    • A camera controlling apparatus for a television conference system wherein the turning speed of a camera is varied in response to an operation mode. The camera controlling apparatus includes a preset control section for outputting a preset control signal for moving the camera at a first turning speed to a predetermined point, and a self room manual control section for outputting a self room manual control signal for moving the camera at a second turning speed lower than the first turning speed. The camera controlling apparatus further includes a reception manual control section for outputting a reception manual control signal for moving the camera at a third turning speed lower than the second turning speed in response to a manual signal transmitted thereto by way of a communication line. Any of the control signals is inputted to a speed control section, and the camera is controlled to be turned at a turning speed represented by the thus inputted control signal by the speed control section.
    • 一种用于电视会议系统的相机控制装置,其中相机的转动速度响应于操作模式而变化。 相机控制装置包括:预设控制部分,用于输出用于将照相机以第一转动速度移动到预定点的预设控制信号;以及自动室手动控制部分,用于输出用于在相机处移动相机的自室手动控制信号 第二转速低于第一转速。 相机控制装置还包括接收手动控制部分,用于响应于通过通信线路发送到其的手动信号,以低于第二转动速度的第三转向速度输出用于移动照相机的接收手动控制信号。 任何控制信号被输入到速度控制部分,并且通过速度控制部分控制照相机以由这样输入的控制信号表示的转动速度转动。
