Description
Technical field
The present invention relates to field of computer technology, in particular to the unlocked by fingerprint method under standby mode.
Background technique
With the progress of electronic technology, fingerprint recognition has been increasingly becoming using smart phone as the mark of the electronic equipment of representative
Match.Naturally, more stringent requirements are proposed for speed of the people to fingerprint recognition.
Under the prior art, when electronic equipment detects that user's touch fingerprint identifies mould group, collected finger can be identified first
Whether line is matched with preset fingerprint, only when collected fingerprint matching preset fingerprint, can just wake up system and unlock success.By
It is typically carried out in the standby state in current unlocked by fingerprint, therefore, identifies mould group to bright screen solution from user's touch fingerprint
Successfully entire unlocking process is locked, often allows user to feel that the waiting time is longer, experiences poor.
Summary of the invention
The purpose of the present invention is to provide a kind of unlocked by fingerprint methods under standby mode, so that electronic equipment collects finger
When print image, processing unit is first waken up to carry out fingerprint matching unlock by processing unit, to greatly improve the sound of unlocked by fingerprint
Answer speed, the system under fast wake-up system suspend mode.
In order to solve the above technical problems, embodiments of the present invention provide the unlocked by fingerprint side under a kind of standby mode
Method, applied to the electronic equipment comprising fingerprint recognition mould group and processing unit；Processing unit is transported always when being included in standby mode
Capable low-power consumption thread；The method includes the steps of: after fingerprint recognition mould group senses trigger signal, fingerprint recognition mould group is adopted
Collect piece image and piece image is sent to low-power consumption thread；Low-power consumption thread judges whether piece image is fingerprint
Image；If piece image is fingerprint image, low-power consumption thread generation system wake-up signal is so that processing unit enters just
Normal working condition；Fingerprint recognition mould group acquires at least piece image again, and the image acquired again is sent to processing unit；
Processing unit carries out unlocked by fingerprint according to from the received image of fingerprint recognition mould group；Wherein, received image includes at least again
The image of acquisition.
Embodiment of the present invention in terms of existing technologies, when low-power consumption thread judge fingerprint recognition mould group sensing simultaneously
When collected piece image is fingerprint image, system can be waken up immediately, processing unit is adopted again according to fingerprint recognition mould group
The image collected carries out unlocked by fingerprint, and when so that electronic equipment collecting fingerprint image, it is single by processing again first to wake up processing unit
Member carries out fingerprint matching unlock, so that the response speed of unlocked by fingerprint is greatly improved, the system under fast wake-up system suspend mode.
In addition, also including following step before low-power consumption thread judges the step of whether piece image is fingerprint image
It is rapid: if low-power consumption thread judges that preset fast wake-up mark is in the open state, to enter low-power consumption thread and judge first
The step of whether width image is fingerprint image；If low-power consumption thread judges that fast wake-up mark is in illegal state, fingerprint
Identification mould group acquires at least piece image again, and the image acquired again is sent to low-power consumption thread；Low-power consumption thread root
Unlocked by fingerprint is carried out according to from the received image of fingerprint recognition mould group.This step provides two kinds of fingers by increasing fast wake-up mark
Line unlocking manner meets the needs of different user for user's sets itself.
In addition, the step of low-power consumption thread is according to unlocked by fingerprint is carried out from the received image of fingerprint recognition mould group, comprising with
Lower sub-step: low-power consumption thread judges to match with the presence or absence of at least piece image with preset fingerprint image in received image；
If it exists, then low-power consumption thread generation system wake-up signal and unlock pass signal；Otherwise, low-power consumption thread generates unlock failure
Signal.Above-mentioned sub-step has refined the step of low-power consumption thread carries out unlocked by fingerprint, is conducive to embodiment of the present invention in reality
It is promoted in.
In addition, processing unit generate unlock failure signal the step of after, also comprise the steps of: processing unit according to
It unlocks failure signal and unlock failure prompting interface is provided.The step can remind user to unlock failure in time, and need again
Unlock, so that embodiment of the present invention is more humanized.
In addition, in low-power consumption thread generation system wake-up signal so that the step of processing unit enters working condition it
Afterwards, also comprise the steps of: that processing unit lights the display screen of electronic equipment.Processing unit is lighted immediately after entering working condition
The display screen of electronic equipment, so that whole process is more coherent, smooth, to improve the usage experience of user.
In addition, acquiring piece image simultaneously after fingerprint recognition mould group senses trigger signal, and in fingerprint recognition mould group
Before the step of piece image is sent to low-power consumption thread, it is flat also to comprise the steps of: that fingerprint recognition mould group carries out direct current
Weighing apparatus is adjusted.DC balance adjusting can make transimission power in electronic equipment keep stablizing, so that fingerprint recognition mould group be made to collect
It is more clear reliable image.
In addition, received image also includes piece image.Receiving image includes the image and the first width figure acquired again
Picture can make full use of all acquired images to be unlocked.
