  • using a camera to capture a sequence of illuminated images of an subject, wherein the images are stored in frames;

    dynamically changing the focus point for each image captured so that the focus point sweeps from a far to a near end of a sweep range so that successive images have overlapping depths of field; and

    wherein the sweep range and overlapping depths of field provide that at least one image is focused on the iris of the eye of the subject.
