First Claim
1. A system for acquiring iris and face images, the system comprising:
- a sensor;
a lens, in optical communication with the sensor, to produce an out-of-focus infra-red image of an iris of a subject with the sensor and an in-focus non-infra-red image of a face of the subject with the sensor; and
a filter disposed between the sensor and the lens, the filter comprising a plurality of infra-red cut regions configured to pass visible light and to sample the in-focus non-infra-red image with the sensor, and a plurality of infra-red pass regions configured to pass infra-red light and to sample the out-of-focus infra-red image with the sensor, the plurality of infra-red pass regions configured to sample the out-of-focus infra-red image at or below a corresponding Nyquist limit for the infra-red pass regions.

Abstract
The present disclosure is directed towards a compact, mobile apparatus for iris image acquisition, adapted to address effects of ocular dominance in the subject and to guide positioning of the subject'"'"'s iris for the image acquisition. The apparatus may include a sensor for acquiring an iris image from a subject. A compact mirror may be oriented relative to a dominant eye of the subject, and sized to present an image of a single iris to the subject when the apparatus is positioned at a suitable distance for image acquisition. The mirror may assist the subject in positioning the iris for iris image acquisition. The mirror may be positioned between the sensor and the iris during iris image acquisition, and transmit a portion of light reflected off the iris to the sensor.

11. A method for acquiring iris and face images, the method comprising:
-
producing, using a lens and a sensor, an out-of-focus infra-red image of an iris of a subject and an in-focus non-infra-red image of a face of the subject; sampling, using a plurality of infra-red cut regions of a filter disposed between the sensor and the lens, the in-focus non-infra-red image, the plurality of infra-red cut regions configured to pass visible light; and sampling, using a plurality of infra-red pass regions of the filter, the out-of-focus infra-red image, the plurality of infra-red pass regions configured to pass infra-red light and to sample the out-of-focus infra-red image at or below a corresponding Nyquist limit for the infra-red pass regions. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
