ABSTRACT:
A pan head control system for automatically panning and tilting a TV camera so that the aim of the TV camera is moved along a desired path on an object includes a pan head which supports a TV camera and is provided with a driving mechanism which drives the pan head to pan and/or tilt the TV camera under the control of a controller. A monitor TV is connected to the TV camera and projects an image taken by the TV camera on a screen. A plurality of points on the object through which the aim of the TV camera is to be passed are designated by touching a light pen at the images of the points on the image of the object projected on the screen of the monitor TV. The coordinates of the designated points on the screen are determined, stored and displayed on the screen of the monitor TV. A continuous trajectory line is plotted by properly joining the designated points on the screen of the monitor TV. Data on a plurality of points on the trajectory line are stored at predetermined intervals, and read out in order. The controller controls the driving mechanism to pan and tilt the TV camera so that the images of the points represented by the data read out are positioned at the center of the screen in order.
