Abstract: According to one example embodiment, a process and system include a camera used to capture a sequence of illuminated images of an subject, wherein the images are stored in frames. The focus point is changed for each image captured so that the focus point sweeps from a far to a near end of a sweep range, in discrete steps or continuous motion, so that successive images have slightly overlapping depths of field. The sweep range and overlapping depths of field provide that at least one image is well focused on the iris of the eye of the subject. In one other example embodiment, one or more of the images are illumined with a illumination fired for a respective captured image. In another embodiment, the sweep range is determined at least in part using a range finder or is otherwise controlled to determine a position of the subject so that the sweep range starts and stops a desired distance in front of and behind the subject, respectively.
