Realization process, no longer describes herein.
Fig. 2 is referred to, Fig. 2 is a kind of flow diagram of unlocked by fingerprint method provided by the embodiments of the present application, is applied to
Above-mentioned mobile terminal, method include:
Step 201: it is detecting when unlocking event, TP sends the first interrupt requests to lower fingerprint sensor is shielded, and
The second interrupt requests are sent to processor, what the touch-control got rid of the region except the fingerprint collecting region is in put out screen state.
Wherein, being somebody's turn to do event to be unlocked is, for example, unlocking screen event etc., and being somebody's turn to do event to be unlocked is that mobile terminal is detecting
For fingerprint collecting region the second touch control operation when trigger, the second touch control operation can be clicking operation, be also possible to by
Press operation is also possible to slide, is not limited thereto.
In the implementation of the application, before detecting to unlock event, the method also includes: processor will
It lights to the first brightness in the fingerprint collecting region；
After receiving second interrupt requests, it is bright that the brightness in the fingerprint collecting region is adjusted to second by processor
Degree, second brightness are greater than first brightness.
Wherein, the first brightness can be the display brightness for the touch screen that mobile terminal is currently set, and be also possible to one in advance
If brightness, be not limited thereto.
Specifically, the second brightness is a preset brightness；Or second brightness be mobile terminal according to it is mobile eventually
The environmental light brightness of current environment is held to determine, such as according to the mapping relations of environmental light brightness and fingerprint collecting regional luminance
Determine corresponding second brightness of the environmental light brightness；Or second brightness be mobile terminal according to mobile terminal current geographic position
Set determining, the current geographic position as described in determining the mapping relations according to geographical location and fingerprint collecting regional luminance is corresponding
Second brightness；Etc..
As can be seen that in the embodiment of the present application, first fingerprint collecting region is lighted to a lower brightness, in fingerprint
When pickup area is by touch-control, then by the brightness raising of second area, improved relative to by the brightness in entire fingerprint collecting region, this
Application only improves the brightness of second area, reduces power consumption.In addition, just carrying out fingerprint after the brightness for improving second area and adopting
Collection operation, improves the quality of collected fingerprint image.
In the implementation of the application, before detecting to unlock event, the touch screen, which is in, puts out screen state,
The method also includes:
After receiving second interrupt requests, processor lights in the fingerprint collecting region to third brightness.
Wherein, third brightness is a brighter brightness, can be identical as the second above-mentioned brightness, can not also phase
Together, it is not limited thereto.
As can be seen that in the embodiment of the present application, when fingerprint collecting region is by touch-control, fingerprint collecting region is just lighted,
Blank screen unlock is realized, fingerprint collecting region is in addition only lighted, reduces power consumption.
Step 202: after receiving first interrupt requests, shields lower fingerprint sensor and carry out fingerprint collecting operation,
And collected first fingerprint image is sent to the processor and carries out fingerprint recognition operation, the fingerprint collecting operation is adopted
With the first strategy execution, second is used to increase the required duration of the fingerprint collecting operation and/or fingerprint recognition operation
Strategy execution, to increase the required duration of the fingerprint recognition operation.
Wherein, in the case that fingerprint sensor is fingerprint sensor under optical panel under screen, shields lower fingerprint sensor and carry out
The specific embodiment of fingerprint collecting operation has: shield lower fingerprint sensor acquisition optical signal, obtain an image, to the image into
Row image procossing, to obtain the first fingerprint image in the image.
Step 203: after receiving second interrupt requests, processor executes screen wake operation.

Step 205: in fingerprint recognition success, the processor is unlocked operation, and has operated in the unlock
Cheng Hou controls the touch screen and shows main interface.
Specifically, the process of unlocked by fingerprint is usually under current screen: for TP when detecting unlocking screen event, TP is to place
It manages device and sends interrupt requests；After processor receives the interrupt requests, processor executes screen wake operation, simultaneous processor
Interrupt requests are sent to lower fingerprint sensor is shielded；Shield lower fingerprint sensor after receiving the interrupt requests, carries out fingerprint and adopt
Collection operation, then issues processor for collected fingerprint image, and processor carries out fingerprint recognition operation.It is grasped since screen wakes up
Just shorter than duration required for fingerprint collecting+fingerprint recognition+unlocked by fingerprint, the prior art fingerprint of the script of duration required for making
The initial time of acquisition is also more early than the initial time that screen wakes up, so that unlocked by fingerprint completes the moment and screen wakes up and completes
Moment has enough regular hours poor, and splashette problem is not present.
And in this application, since TP is there are two pin, TP is being detected when unlocking event, and TP can refer to down to screen simultaneously
Line sensor and processor send interrupt requests, so that the initial time of fingerprint collecting is several with the initial time that screen wakes up
It is identical, so that unlocked by fingerprint completes the moment and screen wakes up the time difference shortening for completing the moment, there is splashette problem.
In that case, fingerprint collecting operation uses the first strategy execution, to increase needed for the fingerprint collecting operation
Duration and/or fingerprint recognition operation use the second strategy execution, with duration needed for increasing fingerprint recognition operation, into
And increase unlock and complete the time interval lighted with screen, avoid bring splashette problem due to promotion unlocks speed.Simultaneously
Because additionally added on TP one with shield under the interrupt pin that connect of fingerprint sensor so that detecting that finger touch fingerprint adopts
When collecting region, TP directly notifies that shielding lower fingerprint sensor carries out fingerprint collecting operation, improves unlock speed.
In the implementation of the application, first strategy includes: to increase after completing fingerprint image acquisition process
First delay implementation procedure；Or continuous acquisition multiple fingerprint images.
It should be noted that increasing by the first delay after the first strategy is included in completion fingerprint image acquisition process and executing
Journey, that is to say, that fingerprint collecting operation includes fingerprint image acquisition process and the first delay implementation procedure, and the first delay executes
Process is after fingerprint image acquisition process.
Further, duration needed for the first delay implementation procedure is determined based on the first formula, described first
Formula are as follows: T1=I- (T1-T2), the T1For duration needed for the first delay implementation procedure, the T1 is that this completes fingerprint image
As duration required for collection process, the T2 be it is estimated complete duration required for fingerprint image acquisition process, the I is the
One preset duration.Wherein, T2 is the value being previously set.
The first strategy execution is used in fingerprint collecting operation, and fingerprint recognition operation does not use the second strategy to hold
In the case where row, I=i- (T5-T6)；The first strategy execution is used in fingerprint collecting operation, and the fingerprint recognition operates
Also using in the case where the second strategy execution, I=(i- (T5-T6))/2, the i are splashette phenomenon occur visually observing not
Under, the shortest time interval at the completion moment for completing moment and unlock operation of screen wake operation, T5 is to be normally carried out screen
Duration required for wake operation, T6 are when being normally carried out fingerprint collecting to operate+be normally carried out required for fingerprint recognition operation
It is long.Wherein, T5 and T6 is the value being previously set.Such as, it is assumed that T5=255ms, T6=350ms, i=200ms, then I=
200ms- (350ms-255ms)=105ms.
As an example it is assumed that I=105ms, T1=150ms, T2=145ms, then T1=105ms- (150ms-145ms)
=100ms.Again as an example it is assumed that I=105ms, T1=145ms, T2=150ms, then T1=105ms- (145ms-
150ms)=110ms.
In the implementation of the application, second strategy includes: to increase by second after completing fingerprint identification process
Delay implementation procedure；Or increase by a fingerprint image treatment process in fingerprint recognition operation, the fingerprint image processing
Process is used to be promoted the quality of first fingerprint image.
It should be noted that increase by second after the second strategy is included in completion fingerprint identification process and delay implementation procedure,
That is fingerprint recognition operation includes fingerprint identification process and the second delay implementation procedure, the and postpone implementation procedure and referring to
After print image collection process.
Further, duration needed for the second delay implementation procedure is determined based on the second formula, described second
Formula are as follows: T2=J- (T3-T4), the T2For duration needed for the second delay implementation procedure, the T3 is that this completes fingerprint knowledge
Duration required for other process, the T4 is the estimated duration completing fingerprint identification process and needing, when the J is second default
It is long.Wherein, T42 is the value being previously set.
Wherein, J can be equal to I, can also be not equal to I, be not limited thereto.
As an example it is assumed that J=105ms, T3=200ms, T4=210ms, then T2=105ms- (200ms-210ms)
=115ms.Again as an example it is assumed that J=105ms, T3=210ms, T4=200ms, then T2=105ms- (210ms-
200ms)=95ms.
In the implementation of the application, duration needed for the delay implementation procedure be it is preset, set in advance
Fixed value is that testing staff is obtained based on detection data.
In the implementation of the application, the method also includes:
After fingerprint recognition failure, the processor controls the fingerprint collecting region display reminding information, the prompt
