Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, right
The present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, and
It is not used in the restriction present invention.
It should be noted that the executive agent of the embodiment of the present invention can be mobile terminal.Mobile terminal can include moving
Mobile phone (or be referred to as " honeycomb " phone, such as smart mobile phone) and there is the computer of mobile terminal, such as, panel computer, also may be used
To be mobile device portable, that pocket, Handheld vehicle borne computer are built-in, they with wireless access network exchange language and/
Or data.Such as, PCS (Personal Communication Service, PCS) phone, wireless phone, meeting
Words initiation protocol (Session Initiation Protocol, SIP) phone, WLL (Wireless Local
Loop, WLL) stand, the equipment such as personal digital assistant (Personal Digital Assistant, PDA), in this no limit.
Below in conjunction with specific embodiment, the realization of the present invention is described in detail:
Embodiment one
What Fig. 1 showed the method by unlocked by fingerprint mobile terminal that the embodiment of the present invention one provides realizes flow process, institute
State mobile terminal and include fingerprint chip, described fingerprint chip is built-in with micro controller unit (Micro Controller
Unit, MCU), details are as follows for described method:
In step S101, when mobile terminal is in holding state, if fingerprint chip detection is to described fingerprint chip quilt
External substance touches, then gather external substance image by described fingerprint chip.
In embodiments of the present invention, mobile terminal is concretely configured with the mobile phone of fingerprint chip, intelligent watch, flat board electricity
The equipment such as brain and notebook computer, preferably smart mobile phone.Described fingerprint chip is built-in with MCU.
Under normal circumstances, when mobile terminal is in holding state, in a dormant state, and fingerprint chip is in work to system
State, fingerprint chip can monitor whether oneself is touched by external substance in real time.If fingerprint chip detection is extraneous to fingerprint chip
Material touches, then gather external substance image by fingerprint chip.
Concrete, described external substance image is the image on the surface that external substance contacts with fingerprint chip.Such as, palm
When touching fingerprint chip, external substance image is the surface image of the partial skin that palm contacts with fingerprint chip.
In step s 102, judge whether described external substance image is fingerprint image by MCU built-in in fingerprint chip
Picture, if described external substance image is not fingerprint image, then performs step S103, otherwise performs step S104.
In embodiments of the present invention, can judge, by MCU built-in in fingerprint chip, the external world that fingerprint chip collects
Whether material image is fingerprint image.
Concrete, it is judged that whether external substance image is that the method for fingerprint image has and primary judges and senior judgement.Wherein,
In embodiments of the present invention, the method that primary judges is used.Concrete, the one of which in following four method can be used to enter
Row judges.The first, whether black and white contrast is obvious to judge external substance image by MCU；The second, judges the external world by MCU
Whether material image has obvious texture；By MCU, the third, judge that whether the coverage rate of external substance image is more than covering of presetting
Lid rate threshold values, the coverage rate threshold value wherein preset can be 50%).
The judgement of the above-mentioned image of material to external world is all to be performed by the small-sized MCU that fingerprint chip internal is built-in, it is not necessary to wake up up
The host CPU (Central Processing Unit, CPU) of mobile terminal system.If external substance image is discontented with
Any one in above-mentioned determination methods, then may determine that external substance image is not fingerprint image, then external substance image enough
It not that user's finger touch fingerprint chip causes, but misoperation, such as palm, or other contact skin of user's body
Fingerprint chip causes, at this moment, it is not necessary to starting host CPU, the power consumption of mobile terminal complete machine will not increase.
In step s 103, the host CPU CPU of described mobile terminal is not started.
In embodiments of the present invention, if judging to determine that external substance image is not fingerprint image, the most not by step S102
The host CPU starting mobile terminal processes, and the power consumption of mobile terminal will not increase.
In step S104, start the host CPU CPU of described mobile terminal, described host CPU perform fingerprint
Unlock flow process, complete the unblock of mobile terminal.
In embodiments of the present invention, if judging to determine that external substance image is fingerprint image by step S102, the most permissible
Start the host CPU CPU of mobile terminal at once, described host CPU perform the unblock flow process of fingerprint, complete mobile terminal
Unblock.
Preferably, host CPU can be controlled and work in highest frequency.Concrete, the coupling work of fingerprint is carried out at fingerprint chip
When making, can close other thread and run, make host CPU all for supporting fingerprint matching computing, the time is about 50ms.Pass through
This control, can save the fingerprint matching time, reduces the power consumption of mobile terminal.
Concrete, host CPU carry out unlocked by fingerprint time, first carry out the coupling of fingerprint, if the match is successful, then mobile terminal
Success unlocks, if it fails to match, then it represents that the fingerprint image collected is incorrect fingerprint image, it is impossible to match cognization,
Mobile terminal unlocks unsuccessfully.
By the embodiment of the present invention, can be when the external substance image that fingerprint chip collects not be fingerprint image, no
Start the host CPU of mobile terminal, thus reduce the power consumption of mobile terminal, overcome prior art external substance beyond finger
When touching on fingerprint chip, start the host CPU of mobile terminal because of mistaken touch, cause the problem that mobile terminal power consumption increases.
It addition, when the external substance image that fingerprint chip collects is fingerprint image, start the host CPU of mobile terminal,
And make described host CPU work in maximum operating frequency, improve the speed of fingerprint matching, reduce the power consumption of mobile terminal.
Should be understood that in embodiments of the present invention, the size of the sequence number of above-mentioned each process is not meant to the elder generation of execution sequence
After, the execution sequence of each process should determine with its function and internal logic, and should be to the implementation process structure of the embodiment of the present invention
Become any restriction.
One of ordinary skill in the art will appreciate that all or part of step realizing in the various embodiments described above method is can
Completing instructing relevant hardware by program, corresponding program can be stored in a computer read/write memory medium
In, described storage medium, such as ROM/RAM, disk or CD etc..
