All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terms "first," "second," "third," and "fourth," etc. in the description and claims of the invention and in the accompanying drawings are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "include" and "have," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the invention. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
The mobile terminal described in the embodiment of the present invention may include a smart Phone (such as an Android Phone, an iOS Phone, a Windows Phone, etc.), a tablet computer, a palm computer, a notebook computer, a mobile internet device (MID, mobile internet Devices), or a wearable device, which are merely examples, but not exhaustive, and include but are not limited to the mobile terminal.
In the embodiment of the present invention, the fingerprint identification module of the mobile terminal may include the following two operating modes: fingerprint collection mode and Home key mode, wherein, fingerprint collection mode includes normal entering and unblock function, and in the Home key mode, the fingerprint identification module passes through the capacitance induction and simulates pressing of Home key and leaves and produce corresponding Home incident. When the fingerprint identification module is in the Home key mode, if the unexpected electrostatic interference has been met at this time, the working state of the fingerprint identification module is likely to be abnormal, so that the function of the Home key function in a period of time is disabled, and a user can not return to the homepage of the mobile terminal by touching the Home key any more, thereby bringing about obvious bad user experience.
It should be noted that, in the embodiment of the present invention, when the fingerprint identification module is in the fingerprint collection state, that is, when the finger is waiting to be put down, the fingerprint identification module periodically scans whether the fingerprint is pressed down in a specific sensor area, if so, the fingerprint identification module generates an interrupt and notifies a main control (for example, a CPU), and a scanning period of the sensor corresponds to a scanning frequency of the fingerprint identification module, for example, the scanning period of the fingerprint identification module is 1s, and the scanning frequency is 1 HZ.
It should be noted that, in the embodiment of the present invention, when a fingerprint is pressed down in a specific sensor area of the fingerprint identification module, the fingerprint identification module compares a currently detected capacitance value with a preset capacitance threshold value in the register, and only when the current capacitance value is greater than the preset capacitance threshold value, the fingerprint identification module generates an interrupt to notify the master control.
Fig. 1 is a flowchart illustrating a method for controlling a fingerprint identification module according to a first embodiment of the present invention. The method for controlling the fingerprint identification module described in the embodiment comprises the following steps:
101. when the user touches the fingerprint identification module, detect whether the fingerprint identification module is in the Home key mode.
Wherein, when the user touched the fingerprint identification module, can detect the current mode of fingerprint identification module, the fingerprint identification module can be in the Home key mode, perhaps, fingerprint collection mode. Under the general condition, the fingerprint identification module is mostly in the Home key mode because the time that need not carry out the fingerprint unblock accounts for the majority. The mobile terminal can read the mode state of the current fingerprint identification module, if the mode state is the Home key mode, the fingerprint identification module is currently in the Home key mode, and if the mode state is the fingerprint acquisition mode, the fingerprint identification module is currently in the fingerprint acquisition mode.
Optionally, in step 101, detecting whether the fingerprint identification module is in the Home key mode may include the following steps:
11) acquiring a current application environment;
12) and detecting whether the current application environment is a preset application environment, and determining that the fingerprint identification module is in the Home key mode when the current application environment is the preset application environment.
Wherein, predetermine the application environment and can be for the application environment that need not carry out the fingerprint unblock, under the unblock state that does not need promptly, the user presses the fingerprint identification module, then can be for predetermineeing the application environment this moment, for example, not payment application environment, perhaps, not type in the fingerprint environment, perhaps, under other environment that do not need the fingerprint unblock, all can understand as belonging to and predetermine the application environment. Different applications correspond to different application environments in different use scenes. In specific implementation, the mobile terminal can acquire a current application environment, detect whether the current application environment is a preset application environment, and when the current application environment is the preset application environment, the fingerprint identification module is in a Home key mode.
102. When the fingerprint identification module is in the Home key mode, the fingerprint identification module is controlled to work by using a first scanning frequency and a first capacitance threshold value.
The first scanning frequency and the first capacitance threshold value can be set by default of a system or by a user. When the fingerprint identification module is in the Home key mode, the fingerprint identification module can work with this first scanning frequency and first electric capacity threshold value.
103. And when the fingerprint identification module is not in the Home key mode, controlling the fingerprint identification module to work by using a second scanning frequency and a second capacitance threshold, wherein the second scanning frequency is greater than the first scanning frequency, and the second capacitance threshold is smaller than the first capacitance threshold.
Wherein, when the fingerprint identification module is not in the Home key mode, explain that the fingerprint identification module is in the fingerprint collection mode, under this fingerprint collection mode, need higher scanning frequency for wait for the fingerprint image of gathering user's finger. The second scanning frequency is greater than the first scanning frequency, and the second capacitance threshold value is smaller than the first capacitance threshold value. So, under the fingerprint collection mode, can let the fingerprint identification module more sensitive, and under the Home key mode, can reduce the sensitivity of fingerprint identification module, so, not only can realize preventing the mistake and touching under the Home key mode, can also reduce mobile terminal's consumption to a certain extent.
Optionally, in step 103, controlling the fingerprint identification module to operate using a second scanning frequency and a second capacitance threshold may include the following steps:
and controlling the fingerprint identification module to work by using a second scanning frequency and a second capacitance threshold value within a preset time period, wherein the second scanning frequency presents a decreasing trend in the preset time period, and the second capacitance threshold value presents an increasing trend in the preset time period.
The preset time period can be set by the user or defaulted by the system. For example, the preset time period may be a period from when the user touches the fingerprint recognition module to when the user leaves the fingerprint recognition module. The second scanning frequency can be a dynamic variation, and at the time of presetting, along with the lapse of time axis, progressively decrease, the second electric capacity threshold value can be a dynamic variation, at the time of presetting, along with the lapse of time axis, progressively increase up gradually, so, under fingerprint collection mode, if the fingerprint identification module is touched for a long time, then can reduce mobile terminal's consumption.
Optionally, in step 103, controlling the fingerprint identification module to operate using a second scanning frequency and a second capacitance threshold may include the following steps:
31) when the current position is a preset position, detecting whether the current application environment is a payment application environment;
32) and when the current application environment is a payment application environment, determining the second scanning frequency and the second capacitance threshold according to the corresponding relation between the preset application and the scanning frequency and the capacitance threshold, and executing the control of the fingerprint identification module to work by using the second scanning frequency and the second capacitance threshold.
In step 31, the mobile terminal may determine the current location of the mobile terminal through a Global Positioning System (GPS), or the mobile terminal may determine the current location of the mobile terminal through a Wireless Fidelity (Wi-Fi) Positioning technology. The current location of the mobile terminal may be expressed in terms of latitude and longitude, for example, the current location may be expressed as 113 ° 46 'east longitude and 22 ° 27' north latitude. The preset position can be a supermarket, a restaurant, a hotel, a railway station, an airport and the like. In the embodiment of the invention, the corresponding relation between the application and the scanning frequency and the capacitance threshold value can be preset, so that the scanning frequency and the capacitance threshold value corresponding to the application environment can be directly obtained through judging the application environment, and when the current application environment is a payment application environment, the second scanning frequency and the second capacitance threshold value corresponding to the current application environment can be directly obtained, and therefore, the fingerprint identification module can be controlled to work by using the second scanning frequency and the second capacitance threshold value.
It can be seen that, according to the embodiment of the present invention, when a user touches the fingerprint identification module, whether the fingerprint identification module is in the Home key mode is detected, when the fingerprint identification module is in the Home key mode, the fingerprint identification module is controlled to operate by using the first scanning frequency and the first capacitance threshold, and when the fingerprint identification module is not in the Home key mode, the fingerprint identification module is controlled to operate by using the second scanning frequency and the second capacitance threshold, wherein the second scanning frequency is greater than the first scanning frequency, and the second capacitance threshold is smaller than the first capacitance threshold. So, under Home key mode, the fingerprint identification module is difficult to be touched by the mistake, simultaneously, under fingerprint collection mode, the fingerprint identification module also can the sensitive fingerprint image of gathering.
In accordance with the above, please refer to fig. 2, which is a flowchart illustrating a method for controlling a fingerprint recognition module according to a second embodiment of the present invention. The method for controlling the fingerprint identification module described in the embodiment comprises the following steps:
201. when the user touches the fingerprint identification module, whether the mobile terminal is in a charging state is detected.
The mobile terminal may perform status monitoring to determine whether it is in a charging state, and may perform step 202 when it is not in the charging state. While it is in the charging state, step 202 may not be performed. The mobile terminal can detect whether external current is connected, and if so, the mobile terminal is in a charging state.
202. And when the mobile terminal is not in a charging state and the current electric quantity of the mobile terminal is lower than a preset threshold value, detecting whether the fingerprint identification module is in a Home key mode.
The preset threshold value can be set by the user, or the system defaults. When the mobile terminal is in a charging state and a current electric quantity prison preset threshold value, whether the fingerprint identification module is in a Home key mode or not is detected, and therefore power consumption of the mobile terminal can be reduced to a certain degree.
203. When the fingerprint identification module is in the Home key mode, the fingerprint identification module is controlled to work by using a first scanning frequency and a first capacitance threshold value.
204. And when the fingerprint identification module is not in the Home key mode, controlling the fingerprint identification module to work by using a second scanning frequency and a second capacitance threshold, wherein the second scanning frequency is greater than the first scanning frequency, and the second capacitance threshold is smaller than the first capacitance threshold.
In the above steps 203-204, the corresponding steps of the method for controlling a fingerprint identification module described with reference to fig. 1 can be used, and are not described herein again.

In general, RF circuit 510 includes, but is not limited to, an antenna, at least one amplifier, a transceiver, a coupler, a Low Noise Amplifier (LNA), a duplexer, and the like. In addition, RF circuit 510 may also communicate with networks and other devices via wireless communication. The wireless communication may use any communication standard or protocol, including but not limited to global system for Mobile communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA), Wideband Code Division Multiple Access (WCDMA), Long Term Evolution (LTE), email, Short Messaging Service (SMS), and the like.
The memory 520 may be used to store software programs and modules, and the processor 580 executes various functional applications and data processing of the mobile phone by operating the software programs and modules stored in the memory 520. The memory 520 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the cellular phone, and the like. Further, the memory 520 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.
The input unit 530 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the cellular phone. Specifically, the input unit 530 may include a touch panel 531 and other input devices 532. The touch panel 531, also called a touch screen, can collect touch operations of a user on or near the touch panel 531 (for example, operations of the user on or near the touch panel 531 by using any suitable object or accessory such as a finger or a stylus pen), and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 531 may include two parts, a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, and sends the touch point coordinates to the processor 580, and can receive and execute commands sent by the processor 580. In addition, the touch panel 531 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 530 may include other input devices 532 in addition to the touch panel 531. In particular, other input devices 532 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display unit 540 may be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 540 may include a display panel 541, and optionally, the display panel 541 may be configured in the form of a Liquid Crystal Display (LCD), an Organic Light-Emitting Diode (OLED), or the like. Further, the touch panel 531 may cover the display panel 541, and when the touch panel 531 detects a touch operation on or near the touch panel 531, the touch panel is transmitted to the processor 580 to determine the type of the touch event, and then the processor 580 provides a corresponding visual output on the display panel 541 according to the type of the touch event. Although the touch panel 531 and the display panel 541 are shown as two separate components in fig. 5 to implement the input and output functions of the mobile phone, in some embodiments, the touch panel 531 and the display panel 541 may be integrated to implement the input and output functions of the mobile phone.

The audio circuit 560 may transmit the electrical signal converted from the received audio data to the speaker 561, and convert the electrical signal into a sound signal by the speaker 561 for output; on the other hand, the microphone 562 converts the collected sound signals into electrical signals, which are received by the audio circuit 560 and converted into audio data, which are then processed by the audio data output processor 580, and then passed through the RF circuit 510 to be sent to, for example, another cellular phone, or output to the memory 520 for further processing.
WiFi belongs to short distance wireless transmission technology, and the mobile phone can help the user to send and receive e-mail, browse web pages, access streaming media, etc. through the WiFi module 570, which provides wireless broadband internet access for the user. Although fig. 5 shows the WiFi module 570, it is understood that it does not belong to the essential constitution of the handset, and can be omitted entirely as needed within the scope not changing the essence of the invention.
The processor 580 is a control center of the mobile phone, connects various parts of the entire mobile phone by using various interfaces and lines, and performs various functions of the mobile phone and processes data by operating or executing software programs and/or modules stored in the memory 520 and calling data stored in the memory 520, thereby performing overall monitoring of the mobile phone. Alternatively, processor 580 may include one or more processing units; preferably, the processor 580 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into processor 580.
