Abstract
In this research, we improve image resolutio of our spherical immersive display by using HDTV system. By using a HDTV projector and a HD camera unit, the system has approximately 3-times higher resolution than NTSC based spherical immersive display theoretically. Also the aspect ratio of HDTV (16:9) enhances the effective pixel ratio of original images that captured by the camera unit. We made a prototype system. We evaluated the effectiveness of this method by measuring subject's eyesight. As a result, we verified resolution enhancement with this system.
