PROBLEM TO BE SOLVED: To display a locus of a moving body on a photographed image that is available by photographing means whose photographing region is variable, on the photographed image.;SOLUTION: When a moving body 100 appears on a photographed image available using a PTZ camera as photographing means, operations of panning/tilting/zooming of the camera are so controlled as to automatically track the moving body 100. A current position mark 120 representing a current position of the moving body 100 is attached to the gravity center position of the moving body 100, obtained by the camera which is automatically tracking, on the photographed image. Every time the photographed image is updated by M frames, a locus mark 130 representing past positions which the current position mark 120 has travelled is attached, and, with the current position mark 120 as a top, a locus line 140 is so attached as to sequentially connect the locus marks 130 in time series. In short, the locus of the moving body 100 is displayed on the photographed image available with the camera which is automatically tracking.;COPYRIGHT: (C)2012,JPO&INPIT
