Information.
S204, the centre-of-pressure position for obtaining user's pressing and the fingerprint area coverage center.
In an embodiment of the present invention, centre-of-pressure position refers to that user's finger presses the face contact face of fingerprint collecting screen
Center, can be tried to achieve by face contact area, the distribution also dependent on pressing force angle value is asked for.Because user gathers fingerprint
Custom and finger end shape, determine that the centre-of-pressure position often correspond to the finger print region of user's finger.Determine in pressure
Heart position, it is possible to guarantee that user is in the finger print region pressing fingerprint collecting screen with finger.
Wherein, fingerprint area coverage center is the center of the effective area that fingerprint covers fingerprint induction zone.As in Fig. 3
The center of fingerprint area coverage 103 is the fingerprint area coverage center, in can asking which substantially by fingerprint area coverage 103
Heart position.It should be noted that the center of centre-of-pressure position and fingerprint area coverage center not only area, also
Including positional information of the central point on fingerprint collecting screen, specifically can be determined by the characteristic of fingerprint collecting screen, the collection screen class
The principle for obtaining the positional information that user clicks on of the capacitance plate of mobile phone is similar to, here is not described in detail.
S205, judge the centre-of-pressure position with the fingerprint area coverage center whether in predeterminable range scope
Interior.
In an embodiment of the present invention, predeterminable range scope is distance range, and the fingerprint according to most users collection is pressed
Pressure custom determines its maximum magnitude.Preferably, predeterminable range scope is the smaller the better, can improve the centre-of-pressure position and institute
Fingerprint area coverage center registration is stated, in order to reduce wrong report, it is also possible to suitably expand the predeterminable range scope, concrete root
Depending on according to actual effect.
If the S206 centre-of-pressure positions are with the fingerprint area coverage center in the predeterminable range scope
Interior, according to the default sensitivity that the pressure rating scope selects fingerprint sensor.
In an embodiment of the present invention, if the centre-of-pressure position is being preset with the fingerprint area coverage center
In distance range, it can be ensured that the centre-of-pressure position and the fingerprint area coverage center close proximity, so that
The finger print region for obtaining the fingerprint area coverage and user's finger of fingerprint induction zone overlaps, especially fingerprint compact district.So cause to adopt
The fingerprint of collection is readily identified.
Wherein, default sensitivity refers to the default sensitivity used during the fingerprint sensor collection fingerprint image, and this is preset
Sensitivity is corresponding with the pressure rating scope, the corresponding different default sensitivity of the different pressure rating scopes.
When the pressing force angle value of user determines its corresponding pressure rating scope, select the pressure rating scope corresponding default sensitive
Degree.Such as, in order to corresponding with the pressure rating scope, and different sensitivity is needed to be acquired fingerprint according to different pressures
Image, by the sensitivity of fingerprint sensor be divided into low default sensitivity, in preset sensitivity and high default sensitivity.For example use
The pressing force angle value at family determine its corresponding pressure rating scope be the light pressure rating scope when, now select the light pressure
The corresponding high default sensitivity of power rate range；The pressing force angle value of user determines that its corresponding pressure rating scope is described heavy
During pressure rating scope, the corresponding low default sensitivity of the weight power rate range is now selected.
S207, according to the default sensitivity calibration user finger print information.
In an embodiment of the present invention, referred to according to the finger print information of the default sensitivity calibration user：Fingerprint sensing
Device selects the corresponding default sensitivity of corresponding pressure rating scope to be acquired the fingerprint of user.Adopted according to different pressure
With different default sensitivity, the distortion factor of fingerprint image acquisition can be effectively reduced, improve the quality of image.Such as
During user's weight, fingerprint sensor is acquired to user fingerprints using low default sensitivity, due to user's finger weight fingerprint
Collection screen, user's finger and fingerprint collecting screen are fully contacted, if now fingerprint sensor can be caused using too high sensitivity
There is excessive noise in the image of collection, affects the extraction of the fingerprint characteristic of follow-up fingerprint image, if adopting low default spirit
Sensitivity is acquired, then can reduce noise very well, improves fingerprint image quality.
If the S208 centre-of-pressure positions are with the fingerprint area coverage center not in the predeterminable range scope
Interior, export the information for pointing out user to move pressing position.
Wherein, this step is, in the case that step S205 judged result is no, to execute the step.For pointing out user to change
Pressing position, again execution step S204 to S205 so that the centre-of-pressure position and the fingerprint area coverage centre bit
Put in the range of predeterminable range, it is ensured that finger print region of the fingerprint image of fingerprint induction zone collection for user's finger.
If the S209 fingerprint area coverages are not more than the preset area, the position of the fingerprint area coverage is obtained
Information；Determine that user's finger needs mobile azimuth information according to the positional information；Generated for pointing out according to azimuth information
The information of user's finger moving direction.
In an embodiment of the present invention, the positional information of fingerprint area coverage is specially fingerprint area coverage with respect to fingerprint sense
Answer the relative position information of district center.When the fingerprint area coverage is not more than the preset area, it may be possible to user's handss
Refer to and skew is occurred in that relative to fingerprint induction zone, can just cause the fingerprint area coverage to be not more than the preset area.
Wherein, azimuth information is that user's finger needs relative fingerprint to sense the moving direction of district center.Such as according to described
Positional information determines that user's finger is excessively to the left with respect to fingerprint sensing district center, causes the fingerprint area coverage to be not more than described
Preset area, it may be determined that user's finger needs relative fingerprint sensing district center to move right, and this moves right as family finger
Need mobile azimuth information.
Specifically, information includes information of voice prompt, text prompt information or animation information.The such as terminal
For mobile phone when, determine that user's finger needs mobile azimuth information for moving right according to the positional information, then can pass through
The display screen of mobile phone shows that arrow animation prompting user's finger moves right, preferably can also animation prompting plus voice message,
Information concrete form is not limited.
Above-described embodiment is judged by obtaining the pressing force angle value of user's finger and the fingerprint area coverage of fingerprint induction zone
It is pre-conditioned whether the pressing force angle value and fingerprint area coverage meet, if meeting condition, judges centre-of-pressure position and fingerprint
The registration of area coverage center, it is ensured that the fingerprint image of the collection of fingerprint induction zone is intensive for the fingerprint of user's finger
Area, further determines its corresponding described pressure rating scope and sensitivity according to pressing force angle value in addition, triggers fingerprint sensing
Device selects the finger print information of different default sensitivity calibration users.So as to ensure that the fingerprint image for collecting has enough contacts
Area, and compared using fixed sensitivity calibration with existing, fingerprint image quality is further increased, facilitates subsequent characteristics to carry
Take, and then improve the sensitivity of fingerprint recognition.
