Abstract: A method of measuring a distance by using a 3-dimensional (3D) depth sensor is provided. The method may include: measuring m number of frames using light modulated at a first frequency to determine a first tentative distance from a viewpoint to an object at the first frequency, m being a positive integer; measuring n number of frames using light modulated at a second frequency to determine a second tentative distance from the viewpoint to the object at the second frequency, n being a positive integer, a sum of m and n being four; and determining a resulting distance to the object based on the first distance and the second distance.

Abstract: Exemplary embodiments for a biometric camera system for a mobile device, comprise: 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.
