Scanning method for field-sequential stereoscopic display

Abstract

The past few years have seen greater efforts on the development of a three-dimensional television. The field-sequential stereoscopic display, which shows the right-eye and left-eye images alternately, is one of the most promising stereoscopic television systems at the moment. This study focuses on the scanning of field-sequential stereoscopic pictures-we examined picture quality and conducted an evaluation test using a system with 525 scanning lines and 120Hz field frequency. The results show that the 4 : 2 or 4 : 1 interlace method, which maintains high vertical resolution, is superior to simple 2 : 1 interlace in the quality of pictures displayed. We also made an experimental field-sequential stereoscopic system for HDTV with 4 : 2 interlace. With this 1125-scanning prototype system, we tested picture quality and confirmed that it is possible to display high-quality stereoscopic HDTV pictures of full 1125-line vertical resolution.
