Abstract
Recently, TVs with a wide field of view, high spatial resolution, and 8k ultra high-definition have started test broadcasting in Japan. People who viewed the test broadcasting programs often commented that they felt rich depth perception from 8k scenes. Rich depth perceptions from two-dimensional 8k broadcasting have not been confirmed experimentally. Here, we identified 8k UHDTV scenes in which viewers perceive rich depth perception by conducting an experiment with continuous subjective evaluation of depth perception. Then we measured viewers' accommodation with wavefront sensors and demonstrated that accommodation responses were induced by some 8k UHDTV scenes providing objective evidence for viewers feeling rich depth perception from two-dimensional 8k UHDTV images. We successfully confirmed experimentally that rich depth perception can exist while viewing two-dimensional 8k UHDTV scenes and demonstrated that high quality motion parallax relies on monocular depth cues for perceiving rich depth sensations.
