Abstract
A method of processing video images includes capturing a first image with a camera having a first field of view. The capturing occurs at a first point in time. Commands are transmitted to the camera to make pan, tilt and zoom movements. A second image is captured with the camera at a second point in time. The second point in time is after the movements have commenced. A second field of view of the camera is calculated at the second point in time. The calculating is based upon the commands. The second image is processed based upon the first field of view and the calculated second field of view.
