Research and Application of Pressure Sensitive Fingerprint Acquisition System

摘要

This paper designs a complete fingerprint acquisition system which uses new-style of pressure sensitive fingerprint sensor chip BLP100 and fingerprint control chip BCT100. The system has characteristics of simple structure, fast capturing speed, high quality image, connecting with external processor easily and so on. Compared with the original images, the images that acquired by this system have been normalized and filtered, and the result shows that this system can obtain the fingerprint image information more easily and reliably.
