Biometric camera

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.
