Recently; even though the use of high-gradation display devices in medical and other specialized fields has become essential; most devices in general field usage are still typically 8 bits luminance level displays. However; since it can be presumed that image quality improves when high-gradation display devices are used; we investigated the results obtained by increasing luminance gradation levels and found that image impressions improved as the number increased. In addition; the results indicated that the impression improvement peaked at just less than 9 bits.
