1. A living eye judging method comprising:
- a first step of obtaining an image captured by shooting a subject with illumination coaxial with an optical axis of a camera; and
a second step of judging whether an eye included in the image is a living eye or not based on luminance in a pupil region of the eye in the image.

Abstract
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).

8. An living eye judging method comprising:
-
a first step of obtaining a first image captured by shooting a subject with illumination coaxial with an optical axis of a camera and a second image captured by shooting the subject with illumination having an optical axis different from the optical axis of the camera; and
a second step of judging whether an eye included in the first and second images is a living eye or not based on luminance in pupil regions of the eye in the first and second images. - View Dependent Claims (9, 10)

11. A living eye judging device comprising:
-
a camera for shooting a subject;
an illumination section for illuminating the subject coaxially with an optical axis of the camera; and
a living eye judgment section that receives an image captured by the camera with illumination by the illumination section and performs judgment as to whether an eye included in the image is a living eye or not based on luminance in a pupil region of the eye in the image.

12. A living eye judging device comprising:
-
a camera for shooting a subject;
a first illumination section for illuminating the subject coaxially with an optical axis of the camera;
a second illumination section for illuminating the subject on an optical axis different from the optical axis of the camera; and
a living eye judgment section that receives a first image captured by the camera with illumination by the first illumination section and a second image captured by the camera with illumination by the second illumination section and performs judgment as to whether an eye included in the first and second images is a living eye or not based on luminance in pupil regions of the eye in the first and second images.
