Method and apparatus for authentication utilizing iris

摘要

A first image pickup unit mainly captures the image of whole face. A second image pickup unit mainly captures an image of iris in an eye. A display unit simultaneously displays both an image picked up by the first image pickup unit and an image picked up by the second image pickup unit on divided display regions, and naturally prompts a user to operate in such manner as to include himself/herself within an image pickup range. When the user moves his/her face or an authentication apparatus upon seeing this display, a relative position or direction of the iris and the image pickup device can be set to a desired state.
