Abstract
While both a forehead and a cheek are made in close contact to an eye position fixing portion, a space defined between an eye and a pinhole is shielded from extraneous light, and an iris is illuminated by infrared light of a lighting device. At this time, since a pupil diameter is defined in a self-control manner by receiving visible light of another lighting device, and also, a width of the iris is secured under stable condition, this iris is focused via the pinhole onto an image pick up element so that the iris can be photographed. Then, the acquired feature information of the iris is compared with registered feature information in order to execute the individual identifying operation.
