ABSTRACT:
The method for evaluating a quality of an image on a display device displays a test pattern having different contrast intensities on a display screen of the display, then determines a contrast intensity at which the test pattern is visually discernible and uses the thus determined contrast intensity as a value for evaluation of granularity on the display device. The method is optimal for achieving quantitative and objective visual evaluation of image quality, particularly, its granularity.
