Abstract
A photography subsystem is configured to be operated in fingerprint scanning mode and a normal mode. An autofocus module may be initialized to control a lens with an initial focal length set according to received instructions indicating one of the modes of operation. An image signal processor associated with the photography subsystem may process images received from the photography subsystem and, if necessary, process the images to form a candidate digital fingerprint for use in an authentication process.
