Abstract

A system utilizes the camera control server of the CPU to transfer the camera control command, received through the network, to the camera control device to control the camera in order to vary the audio input/output characteristics in linkage with the camera operation and to thereby improve the realistic feeling. In more details, the camera control server also sends control commands to the audio input control device, the audio output device and the video display control device according to the camera control thereby controlling the input characteristics (spreading, direction and sensitivity) of the microphone and the output characteristics (spreading, direction and depth) of the speaker and varying the image displayed on the monitor. The system also includes technology for displaying, on the monitor, the information on the operator of the camera and on the receiver of the image, and for varying the direction of the monitor according to the panning or tilting operation of the camera.

4. A transmission terminal adapted to be connected with a reception terminal including reception means for receiving an image transmitted through a network and control means for controlling the input state of image input means of a partner terminal through the network, comprising:

image input means of which input state is remote controllable;

transmission means for transmitting the image, entered by said image input means, through the network; and

providing means for providing information on the control state of said image input means,

wherein said providing means is adapted to provide identifying information of at least one of an observer of a transmitted image by said transmission means and an operator of said image input means, and

wherein said identifying information represents a login name of said observer.

5. A transmission terminal according to claim 4, wherein said image input means is a video camera.

6. A transmission terminal according to claim 4, wherein the control state of said image input means is the zoom ratio of said video camera.

7. A reception terminal adapted to be connected with a transmission terminal including image input means of which input state is remote controllable and transmission means for transmitting the image, entered by said image input means, through the network, comprising:

reception means for receiving the image transmitted by said transmission means through said network;

control means for remote controlling the input state of said image input means; and

means for receiving and transmitting an operator identifier to enable said transmission terminal to provide identifying information of at least one of an observer of a transmitted image by said transmission means and an operator of said image input means,

wherein said identifying information represents a login name of said observer.

8. A reception terminal according to claim 7, wherein said input means is a video camera.

9. A reception terminal according to claim 7, wherein the control state of said image input means is the zoom ratio of said video camera.

10. An image/sound communication system comprising:
