<p>A living body recognizing device 10 is equipped with a captured image acquiring unit 11 which acquires captured images from infrared cameras 21, 22 having a characteristics that a luminance of an image portion of a target object becomes higher as a temperature of the target object becomes higher than a background, and the luminance of the image portion of the target object becomes lower as the temperature of the target object becomes lower than the background, according to a temperature difference between the background and the target object, a living body image extracting unit 12 which executes a first living body image extracting processing of extracting the image portion of the target object assumed to be a living body, from a region in the captured image in which the luminance is equal to or lower than a first threshold value Yth1, and a living body recognizing unit 14 which recognizes an existence of the living body, based on the image portion of the target object extracted by the living body image extracting unit 12.</p> |
