PROBLEM TO BE SOLVED: To improve an object tracking performance as compared with before when an area for detecting the object is limited to reduce the load of detecting the object. SOLUTION: The track imaging device sets a position obtained by multiplying a position vector D of an "object 106 to be tracked" detected within the detection processing area 302 by a ratioα, as the next detection processing area 302. Then, even while reducing the load of detecting the object 106 to be tracked, the track imaging device exhibits satisfactory tracking performance. COPYRIGHT: (C)2010,JPO&INPIT
