Experimental Study on Camera Setting for Tele-communication Environment with Tiled Display Wall

To realize ultra-realistic tele-communication via the Internet, we consider that displaying of the video with the large-scale screen in remote sites by transmission of ultra quality video streaming is effective. In past research, we have constructed tele-immersive environment with tiled display wall to realize high-realistic tele-communication. However, the video image captured by a single small camera is difficult to display as video streaming with realistic high-resolution on tiled display wall, because there is a limit in the display resolution of video image captured by a single camera. In response to these issues, we have constructed the tele-communication environment to display a ultra-resolution video image on tiled display wall by multi-transmitting each video which captured by four cameras with tiled display wall. However, the adjustment of each camera position is necessary to display a high-resolution video by combination of boundary area between each captured video, the effective camera setting is not make clear. In this paper, we have conducted experimental study the effect of position setting of multiple cameras on a high-resolution video in telecommunication environment with tiled display wall.
