As UHDTV displays have become increasingly available in the market, more UHDTV programs are being produced. On the other hand, it has been reported that the perceptual video quality differences between UHDTV and full HD signals are minor in some cases. Consequently, there is an increasing need for UHDTV service references and measurement tools, which can quantify the UHD signals. In this paper, the perceptual image quality of full HD (1080p) and UHD signals is compared along with other formats (720p, 540p, 360p) when they are displayed on a UHD display. We performed subjective tests using a UHDTV display and the subjective scores of the various picture sizes were analyzed.
