Abstract

In these days, Integral Photography has been extensively studies. As a major problem of IP, there is a problem that the depth of the displayed 3D image is reversed from the original object. As a method to solve this problem, there is a method using a concave lens array for recording and using a convex lens array for display. However, in this method, there is a large difference between the incident angle of light ray incident on the lens at the time of recording and the display angle of the light ray emitted from the lens at the time of display. So, in this research, we proposed a photographing method of IP with high angle reproducibility of light rays by using convex mirror array for recording. From the analysis on the optical path of the light ray incident on each convex mirror, it was revealed that the proposed method has higher angle reproducibility of light rays than the conventional method. In the experiment comparing 3D images displayed by the proposed method and the conventional method, it was confirmed that the image displayed by the proposed method has larger parallax according to the movement of the observer than that of the conventional method.
