Abstract
A tracking camera system which permits tracking an object with a plurality of cameras by changing the use of them from one camera over to another and is arranged to be capable of adequately capturing the object of tracking, without missing the object, even after one camera is changed over to another. The tracking object is decided within a display image plane. The attitude of camera in use for tracking is controlled in such a way as to have the tracking object always placed at the center of the display image plane. The tracking camera in use is changed over to another camera when the tracking object on display comes outside of the center part of the image plane, so that the object can be continuously tracked.
