In FIG. 31, the left side is the image 21P captured by the camera 21 of the partner station, and the right side is the partner station image 12P on the monitor 12 of the own station. At time (a), the partner station camera image 21P and the partner station image 12P of the own station are the same. Here, it is considered that the partner camera is controlled so that the position of the person of the partner station on the screen is centered in the partner station image 12P of the partner station. When the electric camera 21 of the terminal of the partner station is controlled from the remote controller 14 of the own station, the camera image 21P of the partner station is displayed at time (b).
Then, although the person is a little closer to the right side, the same state as at the time (a) occurs in the partner station image 12P of the own station. this is,
This is because there is a time delay for transmission because the image is transmitted after being compressed. At time (c), the partner station image 12P of the own station is finally moving to the right.
However, in the partner station camera image 21P, the person is already in the center of the screen. At time (d), the position of the person of the partner station on the screen of the partner station image 12P of the own station comes to the center, so the operation of the remote controller 14 is stopped. However, at this time, the person has already approached the right side in the camera image 21P of the partner station. Therefore, at time (e), the person of the partner station shifts to the right side in the partner station image 12P of the own station, even though the operation of the remote controller 14 has already been stopped.

In step 411, the electric camera 21 of the partner station displays the range requested by the own station by notifying the partner station of the amount of movement or the absolute position. According to FIG. 3, for example, the zoom movement amount and the turntable position data of the electric camera 21 of the partner station are transmitted from the own station to the line corresponding unit 20.
3, transmitted through the demultiplexing unit 202. The zoom movement amount data is transmitted to the camera unit 25 via the controller unit 250 and the camera control signal conversion unit 251, and the camera unit 25 moves only the instructed zoom movement amount from the widest angle position. On the other hand, the turntable position data is A
The digital position signal of the rotary base unit 26 obtained via the / D conversion unit 204 is compared with the comparison unit 253, and the controller unit 250 uses the motor voltage supply unit 2 so that they match each other.
The motor drive voltage is supplied to the rotary base 26 via 54,
The orientation of the turntable 26 is controlled. This is Fig. 5 (c), Fig.
This corresponds to the state of 7 (d). Thereafter, in step 412, the control returns to the conventional partner camera control mode.

At step 412, the conventional partner camera control mode is entered. After that, in step 413, when the time period of pressing the "counterpart camera" button is within 1 second, the partner camera control of the present embodiment is finished,
If the time period of pressing the "countercamera" button is 1 second or more, the state returns to step 403.
