METHOD AND DEVICE FOR CAPTURING FINGERPRINTS WITH RELIABLY HIGH QUALITY BASED ON FINGERPRINT SCANNERS

摘要

The invention is directed to a method and a device for capturing fingerprints (13) with reliably high quality based on fingerprint scanners (5). The object of the invention is to find a novel possibility for capturing fingerprints (13) of sufficiently high quality in which comprehensible feedback information of the capture process is given in real time so that the user can undertake any needed corrections of finger placement without active guidance. This object is met according to the invention in that an image processing unit (2) is arranged downstream of the capture unit (1) and a two-dimensional display unit (4) is associated with the capture unit (1). Depending on results of the fingerprints (13) analyzed in the image processing unit (2), the two-dimensional display unit (4) displays positive real-time depictions of the fingers placed on the capture surface (11) from an image storage (3) having a library comprising a plurality of animated finger position images for guiding the user in a simple manner.
