Outline of Final Research Achievements

As a method of time series evaluation of 3D’s contents, the pinch power method was useful. Among evaluation words, “overwhelm” played an important role. As key components of 3D movie to affect human cognition, the effect of 3D became larger when the angle of view was small and ratio of visual object in the display was large.
Functional MRI experiments elucidate that 3D stimuli-specific brain activity is appeared. The specific brain activity after viewing 3D movie suggested some kind of fatigue in the brain. The visual fatigue esitimated by eye lens accomodative activity was detected on the condition of binocular disparity of over 2 degrees in 3D movie.
The reality of 3D movie is due to 3D qualities such as a depth sensitivity. 3D recipe has been desgined with optical components defined by binocular and motion parallax etc. It is confirmed that depth map creation from motion and compositional information is able to produce more natural 3D image with sufficient accuracy.
