Description of the Related Art A video conference system is a system that enables a conference between a plurality of persons at remote locations by connecting two or more points with a communication line and transmitting video and audio to each other in real time. The terminal device of this video conference system is basically a television / camera for shooting, a microphone for voice input, a monitor for displaying captured video and received video, a speaker for outputting received audio, video information and audio information. It is composed of transmitting and receiving devices such as the above, and these control devices, and is installed for each conference participant.

て見られたくない部分についてもカメラの撮影視野内に
入り送信されてしまうことがあった。However, in such a conventional example, the receiving side can control over the entire physical movable range of the camera motor base on the transmitting side, and the portion which the receiving side does not want to see. Also, there was a case where it was transmitted within the field of view of the camera.
【0005】本発明は、このような不都合を解消したテ
レビ会議用端末装置を提示することを目的とする。It is an object of the present invention to present a video conference terminal device which eliminates such inconvenience.

【課題を解決するための手段】本発明に係るテレビ会議
用端末装置は、撮影カメラの設定された撮影範囲の中
で、当該撮影カメラを、通信相手からの制御信号により
遠隔制御する制御手段を具備することを特徴とする。A video conference terminal device according to the present invention comprises a control means for remotely controlling a photographing camera in a photographing range set by the photographing camera by a control signal from a communication partner. It is characterized by having.

【作用】上記手段により、映像受信側からの遠隔操作に
よっても、上記制御手段は、映像送信側が送信したくな
いと思う映像を撮影するようには撮影カメラの向きや倍
率などを制御しない。これにより、不都合のある映像が
送信されてしまうことを防げる。With the above-mentioned means, the control means does not control the direction and magnification of the photographing camera so as to photograph the image which the image transmitting side does not want to transmit even by the remote operation from the image receiving side. This prevents inconvenient video from being transmitted.
