PROBLEM TO BE SOLVED: To provide a human detector reduced in the rate of mistakenly detecting, as humans, objects such as headlights of an automobile, light sign boards, and tyres or an exhaust pipe of a parked vehicle, each having a temperature substnatially of the same order as an exposed part of a human body and occupying an area comparable therewith in a picture image. SOLUTION: This human detector is equipped with human candidate domain extracting means 330, 340 for extracting, as human candidate domains, domains having luminance higher than their peripheries in an infrared picture image taken of an area to be detected, and an area limiting means 350 for removing, from the area to be detected, domains that cannot be humans among the human candidate domains. |
