PURPOSE:To automatically correct the camera position in the reverse direction by calculating the encoding delay when a camera stop direction is accepted and calculating the stopped camera position. CONSTITUTION:When the camera position is controlled when performing the picture communication in real time, the picture on a monitor screen by the encoding delay and the camera position in the field are deviated. In this case, for example, the storage amount of a transmission buffer 5 is monitored by a transmission buffer monitoring part 6. By performing subtraction by the transmission rate of the transmission data, the delay time in the transmission buffer 5 is calculated. By adding the arithmetic delay in an encoding part 4, the encoding delay time is calculated by an encoding delay calculation part 7. A camera control part 8 moves and stops the camera by the camera control direction signal from an opposite side 2. The moved amount of the camera is calculated in the delay time from the encoding delay time from the part 7 and the camera movement speed and the camera is moved in the opposite direction. |
