PURPOSE:To detect positional information as well as motion feature of a target in a wide-ranging searching by a method wherein positions and relative motion values of objects from an image controlling a sensor drive section in a wide- range searching mode and a narrow-range searching pattern is formed in the order of positions with a larger relative momentum so as to turn a visual line according to a narrow-range searching pattern. CONSTITUTION:A searching plan section 15 gives a command of the subsequent visual line drive angle to a sensor drive section 6 after receiving a detection data from a motion detecting section 13. Then, the plan section 15 sends a command to an infrared sensor 1 to switch an instantaneous field of view of a sensor over to a narrow field of view via the driving section 6. A data held of coordinates and a motion vector of a moving object collected in a wide-range searching mode are rearranged in the order of larger relative speed to be generated as a narrow-range searching pattern. Receiving a command of a through mode, a detection section 13 sends a infrared image as intact to a display section 4 as fed from an image processing section 2 and the end of the through mode is transmitted to the plan section 15 after a fixed time. |
