Paper Abstract

In order to identify the conditions which make stereoscopic images easier to view, we analyzed the psychological effects using a stereoscopic HDTV system, and examined the relationship between this analysis and the parallax distribution patterns. First, we evaluated the impression of 3-D pictures of the standard 3-D test chart and past 3-D video programs using some evaluation terms. Two factors were thus extracted, the first related to the sense of presence and the second related to ease of viewing. Secondly, we applied principal component analysis to the parallax distribution of the stereoscopic images used in the subjective evaluation tests, in order to extract the features of the parallax distribution, then we examined the relationship between the factors and the features of the parallax distribution. The results indicated that the features of the parallax distribution are strongly related to ease of viewing, and for ease of viewing 3-D images, the upper part of the screen should be located further away from the viewer with less parallax irregularity, and the entire image should be positioned at the back.
