This application provides techniques, including circuits and designs, which can receive information with respect to fingerprint images, or portions thereof, and which can be incorporated into devices using fingerprint recognition. This application also provides techniques, including devices which perform fingerprint recognition and methods which can be performed by those devices. In one embodiment, techniques can include providing a fingerprint recognition sensor in which one or more portions of each fingerprint can be collected as they are identified, and those portions can be combined into a unified fingerprint template. In this way, collection and enrollment of fingerprints may be simplified for users.
