说明过程的翻译

when fingers move on the surface of the sensor,the fingerprint information is picked and is transferred to the internal processor. Embedded fingerprint processing algorithm will process the image and extract the characteristic data and store the result into the fingerprint database.After this,the user becomes an authorised one.
Comparing of on-spot-picked fingerprint data with the database will be made when a user is to validized. If the result shows that the user is valid ,then the controlling circuit will output a controlling pulse or an instruction which denotes authorization.

When the finger evenly pulls in the sensor surface obsolete, gathers gradually to the entire fingerprint information, transmits to the internal processor in, the fingerprint algorithm which in inlays carries on the fingerprint image processing, withdraws the fingerprint characteristic data, and the memory in the fingerprint database, becomes has been authorized
