ABSTRACT:
A warm object detector that includes an infrared object detector and an ultrasonic object detector. A thermal image signal processor obtains thermal object information representative of a warm object in an area by processing signals from the infrared object detector. An ultrasonic processor obtains ultrasonic object information representative of an object in an area by processing signals generated by the ultrasonic object detector. Then a new object determining device determines the presence of a new object in the area by comparing ultrasonic object information supplied from the ultrasonic image signal processor at a prior time with ultrasonic object information being currently supplied by the ultrasonic image signal processor. The new object determining device provides output information representative of a determined new object. Then, a new warm object determining device determines the presence of a new warm object in the area by comparing the thermal object information obtained by the thermal image processor with the output information from the new object determining processor by overlapping the thermal object information with the output information.
