Abstract: A computerized control system for automatically focusing televison cameras used for televising a sporting, or other event, as the cameras are panned to follow the action, and as the cameras are zoomed in on the action. The system includes a digitizing tablet on which an observer follows the action by moving a stylus continuously or from point-to-point across the plane surface of the tablet. The resulting digital signals generated by the tablet are fed to a computer in which they are converted to digital focusing signals which are fed to the televison cameras. The computer is programmed so that it generates a different set of focus control digital signals for each camera as determined by the actual location of the individual cameras around the playing area. The digital focusing signals are converted to analog signals at each camera, and the analog signals are used at the individual cameras to activate a servo motor which controls the focus of the camera.
