An eye (EY) of a person to be shot is illuminated coaxially with the optical axis of a camera ( 11 ), and then, is shot. At this time, a retinal reflex is caused and the luminance in the pupil region becomes high if the eye (EY) is a living eye. A living eye judgment section ( 17 ) judges whether an eye included in the image is a living eye is performed based on the luminance in the pupil region of the image captured by the camera ( 11 ).
