Abstract
Integral Photography (IP) is one ideal way to create three-dimensional (3 D) autostereoscopic images, because a 3 D autostereoscopic image can be seen from desired viewpoint without the aid of special viewing glasses. We have already proposed the IP method using a micro lens array and an HDTV camera to offer 3 D autostereoscopic images of moving objects in real time. But there are two problems yet to be resolved. One is pseudoscopic images that show reversed depth representation. The other is interference between the element images that constitute a 3 D autostereoscopic image. In this paper, we describe a new IP method with a lens array consisting of gradient-index lenses designed to conquer these two problems. Experimental results indicating the advantages of this method are shown. These results suggest the possibility of using gradient-index lenses for the IP method.
