Abstract
The present invention is directed to an image tracking system that tracks the motion of an object. The image processing system tracks the motion of an object with an image recording device that records a first image of an object to be tracked and shortly thereafter records a second image of the object to be tracked. The system analyzes data from the first and the second images to provide a difference image of the object, defined by a bit map of pixels. The system processes the difference image to determine a threshold and calculates a centroid of the pixels in the difference image above the threshold. The system then determines the center of the difference image and determines a motion vector defined by the displacement from the center to the centroid and determines a pan tilt vector based on the motion vector and outputs the pan tilt vector to the image recording device to automatically track the object.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
