| Research Abstract |
The aim of this research was to visualize and model the responses on visual perception and biological signals while we watching video images. As a response of visual perception, we obtained a result that the changes of gradation of perceived brightness affected the differential limens and influenced for an appearance around a visual target in the image. We measured the biological signals while watching the video image that was displayed on 3D/2D display or portable device screen. We analyzed the signals by the method based on the independent component analysis(ICA). The method had high sensibility for the temporal change of the presence for a scene in the movie video. We approached the modeling of responses on visual perception and biological signals by using the method of ICA, and verified.
