A monitoring area is scanned by an area sensor device (e.g., an optical distance meter) to detect objects (step C2). Moving objects are identified among the detected objects (step C3), and, among the identified moving objects, a moving object which is present in the monitoring area and which has been newest identified is set as a tracking target (step C4). The moving object which has been set at the tracking target is automatically tracked by a camera device (step C5-C13). As a result, even if there are present a plurality of moving objects in the monitoring area, tracking targets can be switched from one to another, so that it is possible to designate, as a tracking target, a moving object desired by an observer. |
