Moving integral photography using a common digital photo frame and fly's eye lens

Abstract

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.

“…Another advantage of EFV is that the quality of auto-stereoscopic images is considerably higher even if relatively low-resolution LCDs are used. Therefore, EFV can be used, for example, for auto-stereoscopic CG animation using digital photo-frames [2] where real-time rendering is not necessary. It has been technologically difficult to apply EFV to real-time interactions, on the other hand, because only very low frame rates could be achieved because numerous computations were required [3].…”

P‐1: Integral Imaging Using Fly's Eye Lens Made With 3D Printer

“…This problem was solved by the emergence of the extended fractional view (EFV) method [1][2][3][4][5], which is an extension of Ishii's fractional view method. Any real number is possible for the number of pixels in each convex lens, meaning that the combination of fly's eye lens and FPD is almost completely unrestricted.…”

“…The EFV method was used. IP images and IP animations displayed on the screen were basically the same as those described in previous papers [1][2][3][4][5].…”

P‐9: Integral Imaging of 3‐D CG Animation Using a Laptop PC and General‐purpose Fly's Eye Lens

“…Integral imaging (II) (or integral photography (IP)) [1]- [8] has long been regarded as ideal for 3D display systems because it can display not only horizontal but also vertical parallax without viewers having to wear special glasses. II is similar to holography in this respect, and yet II can be produced with simple hardware consisting of a fly's eye lens and a common flat panel display as shown in Figure 1.…”

“…Nevertheless, even II was thought to be a technology of the future because a very high-resolution LCD and a very expensive fly's eye lens designed and manufactured in accordance with the dimensions of each LCD was needed. However, the extended fractional view (EFV) method [1][3]- [8] has enabled a wide range of LCDs of common PCs to be freely combined with the relatively inexpensive fly's eye lenses available on the market, thereby producing an IP system. Therefore, the EFV method has made it possible for IP systems to be applied and to become more common earlier than expected.…”
