Fig. 1 is the structural representation of a kind of fingerprint recognition system according to an exemplary embodiment, and as shown in Figure 1, this fingerprint recognition system can comprise:
Fingerprint recognition module 1;
Pressure detecting assembly 2, the sensing range of described pressure detecting assembly 2 at least covers central area 41 and the fringe region 42 of described fingerprint recognition module 1, to carry out pressure detection to described central area 41 and described fringe region 42 respectively;
Processing components 3, is connected to described fingerprint recognition module 1 and described pressure detecting assembly 2 respectively; Wherein, based on the pressure detection of pressure detecting assembly 2 and the processing capacity of processing components 3, can by the implementation method of the fingerprint recognition shown in Fig. 2, carry out control and management to fingerprint recognition module 1, the method can comprise the following steps:
In step 202., respectively pressure detection is carried out to the central area 41 of fingerprint recognition module 1 and fringe region 42, obtain pressure sensing result.
In the present embodiment, pressure detection is carried out by the central area 41 of pressure detecting assembly 2 pairs of fingerprint recognition module 1 correspondences and fringe region 42.
In step 204, when determine the fingerprint recognition of described pressure sensing result by user operate cause time, start described fingerprint recognition module 1.
In the present embodiment, the pressure sensing result obtained based on pressure detecting assembly 2 by processing components 3, carries out unlatching to fingerprint recognition module 1 and controls.
In the present embodiment, fingerprint recognition system can be applied in any electronic equipment.Wherein, processing components 3 can be the CPU in electronic equipment, this CPU except the fingerprint recognition module 1 for controlling in fingerprint recognition system, be also applied to other functions in electronic equipment and processing procedure; Or processing components 3 can be exclusively used in fingerprint recognition system, be different from the CPU in electronic equipment.
From above-described embodiment, the disclosure carries out pressure detection to the central area 41 of fingerprint recognition module 1 and fringe region 42, accurately can identify user and whether initiate fingerprint recognition operation; Wherein, only have when user initiates fingerprint recognition operation, determine that user exists the user demand to fingerprint recognition module 1, thus start fingerprint recognition module 1, to meet the fingerprint recognition demand of user.Visible, the disclosure can either meet the fingerprint recognition demand of user, and the time span that fingerprint recognition module 1 can be made again to be activated is short as far as possible, thus avoids the power consumption increasing electronic equipment, contributes to the standby time maintaining electronic equipment.
Fig. 3 is the process flow diagram of the implementation method of another kind of fingerprint recognition according to an exemplary embodiment, and as shown in Figure 3, the method is applied in fingerprint recognition system as shown in Figure 1, can comprise the following steps:
In step 302A, detect the force value F1 at central area 41 place of fingerprint recognition module 1.
In the present embodiment, as shown in Figure 4, central area 41 is positioned at the center of fingerprint recognition module 1, and finger, when performing fingerprint recognition operation, is often placed in this central area 41 place, to read the finger print data of user more accurately by user.
In step 302B, detect the force value F2 at fringe region 42 place of fingerprint recognition module 1.It is emphasized that: force value F1 and force value F2 should be detected simultaneously.
In the present embodiment, as shown in Figure 4, fringe region 42 can be positioned at the predeterminable area outside the edge of fingerprint recognition module 1; Certainly, as shown in Figure 5, fringe region 42 also can be positioned at the predeterminable area inside the edge of fingerprint recognition module 1.In fact, as long as can ensure that the distance between fringe region 42 and central area 41 is not less than predeterminable range, the user's area pressed formed when performing fingerprint recognition operation to make user and fringe region 42 have nothing to do.
In other words, as long as guarantee that user is when performing fingerprint recognition operation, only touches central area 41 as much as possible, avoids touching fringe region 42, thus make to form enough pressure difference values between force value F1 and force value F2; Certainly, this relates to the decision logic for fingerprint recognition operation in the disclosure, hereafter will describe accordingly.
Therefore, when fingerprint recognition module 1 is enough large or user points less (such as Asia user), as shown in Figure 5, can fringe region 42 be arranged at inside the edge of fingerprint recognition module 1; But, when fingerprint recognition module 1 is less or user's finger comparatively large (such as American-European user) time, as shown in Figure 4, can fringe region 42 be arranged at outside the edge of fingerprint recognition module 1, make it as much as possible away from central area 41, otherwise may occur the situation shown in Fig. 6, namely the finger of user forms pressing to central area 41 and fringe region 42, may there is the situation of erroneous judgement simultaneously.
Certainly, based on the reason such as inner structure of electronic equipment, if fringe region 42 is forced to inside the edge that needs to be arranged at fingerprint recognition module 1, then can arrange multiple fringe region 42, and using the average pressure value of multiple fringe region 42 as force value F2.Ratio as shown in Figure 6, two fringe regions 42 are arranged at the left and right sides of central area 41 respectively, even if so the fringe region 42 in left side is pressed against, but the fringe region 42 on right side is not pressed, thus can force value F2 be avoided to a certain extent excessive, contribute to the generation reducing erroneous judgement.
In step 304, judge whether force value F1 and force value F2 meets: force value F1 >=predetermined threshold value F, and force value F1-force value F2 >=preset difference value Δ F; If meet, then proceed to step 306, otherwise the current fingerprint recognition operation that there is not pressing or press also non-user execution is described, directly terminate.
In the present embodiment, two Rule of judgment are in fact comprised: the relative value size 1) between force value F1 and force value F2; 2) the absolute figure size of force value F1.Wherein:
For Rule of judgment 1) for; because the size of fingerprint recognition module 1 is limited, position is fixed; thus user is when performing fingerprint recognition operation; for self for the expectation of " successfully identifying " and the demand completing fingerprint recognition as early as possible; as far as possible exactly finger will inevitably be put into fingerprint recognition module 1; and meeting centering region 41 place usually, and can not arbitrarily place.
And when user to fingerprint recognition module 1 carry out false touch touch time, often such as whole palm, health etc. cause large area touching, can numerical value be caused close in central area 41 and fringe region 42 place force value.
Therefore, the feature that the fingerprint recognition based on user operates, the pressing position of finger must concentrate on central area 41 place, and can not be positioned at fringe region 42 place; Even if certain deviation may be there is, cause finger to touch fringe region 42, but also can be only that the edge pointed is touched, and the pressing strength of finger still concentrates on central area 41 place.
So, when user performs fingerprint recognition operation, between the force value F2 that force value F1 and fringe region 42 place of the formation of central area 41 place are formed, certainly exist certain pressure difference value, and by the quantification requirement to this pressure difference value, above-mentioned Rule of judgment 1 can be obtained).
For Rule of judgment 2) for, only have when user wishes to perform fingerprint recognition operation really, just can cause larger force value F1 to central area 41 place, thus when force value F1 is less, illustrate that user is very likely that false touch is touched, need to get rid of this situation.Therefore, Rule of judgment 2) false touch that may exist can be eliminated further touch problem.
Within step 306, determine that user performs to operate the fingerprint recognition of fingerprint recognition module 1.
In step 308, start fingerprint recognition module 1, perform the fingerprint recognition process to user.
In addition, in embodiment of the present disclosure, when fingerprint recognition system is installed in electronic equipment, may various structures be formed, be described respectively below:

Because pressure detecting assembly 2 needs to carry out pressure detection to the central area 41 of fingerprint recognition module 1 and fringe region 42 respectively, thus for convenience of description, pressure detecting assembly 2 can be divided into: Part I, for carrying out pressure detection to central area 41; Part II, carries out pressure detection for edge region 42.Certainly, those skilled in the art are it is to be understood that Part I herein and Part II belong to division in logic, pressure detecting assembly 2 might not be corresponded in division physically, in fact this Part I and Part II can be integral type structure, also can be separate type, the disclosure limit this.
As shown in Figure 7, time outside the edge that fringe region 42 is positioned at fingerprint recognition module 1, assuming that exist correspond to pressure detecting assembly 2 Part I region 1., corresponding to Part II region 2., then Part I can be placed in the 1. corresponding following any position in region: above panel construction 5, between panel construction 5 and fingerprint recognition module 1, or below fingerprint recognition module 1; And Part II can be placed in the 2. corresponding following any position in region: above panel construction 5, below panel construction 5, or below fingerprint recognition module 1 (now, although Part II is beyond fingerprint recognition module 1 coverage in the horizontal direction, but pressure transmission can be carried out by other structure (not shown)s between Part II and panel construction 5, and still can ensure that Part II is in vertical direction lower than fingerprint recognition module 1, thus thinks that Part II is in below fingerprint recognition module 1).
As shown in Figure 8, time inside the edge that fringe region 42 is positioned at fingerprint recognition module 1, assuming that exist correspond to pressure detecting assembly 2 Part I region 1., corresponding to Part II region 2., then Part I can be placed in the 1. corresponding following any position in region: above panel construction 5, between panel construction 5 and fingerprint recognition module 1, or below fingerprint recognition module 1; And Part II can be placed in the 2. corresponding following any position in region: above panel construction 5, between panel construction 5 and fingerprint recognition module 1, or below fingerprint recognition module 1.
Certainly, if the Part I of pressure detecting assembly 2 and Part II are integral type structure, then pressure detecting assembly 2 structure as a whole, following any position can be positioned at: above panel construction 5 in the embodiment shown in Fig. 7 or Fig. 8, between panel construction 5 and fingerprint recognition module 1, or below fingerprint recognition module 1.
2, capacitance type fingerprint identification module
When fingerprint recognition module 1 is capacitance type fingerprint identification module, as shown in figs. 9-10, the panel construction 5 of electronic equipment belonging to fingerprint recognition system offers the through hole 51 being matched with fingerprint recognition module 1, fingerprint recognition module 1 can be stretched out from the bottom of panel construction 5 by through hole 51.
As shown in Figure 9, time outside the edge that fringe region 42 is positioned at fingerprint recognition module 1, assuming that the region that there is the Part I corresponding to pressure detecting assembly 2 1., corresponding to Part II region 2., then Part I can be placed in the 1. corresponding following any position in region: below fingerprint recognition module 1 or top; And Part II can be placed in the 2. corresponding following any position in region: above panel construction 5, below panel construction 5, or below fingerprint recognition module 1 (now, although Part II is beyond fingerprint recognition module 1 coverage in the horizontal direction, but pressure transmission can be carried out by other structure (not shown)s between Part II and panel construction 5, and still can ensure that Part II is in vertical direction lower than fingerprint recognition module 1, thus thinks that Part II is in below fingerprint recognition module 1).
As shown in Figure 10, time inside the edge that fringe region 42 is positioned at fingerprint recognition module 1, assuming that the region that there is the Part I corresponding to pressure detecting assembly 2 1., corresponding to Part II region 2., then Part I can be placed in the 1. corresponding following any position in region: below fingerprint recognition module 1 or top; And Part II can be placed in the 2. corresponding following any position in region: below fingerprint recognition module 1 or top.
