Iris image pickup camera and iris authentication system

摘要

An imaging optical system 110 of an iris image pickup camera 100 has a common light axis in a region where an iris as an object is situated, and has first and second branch light axes branched from the common light axes. The imaging optical system 110 further has focusing ranges displaced from each other on the common axis for each of first and second branch light paths which passes through each of the first and second branch light axes. An imaging element 12 and an image processing section 13 generate image data of an iris image formed through the first and second branch light paths. Thus, an iris image pickup camera can be provided, which can promptly take an iris image for iris authentication in a simple configuration and without bothering a person to be authenticated.
