in both the horizontal and depth directions. An eye-tracking system with a stereo camera is combined with the previously developed reduced-view SMV display. Pixels on the flat-panel display that are seen through each cylindrical lens are determined geometrically for all of the cylindrical lenses. Parallax images are generated corresponding to the 3D positions of the viewer's eyes. To achieve the SMV display condition, two or more consecutive pixels including the determined pixels are used to display the parallax images. The enlargement of the viewing freedom was confirmed by the experiments.
