Paper Abstract

It is a widely held belief that in the long run, three-dimensional (3D) display should supply stereo to multiple viewers without wearing any viewing aids and free to move. Over the last few decades, great e®orts have been made to approach auto-stereoscopic (AS) display for multiple viewers. Spatial multiplexing technique has ¯rst been employed to accommodate multiple viewers simultaneously in stereoscopic planar display. However, resolution of each view image decreases as the number of viewers increases. Recent development of high-speed liquid crystal display (LCD), which is capable of operating 240-Hz frame rate, makes feasible multi-viewer display via time multiplexing and improving image quality at the same time. In this paper, we propose a display adjustment algorithm that enables high-quality auto-stereoscopic display for multiple viewers. The proposed method relies on spatio-temporal parallax barrier to channel desired stereo pair to corresponding viewers according to their locations. We subsequently conduct simulations that demonstrate the e®ectiveness of the proposed method.
