摘要：In recent years, television systems with a wide field of view that offer an elevated sense of presence have been proposed. They have higher spatial resolutions than conventional systems. On the other hand, the effects of increasing the temporal resolution or frame rate of television systems have not yet been sufficiently investigated, with the exception of the effects of frame interpolation at the receiver. On the assumption that people will enjoy TV with wide field of view displays at home in the future, we conducted a quantitative analysis of the effects of increased frame rate by a subjective evaluation of moving picture quality. The results indicated that an increase in frame rate from 60 frames per second (fps) to 120 fps improved the evaluated quality by 0.46 rank and an increase from 120 to 240 fps improved quality by 0.23 rank, with statistical significance. The degree of improvement depended on the picture content.
