13.2: Review of Subjective evaluation method of high‐quality TV images

Abstract

Vision is the most direct and effective way for humans to obtain information from the outside world. More than 80% of the information is transmitted to the brain through eyes. With the development of display technology, the picture received by the eyes is brighter, more vivid and clear. For such high‐quality display images, the objective evaluation system is slightly insufficient. Merely describing the image quality with parameters such as brightness, color gamut, and contrast is not completely consistent with consumers' real feelings. Therefore, subjective evaluation based on human vision is necessary to add to the image quality evaluation system. This article focuses on the domestic and international standards of subjective assessment methods for image quality, and reviews it from the perspectives of viewing conditions, observers, test preparation, test methods, and result analysis. Based on the above research, a subjective evaluation method suitable for high‐quality display devices is summarized.
