Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In general, fingerprint unlocking schemes include: front unlocking, rear unlocking and screen unlocking. In pursuit of the screen occupation ratio of the electronic equipment, a rear unlocking scheme and a screen-down unlocking scheme are used. Due to the fact that the rear unlocking needs to occupy a part of the rear shell area of the electronic equipment, when the protective shell is installed on the electronic equipment, the aperture position on the protective shell needs to be adjusted. Therefore, compared with the rear unlocking, the screen unlocking device has a wider application prospect. The workflow of unlocking under the screen is completed from the touch operation of detecting a fingerprint identification area to the fingerprint identification, and can be divided into: fingerprint collection, fingerprint image matching and interface drawing. The fingerprint acquisition stage can be divided into preparation work and formal acquisition. Improvements can be made from these steps to reduce the overall time consumed for unlocking if the efficiency of fingerprint unlocking is to be improved.
For the fingerprint collection stage, fig. 1 is a schematic view of a process of unlocking a fingerprint under a screen, as shown in fig. 1, in the current fingerprint collection under a screen, after a finger of a user touches a fingerprint identification area on a display screen of an electronic device, a System (System) process creates a corresponding application program (APP) process for initiating a drawing instruction of a green spot and a masking layer, and initiates an instruction for drawing the green spot and the masking layer through the APP process, so that based on the instruction, a task management service (AMS) thread, a Window Management Service (WMS) thread and a layer synthesis (Surface flag) calling process cooperate to realize synthesis of an interface for collecting a fingerprint, and initiate an instruction for collecting fingerprint information after synthesis is completed; and formally collecting the fingerprints under the control of the instruction.
It should be noted that the drawing of the cyan spot is to set the fingerprint identification area on the display screen as a highlight area. The drawing of the masking layer is to add a masking layer on the area outside the fingerprint identification area on the display screen so as to reduce the brightness of the area outside the fingerprint identification area.
As described above, the preparation work is complicated at present, and the number of processes and threads involved is large, which results in a long time for the preparation work. Moreover, any involved process or thread is occupied, which results in a longer time consuming unlocking procedure.
In order to improve efficiency of fingerprint unlocking, an embodiment of the present disclosure provides an electronic device control method, fig. 2 is a first flowchart of an electronic device control method according to an exemplary embodiment, and as shown in fig. 2, the method is applied to an electronic device and includes the following steps:
The electronic device refers to an electronic device with a display screen, for example, a smartphone, a tablet computer, or a wearable electronic device.
Be provided with the fingerprint module on the electronic equipment, the fingerprint module can be push type fingerprint module or touch fingerprint module, but push type fingerprint module is the module of the physical button of pursuing fingerprint sensor integrated push type. But touch fingerprint module is the module of fingerprint sensor integrated non-push type physical button.
The system process is a memory management process of the system, has the highest priority and is used for starting the system. The layer composition process is a service process and is used for combining graphical interfaces of various application programs.
The detection of the touch operation of the fingerprint identification area corresponding to the display screen of the electronic device in step 101 may be periodic detection, that is, the detection of the fingerprint identification area is initiated once every preset time period; the detection may also be performed in real time.
In practical application, when a touch operation is detected, a touch event is generated, so that whether the touch event occurs or not can be detected to control a system process of the electronic device to call a layer composition process. The detection may be realized based on a pressure sensor or a temperature sensor under the screen, and the specific detection mode is not described herein.
As described above, in general processing, after a touch operation is detected, an application process is created by a system process of the electronic device, and then a corresponding thread is controlled by an instruction sent by the application process to control a layer composition process to implement processing. In order to improve fingerprint acquisition and/or verification efficiency, in the embodiment of the disclosure, after a touch operation is detected, a system process of the electronic device directly starts to call a layer composition process to execute processing. Therefore, processing calls of a plurality of objects in the middle are reduced, and the execution speed is increased.
Here, the system process of the electronic device calls the layer composition process, and may be: and informing the layer composition process to execute the processing by a preset thread in a system process. The preset thread may be an input system (InputReader) thread, and is configured to obtain an input event and an add/delete event on the electronic device. And after the corresponding event is acquired, calling a corresponding process to execute processing. As in the embodiments of the present disclosure, when a touch operation is detected, a touch event is generated, and then an instruction is initiated based on the touch event to invoke an image layer composition process to execute processing.
The InputREADER thread is used to listen for events from component communication (EventHub). The EventHub is used for establishing communication between any two components and realizing information transmission. The EventHub is a central processing station of all events in the system and manages all input events of the input modules which can be identified in the system; and when the input module is added or deleted, EventHub generates corresponding input events to the system. The input module includes: a microphone, a touch screen, or volume adjustment keys, etc. The InputREADER thread can monitor events from component communication (EventHub), and can read the events from the EventHub by calling getEvents () function when an input event occurs, so as to call a corresponding component to realize management.
Since the InputReader may be associated with each input module, for fingerprint unlocking in the embodiment of the present disclosure, when a touch operation on a display screen is detected, it means that an input event occurs, and then the layer composition process may be notified directly based on an InputReader thread in a system process to execute processing, and is not called indirectly through an application layer.
Fig. 3 is a flowchart illustrating a second method for controlling an electronic device according to an exemplary embodiment, and as shown in fig. 3, in this embodiment of the present disclosure, after a finger of a user touches a print recognition area on a display screen of the electronic device, a System (System) process directly calls a layer composition (Surface flag) process to perform processing. The efficiency of the unlocking of the texture is obviously improved due to the reduction of the various intermediate objects as described in fig. 1.
And after the layer composition process is called, adjusting the brightness of a first display area corresponding to the fingerprint identification area on the display screen to a first preset brightness value. Here, first preset luminance value is that the light that the display screen sent is enough for the fingerprint to reflect to the fingerprint collection module on for the fingerprint collection module can gather the luminance that generates the fingerprint image.
It should be noted that, the adjusting the brightness of the first display area to the first preset brightness value occurs when the brightness of the first display area is lower than the first preset brightness value, and when the brightness of the first display area is not lower than the first preset brightness value, the brightness may not be adjusted.
Because the fingerprint collection under the screen is based on the high-brightness light emitted by the display screen, the light irradiates the fingerprint, and the fingerprint information is collected through the reflection of the fingerprint to the light. Therefore, in order to acquire the fingerprint, the system process calls the layer composition process to increase the brightness of the area on the display screen for identifying the fingerprint, so that the acquisition of the fingerprint information can be performed based on the high-brightness light at the first display area.
The fingerprint information includes: fingerprint images or textual description information of fingerprints extracted from fingerprint images, etc.
In the embodiment of the disclosure, when a touch operation for a fingerprint identification area corresponding to a display screen of an electronic device is detected, a layer composition process is directly called by a system process of the electronic device, so that brightness of a first display area corresponding to the fingerprint identification area on the display screen is adjusted to a first preset brightness value. Therefore, the steps of firstly establishing the application program process through the system process, then calling the corresponding thread to set the brightness of the first display area based on the application program process and then calling the layer synthesis process are eliminated, and the layer synthesis process is directly called through the system process to carry out processing, so that the flow of preparation work before fingerprint image acquisition is greatly reduced, and the efficiency of fingerprint unlocking is effectively improved.
In some embodiments, the method further comprises:
the layer composition process displays a blue spot for prompting a fingerprint placement position on the first display area; the area of the cyan spot is not larger than the area of the first display region.
In the embodiment of the present disclosure, the blue spot may be displayed in a line form of a fingerprint, and is used to prompt a position where a finger for unlocking the fingerprint is placed, so that the blue spot may be circular or elliptical. In specific application, after a finger of a user is placed in a fingerprint identification area of a display screen, a first display area of the display screen corresponding to the position right below the finger can display a green spot in a fingerprint texture form.
Because the luminance in the first display area of the fingerprint identification region of display screen can adjust first predetermined brightness value to the light of the hi-lite that sends shines on the fingerprint, realizes the collection to fingerprint information through the reflection of fingerprint to light, so be used for indicateing that the blue spot of fingerprint position is placed is exactly to be located in the first display area, and the area is not more than the area of first display area, so can realize accomplishing the collection to the fingerprint in first display area.
The implementation of the layer composition process for displaying the blue speckles on the first display area may be: after touch operation of a pattern recognition area is detected, calling the layer composition process by an InputREADER thread in a system process, and informing a pattern generation assembly to send a pattern element to be displayed to the layer composition process; and the layer composition process receives the graphic elements to be displayed, synthesizes the graphic elements to be displayed and sends the synthesized graphic elements to the display screen for display.
Here, the graphic elements to be displayed include: and blue spots. In some embodiments, while the first display area displays the cyan spot, information for prompting the progress of fingerprint collection can be displayed on the cyan spot. The information prompting the fingerprint acquisition progress can be numerical value information or image information. The numerical information may be, for example, 50%, i.e., the fingerprint information is collected by half. The image information may be: and setting the collected part on the line as a preset color according to the line of the fingerprint on the green spot. The more colors preset on the cyan spot then indicate the more information that has been gathered.
So, after detecting the touch-control operation in line identification area, demonstrate the blue or green spot on first display area, can indicate the user and be carrying out fingerprint collection this moment, convenience of customers learns the purpose and the progress of operation, is favorable to improving the experience of fingerprint unblock.
It should be noted that the display screen further includes: a second display area outside the first display area.
In the embodiment of the present disclosure, the remaining regions of the display screen except for the first display region belong to a second display region.
In some embodiments, fig. 4 is a flowchart illustrating a method for controlling an electronic device according to an exemplary embodiment, where as shown in fig. 4, the method further includes:
and step 104, adjusting the brightness of the second display area to a second preset brightness value through the layer synthesis process, wherein the second preset brightness value is smaller than the first preset brightness value.
Here, if the first preset brightness value is set to facilitate fingerprint information collection in a highlight environment, the second preset brightness value is set to reduce the stimulation of high-brightness light emitted from the display screen to the eyes of the user during the fingerprint unlocking process of the user, and reduce the interference of ambient light to fingerprint collection.
As described above, in order to collect fingerprint information, the brightness of the first display area for detecting touch operation and collecting fingerprint information needs to be increased, but in practical application, only one area for collecting fingerprints on the display screen is provided, and if the whole display screen is in a highlight state in the process of collecting fingerprints, certain stimulation is caused to eyes of a user, which is not favorable for the user to feel when using the electronic device. In addition, because fingerprint information is collected by reflection of light, if strong light is emitted in the second display area, the transmission of the light may be affected to a certain extent, and fingerprint collection may be interfered. Based on this, in the embodiment of the present disclosure, after the touch operation for the fingerprint identification area corresponding to the display screen of the electronic device is detected, in addition to adjusting the brightness of the first display area to the first preset brightness value through the layer composition process, the brightness of the second display area needs to be adjusted to the second preset brightness value through the layer composition process, so as to reduce interference of surrounding light rays on fingerprint acquisition, and protect eyes of a user, so as to further improve user experience.
In some embodiments, the adjusting, by the layer composition process in the step 104, the brightness of the second display area to a second preset brightness value includes:
step 1041, setting a mask layer on the display content of the second display area through the layer composition process;
and the brightness of the second display area when the display content and the mask layer are displayed is less than or equal to the second preset brightness value.
Here, the cover layer may be a translucent element for covering some elements of a display page of the display screen so that the luminance of the some elements is reduced and the elements are in a blurred state. Then, the brightness of the second display area may be reduced by providing a mask on the display content of the second display area.
Because the display screen is a whole, the brightness of the whole display screen is changed to realize the brightness change, namely, the whole brightness is adjusted. Generally, the display screen cannot adjust the brightness of a single area, that is, the brightness adjustment of the first display area cannot be realized by independent control. Therefore, if the brightness of the first display area is adjusted to the first preset brightness value, the display brightness of the whole display screen is substantially improved, and the first preset brightness value is achieved; i.e. the display screen as a whole is in a highlighted state.
In the embodiment of the disclosure, in order to realize the brightness enhancement of the first display area and the brightness reduction of the second display area, the driving voltage of the backlight or the Organic Light-Emitting Diode (OLED) display screen is increased to realize the overall brightness enhancement of the display screen, and then the masking layer is processed to control the brightness of a single pixel at the second display area, so as to realize the brightness dimming of the second display area.
In step 103, the brightness of the first display area on the display screen is adjusted to the first preset brightness value, and substantially, the brightness of the second display area is adjusted to the second preset brightness value by arranging a masking layer on the display content of the second display area while the brightness of the display screen is adjusted to the first preset brightness value. Since there are only 2 regions on the entire display screen: a first display area and a second display area. When the brightness of the display screen is integrally adjusted to a first preset brightness value, the brightness value is reduced due to the fact that the covering layer is arranged on the second display area, and at the moment, the fingerprint information is collected through the brightness of the first display area.
In an embodiment of the present disclosure, the second preset brightness value is lower than the first preset brightness value. As mentioned above, the first preset brightness value is the brightness enough for the fingerprint to be reflected to the fingerprint collection module to collect and generate the fingerprint image. In order not to affect the fingerprint information collection and not to stimulate human eyes, the second preset brightness value may be set to be lower than the first preset brightness value, so as to reduce interference of ambient light on fingerprint collection and protect human eyes.
The embodiment of the disclosure reduces the harm to the eyes of the user while collecting fingerprint information by arranging the covering layer on the display content of the second display area.
In some embodiments, fig. 5 is a flowchart illustrating a fourth method of controlling an electronic device according to an exemplary embodiment, as illustrated in fig. 5, the method further comprising:
and 105, restoring the display brightness of each display area of the display screen after the fingerprint identification is successful.
As described above, the brightness of the first display area is adjusted to the first preset brightness value to facilitate clear and complete collection of fingerprint information. Based on this, since the display screen brightness when the user uses the electronic apparatus is the brightness before adjustment, it may be the display brightness adapted or desired by the user.
Then, after the fingerprint information is collected and the fingerprint information is successfully identified, the display brightness of each display area of the display screen can be restored to the brightness before adjustment. The brightness before adjustment is brightness of the electronic device before fingerprint unlocking of the user, and can be considered as brightness set when the user uses the electronic device last time.
It should be noted that, in actual operation, when a user performs fingerprint unlocking, the fingerprint may be dirty, or a display screen of the electronic device may be dirty, so that the electronic device may not be opened only by performing fingerprint unlocking once, that is, the fingerprint may not be successfully recognized only by performing acquisition once. At this time, the fingerprint needs to be acquired multiple times. If the display brightness of each display area of the display screen is restored after fingerprint information is collected every time, after the fingerprint information is collected once and is not identified successfully, the brightness of the first display area needs to be adjusted to be the first preset brightness value when the fingerprint information is collected again, repeated operation can not only reduce the efficiency of fingerprint unlocking, but also increase unnecessary consumption of electronic equipment due to repeated brightness adjustment.
According to the embodiment of the disclosure, after the fingerprint identification is successful, the display brightness of each display area of the display screen is restored, so that the possibility of injury to eyes of a user is reduced while the electric quantity is saved.
In an embodiment of the present disclosure, the fingerprint recognition includes:
and comparing the fingerprint information detected by the fingerprint sensor with the fingerprint information which is stored in advance and used for unlocking.
Here, if the fingerprint information detected by the fingerprint sensor matches with the fingerprint information for unlocking stored in advance, it is determined that the fingerprint identification is successful; otherwise, the fingerprint identification fails.
In this step, a manner of unlocking by fingerprint may be selected in advance: at least one fingerprint capable of being unlocked is input according to the prompt of the electronic equipment, namely, one or more fingerprints can be set as effective fingerprint information for unlocking. Then, when the collected fingerprint information matches any one of the fingerprint information for unlocking stored in advance, it is determined that the fingerprint identification is successful, and if the collected fingerprint information does not match any one of the fingerprint information, it is determined that the fingerprint identification is failed.
It should be noted that the matching here includes: completely consistent or similar degree exceeds the preset value. And when the acquired fingerprint information is matched with any one of the fingerprint information for unlocking, determining that the acquired fingerprint information is the fingerprint information capable of unlocking the electronic equipment. For example, the preset value may be set to 95%, that is, when the same portion of two fingerprints exceeds 95%, the matching is considered to be successful, that is, the fingerprint identification is successful.
In some embodiments, fig. 6 is a flowchart illustrating a method for controlling an electronic device according to an exemplary embodiment, where as shown in fig. 6, the method further includes:
and 106, after the brightness of the first display area is adjusted to the first preset brightness value, acquiring a fingerprint image through a fingerprint sensor under the display screen based on the touch operation.
As mentioned above, the acquisition of the fingerprint under the screen is based on the fact that the high-brightness light emitted by the screen lock irradiates the fingerprint, and the fingerprint image is acquired through the reflection of the fingerprint to the light. Therefore, in order to acquire the fingerprint, the system process calls the layer composition process to increase the brightness of the area on the display screen for identifying the fingerprint, so that the acquisition of the fingerprint information is performed at the first display area.
Here, after the brightness of the first display area is adjusted to the first preset brightness value, acquiring a fingerprint image by a fingerprint sensor under the display screen based on the touch operation may be: when the brightness of the first display area is detected to be adjusted to the first preset brightness value, fingerprint information is collected through a fingerprint sensor below the display screen.
Fig. 7 is a sixth flowchart of a method for controlling an electronic device according to an exemplary embodiment, where as shown in fig. 7, when a touch operation on a fingerprint identification area corresponding to a display screen of the electronic device is detected, a layer composition process is directly invoked by a system process of the electronic device according to an embodiment of the present disclosure to adjust a first display area brightness corresponding to the fingerprint identification area on the display screen to a first preset brightness value, and at the same time, adjust a second display area brightness to a second preset brightness value by the layer composition process. And fingerprint images are collected in the first display area through a fingerprint sensor under the display screen, and after the fingerprint identification is successful, the display brightness of each display area of the display screen is restored.
Therefore, the steps of firstly establishing the application program process through the system process, then calling the corresponding thread to set the brightness of the first display area based on the application program process and then calling the layer synthesis process are eliminated, and the layer synthesis process is directly called through the system process to carry out processing, so that the flow of preparation work before fingerprint image acquisition is greatly reduced, and the efficiency of fingerprint unlocking is effectively improved. In addition, the display brightness of each display area is restored after the unlocking, so that the possibility of injury to eyes of a user is reduced while the electric quantity is saved.
It should be noted that, in some embodiments, the method further includes:
after the fingerprint identification is successful, drawing an interface to be displayed through the layer synthesis process;
and after the unlocking is finished, displaying the interface to be displayed.
Here, the last locking of the display screen may be locking performed in the process of using the application software when the application software is in the on state, or locking performed when the display interface is in the system interface. Thus, the interface to be displayed includes: an interface of application software or a system interface.
According to the method and the device for unlocking the screen, the corresponding interface mode during last screen locking is displayed after unlocking is successful, a user can conveniently continue to use the last interface, time consumption for searching caused by the fact that the user needs to use the last interface is reduced, and user experience is further improved.
In some embodiments, the method further comprises:
and after the fingerprint identification fails, setting the electronic equipment to be in a screen-saving standby state.
As described above, if the fingerprint information collected by the fingerprint sensor is successfully identified, that is, it is determined that the fingerprint information is a fingerprint that can unlock the electronic device, the screen may be lit up after the unlocking is completed, and the interface of the application software or the system interface that has been drawn is displayed, thereby completing the unlocking process of the electronic device. If the fingerprint information collected by the fingerprint sensor fails to be identified, it is determined that the fingerprint information is not the fingerprint information for unlocking the electronic equipment, and the electronic equipment cannot be unlocked and lightened. Therefore, the power supply of the display screen is turned off, the electronic equipment is reset to the screen standby state, the user waits for inputting the fingerprint information again, and the steps are repeated for unlocking.
Therefore, the image layer synthesis process is directly called through the system process to carry out processing, so that the flow of preparation work before fingerprint image acquisition is greatly reduced, and the efficiency of fingerprint unlocking is effectively improved. In addition, the display brightness of each display area is restored after the unlocking is successful, so that the possibility of injury to eyes of a user is reduced while the electric quantity is saved. After the unlocking fails, the electronic equipment is set to be in a screen-turning standby state, so that the information on the electronic equipment of an unauthorized user can be prevented from being acquired, and the information protection is enhanced.
