A study on scanning methods for a field-sequential stereoscopic display

摘要

This paper focuses on the scanning methods of a field-sequential stereoscopic display system. We examined the advantages and disadvantages of several scanning methods to identify the most suitable one for the field-sequential stereoscopic display technique. An evaluation test using a system with 525 scanning lines and a 120-Hz field frequency was conducted. The results show that the picture quality of the 4:2 or 4:1 interlace method, which maintains high vertical resolution, is superior to that of the simple 2:1 interlace one. We also developed an experimental field-sequential stereoscopic system for HDTV with 1:2 interlacing and confirmed that it is possible to display high-quality stereoscopic HDTV pictures in full 1125-line vertical resolutions.
