PROBLEM TO BE SOLVED: To stably detect and trace a mobile object to be tracked. SOLUTION: This system is constituted of a characteristic quantity extract means 3, that divides an image received from a CCD camera 2 into plural areas overlapped with each other to extract a characteristic quantity, a camera control means 11 that controls the movement of the CCD camera, a camera position detection means 6 that detects the position of the CCD camera 2, a background information memory 5 that stores background information of an image by an entire moving area of the CCD camera 2 depending on a detection position of the camera position detection means, a moving area detection means 7 that compares a characteristic quantity of the area extracted by the characteristic quantity extract means 3 updated for each frame with the background information and detects a moving area and selects a mobile object 1 to be tracked, and a cross detection means 10 that detects crossing of pluralities of mobile objects 1 detected by the moving area detection means 7, based on a color characteristic of the mobile objects 1.
