Abstract
In this paper, we compared image qualities of movies displayed on an LCD (liquid crystal display) and a PDP (plasma display panel) by conducting a subjective experiment and measuring physical properties measurements of the displays. We prepared sixteen movies with different dynamic range, saturation, contrast and colorfulness, and 42 observers rated the quality of the movies. We also measured the displaysf physical properties such as the luminance, chromaticity. We analyzed the relationship between the observersf ratings and the measured physical properties and found that the distribution of the luminance histogram is an important factor that affects the observersf reactions to the movies.
