Abstract When evaluating extremely high-quality videos that reach maximum human perceptual limits, the conventional perceptual-level evaluation methods may seem insufficient. Hence, a paradigm shift in the evaluation methods is required. In this study, we propose a cognitive-level evaluation method for evaluating high-quality videos using impression strength as an index for the quality of experience (QoE) of an 8K ultra-high-definition television (UHDTV). Based on the evaluation scheme, we quantitatively demonstrated the difference in the quality of high-quality images close to the perceptual limit of human vision, and the results validated the hypothesis of viewers experiencing strong psychological effects when watching 8K videos. In addition, the strength of higher-order impressions such as freshness and deliciousness change with changes in the signal bandwidth and luminance level, indicating that the QoE of a UHDTV can be modulated using signal processing techniques.
