Abstract
A method and system for fingerprint imaging in an electronic device having a display, a touch sensor with a touch interface and an optical fingerprint sensor with a sensing region is described. The method and system include placing the electronic device in a hover detect mode, the hover detect mode scanning for a hovering finger; detecting the hovering finger; initiating illumination in the sensing region to image a fingerprint of the finger; capturing an image of the fingerprint in the sensing region; and disabling the illumination in the sensing region.
