Fingerprint recognition apparatus and data processing method |
摘要 |
The fingerprint recognition apparatus of this invention has a plurality of pixel units. Each pixel unit has a fingerprint sensor circuit including a sensor element for converting a three-dimensional pattern of a skin surface of a finger coming into contact with the element into an electrical signal, and a sensor circuit for processing the electrical signal converted by the sensor element and outputting predetermined data. Each pixel unit also has a fingerprint memory in which user's registered fingerprint data and a recognition circuit for collating the fingerprint data detected by the fingerprint sensor circuit with the registered fingerprint data. A control circuit controls the pixel units and totalizes recognition results.
