Fingerprint image.Wherein, owing in fingerprint recognition module, some region is not pressed, therefore, it practice,
The number of the normal induction electrode comprised in fingerprint recognition module can be more than or equal to n2, and abnormal induction electrode
Number can be more than or equal to n1.
Still optionally further, the above-mentioned n2 collected according to n2 normal induction electrode of fingerprint recognition module
Individual normal bottom data value, determines n1 the bottom repair data value that n1 abnormal induction electrode is corresponding, can
For:
Pickup area is divided into multiple isolated area, and wherein, in multiple isolated areas, each isolated area all wraps
Containing multiple described normal bottom data values gathered by normal induction electrode with at least one by abnormal induction electrode
The abnormal bottom data value gathered, determines the average of all normal bottom data value in isolated area i, and will

During certain application is unlocked, fingerprint image can be mated with this preset fingerprint template, and
When fingerprint image is with preset fingerprint template matching success, the refresh page waiting to unlock application just can be shown.Can
Take the fingerprint the first fingerprint lines of image, at the second fingerprint stricture of vagina of the first fingerprint lines Yu preset fingerprint template
During the coupling of road, if matching value reaches certain threshold value, then it is believed that the first fingerprint lines and preset fingerprint template
The match is successful for second fingerprint lines, if matching value is not up to this certain threshold value, then it is believed that the first fingerprint lines
It fails to match with the second fingerprint lines of preset fingerprint template.Can be taken the fingerprint the characteristic point of image, such as
Harris angle point, Scale invariant features transform (Scale-invariant feature transform, SIFT) angle point,
So, can the fisrt feature point of fingerprint image of comparison collection and the second feature point of preset fingerprint template carry out
Coupling, if matching value reaches certain threshold value, then it is believed that the fisrt feature point of fingerprint image and preset fingerprint mould
The second feature Point matching success of plate, if matching value is not up to this certain threshold value, then it is believed that fingerprint image
Fisrt feature point is failed with the second feature Point matching of preset fingerprint template.
Alternatively, fingerprint image can be divided into multiple isolated area by terminal；In a parallel mode, by multiple
Each isolated area in isolated area mates with preset fingerprint template.I.e. there are how many isolated areas,
Just can use how many processes, each process is for mating an isolated area with preset fingerprint template.
104, when described fingerprint image is with described preset fingerprint template matching success, wait to unlock described in displaying and answer
With the described display page after being refreshed.
It can be seen that in the embodiment of the present invention, obtain fingerprint image when terminal is in bright screen state, obtaining

Can be by fingerprint image be analyzed, it is judged that whether fingerprint image comes from dry finger or wet finger.
Alternatively, terminal can judge fingerprint by the patterned feature of the image that takes the fingerprint by this patterned feature
Whether image comes from dry finger or wet finger.If the lines of fingerprint image is intermittent, then this fingerprint image
As belonging to dry finger, if fingerprint image occurs the fingerprint lines obfuscation of larger area, then this fingerprint image
As belonging to wet finger.
Alternatively, during terminal can determine that fingerprint image, definition is more than at least one region of the second predetermined threshold value；
Determine the average characteristics point number in this at least one region, it is judged that the average characteristics point in this at least one region
Number whether less than the 3rd predetermined threshold value, the most then confirms that fingerprint image is dry finger-image or wet finger figure
Picture.That is, by obtaining region more visible in fingerprint image, if the average characteristics point in this more visible region
Number be also less than a certain threshold value, then it is believed that the image that this fingerprint image is dry finger or wet finger
Image.
Alternatively, terminal can take the fingerprint the characteristic point of subregion of image；Judge the feature of fingerprint image
Whether the number of point is less than predetermined threshold value, if, it is determined that fingerprint image is the image of dry finger or wet hands
The image referred to.Wherein, subregion can be the appointment region in fingerprint image, such as, with fingerprint image
Center is the region of the default size of round dot.Subregion can be the random areas in fingerprint image.Wherein,
Predetermined threshold value can be fixed threshold, or, predetermined threshold value can be relevant to the area of fingerprint image.
Alternatively, can be by the number of the characteristic point of the image that takes the fingerprint, at the number judgement of characteristic point
In preset range.Wherein, this preset range may be less than first threshold, and such as, first threshold can be to preset
Certain percentage ratio of the feature point number of fingerprint image, such as, 50%, or, first threshold is system default
Certain value.Further, this preset range can be to be between Second Threshold and the 3rd threshold value, wherein,
Second Threshold is less than the 3rd threshold value, and the 3rd threshold value can be certain percentage of the feature point number of preset fingerprint image
Ratio, such as, 50%, or, the 3rd threshold value is certain value of system default, and Second Threshold can be preset fingerprint
Certain percentage ratio of the feature point number of image, such as, 30%, or, Second Threshold is certain of system default
Individual value.Under normal conditions, the feature point number of dry finger or wet finger is less, and terminal can take the fingerprint
The number of characteristic point, such as, if the number of this feature point is less than first threshold, then coming of this fingerprint is described
From in dry finger or wet finger.
204, if so, described fingerprint image is carried out image enhancement processing.
In implementing, because during the image of the image that fingerprint image is dry finger or wet finger, fingerprint image
The definition of picture is relatively low, thus, this fingerprint image can be carried out image enhancement processing.Image enhancement processing
Method may select histogram equalization, it is of course also possible to select other image enchancing method.Image enhaucament
After process, the contrast of fingerprint image can promote, and can extract more characteristic point or relatively sharp feature
Lines.
If it is not, the most directly perform step 205.
205, the described fingerprint image after described image enhancement processing is mated with preset fingerprint template.
206, the described fingerprint image after described image enhancement processing and the success of described preset fingerprint template matching
