Abstract
A bodily state detection apparatus comprising a CCD camera, an infrared LED device, a pickup image memory, a pupil extraction circuit and a bodily state judgment circuit. The CCD camera inputs images of a predetermined area including the subject person's face. The infrared LED device illuminates the subject person in such a way that the optical axis of the camera and the direction of the illumination coincide with each other. The pickup image memory stores temporarily the output data of the CCD camera. The pupil extraction circuit extracts the subject person's pupil position from the pickup images. The bodily state judgment circuit judges the subject person's bodily state by use of the result of pupil extraction performed by the pupil extraction circuit.
