Abstract

PURPOSE:To facilitate the tracing operation by using a light pen or the like so as to designate a desired area on a display device pieced up by a video camera with zoom lens fitted to a universal head thereby adjusting the direction of a camera and zooming automatically. CONSTITUTION:The video camera 1 with a zoom lens 3 is fitted to the universal head 5. An output of the video camera 1 is sent to the display device 7, on which a picture is displayed. An address point-out means 9 such as a light pen or a mouse points out a desired area on the screen 7. A CPU 11 calculates the address of the area designated by the light pen 9 or the like to obtain the direction of the universal head thereby directing the camera 1 into the direction, controlling the zooming of the zoom lens 3 and adjusting a picture angle A. Thus, the tracing operation of the camera is automated.

Prior Art Conventionally, as shown in Fig. 9, a video camera (1) is connected to a monitor television, that is, a display (7), the camera is placed on a rotating stand (5), and this rotating stand is connected to a manual remote control switch (4n). Move the es to determine the direction of the camera (1), and move the camera's zoom lens and e(3) with the manual remote control switch 01 to determine the angle of view. These switches are operated by the operator while looking at the screen. The goal was achieved by repeatedly turning the switch on and off until the desired angle of view was obtained.However, this was a rather complicated operation.
There was a strong desire for its change.
