Description
Technical field
The present invention relates to acquisition technology field, and in particular to the fingerprint acquisition device for identity information acquisition.
Background technology
With the development of modern society, the collection and confirmation of identity information have become in people's daily life unavoidably
Important step.Fingerprint is unique, without two pieces of identical fingerprints.Although identical twin has height in line type
The similitude of degree, but its minutia is not fully identical, but certain difference be present.In addition, people's difference finger
Fingerprint is also different.Secondly, the fingerprint of people is unchangeable, and when children grow to manhood, fingerprint also only amplifies thickening,
The features such as its line shape, line number then keep constant.According to the characteristic of finger print information " different, constant throughout one's life ", the occurrences in human life in China
Registered permanent residence department is entered into finger print information as a kind of identity information in the related certificate such as identity document, is turned into this
A kind of key character of identity.
The fingerprint image acquisition of early stage is mainly with physics modes such as ink stamps, if ink and paper quality are asked
Topic, or press pressure are uneven, or pressing position, direction difference, or injury of finger, deformation etc., can all cause the fingerprint image of collection
Picture quality is undesirable, and then influences the technology application.It is smaller in view of fingerprint surface area, and abrasion be present, obtain high-quality fingerprint
Image is more difficult, especially shows and becomes apparent from fingerprint ridge image, so, gathered fingerprint image quality will certainly be caused to be difficult to
Ensure, cause the interpretation of automatic identification system of fingerprints difficult.The shortcomings that to overcome physics mode, the optical sensor of exploitation, partly lead
Body sensor, ultrasonic sensor etc. provide good technical guarantee to obtaining high quality fingerprint image, have practical very well
Value.It is optical fingerprint sensor to use at present most commonly used, and optical fingerprint image sensor undergoes long-term Practical Test, is
Stability of uniting is preferably, cost is also relatively low, can provide resolving power higher image.The fingerprint image of large area can particularly be realized
Collection, effectively overcomes the expensive shortcoming of large-scale semiconductor fingerprint sensor.But traditional optical fingerprint image sensor
Light source be either also the non-fingerprint collecting stage in the fingerprint collecting stage, the light source of optical fingerprint image sensor is constantly in
Open mode, required light source are high-power light-emitting equipment, and luminance is still within the non-fingerprint collecting stage, and consumption is unnecessary
Electric energy cause waste.
