ABSTRACT:
A heat source detector includes an infrared sensor 1 wherein plural infrared ray sensing elements 7 on which an infrared image is formed by an infrared lens 10 are arranged into an array form; and an infrared analyzer 2 which analyzes a detection signal detected by the infrared ray sensing elements 7. The infrared analyzer 2 has: an infrared intensity detecting unit 3 which detects the infrared intensity for each of the infrared ray sensing elements 7; an infrared center of gravity detecting unit 5 which obtains the center of gravity of a heat source emitting infrared rays, from the infrared intensities detected by the infrared intensity detecting unit 3, and a heat source moving direction detecting unit 6 which obtains the moving direction of the heat source, from temporal vector displacement of the center of gravity obtained by the infrared center of gravity detecting unit 5.
