LIVING BODY DETERMINATION DEVICE, AUTHENTICATION DEVICE USING THE DEVICE, AND LIVING BODY DETERMINATION METHOD

摘要

A living body determination device for determining whether or not an object is an eye of a living body. The living body determination device has an imaging section for taking an image of an object, a light source section for emitting light rays to the object at an angle different from the angle at which the imaging section images the object, and a partial light spot detection section for detecting, from the image taken by the imaging section, a partial light spot of the object. The living body determination device determines whether or not the object is an eye of a living body depending on whether or not the partial light spot has been detected by the partial light spot detection section.
