Abstract: Digital visible light (RGB) cameras incorporating an NIR apodization filter having a gradual transmission for at least the NIR band. In some embodiments, the NIR apodization filter is incorporated into a camera module having a single aperture. The NIR apodization filter may effectively reduce the NIR aperture size relative to the RGB aperture size. In some embodiments, the different depth of field (DOF) associated with the different aperture sizes is employed to compute depth information for a scene (e.g., through a sharpness disparity function). In further embodiments, other image processing is based on the enhanced NIR information collected by a single-lens CM, or a multi-camera implementation where at least one CM of a multi-camera platform incorporates an NIR apodization filter.

Abstract: Infrared lamp control is described for use with iris recognition authentication. In one example, an eye of a face is detected using a user facing camera. A position of the detected eye with respect to an infrared (IR) camera is determined. The IR camera has a field of view and the detected eye does not fill the field of view of the IR camera. A time of exposure by the IR camera for the portion of the IR camera field of view filled by the detected eye is determined. The eye is then illuminated by activating an IR lamp during the time of exposure and deactivating the IR lamp after the time of exposure.
