Outline of Final Research Achievements

This study makes it possible to display images in gradations more than 256 on a large screen. To show the effectiveness of the display in gradations more than 256 that is the number for the present display, we conduct subjective assessments and examine what impressions viewers receive from images displayed in various gradations. Results show that to a certain number of gradation, impressions of the displayed images get better as the number of gradation increases and that this tendency is conspicuous when images includes more gradation areas such as human skin and the sky. These results are useful for development of image displays in the near future.
