Below based on the framework shown in Fig. 1, following each embodiment is proposed.
Embodiment one
Embodiments provide the control method of a kind of terminal, as in figure 2 it is shown, the method may include that
S101, when trigger solve latching operation time, enter keystroke pattern, detect whether to activate the first preset function.
Respond it should be noted that embodiments provide one based on control terminal on fingerprint identification methodThe control method of preset function.
Wherein, the first preset function in the embodiment of the present invention is for using fingerprint recognition to carry out to respond this first to preset meritThe application of the various operations of energy or service, such as, screenshotss function, e-book application etc..The mode of fingerprint recognition is based on above-mentioned fingerStricture of vagina identification device is carried out.
As it is shown on figure 3, in embodiments of the present invention, the fingerprint identification device of terminal can be provided with 4 kinds of mode of operations: coldScreen pattern, keystroke pattern, finger scan pattern and sleep pattern.
Wherein, 1, keystroke pattern:
Under keystroke pattern, fingerprint identification device can realize keypress function, terminal can by scanning finger touch status orPressed state, detecting finger is to press or lift, and reads according to the state notifying AP pressing or lifting of above-mentioned fingerCurrent keystroke pattern.
2, finger scan pattern:
When the first preset function using fingerprint to trigger, terminal (the specially AP of terminal) sends order or signal to fingerStricture of vagina identification device enters this pattern, it is achieved finger scan and the transmission of finger print information.Under finger scan pattern, terminal can be determinedTime Scanning Detction whether have whether finger has touch operation at Pixel Array, when detected finger carry out touch operation andMeet first pre-conditioned time, carry out finger scan (collection) and notify AP reading finger print information.
3, cold screen pattern:
Based on user behavior or the requirement of initial setting up, AP can send corresponding order, makes fingerprint identification device enter coldScreen pattern.When cold screen pattern, by the touch of finger can allow user by terminal one key unlock, i.e. terminal realize from cold screen,Wake up up, once complete to unblock.Under cold screen pattern, terminal is also timing scan to detect whether that the touch pressing of finger is graspedMaking, when having detected that finger presses for a long time and keeps stable, terminal just wakes up AP up and enters terminal by fingerprint recognitionOperating system.
4, sleep pattern:
In a sleep mode, fingerprint identification device enters low power consumpting state, after user triggers release tab, terminal wake-upAP enters into other mode of operation.
It should be noted that in embodiments of the present invention, cold screen pattern and sleep pattern are all that terminal is in screen lock stateTime the mode of operation that selects, and the mode of operation selected during keystroke pattern and finger scan pattern to be terminal be in released state.Wherein, sleep pattern colder screen pattern saves power consumption and electricity.
In embodiments of the present invention, due to by be used for carrying out the Pixel Array of fingerprint recognition and the function in terminal byKey has carried out multiplexing (such as, multiplexing is on the home key of terminal), therefore, actually used the examining of function button based on terminalConsider, when terminal is in released state or user triggers the solution latching operation of terminal, the work of the fingerprint identification device of this terminalThe initial pattern of pattern is defaulted as keystroke pattern.
It should be noted that in embodiments of the present invention, the determination of mode of operation when terminal is in released state, andThe determination of mode of operation when terminal is in screen lock state can also be configured to fingerprint identification device by microprocessor by APOperational factor determines and adjusts.
Exemplary, as shown in Figure 4, terminal arranges interface by the fingerprint recognition on UI interface, is manually entered by userThe selection of the mode of operation of terminal during row screen locking.User selects the terminal when screen locking to enter sleep pattern.
In embodiments of the present invention, owing to the mode of operation of terminal has multiple, under different mode of operations, terminal is passed throughDifferent operations realizes different functions, and when triggering solution latching operation, terminal acquiescence enters keystroke pattern, and this terminal is being pressedDuring key pattern, timing detect whether activate the first preset function.

S1011, detect whether to get touch pressing operation.
S1012, when obtain touch pressing operation and this touch pressing operation meet first pre-conditioned time, activate firstPreset function.
It should be noted that whether terminal can be by the finger of timing or periodic detection user at PixelArray has carried out carrying out on the button of multiplexing touching or pressing operation, to determine that terminal is to hold with the function button in terminalRow keypress function is also carried out fingerprint identification function.First, terminal has detected whether that people has carried out touch pressing operation to button,When detecting that user has carried out touch pressing operation to button, this touch pressing operation of terminal judges is to touch or pressing,When judging that touching pressing operation is touch operation, and when this touch operation meets the activation condition triggering the first preset function,Terminal can activate this first preset function.
Concrete, the activation condition of the first preset function can be to continue Preset Time or at Preset Time in touch operationInterior touch preset times etc..
It should be noted that after the first preset function in the embodiment of the present invention is activated, can be have been completed toFirst preset function (such as, fingerprint is opened application etc. and activated the function achieved that), it is also possible to be to activate the first preset functionSimply realize this function stepping-stone to success (such as, activate screenshotss function, fingerprint activity to be passed through carries out follow-up screenshotss screen or interiorOne class function of the selection held).Therefore, for above-mentioned the former, activate the first preset function and just have finished on whole flow process.ThisInventive embodiments is based primarily upon the latter and carries out the combination of fingerprint recognition and functional realiey.
S102, when the first preset function is activated, keystroke pattern be switched to finger scan pattern, enter according to sample rateThe collection of row the first finger print information.
A class function simply realize the stepping-stone to success of this function for activating the first preset function for, detects in terminalWhen first preset function is activated, the duty of this terminal is switched to finger scan pattern by keystroke pattern, and this terminal is being enteredEnter after finger scan pattern, begin to by Pixel Array and ADC, the fingerprint of user is acquired, obtain fingerprint letterBreath.Wherein, terminal is to carry out the collection of fingerprint according to default sample rate, preset sample rate selection rationally,Inventive embodiments is not restricted.
Exemplary, after terminal is in unblock (unlock screen) state, this terminal is according to shown in Fig. 3, and entrance is pressedKey pattern, this is not owing to activating pixel array (not activate the first preset function), so mode of operation nowThe power consumption that power consumption produces less than finger scan pattern, terminal the most only enables key touch detector part, and terminal can be everyWhether certain time (preset the very first time) scanning finger has a touch pressing operation, concrete by detection touch condition flag(up or down) judges, and notifies that AP is to read the operation information after touch.If the AP of terminal has detected that finger touchesTouching, touch condition flag is down, and starts a timer, and the persistent period of down more than 500ms (preset first timeBetween), then activate the first preset function.
It is understood that the control method of a kind of terminal provided by the embodiment of the present invention can realize long by fingerprintKey range activates and enables the first preset function.Such implementation extends the applicable model of current market fingerprint recognitionEnclose, add mode of operation more efficiently to relevant preset function, and strengthen Consumer's Experience sense.
S103, the mapping relations slided with screen of moving according to the first finger print information and preset fingerprint, it is achieved on screenFirst operation.
It should be noted that terminal is preset with user carry out cunning when fingerprint slides and on the screen of terminal in terminalCorresponding mapping relations between dynamic step-length, say, that fingerprint sliding step in terminal is mapped on the screen of terminalIt it is exactly the corresponding slip presetting step-length.
Therefore, terminal according to the first finger print information, can obtain the movement locus of the finger of user, is embodied in finger print informationIn be exactly fingerprint movement locus, and move the mapping relations slided with screen according to fingerprint movement track and preset fingerprint, it is achievedThe slide (the first operation) of the corresponding step-length on screen.
