PROBLEM TO BE SOLVED: To detect a position of a pupil with high accuracy.SOLUTION: A visible camera 23 photographs a visible image of a face of a detection object person. An infrared camera 22 photographs an infrared image of the face of the detection object person. An iris detection unit 31 detects an iris from the visible image photographed by the visible camera 23. A specification unit 32 specifies a search range of a pupil in the infrared image photographed by the infrared camera 22 on the basis of the position of the iris in the visible image detected by the iris detection unit 31. A pupil detection unit 33 detects a pupil in the search range specified by the specification unit 32. |
