Abstract
An imaging system for imaging a fingerprint operates in at least two different modes to provide both finger recognition and finger navigation applications. A light source illuminates a swipe interface having an elongated sensing area upon which a user swipes a finger. Light reflected from the finger is captured by an optical image sensor as image data representing a sequence of images resulting from motion of the digit over the sensing area of the swipe interface. The captured image data is output by the optical image sensor for processing of the data in one of the at least two different modes.
