A digital photo frame (DPF) has evolved from a tool for displaying favorite photographs to a device that displays videos. The next advancement is the introduction of the stereoscopic display. Although a DPF with a stereoscopic display has already been released on the market, it only enables horizontal parallax. In this paper, we describe a different type of 3D display system based on a DPF and a fly's eye lens, both of which are commercially available. Our system enables not only horizontal but also vertical parallax because integral photography (IP) is used. IP was thought to be a technology of the future because a very high resolution LCD and a dedicated fly's eye lens were believed to be necessary. However, the extended fractional view (EFV) method[1] proposed by one of the authors enabled freely combining a wide range of LCDs and the relatively inexpensive fly's eye lenses available on the market to produce IP. It greatly contributed to the initial cost reduction. This new system uses the EFV method. The main problem is how to supply good content. Therefore, we also developed a method of producing the animation of IP by using CG technology.
A new moving integral imaging system was developed. 3D CG animation data are rendered from multiple viewpoints and integrated into a video sequence with our method. The sequence is displayed on a laptop LCD and observed through a generalpurpose fly's eye lens. A stereoscopic view with full parallax was obtained.
