Abstract

We define the image expressible region where three-dimensional (3D) images can be reconstructed in an integral floating display using ray distribution information. Here, the image expressible and viewing regions of the integral floating system, defined using ray distribution based on ray optics, are analyzed to resolve an image-cropping problem known as the viewing window that is due to the virtual aperture. Two experiments for verifying the image expressible and viewing regions are performed, and the results are presented. The obtained analysis is useful to maximize the viewing properties of integral floating.
