摘要： An apparatus used in a fingerprint identification for extracting minutia data from a fingerprint picture image data includes an optical sensor unit (11) for optically producing a sequence of fingerprint picture data during one pressing down operation of a fingerpad onto an inspection plate; and a data storing unit (2) for storing the produced fingerprint picture image data in the form of a sequence of fingerprint picture image data obtained during one pressing down operation of the fingerpad onto the inspection plate. The stored fingerprint picture image data is analysed by a minutiae data extracting circuit (32) to determine characteristics of the fingerprint and these are subsequently used for fingerprint identification.
