Claim One:
1. An iris recognition apparatus for recognizing an iris in an eyeball, the apparatus comprising: a first image collection unit collecting a narrow angle of view image of the eyeball; a second image collection unit comprising a lens having a larger angle of view than a lens of the first image collection unit and collecting a wide angle of view image of the eyeball; and a control unit: correcting the narrow angle of view image based on a ratio between the angle of view of the lens of the first image collection unit and the angle of view of the lens of the second image collection unit, measuring the distance between the eyeball and the iris recognition apparatus based on a first measure of a proportional distance of the eyeball of the narrow angle of view image corrected and a second measure of a proportional distance of the eyeball of the wide angle of view image, and performing iris recognition using the narrow angle of view image not corrected if the eyeball is located within an iris recognition operating range.
