Low resolution and narrow viewing angle are common problems for most of the existing autostereoscopic display systems. Although integral imaging is among the promising candidates for future autostereoscopic display, it is not yet free from the above bottlenecks. In this paper, a new technique to enhance the picture quality of a three-dimensional image using an offset lens array is proposed. The proposed system is suitable to realize a tiled integral floating display with high pixel density, while it also increases the viewing angle to match all of the optical devices in a single display unit. The proposed scheme was also verified with experimental results.
