Abstract
It was recently shown that a high-speed optoelectronic display, via a novel signal processing technique called temporal psychovisual modulation (TPVM), can exhibit stereoscopic images to viewers wearing 3-D glasses and clean 2-D images to those without glasses all at the same time. This research aims to improve the above backward-compatible stereoscopy method by adjusting the backlight of today's common LED-lit liquid crystal display systems. Visual quality of the system can be enhanced by jointly optimizing the backlight intensity and the image signal at a negligible extra computational cost. For real-time applications of low-cost consumer electronics, this work also provides a low-complexity solution of backward-compatible stereoscopic display, in which highest 3-D quality is ensured with a small compromise of the 2-D quality.
