Abstract
First, we evaluate the impression of 3D HDTV images using some adjectives, and divide the adjectives into groups according to the correlations among them. We pick up two factors [sense of presence][ease of viewing] representing the groups. Secondly, we apply principal component analysis to the parallax distribution of the stereoscopic images used in the former subjective evaluation tests, in order to extract the features of the parallax distribution. Finally, we examine the correlations between factors and the features of the parallax distribution. As a result, the features of the parallax distribution have a strong correlation with ease of viewing and have no correlation with sense of presence.
