Integration of TV video with IR tracker features
First Claim
1. A system for tracking a target, said system comprising:
- first means for providing standard television format video input signals;
a signal processor for processing said video input signals to provide intermediate analog and digital signals;
a control tracker for processing said intermediate analog signals to provide centroid tracking of said target; and
a correlation tracker for processing said intermediate digital signals to provide correlation tracking of said target.

Abstract
A tracking system (200) adapted to receive input imagery and provide standard television format video input signals in response thereto. The video input signals are processed (228) to provide intermediate analog and digital signals. The intermediate analog signals are further processed (239) to provide centroid tracking of a target. The intermediate digital signals are processed (236) to provide correlation tracking of the target. In a specific implementation, the standard television format video input signals are provided by a charge coupled device (214), a Vidicon camera, an infrared focal plane array, a Newvicon camera or other device which generates standard television format video signals. A video rotation circuit may be used to provide proper image orientation regardless of the mounting orientation of the system. The invention provides a tracking system which allows for the direct use of video signals from a camera or other signal by a digital processing system without the requirement for scan conversion.
