Abstract
The invention provides a multi-site television conference system which provide natural video images and acoustic images which provide a good feeling of presence to participants who participate in a conference through respective conference terminals. A plurality of cameras are connected to each of conference terminals located at different sites remote from each other and pick up video images of a participant who uses the conference terminal. A central control unit receives, at a multi-site image inputting section thereof, from the conference terminals, video images of participants of the respective conference terminals picked up in multi-directions. An image selection section of the central control unit selects video images of the participants of the conference terminals taking it into consideration how the other conference participants looks to each participant in a virtual conference space and synthesizes the video images into the virtual conference space, and then transmits resulting video images to the conference terminals so that the conference terminals may present computer graphics images to the participants.
