FINGERPRINT READING SYSTEM AND FINGERPRINT READING METHOD
Document Type and Number:
WIPO Patent Application WO/2015/096803
Kind Code:
A1
Abstract:
Disclosed are a fingerprint reading system and a fingerprint reading method. The fingerprint reading system contains a lens module, a control module and a signal processing module. The lens module is provided with a detection unit, an image acquisition unit, a liquid-state lens unit and a lighting unit. The control module is electrically connected to the lens module so as to control elements inside the lens module. When the detection unit detects a start signal, the control module starts the image acquisition unit, the liquid-state lens unit and the lighting unit; the liquid-state lens unit modulates a focusing distance from far to near to conduct fingerprint scanning; the image acquisition unit continuously acquires a plurality of fingerprint image photographs via the process of modulating the focusing distance from far to near by the liquid-state lens unit; and the signal processing module selects one photograph with correct focusing from the fingerprint image photographs acquired by the image acquisition unit and converts the photograph with correct focusing into a fingerprint picture.
