Stereoscopic displays are becoming very popular since more and more contents are now available. As an extension, auto-stereoscopic screens allow several users to watch stereoscopic images without wearing any glasses. For the moment, synthetized content are the easiest solutions to provide, in real-time, all the multiple input images required by such kind of technology. However, live videos are a very important issue in some fields like augmented reality applications, but remain difficult to be applied on auto-stereoscopic displays. In this paper, we present a system based on a depth camera and a color camera that are combined to produce the multiple input images in real-time. The result of this approach can be easily used with any kind of auto-stereoscopic screen.
