Computerized control system for the pan and tilt functions of a motorized camera head

Abstract

Abstract A computerized motion control system for panning and tilting a television camera, motion picture camera or any other type of camera. The system includes a motorized camera head upon which a camera is mounted. The system also includes a digitizing tablet on which an observer follows the action transpiring before the camera with an electronic stylus by moving the stylus across the plane surface of the tablet. The resulting digital signals generated by the tablet and electronic stylus are fed to a computer in which they are converted to pan-and-tilt signals which are fed to the motorized camera head upon which the camera is mounted. The digital pan-and-tilt signals are converted to analog signals, and the analog signals activate pan-and-tilt camera head motors causing them to point the camera to a location determined by the operator by his placement of the electronic stylus on the digitizing tablet. In a second embodiment the digitizing tablet is replaced by a digital touch screen which is placed on a monitor and which carries the picture from the camera being controlled.
