PURPOSE: To enhance the display efficiency of the lost state of an object and the efficiency of position localization and motion analysis after researching, by converting an object existing region based on searching information directly before the lost of the object to a display mode different from that at the time of searching prior to displaying the same.
CONSTITUTION: An object searching sensor 1 sends out lost status information to an object motion analytical apparatus 3 when loses an object. The apparatus 3 converts the object existing region displayed by a display apparatus 6 to the display of the object exsiting region of which the display mode is changed from that at the time of searching and allows a memory apparatus 4 to store object lost information. By this method, an operator can easily recognize that the sensor 1 lost the object and an optimum working method for researching can be determined.
