Description

A flashlight control method for an intelligent mobile terminal

technical field

The invention relates to the field of smart mobile terminals such as mobile phones, personal digital assistants (PDAs), and tablet computers, and in particular to a flashlight control method for smart mobile terminals.

Background technique

Because smart mobile terminals are often carried by people, most of the smart mobile terminals currently on the market are equipped with a flashlight function to facilitate users to walk or read in the dark.

In the prior art, there are generally two methods for controlling a flashlight of an intelligent mobile terminal. A user activates the flashlight function of his mobile smart terminal by pressing or holding down a specific keypad for a long time. This method is widely used in smart mobile terminals with physical keyboards at the end of the 20th century and the beginning of the 21st century. In this method, a certain key is designated as the key for turning on the flashlight. When it is detected that the user presses the designated key, or when the designated key is pressed for a long time in order to distinguish ordinary keys, the flashlight installed in the mobile terminal is turned on. The lighting element of the flashlight. Publication number is CN201178438 Chinese patent discloses this kind of method in detail. Accompanying drawing 1 shows an example of the mobile terminal of this kind of method. The technical solution of this patent application can turn on and off the lighting device 2 in the mobile phone 1 by pressing and releasing the button 3 respectively when the button is locked, that is to say, without unlocking. However, if this method is applied to the currently widely popular large-screen touch screen intelligent mobile terminal, it will bring inconvenience. Large-screen touch-screen smart mobile terminals generally only have one or two physical buttons, and some touch-screen terminals do not even have buttons.

In another method for controlling the flashlight of a smart mobile terminal in the prior art, when the user desires to turn on the flashlight function of the smart mobile terminal, the screen needs to be unlocked and authenticated by technologies such as sliding bar or fingerprint recognition, and then the user can run the flashlight function. The application program for connecting the embedded lighting device of the smart mobile terminal, so as to finally turn on the flashlight function of the smart mobile terminal. The application number CN200880108306.1 submitted by Apple Inc. discloses a technology for unlocking or authenticating using technologies such as sliding bars or fingerprint recognition. FIG. 2 shows a schematic diagram of an exemplary electronic device display screen for detecting a user's fingerprint in one embodiment of the Chinese patent application. Display 600 includes screen 602 that instructs a user to unlock the electronic device. For example, screen 602 includes box 610 with an arrow directing the user to slide box 610 along trajectory 612 to unlock the electronic device, eg, by placing a finger on box 610 and dragging the finger along trajectory 612 . To authenticate the user during the unlocking process, display 600 may include sensor 620 in the display along trace 612 . For example, sensor 620 may be embedded in a display stack (eg, within a display stack that includes a capacitive sensing component, a light source, and a display surface). As another example, sensor 620 may be placed under the display stackup. As another example, sensor 620 may include existing components of a display stackup (eg, the display stackup of a touch screen display may include a capacitive sensor). In this example, the verification system can use the detection output of a capacitive sensing component of a display stackup (e.g., in a touchscreen display) with sufficient resolution to distinguish between ridges and valleys of the user's skin; Capacitive sensing components may include several types or densities of capacitive sensing components to facilitate verification using specific portions of the display screen (e.g., using very fine sensing elements along at least a portion of trace 612 in the display stackup for verification purposes). sensing components, and less delicate sensing components in the remainder of the display 600); the sensor 620 may be embedded in the electronic device such that the sensor 620 is not visible in the display 600, for example, the sensor 620 may be assembled, printed or etched directly on the display 600 (eg, etched on glass) so that the user cannot see the fingerprint scanner. If the user has difficulty providing a proper fingerprint to the sensor 620, the display 600 may highlight the outline of the sensor 620 (e.g., display an icon that instructs the user to place a finger on the icon above the sensor 620) to assist the user in authentication .

In the above-mentioned method of unlocking and authenticating the screen by technologies such as sliding bar or fingerprint identification, and then running the application program for connecting the embedded lighting device of the smart mobile terminal to finally enable the flashlight function of the smart mobile terminal, It is fully considered that electronic devices such as mobile terminals and notebooks often store personal or office private information, so fingerprint authentication is required before users are allowed to unlock the screen and access various applications in the mobile terminal. However, this method requires the user to perform more than two operations (first unlock the screen by sliding, and then run the flashlight program) to complete the function of turning on the flashlight of the smartphone terminal. In particular, when the position of the sliding operation for screen unlocking and the fingerprint recognition position for user identity authentication are not in the same position, or when it is necessary to switch the desktop to open the application program of the embedded lighting device of the smart mobile terminal, the user It is even necessary to perform three or more operations to use the flashlight function of the smart mobile terminal. In addition, because in this method, when unlocking the screen and swiping the fingerprint, the screen needs to be turned on first, and when the user wants to use the flashlight function of the smart mobile terminal, it is often expected to save limited power so that the lighting can last longer, so this This method has brought the distress of electricity consumption to the user.

detailed description

The implementation of the present invention will be described in detail below in conjunction with the accompanying drawings and examples, so as to fully understand and implement the process of how to apply technical means to solve technical problems and achieve technical effects in the present invention. It should be noted that, as long as there is no conflict, each embodiment and each feature in each embodiment of the present invention can be combined with each other, and the formed technical solutions are all within the protection scope of the present invention.

In addition, the steps shown in the flow diagrams of the figures may be performed in a computer system, such as a set of computer-executable instructions, and, although a logical order is shown in the flow diagrams, in some cases, the sequence may be different. The steps shown or described are performed in the order herein.

Before describing the embodiment according to the present invention, first explain the process of using fingerprints to perform authority authentication and access application programs in the prior art (Chinese patent application CN200880108306.1). The process starts at step 1502 . In step 1504, the user identification process is performed. Specifically, the smart mobile terminal (device) can use the fingerprint sensor to seamlessly capture fingerprint information for authority authentication, so as to identify the user currently using the smart mobile terminal. In step 1506, it is determined whether a request to access a restricted resource is received. For example, it is determined whether the user has provided an instruction to access data (eg, address book list or other personal information) related to the specific user. For another example, it is determined whether the user provides an instruction to access a restricted application (for example, restricted to users of a specific level, such as an administrator's application, or an application purchased by a specific user). If it is determined that an instruction to access the restricted resource has not been received, then process 1500 returns to step 1506 and continues to monitor for input received from the user. At step 1506 , if it is determined that an instruction to access a restricted resource has been received, process 1500 may proceed to step 1508 . In step 1508, it is further judged according to the authority authentication result in step 1504 whether to authorize the identified user to access the resource. In this way, the smart mobile terminal can receive appropriate authentication information without the user's knowledge, such as embedding a fingerprint sensor into the device so that the authentication information is received during normal use. If it is determined that the identified user is not authorized, then enter step 1510 . At step 1510, the user may be instructed to authenticate. At step 1508, if it is determined that the user is authorized, then process 1500 may proceed to step 1512. At step 1512, the user may be provided access to the requested restricted resource. For example, a user may be provided with access to personal data, or to applications specific to that user. Processing then ends at step 1514 .

In step S1504 of the above-mentioned prior art, when the user fingerprint is received, the user identification process of the device is performed indiscriminately, which will cause the execution of each step in FIG. 3 to run any application.

FIG. 4 shows various steps of enabling the flashlight function of the smart mobile terminal according to the processing steps in FIG. 3 above. Start from step 1602, enter steps 16041 and 16042, receive the fingerprint input by the user and identify the current user using the smart mobile terminal, then perform step S1605, perform screen display operations such as turning on the power of the display screen and unlocking the screen, otherwise the user cannot Click to send a resource access request. Entering step 1606 , the user clicks on the flashlight application, and the smart mobile terminal judges whether the access request of the flashlight application sent by the user through the click operation is received, and if the judgment result is yes, then enters step 1608 . In step S1608, determine whether to authorize the current user identified in step S1602. Since any user is generally allowed to use the flashlight application of the smart mobile terminal, it is determined in step 1608 that the current user identified in step 1602 is allowed to access the flashlight application, and then enter step 1612 To turn on the lighting part of the smart mobile terminal, that is, to turn on the flashlight.

This will lead to, for example, when the user expects to run the flashlight application in the smart mobile terminal, he needs to first input the fingerprint for authority authentication in step S1604, and then click the flashlight application in step S1606 to send a resource access request, and then the smart The mobile terminal turns on the flashlight function by executing steps S1608 and S1612. This will cause the user to perform two input operations (fingerprint input and click on the flashlight application) to enable the flashlight function, which also makes the processing of the device more complicated.

The inventors of the present invention noticed that the prior art ignores the use requirements of flashlight applications for device resources and the requirements of other applications for device resources, and proposed a flashlight control method that is more in line with people's usage habits, saves energy consumption, and even makes processing easier .

The first embodiment of the present invention will be described in detail below with reference to FIG. 5 .

Starting from step 501, the flashlight is generally turned off at this time, that is, the lighting component of the smart mobile terminal is not turned on. When the user places a finger on the sensing area of the fingerprint sensor embedded in the smart mobile terminal for acquiring the user's fingerprint, enter step 502 .

In step 502, the fingerprint input by the user through the fingerprint sensor embedded in the smart mobile terminal is acquired.

In step 503, the smart mobile terminal judges whether the acquired fingerprint matches the pre-stored preset fingerprint corresponding to the flashlight application in the smart terminal.

Preferably, when the user runs the flashlight application for the first time, the user may be prompted to input a fingerprint and the input fingerprint is saved as a preset fingerprint corresponding to the flashlight application. In this way, it has better user-friendliness than configuring the preset fingerprint corresponding to the flashlight application by the user according to the instructions. More preferably, the left-handed user can be prompted to input the fingerprint of the right hand and the right-handed user can input the fingerprint of the left hand, so as to prevent the user from mistakenly turning on (turning on) the flashlight of the smart mobile terminal when holding the mobile phone, thereby improving user satisfaction.

If the judgment result of step 503 is yes, that is, it is judged that the acquired fingerprint matches the preset fingerprint corresponding to the flashlight application, then go to step 506 . In step 506, execute the flashlight application to turn on the lighting part of the smart mobile terminal without performing user identification processing and turning on the screen processing, and turn on the lighting part in the smart mobile terminal by executing the flashlight application installed in the smart mobile terminal, to turn on the flashlight.

Otherwise, if the judgment result of step 503 is no, that is, it is judged that the fingerprint obtained does not match the preset fingerprint corresponding to the flashlight application, then the touch screen of the smart mobile terminal is connected in step 504 and other matching processing and processing of step 505 are performed. /or user identification processing.

Different from the prior art that detects the presence of any application of the smart mobile terminal and then performs user identification processing, the present invention judges that the preset fingerprint corresponding to the application used to connect the lighting components of the smart mobile terminal and the acquired When the fingerprint matches, the flashlight application for turning on the lighting part of the smart mobile terminal is executed without performing user identification processing and turning on the screen processing. When the fingerprints do not match, turn on the touch screen of the smart mobile terminal before performing other fingerprint matching processes. This not only simplifies the processing complexity of the system, but also facilitates the user to safely lend the mobile phone that has not passed the authorization authentication to a partner in the same industry, thereby improving user satisfaction.

In step 505, perform other fingerprint matching processing except the fingerprint matching processing in step S504, that is, perform matching judgment between the acquired fingerprint and other pre-stored fingerprints in the smart mobile terminal except the fingerprint corresponding to the flashlight application processing. When a matching fingerprint is found, processing corresponding to the matching fingerprint is performed.

More specifically, for example, in step 505, the acquired fingerprint can be matched with the fingerprint used to identify the user's identity, and when it is determined to match, the processing corresponding to the matched fingerprint is performed, that is, the smart mobile terminal is identified The current user (referred to as user identification processing), when it is determined to be a mismatch, the user can be prompted to authenticate before touching the screen. In this way, when a user accesses an application in the smart mobile terminal, it can be determined whether the current user has the right to access the application.

Preferably, in step 505, fingerprint matching processing for one or more applications other than the flashlight application may also be performed. More specifically, the user can pre-input fingerprints corresponding to other applications through the fingerprint sensor embedded in the smart mobile terminal and store these fingerprints in the smart mobile terminal in advance. The fingerprints acquired in are matched with the fingerprints corresponding to other applications except the flashlight application one by one until a fingerprint matching the acquired fingerprint is found or until the matching is completed for all fingerprints corresponding to other applications. In this way, if there is a fingerprint matching the acquired fingerprint, the processing of the fingerprint corresponding to the matching fingerprint is to run the application corresponding to the matching fingerprint. If no application other than the flashlight application corresponding to the acquired fingerprint is found, the desktop of the smart mobile terminal may be displayed without running any application.

In this way, different from the technical scheme of matching the acquired fingerprints with the fingerprints corresponding to the flashlight application that does not need to use the display screen and other applications that need to use the display screen one by one without distinction, the present invention will not need to turn on the screen to process To distinguish the flashlight application from other applications that need to be connected to the screen, first judge whether the acquired fingerprint matches the fingerprint corresponding to the flashlight application, and only when there is no match, other fingerprint matching processing is performed, so that It can speed up the response time of the flashlight application of the smart mobile terminal.

It should be emphasized that, according to the above, step 503 of the present invention is set to be executed before step 504 to step 505, that is, when it is determined that the preset fingerprint corresponding to the flashlight application used to turn on the lighting component of the smart mobile terminal and When the acquired fingerprints match, the lighting part application for turning on the smart mobile terminal is executed without performing user identification processing and turning on screen processing. In this way, compared with the prior art in which the screen display is turned on when a fingerprint for authentication or a fingerprint matching a certain application is detected, it saves the trouble caused by turning on the display screen of the smart mobile terminal unnecessarily. Waste of power.

In addition, in order to improve the accuracy of fingerprint matching, the data volume of fingerprint information is generally large, so the amount of matching computation between two fingerprint information is also relatively large. If the display screen is accepted after all the fingerprints are matched, the user will feel that the response speed of the smart mobile terminal is too slow. If the screen display is performed before judging whether it is matched with the flashlight application that does not need the screen display, it will cause waste of electricity. The present invention distinguishes the flashlight application that does not require screen-on processing from other applications that require screen-on processing, and when it is determined that the acquired fingerprint does not match the flashlight application that does not require screen-on processing, the Before obtaining fingerprints and performing other fingerprint matching processes such as user identification and other application matching, except for matching fingerprints corresponding to the flashlight application, the processing of turning on the screen is performed first, so that it saves unnecessary turning on the display screen. In addition, it can turn on the display screen as soon as possible to reduce the screen display delay caused by the user's fingerprint information matching processing.

Preferably, when no matching fingerprint is found after performing all the other fingerprint matching processes, the user is presented with information about the need to input fingerprints to obtain access rights.

Another preferred embodiment of the present invention will be described below with reference to FIG. 6 . Fig. 6 shows the flashlight control method of the smart mobile terminal according to this embodiment. For ease of description, steps in FIG. 6 that are substantially the same as those in FIG. 5 will be given the same reference numerals as in FIG. 5 . The difference between this embodiment and the embodiment shown in FIG. 5 will be mainly described below.

FIG. 6 further includes step 607 and step 608 . In this way, when it is determined in step 503 that the fingerprint acquired in step 502 matches the fingerprint corresponding to the flashlight application, steps 607 and 608 are further executed to disconnect the screen of the smart mobile terminal and when it is determined that there is currently an authorized user Cancel the authorization of the authorized user, so that the user cannot use the smart mobile terminal for confidential data and the like. If the current smart mobile terminal is in the screen-off (power-off) state, then maintain the current state; otherwise, switch the screen (usually a touch screen) from the on (power-on) state to the off (power-off) state.

The order of step 505 and steps 607 and 608 can be exchanged. However, preferably, step 607 is placed before step 608, and a message that the authority of the previously authorized user has been canceled is displayed in step 607, so that the user can better understand the rich functions of the smart mobile terminal to improve user satisfaction .

In this way, by further turning off the screen and/or canceling authorized user permissions, the user's data can be further enhanced to be more confidential, and the user's expectations can be better met, so that the user can safely borrow the mobile phone with passers-by When used as a flashlight, thus improving user satisfaction.

In addition, the user can also turn off the flashlight by inputting the fingerprint corresponding to the flashlight application again. Specifically, when the smart mobile terminal has already run the flashlight application, if the smart mobile terminal acquires a fingerprint corresponding to the flashlight application through the fingerprint sensor, then close the flashlight application. Fig. 7 shows a control flowchart of closing the flashlight application of the smart mobile terminal according to an implementation of the present invention.

Steps in FIG. 7 that are substantially the same as in FIG. 5 will be given the same reference numerals as in FIG. 5 . The difference between the embodiment shown in FIG. 7 and that shown in FIG. 5 will be mainly described below.

In step 701, the flashlight application of the smart mobile terminal is running, the lighting component has been connected, and the flashlight is turned on.

In step 502, the fingerprint sensor embedded in the smart mobile terminal for acquiring the user's fingerprint acquires the fingerprint input by the user.

In step 503, the smart mobile terminal judges whether the acquired fingerprint matches the pre-stored preset fingerprint corresponding to the flashlight application in the smart terminal, and if it is judged to match, then enters step 705 to turn off the lighting components of the smart mobile terminal. If it is judged not to match, then enter step 707 to further perform other matching processing to judge whether there are other pre-existing fingerprints in the smart mobile terminal that match the acquired fingerprint.

If it is determined in step 707 that there is no matching fingerprint, then enter step 705 to turn off the lighting component of the smart mobile terminal. In this way, anyone can turn on the screen and turn off the flashlight. On the contrary, if it is determined in step 707 that there is a fingerprint matching the acquired fingerprint, then enter step 708 to perform processing corresponding to the matched fingerprint.

In the embodiment shown in Figure 7, if the judgment result of step 503 is yes and the flashlight is in the off state, the flashlight application is executed to turn on the lighting component of the smart mobile terminal; if the judgment result is yes and the flashlight is in the on state , then disconnect the lighting components of the smart mobile terminal. This not only makes it convenient for the user to turn on the flashlight quickly, but also makes it convenient for the user to turn off the flashlight conveniently.

Further, step 705 is preferably, when the flashlight is turned on, if the judgment result in step 503 is yes, then the lighting part of the smart mobile terminal is not turned off until the user continues to input the fingerprint operation for a predetermined period of time, so as to prevent the user from accidentally Be careful of placing your fingerprint on the sensing area of the fingerprint sensor by mistake.

The fingerprint sensor used to acquire fingerprints in the present invention can be set in, near, or behind any button of the smart mobile terminal or other physical input that the user can press (for example, after area 620 in FIG. 2 ). For example, a fingerprint sensor can be placed on the home button (home button) of a portable media player or cell phone. button) after. A fingerprint sensor may be placed between an outer cover or surface (eg, a glass or plastic surface) and a mechanical component that operates to interface with a switch or electronic circuit. For example, a fingerprint sensing mechanism can be embedded under a transparent surface through which the sensing mechanism can detect the ridges and valleys of a user's fingerprint.

In addition, the present invention may also include a pressure sensor for sensing pressure. When the flashlight of the smart mobile terminal is turned on, the flashlight application of the smart mobile terminal adjusts the brightness of the flashlight according to the pressure sensed by the pressure sensor. In this way, compared with the prior art, the brightness of the flashlight can be changed without turning on the display screen of the smart mobile terminal, which not only saves power consumption but also facilitates operation. In addition, the "application" or "application program" herein refers not only to an application presented to a user as an icon or an executable file, but also to a script file run by an operating system or an application program as a command.

Although the embodiments disclosed in the present invention are as above, the described content is only an embodiment adopted for the convenience of understanding the present invention, and is not intended to limit the present invention. Anyone skilled in the technical field to which the present invention belongs can make any modifications and changes in the form and details of the implementation without departing from the spirit and scope disclosed by the present invention, but the patent protection scope of the present invention, The scope defined by the appended claims must still prevail.
