POOR PHYSICAL CONDITION DETECTION DEVICE AND POOR PHYSICAL CONDITION DETECTION METHOD

摘要

A poor physical condition detection device (100) comprises: an image acquisition unit (101) for acquiring an image of the eyes of an occupant of a vehicle (1) during a predetermined first period after the eyes are irradiated with a flashing light; an exposure parameter acquisition unit (102) for acquiring an exposure parameter used when the image was captured; a pupil diameter detection unit (103) for detecting the pupil diameters of the eyes on the basis of the image; a reference pupil diameter determination unit (104) for determining a reference pupil diameter on the basis of the exposure parameter acquired by the exposure parameter acquisition unit (102); and a poor physical condition detection unit (105) for detecting a poor physical condition of the occupant on the basis of the pupil diameters detected by the pupil diameter detection unit (103) and the reference pupil diameter determined by the reference pupil diameter determination unit (104).
