BIOMETRIC CAMERA
First Claim
1. A biometric camera system for a mobile device, comprising:
- a near infrared (NIR) light source on the mobile device that flashes a user of the mobile device with near infrared light during image capture;
a biometric camera located on the mobile device offset from the NIR light source, the biometric camera comprising;
an extended depth of field (EDOF) imaging lens;
a bandpass filter located adjacent to the EDOF imaging lens to reject ambient light during image capture; and
an imaging sensor located adjacent the bandpass filter that converts an optical image of an object into an electronic signal for image processing; and
a processor configured to receive video images of an iris of a user from the image sensor, and attempt to match the video images of the iris with previously registered images stored in an iris database, wherein if a match is found, the user is authenticated.

13. A biometric camera system for a mobile device, comprising:
-
a front-facing camera; a near infrared (NIR) light source on the mobile device that flashes a user of the mobile device with near infrared light during image capture, the NIR light source being covered with a structured light pattern; a biometric camera located on the mobile device offset from the NIR light source, the biometric camera comprising; an extended depth of field (EDOF) imaging lens; a bandpass filter located adjacent to the EDOF imaging lens to reject ambient light during image capture; and an imaging sensor located adjacent the bandpass filter that converts an optical image of an object into an electronic signal for image processing; and a processor configured to; use the front-facing camera to capture RGB images of a user'"'"'s face; use the NIR light source with the structure light pattern and the biometric camera to capture one or more 3D depth maps of the user'"'"'s face; use the RGB images and the one or more 3D depth maps to create a 3D model of the user'"'"'s face; and use the 3D model to create a biometric signature for the user. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
