Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other implementation acquired under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Finger print information processing method provided in an embodiment of the present invention is illustrated first below.
It should be noted that finger print information processing method provided in an embodiment of the present invention is applied to mobile terminal.Specifically,
The mobile terminal can be any equipment for having communication function, such as：Mobile phone, tablet personal computer (Tablet Personal
Computer), laptop computer (Laptop Computer), personal digital assistant (personal digital

Referring to Fig. 1, the flow chart of finger print information processing method provided in an embodiment of the present invention is shown in figure.Such as Fig. 1 institutes
Show, this method is applied to mobile terminal, and the touch screen of mobile terminal is arranged with fingerprint sensor, and this method includes following step
Suddenly：
Step 101, when touch control operation of the detection to touch screen, the positional information of touch control operation is obtained.
Wherein, mobile terminal can timing or sporadically determine whether to detect touch control operation.If mobile terminal
Clicking operation, pressing operation or other kinds of touch control operation are detected, mobile terminal obtains the positional information of touch control operation.
Specifically, the positional information of touch control operation can be characterized by coordinate.
Step 102, according to positional information, fingerprint detection region is determined.
In a kind of embodiment of the embodiment of the present invention, positional information includes the centre bit in the region of touch control operation
Put the coordinate in coordinate system corresponding to touch screen；
According to positional information, fingerprint detection region is determined, including：
According to the coordinate and pre-determined distance of center, fingerprint detection region is determined.
It should be noted that according to the coordinate and pre-determined distance of center, the specific implementation in fingerprint detection region is determined
It is various informative, citing introduction is carried out to two kinds of ways of realization therein below.
In the first way of realization, as shown in Fig. 2 coordinate system corresponding to touch screen is using the lower left corner of touch screen as original
The coordinate system of point；The coordinate of center includes abscissa X1 and ordinate Y1；
At this moment, according to the coordinate and pre-determined distance of center, fingerprint detection region is determined, can be included：
Respectively calculate center abscissa X1 and default first distance M difference X2, X1 and M and value X3, in
The ordinate Y1 of heart position and default second distance N difference Y2, and Y1 and N's and value Y3.
Alternatively, default first distance M is more than or equal to 8 millimeters and less than or equal to 10 millimeter.Specifically, M takes
Value can be other numerical value between 8 millimeters, 9 millimeters, 10 millimeters or 8 millimeters to 10 millimeters.
Alternatively, default second distance N is more than or equal to 8 millimeters and less than or equal to 10 millimeter.Specifically, N takes
Value can be other numerical value between 8 millimeters, 9 millimeters, 10 millimeters or 8 millimeters to 10 millimeters.It is pointed out that M and N
Value can be with identical, can also be different.
It is defined as referring to by the region formed is surrounded by tetra- straight lines of X=X2, X=X3, Y=Y2 and Y=Y3 in coordinate system
Line detection zone.
Assuming that the region for the touch control operation that mobile terminal detects is to surround the area formed by the ellipse in Fig. 2 or Fig. 6
Domain, by the reasonable setting of the value to M and N it can be seen from Fig. 2 and Fig. 6, by X=X2, X=X3, Y=Y2 and Y=Y3
Four straight lines, which surround the fingerprint detection region to be formed, can include the region of touch control operation completely, also, compared to touch screen
For full frame area, the area in fingerprint detection region is much smaller.
As can be seen that in the first way of realization, mobile terminal very convenient can quickly determine fingerprint detection
Region.
In second of way of realization, according to the coordinate and pre-determined distance of center, fingerprint detection region is determined, can be with
Including：
By, using the coordinate of center as the center of circle, pre-determined distance is defined as referring to for the region that the circle of radius surrounds in coordinate system
Line detection zone.
Wherein, pre-determined distance can be 9 millimeters or 10 millimeters, and certainly, the value of pre-determined distance is not limited thereto, tool
Body can determine that the present embodiment does not do any restriction to this according to actual conditions.
Assuming that the region for the touch control operation that mobile terminal detects still is to be surrounded to be formed by the ellipse in Fig. 2 or Fig. 6
Region, then, by the reasonable setting to pre-determined distance, by using the coordinate of center as the center of circle, pre-determined distance is radius
Circle surround the fingerprint detection region formed and can also include the region of touch control operation completely, it is also, complete compared to touch screen
For panel product, the area in fingerprint detection region is also much smaller.
As can be seen that in second of way of realization, mobile terminal also very convenient can quickly determine that fingerprint is examined
Survey region.
