Embodiment
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, the every other implementation that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example, belongs to the scope of protection of the invention.
Fig. 1 shows the method for preventing fingerprint sensor false triggering according to the embodiment of the present application, can be by terminal device
Perform.As shown in figure 1, method includes：
Whether S110, the fingerprint sensor of detection setting on the terminal device receive the touch input of user's finger.
Alternatively, in certain embodiments, fingerprint sensor is optical fingerprint sensor, is sent out by detecting fingerprint sensor
The intensity of the light penetrated and the light received, judges whether fingerprint sensor receives the touch input of user's finger, for example,
If the intensity of the light received is weaker than the intensity of the light of transmitting, it is determined that fingerprint sensor receives touching for user's finger
Input is touched, otherwise it is assumed that fingerprint sensor is not received by the touch input of user's finger.
Alternatively, in further embodiments, fingerprint sensor is heat-sensitive type fingerprint sensor, can be by detecting fingerprint
Temperature at sensor surface judges whether fingerprint sensor receives the touch input of user's finger, if for example, detecting finger
The temperature of the different places of line sensor surface is different, then it is assumed that fingerprint sensor receives the touch input of user's finger, no
Then think that fingerprint sensor is not received by the touch input of user's finger.
S120, if detecting, the fingerprint sensor receives the touch input of user's finger, judges whether to meet to touch
Clockwork spring part.
Specifically, in certain embodiments, the trigger condition includes at least one of following condition：User's hand
Refer to effective slide area on the fingerprint sensor and be more than or equal to default effective slide area, the user's finger in institute
The glide direction stated on fingerprint sensor is more than or equal to default displacement, the end for default glide direction and displacement
The posture of end equipment is preset posture；
Alternatively, in S120, it is effective on the fingerprint sensor that the trigger condition includes the user's finger
Slide area, which is more than or equal to, presets effective slide area.Corresponding, judge whether to meet that trigger condition is specific in S120
Including：Before the touch input for detecting the user's finger terminates, the user's finger is gathered to preset acquisition interval
Multiple fingerprint images；Multiple described fingerprint images are synthesized to obtain target fingerprint image, not included in the target fingerprint image
The overlapping region of any two fingerprint images, the area of the target fingerprint image is defined as using in multiple described fingerprint images
Effective slide area of the family finger on fingerprint sensor；According to the area of target fingerprint image and effective slide area is preset,
Judge whether to meet trigger condition.
Thus, the method for preventing fingerprint sensor false triggering of the embodiment of the present invention, it is desirable to which user's finger is with certain area
Fingerprint Identification sensor (being slided on fingerprint sensor) is slowly contacted, and effective slide area on fingerprint sensor reaches
Certain threshold value can just trigger fingerprint sensor and carry out fingerprint matching, can effectively avoid the false triggering of fingerprint sensor.And
Multiple fingerprint pictures can be synthesized, be advantageous to improve fingerprint recognition success rate.
For example, as shown in Figure 2, it is assumed that fingerprint sensor is arranged on the side frame (side) of terminal device
On, the finger of user slides the position since Fig. 2 shown in leftmost figure along the direction of arrow on fingerprint sensor, when
When detecting that the finger of user touches fingerprint sensor, start to preset multiple fingerprint images that acquisition interval gathers finger,
After this multiple fingerprint image is removed into overlapping region, synthesis obtains a fingerprint image, the area essence of this fingerprint image
As effective slide area of the finger on fingerprint sensor, by the area of this fingerprint image with presetting effective slide area
Income compares, and is judged whether to meet trigger condition according to result of the comparison.
Alternatively, in certain embodiments, the specific number of multiple fingerprint images can be set, for example, can set most
More n fingerprint images of collection, n is the positive integer more than or equal to 2.In this case, even in collecting n fingerprint images
When, the touch input that the finger of user does not leave fingerprint sensor user's finger in other words yet does not stop yet, will also not continue to
Fingerprint image is gathered, but this n fingerprint images are subjected to synthesis processing.
Alternatively, in certain embodiments, it is described to detect before multiple fingerprint images are gathered with default acquisition interval
To the user's finger touch input terminate before, to preset multiple fingerprint images that acquisition interval gathers the user's finger
The step of also include：Determine that the contact area of user's finger and fingerprint sensor is connect the first preset exposure area and second are default
Between contacting surface product, wherein, the first preset exposure area is less than the second preset exposure area, and the second preset exposure area is less than or waited
In the effective area of fingerprint sensor.Thereby, it is possible to effectively reduce palm or larger object to cover fingerprint recognition and pass
Caused false touch problem on sensor.
Equally by taking Fig. 2 as an example, it is assumed that the effective area of fingerprint sensor is S, finger and fingerprint sensor contact area
A, only when A is more than or equal to A1 and is less than or equal to A2 (not shown in Fig. 2), just triggering starts to gather the fingerprint image of finger
Picture.Palm can effectively be reduced or larger object covers caused false touch problem on fingerprint Identification sensor.
Alternatively, in S120, the trigger condition includes the user's finger slip on the fingerprint sensor
Direction is default glide direction and displacement is more than or equal to default displacement.Corresponding, in S120, judge whether
Meet that trigger condition specifically includes：Obtain in the time interval of the touch input of user's finger from start to end, user's finger
Relative to the slip angle and displacement in the target direction of target direction；By the movement of user's finger in the target direction
Distance is defined as displacement of the user's finger on fingerprint sensor；Slide angle according to user's finger relative to target direction
Degree and displacement in the target direction, and default slip angle scope and default displacement, judge whether to meet to touch
Clockwork spring part.
It is understood that in the embodiment of the present invention, default glide direction can be a fixed direction or
One direction scope, this direction scope can be limited by two angles.
Specifically, in certain embodiments, if user's finger relative to the slip angle of target direction in default slide angle
In the range of degree, it is determined that glide direction of the user's finger on fingerprint sensor is default glide direction；If user's finger is referring to
Glide direction on line sensor is default glide direction, and the displacement on the target direction is more than or equal to default
Displacement, then judge to meet trigger condition.
For example, as shown in Figure 3, it is assumed that fingerprint sensor is arranged on the side frame (side) of terminal device
On, using horizontal direction as x-axis, coordinate system is established by y-axis of vertical direction.The b1 and b2 shown in leftmost figure in Fig. 3
Between angular range be default slip angle scope, start in the figure of the centre of the finger of user in figure 3 along arrow side
Slided to (P1 directions) on fingerprint sensor, along the direction of arrow (P2 directions) in fingerprint in the figure of rightmost in figure 3
Slided on sensor.
When detecting that fingerprint sensor receives the touch input of user's finger, obtain since touch input to knot
In the time interval of beam (or be interpreted as：Finger from touch fingerprint sensor to stop slide time interval in), user
Finger is relative to the slip angle of x-axis and the displacement in x-axis.As shown by the figure of the centre in Fig. 3, finger starts
When contacting fingerprint sensor, the slip angle relative to x-axis is a1.As shown by the figure of the rightmost in Fig. 3, finger stops
During slip, the slip angle relative to x-axis is a2.Finger from start contact fingerprint sensor to stop slide period in,
Displacement in x-axis is L.When judging whether to meet trigger condition, a1 and a2 specifically is judged whether between b1 and b2,
Whether L is more than or equal to default displacement Lm.If a1 and a2 are between b1 and b2, and L is more than or equal to Lm, then judges
Meet trigger condition.
Alternatively, in certain embodiments, the method shown in Fig. 1 also includes：Receive the setting instruction of user's input；According to
It is described that instruction is set, the target direction, the default slip angle scope and the default displacement are set.Thus, use
Family can combine the operating habit of user, the different trigger condition of personal customization, such as different target directions, different default
Slip angle scope and different default displacement etc., it is possible to reduce caused fingerprint recognition during other people using terminal equipment

In S120, judge whether to meet that trigger condition specifically includes：The current pose of terminal device is determined, according to current pose and is preset
Posture, judge whether to meet trigger condition.Thereby, it is possible to the feelings of fingerprint sensor false triggering caused by reducing hand-held terminal device
Condition.
Alternatively, in certain embodiments, user in the process of walking, during hand-held terminal device, easily causes fingerprint to pass
The false touch problem of sensor.Therefore, it is determined that before the current pose of terminal device, the method shown in Fig. 1 also includes：Determine terminal
The user of equipment is in walking states.That is, when the user of terminal device is in walking states, according to terminal device
Current pose and preset posture judge whether to meet trigger condition.Thereby, it is possible to reduce user's handheld terminal in the process of walking
The situation of the false triggering of fingerprint sensor caused by equipment.
Specifically, in certain embodiments, obtain the current pose of terminal device and can specifically obtain and be arranged on terminal and set
The data of gravity sensor in standby；According to the data of gravity sensor, the current pose of terminal device is determined.
Specifically, in further embodiments, the data for the acceleration transducer being arranged in terminal device are obtained；According to
The data of acceleration transducer, determine whether the user of terminal device is in walking states.
Alternatively, in certain embodiments, preset posture is the screen vertical of terminal device in ground.Herein, preset
Posture is that to can be understood as preset posture in ground be upright state to the screen vertical of terminal device.
S130, if judging to meet the trigger condition, trigger the fingerprint sensor and carry out fingerprint matching.
Alternatively, in certain embodiments, if carrying out fingerprint matching and the match is successful in S130, can perform with
The corresponding operation of user fingerprints, such as carry out unlocking screen operation or open the operation of some application.
