Autotracking device designating a target

摘要

An automatic tracking device is disclosed that extracts data from the composite video output signal of a camera and uses it to electronically isolate an object in the image information on the video output signal and follows the object with a crosshair added to the video by the autotracking device. The autotracking device generates steering signals that are applied to the camera directing circuits to cause the camera to automatically follow the object as the object moves.
