<P>PROBLEM TO BE SOLVED: To solve problems of a conventional method wherein a supervising person needs to actually visit a place at which an object comes and confirm the object when the object moves outside the imaging range and the supervising person may lose the trace of the object because the moving direction of the object is hardly specified depending on a supervising place when the object moves outside the imaging range. <P>SOLUTION: When the object moves outside the imaging range, intruding object detection processing is stopped, the object moving direction is calculated on the basis of object moving information and a camera is directed in a direction in which the object exists. Thus, even when the object moves outside the imaging range, the moving direction of the intruding object is confirmed on a monitor. <P>COPYRIGHT: (C)2004,JPO |
