Abstract

Recently, International Telecommunication Union approved several methods for objective video quality measurements to be included in international standards. These methods are mainly developed to measure quality of digital video on professional CRT monitors. In this paper, we performed subjective tests in order to examine the applicability of the standard quality assessment methods for different display monitors such as common CRT, PDP, and LCD TV monitors as well as professional CRT monitors. Subjective testing on different display monitors shows that there exist relatively high correlations between the various display monitors, which indicates the standard quality assessment methods can be used on the display monitors under the given conditions of subjective duality assessment.

최근 국제전기통신연합은 몇몇 객관적 화질평가 모델을 국제 표준으로 채택하였다. 채택된 화질평가 모델은 방송용 CRT 모니터를 통해 출력되는 디지털 비디오의 품질을 측정하는데 적합하도록 개발되었다. 본 논문에서는 객관적 품질평가 모델이 방송용 CRT 뿐만 아니라 일반적인 CRT, PDP, LCD 등의 디스플레이 기기에 적용이 가능한지 검토하기 위하여 주관적 실험을 시행하였다. 다양한 디스플레이 기기를 대상으로 주관적 품질평가를 시행한 결과 각각의 디스플레이 기기 사이에 비교적 높은 상관관계가 존재하였다. 이는 표준으로 채택된 화질평가 모델이 주어진 주관적 평가 조건하에서 각각의 디스플레이 기기에 적용될 수 있다는 것을 보여준다.
