Abstract
In iris identification apparatus for performing personal identification by way of a shot iris image, a plurality of images are shot by using a camera whose quantity of a visible light included in an illuminating light irradiated onto a person to be shot differs from each other. The presence of a variation in the pupil diameter in the plurality of iris images is determined by a pupil size comparison processor. In case a variation in the pupil diameter is determined, personal identification by an iris identification processor based on any one of the plurality of iris images. Preferably, light emitting diodes for emitting a green light as a source of a visible light are used.
