ABSTRACT:
Electrical control system for a video tracker, including circuitry for maintaining the size of the target substantially constant relative to the tracking window, thereby improving the accuracy of the target shift detection circuit. Additional circuitry is provided for enhancing contrast between the target and the background scene, thus preventing loss of the target due to inadvertant sensing of grey clutter instead of the true target.
