Under type is implemented：
The fingerprint image is matched with N number of fingerprint template using N number of thread or process, wherein, it is each
Thread or process are corresponded with N number of fingerprint template.
Alternatively, if the fingerprint image in step 101 is the fingerprint image under designated state, above-mentioned designated state can be
Wet finger state or dry finger state.Specifically, can determine whether fingerprint image whether be wet finger or dry finger image, if
Fingerprint image comes from the fingerprint image of wet finger or dry finger, then, terminal can be carried out at image enhaucament to fingerprint image
Reason, and judge whether the similarity between the fingerprint image after image enhancement processing and preset fingerprint template is pre- more than above-mentioned second
If threshold value.If fingerprint image is not being from the fingerprint image of wet finger or dry finger, then, can directly perform step 103.
Wherein, the method for image enhancement processing may include：Histogram equalization is carried out to fingerprint image, gray scale stretching, image restoration is small
Wave conversion etc..
Alternatively, in implementing, due to the fingerprint lines in the fingerprint image of dry finger intermittently, and wet finger
The fingerprint image larger area fingerprint lines obfuscation of fingerprint image, is almost hard to tell fingerprint lines, thus, can be by fingerprint
Image is analyzed, and judges whether fingerprint image comes from dry finger or wet finger.For example, can be by the image that takes the fingerprint
Patterned feature, to judge whether fingerprint image comes from dry finger or wet finger.If the lines of fingerprint image is intermittently,
Then the fingerprint image belongs to dry finger, if occur the fingerprint lines obfuscation of larger area in fingerprint image, the fingerprint image
As belonging to wet finger.

Wherein, during user touches fingerprint recognition module, due to touching degree (touching intensity, touch angle) no
Equally, thus, the fingerprint area of the fingerprint image for obtaining is different, thus, it may be determined that the finger of the fingerprint area and fingerprint template
(if there is N number of fingerprint template, the fingerprint area of above-mentioned fingerprint template is the average of N number of fingerprint template to ratio between line area
Area), in this way, first object matching threshold can be determined according to the ratio.For example, the second target fingerprint recognition threshold can be using such as
Lower formula is obtained：
B=a* (B/A)；
Wherein, A is the fingerprint area of fingerprint template, and B is the fingerprint area of fingerprint image, and a is the second predetermined threshold value, and b is
Second target fingerprint recognition threshold, wherein, B<A, when B is more than or equal to A, b=a.
103rd, the M fingerprint template in the fingerprint image with N number of fingerprint template be when the match is successful, in the finger
Line list interface highlights the finger print information of the M fingerprint template, and the M is less than or equal to the positive integer of the N.
Alternatively, the M fingerprint template in fingerprint image with N number of fingerprint template, can be in fingerprint list when the match is successful
Interface highlights the finger print information of the M fingerprint template simultaneously, for example, the corresponding finger print information of M fingerprint template carries out word and adds
Slightly, and for example, list display pre-set color where the finger print information display of M fingerprint template, for example, red, blueness etc..

32) fingerprint of the M fingerprint template, is highlighted according to the M matching value successively at the fingerprint list interface
Information.
Wherein, after fingerprint image and any fingerprint template matches, can obtain a matching value, above-mentioned fingerprint image with it is upper
After stating M fingerprint template the match is successful, M matching value is obtained, certainly, the matching value varies, thus, can be according to the M
The size of matching value is that above-mentioned M fingerprint template sets a priority, for example, matching value is bigger, priority is higher, and or
Person, matching value is smaller, and priority is higher, so that, the priority orders of the M fingerprint template are obtained, according to the priority orders
The finger print information of the M fingerprint template can be successively highlighted at fingerprint list interface.For example, priority orders are：Fingerprint 1, refer to
Line 3 and fingerprint 6, then can first highlight fingerprint 1, after highlighting, keep the state of current finger print 1, then, highlight fingerprint 3, keep working as
The state of preceding fingerprint 3, finally, highlights fingerprint 6, the state of current finger print 6 is kept, in this way, user may know that fingerprint 1, the and of fingerprint 3
Fingerprint 6 comes from the fingerprint of same finger, thus, the fingerprint 1, fingerprint 3 and fingerprint 6 further can be added to same finger
Line group, the title of the fingerprint group can be the position (for example, right hand middle finger) of finger, so, it is convenient to which fingerprint template is carried out
Editor's (for example, fingerprint title of modification fingerprint template) and management are (for example, the fingerprint template that will belong to same finger is added to one
Individual fingerprint group).
Alternatively, involved highlighting may include but lose to be limited in the embodiment of the present invention：Highlight color, highlight font
Size, highlight flashing times (frequency) etc..
Alternatively, in above-mentioned steps 103, the finger print information of the M fingerprint template is highlighted at the fingerprint list interface,
May include following steps：
Show the finger print information of the M fingerprint template in fingerprint list interface, and hide in N number of fingerprint template except
The finger print information of other fingerprint templates of the M fingerprint template.
Alternatively, after step 102, following situation can also be included:
When any fingerprint template is mismatched in fingerprint image with N number of fingerprint template, whether the fingerprint image is can determine whether
Fingerprint from finger, can be using grader (such as neural network classifier, SVMs (Support Vector
Machine, SVM) grader etc.) machine learning can be carried out to the fingerprint image, so that, it may be determined that whether the fingerprint image comes from
In the fingerprint of finger, when the fingerprint image comes from the fingerprint of finger, then user's non-typing fingerprint of the finger is pointed out, referred at this
When print image is come the fingerprint for being not from finger, then the prompting user finger cannot typing fingerprint.
As can be seen that by the embodiment of the present invention, when mobile terminal is in fingerprint list interface, fingerprint image is obtained,
Comprising the finger print information of the N number of fingerprint template for prestoring in fingerprint list interface, N is positive integer, by fingerprint image and N number of finger
Line template is matched, and the M fingerprint template in fingerprint image with N number of fingerprint template be when the match is successful, in fingerprint list circle
Face highlights the M finger print information of fingerprint template, and M is the positive integer less than or equal to N.In this way, above-mentioned M fingerprint template can be learnt
Which finger come from, by that analogy, user can determine that the source of each fingerprint template in N number of fingerprint template.And then, can be conveniently
