Real-time integral photography using extended fractional view method

We developed a new system to capture, synthesize, and display moving integral photography in real time using the extended fractional view (EFV) method [1]. Though most stereoscopic display systems currently used in movie theaters require special glasses, there are autostereoscopic systems in which such glasses are unnecessary. Among them, integral photography (IP) is one of the best because not only horizontal but also vertical parallax can be obtained. Unfortunately, the use of IP is not widespread, probably because the fly's eye lens has to be custom-made, at enormous expense, in accordance with the dot pitch of the LCD. However, inexpensive custom-made fly's eye lenses can be combined with various LCDs of different resolutions by using the EFV method. Another advantage of the EFV method is that relatively low-resolution LCDs can be used because the direction of the ray becomes pseudo-random and a space can be covered with a smaller number of rays.
