Claim One:
1. An apparatus comprising; a single illumination unit for illuminating objects; a processing unit configured to: obtain image data of a plurality of digital image frames captured by an image sensor of an assumed eye having an iris and a pupil, wherein a first digital image frame is captured by the image sensor while the assumed eye is illuminated from a first direction with the illumination unit and a second digital image frame is captured by the image sensor while the assumed eye is illuminated from a second direction with the illumination unit; generate an auxiliary image frame that combines a portion of the first digital image frame with a portion of the second digital image frame, wherein the auxiliary image frame defines at least one three-dimensional structural feature of the assumed eye; and detect the at least one three-dimensional structural feature of the assumed eye using image data in the auxiliary image frame from both the first digital image frame and the second digital image frame; and verify the iris using the at least one three-dimensional structural feature of the assumed eye detected from in the auxiliary image frame.
