Abstract
A tracking system that provides high resolution images and a low tracking dropout rate is disclosed. The system uses a camera equipped with a dual-angle lens (or another dual-angle focusing system) to obtain both a wide-angle image and a narrow-angle image of a scene. The narrow-angle image provides a high resolution view of the scene. If the object being tracked moves out of the field of view of the narrow-angle image, the wide-angle image is used to find the object. The aim of the camera is then adjusted so that the object will once again appear in the narrow-angle image.
