A Multidimensional Evaluation of the Perceptual Quality of Television Sets

This paper discusses the relative importance of various perceptual attributes in overall perceived picture quality while using some current television sets. The experiments included six 28-in. television sets varying in spatial resolution, color reproduction, peak luminance, and luminance contrast. Observers were asked to judge 15 perceptual attributes on the television sets using a 10-point categorical scale. Multidimensional scaling procedures were applied to the data in order to find clusters of attributes and to obtain a graphical representation of the results. — Relating to the physical changes as applied in this experiment, it was found that color rendering was the most important factor in the comparison, favoring a more reddish color setting, followed by perceived sharpness. When subjects do not like the color rendition of a television set, other differences between the sets are not considered relevant by them unless these differences are substantial. Thus, the relationships between average scores found for the quality-related attributes and physical quantities as measured on the television sets were influenced by perceived color differences between the sets.
