Abstract

Current 3-dimensional display system using only the binocular disparity has the problem of the conflict between eye convergence and accommodation. A 3-dimensional display system for one observer that can solve it was introduced in this paper. A proof about the possibility of the satisfaction of accommodation of one eye was given as the experimental result in this 3-dimensional display system. This system uses 2- dimensional images to generate a 3-dimensional image for one observer. The number of 2-dimensional images is 127 for one 3- dimensional image. The horizontal directional motion parallax is possible in this system but the area is a little larger than the distance between both eyes of one observer. This system is close to the observer and generates horizontal parallax only 3-dimensional image. In this case, vertical diffuser could not be used in the system because of image blurring in vertical direction. A vertical directional cylindrical lens instead of the vertical diffuser was used in the system. It could solve the image blurring but the depth directional freedom to the observer's eye position was restricted in narrow width because of using cylindrical lens. This system can offer a large 3-dimensional image as HMD (Head Mounted Display) can display a large 2-dimensional image.
