Integrating optical fingerprinting into a front-facing smartphone camera

Abstract:

In some implementations, a control system may receive touch sensor signals from a touch sensor system indicating a camera area touch, the camera area touch corresponding to a target object touching a transparent cover in a camera area. The control system may control, responsive to the camera area touch, a light source system to provide light to the target object. The control system may receive, from the camera, image data corresponding to light reflected and/or scattered from the target object. The control system may perform a fingerprint authentication process based, at least in part, on the image data.
