Acquisition module 10, in the touch operation in fingerprint recognition region mobile terminal is detected, obtaining described shifting The current dump energy of dynamic terminal；

Develop rapidly with scientific and technological, the mobile terminal such as smart mobile phone, PAD (panel computer) has become as in user's life Indispensable equipment, such as user can conveniently and efficiently carry out payment transaction, instant messaging etc. by smart mobile phone.For While user offers convenience, the safety of personal information and property also becomes the problem that user becomes more concerned with.Due to fingerprint Uniqueness, Fingerprint Lock is widely applied on mobile terminals.Generally user's fingerprint of oneself of typing in advance, afterwards with regard to basis The fingerprint of this typing in advance carries out fingerprint recognition, identifies and successfully just can unlock mobile terminal.Mobile eventually with unlocked by fingerprint below As a example end, method for controlling mobile terminal of the present invention is described in detail.

In the present embodiment, mobile terminal control device is arranged in mobile terminal, when user will refer to mobile terminal During line unblock, user executes the touch operation of input fingerprint in the fingerprint recognition region of mobile terminal, such as, if mobile terminal Home key is fingerprint recognition region, as shown in figure 4, when user presses the home key of mobile terminal, mobile terminal is detected The touch operation in fingerprint recognition region, now, acquisition module 10 obtains the current dump energy of mobile terminal.

Adjustment module 20, for when described dump energy is less than default power threshold, described mobile terminal is current Operational factor carries out reducing regulation, and described operational factor includes working voltage and running current；

In the present embodiment, it is previously provided with a default power threshold, such as, arranging this default power threshold is mobile terminal It is to be understood that this default power threshold flexibly can be arranged according to actual conditions, here does not limit the 30% of total electricity System.After acquisition module 10 gets the current dump energy of mobile terminal, if the current dump energy of mobile terminal is less than This default power threshold, illustrates that the electricity of now mobile terminal is inadequate, in order to extend the cruising time of mobile terminal, Now, reduce the power consumption of mobile terminal.Specifically, the current operating parameter of mobile terminal is carried out reducing and adjusts by adjustment module 20 Section, wherein, this operational factor includes the parameters such as working voltage and the running current of mobile terminal, namely it is current to reduce mobile terminal Working voltage and the parameter such as running current.

If the current dump energy of mobile terminal is more than or equal to this default power threshold, the electricity of now mobile terminal is described Amount is also more sufficient, and adjustment module 20 does not need to execute the operation of the current operating parameter reducing mobile terminal.

Processing module 30, for according to the current operating parameter after adjusting, gathering the corresponding user's of described touch operation Fingerprint to be measured, and described fingerprint to be measured is compared with the typing fingerprint prestoring, to determine whether fingerprint recognition successful.

In order to carry out fingerprint recognition, in the present embodiment, the fingerprint of user's typing oneself in the terminal in advance, mobile whole It is previously stored with the typing fingerprint of user's typing in end.When adjustment module 20 is adjusted to the current operating parameter of mobile terminal Afterwards, processing module 30 carries out fingerprint recognition according to the operational factor after adjusting.Specifically, processing module 30 gathers use first Family executes the corresponding fingerprint to be measured of finger of touch operation, and after collecting the fingerprint to be measured of user, processing module 30 will gather To this fingerprint to be measured compare with the typing fingerprint prestoring, judge whether this fingerprint to be measured is mated with typing fingerprint.Such as, Carry out the data message contrast of fingerprint, or carry out image information contrast of fingerprint etc..

Alternatively, when the current dump energy of mobile terminal is more than or equal to this default power threshold, processing module 30 Can directly according to mobile terminal under normal operating conditions when corresponding operational factor, collection user fingerprint, carry out fingerprint knowledge Not.

When the fingerprint to be measured of collection is with the typing fingerprint matching prestoring, illustrate to execute the use of the touch operation of input fingerprint Family is the user of typing fingerprint in advance, now, determines fingerprint recognition success.When determining fingerprint recognition success, you can execute solution Lock operation, when unblock completes, user just can be operated to mobile terminal accordingly.Otherwise, when the finger to be measured of collection When line and the typing fingerprint that prestores mismatch, then the user of the touch operation of explanation execution input fingerprint is not typing fingerprint in advance User, now, determine fingerprint recognition failure.

The scheme that the present embodiment proposes, in the touch operation in fingerprint recognition region mobile terminal is detected, obtains mould Block 10 first obtains the current dump energy of mobile terminal, if current dump energy is less than default power threshold, now, adjusts mould The current operating parameter (including working voltage, running current) of mobile terminal is carried out reducing regulation, then processing module by block 20 30 gather the fingerprint to be measured of user according to the current operating parameter after adjusting, and this fingerprint to be measured is entered with the typing fingerprint prestoring Row compares, to determine whether fingerprint recognition is successful.Current operating parameter due to mobile terminal reduces, and reduces mobile terminal and exists Carry out power consumption during fingerprint recognition, compared to the existing mode carrying out fingerprint recognition, improve the cruising time of mobile terminal.

Further, mobile terminal control device second embodiment of the present invention is proposed.Mobile terminal control device second is real The difference applying example with mobile terminal control device first embodiment is, in mobile terminal control device second embodiment, institute State adjustment module 20 to be used for：

In the present embodiment, be previously provided with mobile terminal under normal operating conditions when the corresponding operation of its operational factor Parameter value, and mobile terminal under low power operation state when the corresponding operational parameter value of its operational factor.For the ease of retouching State, below by mobile terminal under normal operating conditions when the corresponding operational parameter value of its operational factor referred to as first is default runs Parameter value, the corresponding operational parameter value of its operational factor referred to as second default fortune during by mobile terminal under low power operation state Line parameter value, wherein, this first default operational factor value is more than the second default operational factor value.

When the current dump energy of mobile terminal is less than default power threshold, adjustment module 20 first detects mobile terminal Current operating parameter is the first default operational factor value, or the second default operational factor value.If the current operation of mobile terminal Parameter is the first default operational factor value, namely the current operating parameter of mobile terminal is up corresponding operation during state Parameter value, now, the current operating parameter of mobile terminal is carried out reducing regulation by adjustment module 20, by the current fortune of mobile terminal Line parameter is adjusted to the second default operational factor value.Then processing module 30, according to the current operating parameter reducing after adjusting, is adopted The fingerprint to be measured of collection user, carries out fingerprint recognition.

If the current operating parameter of mobile terminal is the second default operational factor value, namely the current operation ginseng of mobile terminal Number has been corresponding operational parameter value during low power operation state, and now, adjustment module 20 avoids the need for again to mobile terminal Current operating parameter carry out reduction and have adjusted, processing module 30, directly under current low power operation state, gathers user Fingerprint to be measured, carry out fingerprint recognition.

Further, in the present embodiment, described adjustment module 20 is additionally operable to：

When the current dump energy of mobile terminal is more than or equal to default power threshold, adjustment module 20 first detects movement The current operating parameter of terminal is the first default operational factor value, or the second default operational factor value.If mobile terminal work as Front operational factor is the first default operational factor value, namely the current operating parameter of mobile terminal is up corresponding to during state Operational parameter value, now, adjustment module 20 continue to mobile terminal current operating parameter be the first default operational factor Value is constant, and processing module 30 directly gathers the fingerprint to be measured of user according to current operating parameter, carries out fingerprint recognition.

If the current operating parameter of mobile terminal is the second default operational factor value, namely the current operation ginseng of mobile terminal Number is corresponding operational parameter value during low power operation state, and now, adjustment module 20 is by the current operating parameter of mobile terminal Carry out increasing and adjust, the current operating parameter of mobile terminal is adjusted to the first default operational factor value.Then processing module 30 According to the current operating parameter increasing after adjusting, the fingerprint to be measured of collection user, carry out fingerprint recognition.

Further, as shown in figure 5, in the present embodiment, described mobile terminal control device also includes：

Determining module 40, for the corresponding relation according to default operational factor and fingerprint matching degree threshold value, determines and adjusts Current operating parameter corresponding fingerprint matching degree threshold value afterwards, and described fingerprint to be measured and the described typing fingerprint prestoring it Between fingerprint matching degree be more than adjust after current operating parameter corresponding fingerprint matching degree threshold value when, determine fingerprint recognition become Work(.

The fingerprint to be measured of the user being gathered under different operational factors due to mobile terminal is possible to can be different, mobile eventually When under low power operation state, the fingerprint matching degree between the fingerprint to be measured gathering and the typing fingerprint prestoring can be less than shifting at end Dynamic terminal under normal operating conditions when fingerprint matching degree between the fingerprint to be measured gathering and the typing fingerprint prestoring.Therefore, To mobile terminal under low power operation state when the fingerprint matching degree between the fingerprint to be measured gathering and the typing fingerprint prestoring When not needing to reach a very high matching degree, just determine fingerprint recognition success, otherwise be likely to occur being user originally I but the situation of recognition failures.In the present embodiment, it is previously provided with operational factor and finger during fingerprint matching of mobile terminal Corresponding relation between line matching degree threshold value, when the current operating parameter of mobile terminal is different value, accordingly fingerprint matching When fingerprint matching degree threshold value also different.When the current operating parameter of mobile terminal is less, corresponding fingerprint matching degree threshold value Also less.

After adjustment module 20 adjusts the current operating parameter of mobile terminal, determining module 40 runs ginseng according to default Number and the corresponding relation of fingerprint matching degree threshold value, determine the current operating parameter corresponding fingerprint matching degree threshold value after adjusting.If Fingerprint matching degree between fingerprint to be measured and typing fingerprint is more than the current operating parameter corresponding fingerprint matching degree threshold after adjusting Value, now, determining module 40 determines fingerprint recognition success, otherwise, if the fingerprint matching degree between fingerprint to be measured and typing fingerprint Less than the current operating parameter corresponding fingerprint matching degree threshold value after adjusting, now, determining module 40 determines fingerprint recognition failure.

For example, operational factor respectively the first default operational factor value and second pre-setting mobile terminal is previously run The operational factor of mobile terminal, for the ease of description, is preset by corresponding fingerprint matching degree threshold value below during parameter value for first During operational parameter value, corresponding fingerprint matching degree threshold value is referred to as the first fingerprint matching degree threshold value, and the operational factor of mobile terminal is During the second default operational factor value, corresponding fingerprint matching degree threshold value is referred to as the second fingerprint matching degree threshold value.
