국문 초록

In this paper, we analyze the effect of camera panning to the visual discomfort in 4k-UHD contents. UHD is now widely spread but still suffers from the time and coast in contents creation due to vast amount of file size. In another aspect, UHD may yield the visual fatigue caused by objects or frames moving in the large screen. To investigate the visual discomfort in the presence of camera panning, subjective evaluation is conducted using video clips that are created considering the distance between the camera, characters and background. Subjective scores illustrate that the effect of camera panning is strongly correlated with the camera panning speed, and weakly related to the distance among three elements. From the subjective test, we conclude that visual discomfort occurs when the object moves at a speed over 2560 pixels per second, or 43 pixels per frame in 4K UHD contents, and 96 cm per second, or 1.6 cm per frame in a 65 inch monitor.
