Display. Special Contribution from IDW '97. Scanning Method for a Field-sequential Stereoscopic Display

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 a 120 Hz field frequency. The results show that in the quality of pictures displayed, the 4 : 2 or 4 : 1 interlace method, which maintains high vertical resolution, is superior to the simple 2 : 1 interlace one. We also made an experimental field-sequential stereoscopic system for a HDTV with a 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 resolutions.
