Wherein the object-level compression is an independent compression of each object to be compressed in the first memory, e.g. an independent compression of each group of pixel data in the first pixel data set.

Object-level decompression is to decompress each compressed object independently, rather than decompressing the entire file; for example, each group of pixel data in the first set of pixel data is decompressed independently.

In the method, the object-level compression technology is adopted to compress the first pixel data set, so that finer granularity compression control can be realized, the compression efficiency and performance are improved, the storage space of the first pixel data set on the first memory is reduced, and the size of data in the transmission process is reduced.

Further, since the first pixel data set in the first memory is data subjected to object-level compression, object-level decompression of the first pixel data set in the first memory is required.

Detailed Description

In the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a alone, a and B together, and B alone, wherein a, B may be singular or plural. The character "/" generally indicates that the context-dependent object is an "or" relationship. "at least one of" or the like means any combination of these items, including any combination of single item(s) or plural items(s). For example, at least one (one) of a, b, or c alone may represent: a alone, b alone, c alone, a combination of a and b, a combination of a and c, b and c, or a combination of a, b and c, wherein a, b, c may be single or plural. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

The fingerprint identification technology has the advantages of high safety, high identification speed, high identification success rate and the like, so the fingerprint identification technology has been widely applied to various scenes.

For example, the fingerprint identification technology can be applied to a scene of fingerprint unlocking of the electronic device, and in the fingerprint unlocking scene, the identity of the user can be identified through the fingerprint identification technology.

When the fingerprint identification technology can be applied to a fingerprint unlocking scene, the fingerprint of a user needs to be acquired through a fingerprint sensor, and the fingerprint sensor can be positioned at the back, the side edge or the lower part of a display screen of the electronic equipment.

When the fingerprint sensor is positioned below the display screen of the electronic equipment, a user can place a finger in a fingerprint identification area on the display screen, fingerprint images of the user are collected through the fingerprint sensor and are matched with the pre-stored fingerprint images to realize fingerprint unlocking, and the electronic equipment can be changed into a bright screen unlocking state from a screen locking state after unlocking.

The fingerprint identification area on the display screen is an area where the display screen is electrically connected with the fingerprint sensor.

Specifically, the screen locking state may be a screen locking state of screen extinction or a screen locking state of screen brightness.

The display screen of the electronic device can display date, time and other information.

In the process of fingerprint identification, a corresponding fingerprint unlocking moving effect picture can be displayed on a display screen of the electronic equipment, and the fingerprint unlocking moving effect picture can be also called as fingerprint unlocking moving effect.

The fingerprint unlocking moving effect picture not only can remind the user that the fingerprint is successfully read and the electronic equipment is verifying and matching the fingerprint information of the fingerprint image, but also can provide visual interaction for the user, so that the fingerprint unlocking process is more visual and pleasant, and the perception of the user on the safety and convenience of the electronic equipment is enhanced.

The fingerprint unlocking moving effect picture corresponds to a fingerprint moving effect picture, and the fingerprint moving effect picture is stored in a memory 1 in the electronic equipment in advance.

In one possible implementation manner, for an electronic device in a screen locking state, after a user places a finger in a fingerprint identification area on a display screen, a fingerprint sensor under the display screen may receive a contact operation, so that, as shown in S111-S114 in the embodiment shown in fig. 1, a fingerprint service module in an application Framework (FWK) layer registers a monitoring fingerprint function on a fingerprint identification trusted application module of a secure execution environment system through a fingerprint identification module of a hardware abstraction layer, and then, as shown in S115 in the embodiment shown in fig. 1, the fingerprint service module acquires a fingerprint moving effect picture from a memory 1 of the electronic device, and decodes the fingerprint moving effect picture to obtain fingerprint moving effect pixel data, and then, as shown in S116 in the embodiment shown in fig. 1, the fingerprint service module stores the fingerprint moving effect pixel data in a memory 2; after receiving the identification message, the fingerprint service module obtains the fingerprint moving effect pixel data from the memory 2 as shown in S117-S118 in the embodiment shown in fig. 1, and S120, and the fingerprint service module displays a fingerprint unlocking moving effect screen according to the fingerprint moving effect pixel data as shown in S121 in the embodiment shown in fig. 1.

In addition, after the user places the finger in the fingerprint identification area on the display screen, as shown in S119 in the embodiment shown in fig. 1, the fingerprint sensor may also collect a fingerprint image and send the fingerprint image to the fingerprint identification trusted application module, so that, as shown in S122 in the embodiment shown in fig. 1, the fingerprint identification trusted application module matches the collected fingerprint image with a pre-stored fingerprint image, and after the matching is finished, as shown in S123 and S124 in the embodiment shown in fig. 1, the fingerprint identification trusted application module sends a fingerprint identification result to the fingerprint service module; as shown in S125 in the embodiment shown in fig. 1, if the fingerprint identification result indicates that the fingerprint identification is successful, the electronic device is successfully unlocked, and after the unlocking is successful, the electronic device is in an unlocked state, and the fingerprint service module deletes the fingerprint effective pixel data stored in the memory 2.

After the electronic device is turned off, as shown in S126 in the embodiment of fig. 1, the fingerprint service module obtains a fingerprint moving effect picture from the memory 1 of the electronic device, and decodes the fingerprint moving effect picture to obtain fingerprint moving effect pixel data, and then, as shown in S127 in the embodiment of fig. 1, the fingerprint service module stores the fingerprint moving effect pixel data in the memory 2.

The fingerprint moving effect picture comprises a plurality of pictures, fingerprint moving effect Pixel data comprises a plurality of groups of Pixel data, one picture corresponds to one group of Pixel data, namely bitmap (bitmap) data, and one group of Pixel data comprises a grid or matrix formed by pixels (pixels).

Thus, as can be seen in conjunction with fig. 2, after the electronic device is started or restarted, the function of monitoring the fingerprint can be registered, the fingerprint moving effect picture is obtained from the memory 1 of the electronic device, the fingerprint moving effect picture is decoded, the fingerprint moving effect pixel data obtained by decoding is stored in the memory 2, after the fingerprint sensor receives the contact operation, the moving effect picture can be displayed according to the fingerprint moving effect pixel data in the memory 2, the display is finished, after the fingerprint is successfully unlocked, the fingerprint moving effect pixel data is deleted, and after the screen is removed, the fingerprint moving effect picture is obtained from the memory 1 of the electronic device again, and the fingerprint moving effect picture is decoded; in this way, the power consumption of the electronic device is increased, as well as the consumption of the electric power.

In view of the above problems, the present application may provide a moving-effect picture display method, an electronic device, a chip system, a computer-readable storage medium, and a computer program product, which may acquire a fingerprint moving-effect picture from a memory 1 in advance after registering a listening fingerprint function, decode the fingerprint moving-effect picture, store the decoded fingerprint moving-effect picture in a memory 2, display a moving-effect picture according to fingerprint moving-effect pixel data when the electronic device receives an identification message, and not delete the fingerprint moving-effect pixel data in the memory 2 after the display is completed; after the electronic equipment is turned off, repeated decoding processing is not needed to be carried out on the fingerprint moving effect picture; therefore, repeated decoding can be avoided, when fingerprint motion effect pixel data is needed to be used next time, the fingerprint motion effect pixel data can be directly obtained from the memory 2, decoding time and electric quantity of the electronic equipment can be saved, and power consumption of the electronic equipment is reduced.

The dynamic effect picture display method can be applied to electronic equipment with a fingerprint unlocking function. The electronic device may be an electronic device with display screen hardware and corresponding software support.

For example, the site device may be a cell phone, tablet computer, in-vehicle device, notebook computer, wearable device, ultra-mobile personal computer (UMPC), netbook, personal digital assistant (personal digital assistant, PDA), smart car, smart television, robot, etc.

It should be noted that, in some possible implementations, the electronic device may also be referred to as a terminal device, a User Equipment (UE), or the like, which is not limited by the embodiment of the present application.

Referring to fig. 3 and fig. 4, fig. 3 and fig. 4 show schematic diagrams of an application scenario according to an embodiment of the application.

As shown in fig. 3 (a), the electronic device is in a state of being on or being restarted and being locked, the electronic device may register a monitoring fingerprint function, acquire a fingerprint moving effect picture from the memory 1 in advance after registering the monitoring fingerprint function, decode the fingerprint moving effect picture, and store the decoded fingerprint moving effect picture in the memory 2; as shown in fig. 3 (b) -fig. 4 (a), after the user places the finger in the fingerprint recognition area on the display screen, the fingerprint sensor under the display screen may receive a touch operation, and thus, the electronic device may display a moving effect screen according to the fingerprint moving effect pixel data in the memory 2; meanwhile, the electronic device starts to match the fingerprint image acquired by the fingerprint sensor with a pre-stored fingerprint image, as shown in (b) of fig. 4, if the matching is successful, the electronic device is successfully unlocked, and a main interface (interface without screen) of the electronic device is displayed.

After the electronic device is turned off, the step of decoding the fingerprint moving effect picture and storing the decoded fingerprint moving effect picture in the memory 2 is not needed, so that the fingerprint sensor of the electronic device can display the moving effect picture directly according to the fingerprint moving effect pixel data in the memory 2 after receiving the contact operation next time.

For example, the moving effect screen corresponding to (b) in fig. 3- (a) in fig. 4 may be: and the fingerprint identification area is taken as a circle center to be outwards diffused to form an elliptic pattern which is larger than the fingerprint identification area.

It should be understood that the foregoing is illustrative of a scenario and is not intended to limit the scenario of the present application in any way.

The application framework layer 202 may include two sub-layers, a java layer and a native layer, respectively.

Specifically, the fingerprint service (fingerprint service) module, the power management service (power manager service, PMS) module, and the graphics processing (graphics) module belong to the java layer in the application framework layer 202. The pressure quiesce information (pressure stall information, PSI) module and the graphic image processing library belong to the native layer in the application framework layer 202.

The pressure dwell information (pressure stall information, PSI) module is a module for collecting and recording the pressure conditions of the memory 2. The fingerprint service (fingerprint service) module is a module for handling fingerprint recognition functions. The power management service (power manager service, PMS) is a module for managing power and device status.

In the following, the electronic device is taken as an example, and the moving effect picture display method provided by the embodiment of the application is described in detail with reference to the accompanying drawings and application scenes.

Referring to fig. 7, fig. 7 is a flowchart illustrating a moving-effect picture display method according to an embodiment of the application.

As shown in fig. 7, the moving effect picture display method provided by the present application may include:

s21, the fingerprint service module registers a fingerprint monitoring function with the fingerprint identification module.

S22, the fingerprint identification module registers the fingerprint monitoring function with the fingerprint identification trusted application module.

Wherein a fingerprint recognition (fingerprint) module is a software module in a hardware abstraction of the electronic device. The fingerprinting trusted application module is a software module in a secure execution environment system (trusted execution environment, TEE) of the electronic device.

The fingerprint recognition module is a module for performing a fingerprint recognition function. The fingerprint identification trusted application module is a module for monitoring fingerprint information and verifying and matching fingerprint images.

Among these, the secure execution environment system (trusted execution environment, TEE) is a combined system of hardware and software for creating a secure execution environment to protect critical data and sensitive operations. TEE provides a trusted execution environment in which applications may run while preventing malware, attackers, or privileged code from interfering with or damaging them.

If the electronic device has already opened the fingerprint unlocking function, after the electronic device is started or restarted each time, the electronic device is in a state of being on-screen and locked, the fingerprint service module can execute S21 in the state, register the fingerprint monitoring on the fingerprint identification module, and after the fingerprint service module registers the monitoring fingerprint function on the fingerprint identification module, the fingerprint identification module can execute S22, register the monitoring fingerprint function on the fingerprint identification trusted application module.

That is, the fingerprint service module can register fingerprint monitoring on the fingerprint identification trusted application module through the fingerprint identification module, so that the fingerprint identification module has the function of monitoring the fingerprint image.

S23, the fingerprint identification trusted application module sends a monitoring message to the fingerprint identification module.

S24, the fingerprint identification module sends a monitoring message to the fingerprint service module.

The monitoring message is used for indicating that the monitoring fingerprint function is started successfully.

Based on the above, after the fingerprint service module registers the monitoring fingerprint function with the fingerprint identification trusted application module through the fingerprint identification module, the fingerprint identification trusted application module sends a monitoring message to the fingerprint service module through the fingerprint identification module, so that the fingerprint service module can conveniently determine that the starting of the monitoring fingerprint function of the electronic equipment is successful.

S25, the fingerprint service module reads the fingerprint moving effect picture from the memory 1 and decodes the fingerprint moving effect picture to obtain fingerprint moving effect pixel data.

The fingerprint moving effect picture is a picture corresponding to the moving effect picture.

In some embodiments, the fingerprint moving picture is pre-stored in the memory 1 and can be read when required.

In some embodiments, memory 1 is a universal flash memory (universal flash storage, UFS).

In other embodiments, the memory 1 is an embedded multimedia memory card (embedded multi media card, EMMC).

The memory 1 has the characteristics of being not easy to lose, and the like, and when the electronic equipment is restarted or turned off, the data in the memory 1 are not cleared, so that the electronic equipment can be stored for a long time.

It will be appreciated that pictures are typically stored in a compressed format to reduce storage space and facilitate transmission. Therefore, before displaying or processing a picture, it is necessary to decode the picture first, converting the picture from a compressed format to a format that can be used for processing and display, i.e., a readable format.

In some embodiments, the decoding process may include:

decompressing the fingerprint moving effect picture to obtain the pixel data of the fingerprint moving effect picture.

Based on the pixel data, it is stored in a grid or matrix format.

The pixel data is composed of orderly arranged pixel points, and each pixel point is composed of a plurality of color channels, such as R, G, B three color channels.

Wherein the set of pixel data includes pixel data of a fingerprint moving effect picture corresponding to the set of pixel data.

For example, when the number of pictures in the fingerprint moving effect picture is 24, the number of pixel data in the decoded fingerprint moving effect pixel data is 24 groups.

Based on the above, after the fingerprint monitoring function is successfully registered, the fingerprint service module reads the fingerprint moving effect picture from the memory 1 and decodes the fingerprint moving effect picture, so that fingerprint moving effect pixel data corresponding to the fingerprint moving effect picture can be obtained, and data preparation is performed for the subsequent fingerprint service module to display the moving effect picture according to the fingerprint moving effect pixel data.

S26, the fingerprint service module stores the decoded fingerprint dynamic effect pixel data into the memory 2.

Based on S25, the fingerprint service module may obtain the fingerprint moving effect pixel data, and thus, the fingerprint service module may store the fingerprint moving effect pixel data in the memory 2.

The fingerprint moving effect pixel data comprises a plurality of groups of pixel data, one group of pixel data corresponds to one fingerprint moving effect picture, and one group of pixel data comprises pixel data of one fingerprint moving effect picture corresponding to the one group of pixel data.

In some embodiments, the memory 2 is a random-access memory (RAM).

The memory 2 has the characteristics of being volatile, and the like, and when the electronic device is restarted or turned off, the data in the memory 2 is cleared.

And S27, when the contact operation is received, the fingerprint sensor sends an identification message to the fingerprint identification module.

S28, the fingerprint identification module sends an identification message to the fingerprint service module.

The fingerprint sensor may be disposed in the electronic device in various manners.

In some embodiments, the fingerprint sensor is located below and electrically connected to a display screen of the electronic device.

The fingerprint sensor is used for collecting fingerprint images; when the fingerprint sensor is positioned below the display screen of the electronic device, the fingerprint sensor can receive a contact operation when a user contacts the corresponding position of the display screen, which is connected with the fingerprint sensor, so that the fingerprint sensor starts to collect fingerprint images of the user.

The fingerprint sensor may be an optical fingerprint sensor, a capacitive fingerprint sensor, an ultrasonic fingerprint sensor or an inductive fingerprint sensor.

The application is not limited to the type of fingerprint sensor.

Wherein the identification information is used for indicating the start of fingerprint identification. The identification message may be an interrupt event.

When the fingerprint sensor is positioned below the display screen of the electronic device, a user can not only collect fingerprint images but also receive contact operation when touching the corresponding position of the display screen, which is electrically connected with the display screen, of the fingerprint sensor, so that the fingerprint sensor sends identification information to the fingerprint identification module according to the contact operation, and the fingerprint identification module sends the identification information to the fingerprint service (fingerprint service) module after receiving the fingerprint identification information.

Thus, the fingerprint service module can start to display the dynamic effect picture after receiving the identification message.

S29, the fingerprint service module reads fingerprint dynamic effect pixel data from the memory 2.

Based on S26, the fingerprint service module has already stored the fingerprint moving effect pixel data in the memory 2, so the fingerprint service module needs to read the fingerprint moving effect pixel data from the memory 2, so as to prepare data for the fingerprint service module to display the moving effect picture on the display screen of the electronic device according to the fingerprint moving effect pixel data.

S30, the fingerprint service module displays the dynamic effect picture according to the fingerprint dynamic effect pixel data.

Based on S29, after receiving the identification message, the fingerprint service module may read the fingerprint moving effect pixel data from the memory 2, so that a moving effect screen can be displayed according to the fingerprint moving effect pixel data.

For example, after the fingerprint service module reads the fingerprint moving effect pixel data, each group of pixel data in the fingerprint moving effect pixel data can be respectively drawn on the canvas to obtain a plurality of pictures corresponding to the fingerprint moving effect picture, and then the drawn plurality of pictures are sequentially displayed to form the effect of dynamic display image.

Optionally, after receiving the identification message, the fingerprint service module may further determine whether fingerprint moving effect pixel data exists in the memory 2, so that, when the fingerprint service module reads the fingerprint moving effect pixel data from the memory 2, and displays a moving effect picture according to the fingerprint moving effect pixel data; when the fingerprint service module does not exist, the fingerprint service module reads the fingerprint moving effect picture from the memory 1, decodes the fingerprint moving effect picture, stores the decoded fingerprint moving effect pixel data into the memory 2, reads the fingerprint moving effect pixel data from the memory 2, and displays the moving effect picture according to the fingerprint moving effect pixel data.

S31, the fingerprint sensor sends the fingerprint image to the fingerprint identification trusted application module.

After the fingerprint image is collected, the fingerprint sensor can send the fingerprint image to the fingerprint identification trusted application module, so that the fingerprint identification trusted application module can conveniently verify and match the fingerprint according to the fingerprint image after receiving the fingerprint image.

S32, the fingerprint identification trusted application module verifies and matches the fingerprint image.

After the fingerprint image is collected, the fingerprint sensor sends the fingerprint image to the fingerprint identification trusted application module, so that the fingerprint identification trusted application module can perform fingerprint verification and matching according to the fingerprint image after receiving the fingerprint image.

In some embodiments, fingerprint authentication and matching by the fingerprint identification trusted application module from the fingerprint image comprises the steps of:

and step 1, extracting fingerprint characteristics according to the fingerprint image acquired by the fingerprint sensor.

And 2, comparing the extracted fingerprint features with the fingerprint features of the pre-stored fingerprint images to obtain a similarity value.

And 3, judging whether the fingerprint features corresponding to the collected fingerprint images are matched with the stored fingerprint features of the fingerprint images according to the similarity values.

Step 4, if the matching is successful, the unlocking is successful, and the user can access the functions and data of the electronic equipment by using the electronic equipment; if the matching fails, the electronic device can refuse to unlock and remind the user to try to unlock again, or remind the user to unlock by adopting other unlocking modes, such as passwords or patterns.

The application does not limit the fingerprint verification and matching process.

S33, the fingerprint identification trusted application module sends a fingerprint identification result to the fingerprint identification module.

S34, the fingerprint identification module sends a fingerprint identification result to the fingerprint service module.

Based on S32, the fingerprint identification trusted application module performs fingerprint verification and matching according to the fingerprint image, and after the fingerprint verification and matching are finished, the fingerprint identification result is sent to the fingerprint service module.

If the similarity between the fingerprint features of the fingerprint image acquired by the fingerprint sensor and the fingerprint features of the pre-stored fingerprint image is greater than or equal to a similarity threshold, the fingerprint identification result sent by the fingerprint identification trusted application module to the fingerprint service module is used for indicating that the fingerprint identification is successful.

If the similarity between the fingerprint features of the fingerprint image acquired by the fingerprint sensor and the fingerprint features of the pre-stored fingerprint image is smaller than a similarity threshold, the fingerprint identification result sent by the fingerprint identification trusted application module to the fingerprint service module is used for indicating that the fingerprint identification fails.

And S35, when the received fingerprint identification result shows that the fingerprint identification is successful, the fingerprint service module closes the function of monitoring the fingerprint.

When the received fingerprint identification result shows that the fingerprint identification is successful, the fingerprint service module closes the function of monitoring the fingerprint, so that the power consumption of the electronic equipment can be reduced, and the electric quantity of the electronic equipment can be saved.

Optionally, S35 may include:

after the moving effect picture is displayed and the fingerprint identification is successful, the fingerprint service module can compress the fingerprint moving effect pixel data in the memory 2.

Therefore, the pressure of the memory 2 of the electronic equipment can be released, the performance of the electronic equipment can be prevented from being reduced, the running programs are prevented from being crashed, and the performance and the stability of the electronic equipment system are ensured.

In some embodiments, the fingerprint service module may perform object-level compression on the fingerprint motion pixel data in the memory 2, and in this step, the fingerprint service module needs to perform object-level decompression (object-level compression) on the fingerprint motion pixel data in the memory 2.

Wherein object level decompression is to decompress each compressed object independently, rather than decompressing the entire file; for example, each set of pixel data is decompressed independently.

The object-level decompression technique requires each object to be stored separately, provides a more flexible access method, simultaneously avoids unnecessary performance consumption of the electronic device caused by decompression of the whole file, and can improve efficiency and flexibility.

In some embodiments, the process of object-level compression of the fingerprint active pixel data in memory 2 by the fingerprint service module may include:

1. and determining a virtual address corresponding to the physical address stored in the memory 2 and the size of the storage space occupied by the fingerprint dynamic effect pixel data.

2. And compressing the fingerprint effective pixel data according to the virtual address and the size of the storage space occupied by the fingerprint effective pixel data through a recovery (reclaim) node of the system process.

It should be appreciated that the virtual address corresponds to the actual storage location of a physical page (physical address) in memory 2.

The application framework layer comprises a java layer and a native layer. The java layer includes a graphics processing (graphics) module. The native layer includes a graphic image processing library (libhwui).

In some embodiments, in conjunction with fig. 8, the fingerprint service module compresses the fingerprint active pixel data in the memory 2, which may specifically include:

The fingerprint service module can call a graphics processing (graphics) module of the java layer, so that the graphics processing module calls a graphics image processing library of the active layer based on a recovery (reclaim) interface (system function), then the graphics image processing library calls a proc/pid/reclaim interface, and the proc/pid/reclaim interface calls a fs/proc interface of a kernel (kernel) layer, and compression of fingerprint dynamic pixel data in the memory 2 is realized by adopting the memory management module.

The RECLAIM interface can call proc/pid/RECLAIM interface to compress fingerprint dynamic pixel data in the memory 2 by recovering the reclaim_range function provided by the RECLAIM interface.

Based on the above, the fingerprint service module compresses the fingerprint effective pixel data stored in the memory 2, so that the pressure of the memory 2 can be reduced; further, if the fingerprint service module performs object-level compression on the fingerprint motion effect pixel data stored in the memory 2, the pressure of the memory 2 can be reduced to a greater extent.

According to the moving effect picture display method, when the electronic equipment is started or restarted and is in a bright screen locking state, the fingerprint service module can register a monitoring fingerprint function, then the fingerprint service module acquires fingerprint moving effect pictures from the memory 1, after decoding, the decoded fingerprint moving effect pixel data are stored in the memory 2, and the fingerprint moving effect pixel data are read from the memory 2, so that when the fingerprint service module receives an identification message, the moving effect picture can be displayed according to the fingerprint moving effect pixel data in the memory 2, after the display is finished, the fingerprint moving effect pixel data in the memory 2 are not deleted, and therefore, when the fingerprint service module receives the identification message next time, the fingerprint service module determines that the fingerprint moving effect pixel data exist in the memory 2, and the electronic equipment can display the moving effect picture directly according to the fingerprint moving effect pixel data in the memory 2, so that the decoding time is saved, the power consumption of the electronic equipment is reduced, and the electric quantity consumption of the electronic equipment is reduced.

In a possible implementation manner, the electronic device is taken as an example, and the moving effect picture display method provided by the embodiment of the application is described in detail with reference to the accompanying drawings.

Referring to fig. 9, fig. 9 is a flowchart illustrating a moving-effect picture display method according to an embodiment of the application.

As shown in fig. 9, the moving effect picture display method provided by the present application may include:

s41, the fingerprint service module registers a monitoring screen-off event with the power management service module.

The fingerprint service (fingerprint service) module and the pressure power management service (power manager service, PMS) module are software modules in an application framework layer (FWK) of the electronic device.

The fingerprint service module is used for processing fingerprint identification functions; the power management service module is a module for managing power and electronic device status.

The fingerprint service module registers a monitoring screen-off event on the power management service module, so that the power management service module has a function of sending a screen-off message when monitoring that the electronic equipment is off screen.

The manner in which the fingerprint service module registers the monitor off-screen event on the power management service module may include: the fingerprint service module registers the off-screen broadcast on the power management service module, or the fingerprint service module registers the off-screen event callback function on the power management service module.

In the process of starting or restarting the electronic equipment each time, the fingerprint service module needs to execute S51, and a monitoring screen-off event is registered on the power management service module, so that the power management service module can inform the fingerprint service module when monitoring that the display screen of the electronic equipment is off, and the fingerprint service module can execute corresponding operation.

Specifically, after the fingerprint service module registers a monitoring screen-off event on the power management service module, if the electronic equipment is in screen-off state, the power management service module can send a screen-off message to the fingerprint service module, and after the fingerprint service module receives the screen-off message, the fingerprint service module can execute corresponding operation.

Therefore, the fingerprint service module registers monitoring screen-off events on the power management service module, so that the fingerprint service module can acquire the screen-off events of the electronic equipment in time, and the fingerprint service module can conveniently perform corresponding operations according to the screen-off events.

Wherein S41 is an optional step.

S42, when the display screen of the electronic equipment is turned off, the power management service module sends an off-screen message to the fingerprint service module.

The screen-off message is used for indicating that the display screen of the electronic equipment is off.

In some embodiments, when the electronic device is started or restarted, the fingerprint service module registers a monitor screen-off event on the power management service module, and when the power management service module monitors that the display screen of the electronic device is off, the power management service module can send a screen-off message to the fingerprint service module to inform the fingerprint service module that the electronic device is off.

In other embodiments, the electronic device includes an off-screen application, and the off-screen application is capable of sending an off-screen message to the fingerprint service module to notify the fingerprint service module that the electronic device has been off-screen when the electronic device is off-screen.

The first screen-off of the electronic device may occur before the fingerprint sensor receives the contact operation performed by the user on the electronic device, and the fingerprint sensor sends the identification message to the fingerprint service module through the fingerprint identification module, or may occur after the fingerprint sensor receives the contact operation performed by the user on the electronic device, and the moving effect picture is displayed.

If the display of the moving effect picture is finished and the fingerprint identification is successful, the fingerprint service module compresses the fingerprint moving effect pixel data in the memory 2, and then the fingerprint service module can directly decompress the fingerprint moving effect pixel data after receiving the screen-off message.

Optionally, S42 may further include:

s43, the fingerprint service module judges whether the function of monitoring the fingerprint is registered.

If the electronic equipment opens the fingerprint unlocking function and the electronic equipment screen-off occurs after the moving effect picture is displayed, the electronic equipment already executes the steps S21-S24 and the steps S25-S35; since the fingerprint service module has turned off the listening fingerprint function in S35, then the fingerprint service module determines that the listening fingerprint function is not registered at this time.

If the electronic equipment does not open the fingerprint unlocking function and the electronic equipment screen-off occurs after the dynamic effect picture is displayed, the electronic equipment does not execute the steps S21-S35; then the fingerprint service module determines that the listening fingerprint function is unregistered at this point. If the electronic equipment opens the fingerprint unlocking function and the electronic equipment screen-off occurs before the contact operation is received, the electronic equipment executes the steps S21-S24; then the fingerprint service module determines that the listening fingerprint function is registered at this point.

If the electronic equipment does not open the fingerprint unlocking function and the electronic equipment screen-off occurs before the contact operation is received, the electronic equipment does not execute the steps S21-S24; then the fingerprint service module determines that the listening fingerprint function is unregistered at this point.

Therefore, the fingerprint service module needs to determine whether the function of monitoring the fingerprint is registered.

When the monitoring fingerprint function is registered, the fingerprint service module executes S48; when the monitor fingerprint function is not registered, the fingerprint service module performs S48 after S44-S47.

S44, the fingerprint service module registers the fingerprint monitoring function with the fingerprint identification module.

S45, the fingerprint identification module registers the fingerprint monitoring function with the fingerprint identification trusted application module.

S46, the fingerprint identification trusted application module sends a monitoring message to the fingerprint identification module.

S47, the fingerprint identification module sends a monitoring message to the fingerprint service module.

The implementation of S44-S47 is similar to the implementation of S21-S24 in the embodiment shown in fig. 7, and will not be described here again.

S48, the fingerprint service module judges whether fingerprint dynamic effect pixel data exist in the memory 2.

If the electronic equipment does not open the fingerprint unlocking function, after the electronic equipment is started or restarted, the electronic equipment does not execute the steps S21-S35; then the fingerprint service module determines that no fingerprint active pixel data is present in the memory 2.

If the electronic equipment opens the fingerprint unlocking function, after the electronic equipment is started or restarted, the electronic equipment executes the steps S21-S35; then the fingerprint service module determines that fingerprint active pixel data is present in the memory 2.

Therefore, the fingerprint service module needs to determine whether the fingerprint active pixel data exists in the memory 2.

When the fingerprint dynamic effect pixel data does not exist in the memory 2, the fingerprint service module executes S49-S51; when the fingerprint dynamic pixel data exists in the memory 2, the fingerprint service module performs S51.

And S49, the fingerprint service module reads the fingerprint moving effect picture from the memory 1 and decodes the fingerprint moving effect picture to obtain fingerprint moving effect pixel data.

S50, the fingerprint service module stores the decoded fingerprint dynamic effect pixel data into the memory 2.

The implementation of S49 and S50 is similar to the implementation of S25 and S26 in the embodiment shown in fig. 7, and will not be described here again.

And S51, when the fingerprint dynamic effect pixel data in the memory 2 is compressed data, the fingerprint service module decompresses the fingerprint dynamic effect pixel data.

The reading of the fingerprint moving effect pixel data from the memory 2 is similar to the implementation of S30 in the embodiment shown in fig. 7, and will not be described herein.

Based on the above description, after the display of the moving-effect picture is finished and the fingerprint identification is successful, the fingerprint service module can compress the fingerprint moving-effect pixel data in the memory 2, so that when the screen-off message is received, if the fingerprint service module determines that the fingerprint moving-effect pixel data is compressed data, the fingerprint moving-effect pixel data needs to be decompressed.

In some embodiments, the fingerprint service module can compress the fingerprint effective pixel data in the memory 2 to a memory page of the memory 2, so that when the display screen of the electronic device is turned off, the fingerprint service module can scan the virtual address and the occupied storage space corresponding to the compression of the fingerprint effective pixel data in the memory 2 through the mlock interface (system function), and trigger the decompression of the fingerprint effective pixel data.

Continuing to combine with fig. 8, the fingerprint service module decompresses the fingerprint dynamic effect pixel data through the mlock interface, which may specifically include: the fingerprint service module can call a graphics processing (graphics) module of the java layer, so that the graphics processing module calls a graphics image processing library of the active layer based on a memory lock (mlock) interface (system function), then the graphics image processing library calls the mlock interface, and then a memory management module of the kernel (kernel) layer is called through the mlock interface to lock a physical page corresponding to fingerprint dynamic pixel data in the memory 2.

In the locking process, the memory management module of the kernel layer scans the physical page and the size of the occupied storage space in the memory 2 corresponding to the virtual address of the fingerprint effective pixel data, scans the vma function corresponding to the physical page in the memory 2 corresponding to the fingerprint effective pixel data, and decompresses the data in the exchange partition onto the physical page if the data mapped by the vma function is found in the exchange partition, thereby actively triggering the decompression of the fingerprint effective pixel data.

Based on the above description, after the electronic device is off-screen, the fingerprint service module decompresses the fingerprint active pixel data through the mlock interface, so that in the off-screen state, the fingerprint active pixel data is always stored in the memory 2 and is in an uncompressed state, and then when the fingerprint service module receives the identification message, the fingerprint service module can directly read the fingerprint active pixel data in the memory 2 without passively triggering to decompress the fingerprint active pixel data from the switch (swap) partition of the memory 2. Meanwhile, as the fingerprint dynamic effect pixel data is locked (lock) in the memory 2 through the lock interface, the fingerprint dynamic effect pixel data can be prevented from being compressed again by the fingerprint service module after the screen is turned off.

In some embodiments, the fingerprint service module is capable of unlocking the locked fingerprint active pixel data via the munlock interface after each active screen display is completed.

Referring to fig. 8, the fingerprint service module unlocks the locked fingerprint active pixel data through the munlock interface, which may specifically include:

the fingerprint service module can call a graphics processing (graphics) module of a java layer, so that the graphics processing module calls a graphics image processing library of a native layer based on a memory lock (Munlock) interface (system function), then the graphics image processing library calls the Munlock interface, and then a memory management module of a kernel (kernel) layer is called through the Munlock interface to realize unlocking of a physical page corresponding to the locked fingerprint effective pixel data, and after unlocking, compression of the fingerprint effective pixel data can be triggered again when the pressure level of the memory 2 is high.

If the fingerprint service module executes S41, S21 to S35 are executed after S41. If the off-screen event of the electronic device occurs after S35, S42-S51 are performed after S35.

For example, the electronic device is started or restarted at 10 point 48 minutes 0 seconds, S41 is executed, a monitor off event is registered, S21-S24 is executed at 10 point 48 minutes 15 seconds, a monitor fingerprint function is registered, if the user performs fingerprint unlocking at 10 point 48 minutes 30 seconds, the fingerprint service module executes S27-S34, and when the fingerprint identification result in S34 indicates that the fingerprint identification is successful, S35 is executed, and the monitor fingerprint function is closed; after a period of time, at point 10 and 52 minutes and 55 seconds, the electronic equipment is turned off, S42 is executed, after receiving the off-screen message, the fingerprint service module executes S43, if the unregistered monitoring fingerprint function is determined, S44-S47 is executed, S48 is executed, if yes, S51 is executed, and if no, S49-S51 is executed; if it is determined that the monitor fingerprint function is registered, S48 is executed, if yes, S51 is executed, and if no, S49-S51 are executed.

According to the moving effect picture display method, before the screen is turned off, the electronic equipment possibly registers a monitoring fingerprint function, fingerprint moving effect pixel data obtained by decoding the fingerprint moving effect picture in the memory 1 is stored in the memory 2, namely the electronic equipment registers the monitoring fingerprint function; it is also possible to turn off the monitor fingerprint function so that the monitor fingerprint function is not registered; the snoop fingerprint function may not have been registered; then, when the electronic device is off-screen, the off-screen function may be registered, or the off-screen function may not be registered, and the fingerprint active pixel data may not exist in the memory 2, or may exist in the memory; therefore, when the monitor fingerprint function is not registered and the fingerprint moving effect pixel data does not exist in the memory 2, the monitor fingerprint function is registered, and the fingerprint moving effect pixel data obtained by decoding the fingerprint moving effect picture in the memory 1 is stored in the memory 2, so that the moving effect picture is ready for data to be displayed when the contact operation is received next time.

In addition, when the pressure level of the memory 2 is greater than the threshold 1, the fingerprint service module needs to compress the fingerprint dynamic effect pixel data, so that the fingerprint dynamic effect pixel data needs to be decompressed; when the electronic equipment is off-screen, the fingerprint dynamic effect pixel data is decompressed, compared with when the electronic equipment is on-screen, the fingerprint dynamic effect pixel data is decompressed, so that the power consumption of the electronic equipment can be reduced, and the power consumption of the electronic equipment can be reduced.

Referring to fig. 10, fig. 10 is a flowchart illustrating a moving-effect picture display method according to an embodiment of the application.

As shown in fig. 10, the moving effect picture display method provided by the present application may include:

s61, the fingerprint service module registers a memory monitoring callback function with the pressure pause information module.

If the fingerprint service module executes both S41 and S61, the execution order of S41 and S61 is not sequential, and may be sequentially executed or may be executed simultaneously.

The pressure pause information (pressure stall information, PSI) module is a software module in an application framework layer (FWK) of the electronic device.

The pressure dwell information module is a module for collecting and recording pressure conditions of the memory 2.

Specifically, the pressure pause information module provides a method for evaluating the pressure of the memory (memory) 2, quantifies the interruption of task execution caused by insufficient memory resources of the memory 2, counts the time for waiting for memory allocation of tasks in the system, and is used for measuring the pressure condition of the memory 2. The longer the task waits for the pause time caused by memory allocation, the greater the pressure of the memory 2; the shorter the pause time caused by the task waiting for memory allocation, the less pressure the memory 2 will be. The PSI module opens an interface to the fingerprint service module through the file system node. For example, the fingerprint service module writes "name 1500001000000" to the/proc/pressure/memory node, and may register a memory name event with a statistical time period of 1s and a pressure threshold of 150 ms.

The memory monitor callback function is a specific function, and is used for monitoring and processing the pressure condition of the memory 2.

After the fingerprint service module registers the memory monitoring callback function with the pressure pause information module, the pressure pause information module can reflect the pressure state of the memory 2 through two indexes of a name and full.

The name index is used to represent the percentage of time that one or more tasks have been stalled during a period of time due to waiting for memory allocation of the memory 2. The full indicator is used to indicate the percentage of time that all tasks in the non-idle state have been stalled by waiting for memory allocation of memory 2.

For example, in fig. 11, task a is running without a pause in 60 seconds nearest to the current time, while task B spends 30 seconds waiting for memory allocation during running due to the memory shortage of memory 2, the value of the name is 50 seconds, or 50%, and the value of full is 0.

For another example, in fig. 12, within 60 seconds nearest to the current time, the task B waits for the memory allocation time to be 30 seconds, the task a waits for the memory allocation time to be 10 seconds, and the waiting times of the task a and the task B overlap due to the memory shortage of the memory 2. During this overlapping period of 10 seconds, task a and task B are both waiting for memory allocation, the value of the name is 50 seconds, or 50%, the value of full is 10 seconds, or 10/60=16.66%.

For another example, in fig. 13, in 60 seconds nearest to the current time, the tasks a and B are running for 40 seconds in total, the name event time is 40 seconds in total, the overlapping time period is a full event, and the total time period is 15 seconds, the value of the name is 40 seconds, or 40/60=66.66%, and the value of the full is 15 seconds, or 15/60=25%.

In some embodiments, the pressure dwell information module monitors the pressure condition of the memory 2 by a pressure threshold, wherein the pressure condition of the memory 2 can be monitored by writing a pressure threshold to a/proc/pressure/memory node in the following format:

<some|full><stall amount in us><time window in us>。

and in a preset time period, when the value of the name and/or the full value is greater than the corresponding pressure threshold value, the pressure pause information module can report the pressure level of the memory 2 to the fingerprint service module according to the pressure level corresponding to the name and/or the full value.

The pressure level of the memory 2 is used to indicate the magnitude of the storage pressure of the memory 2, and the higher the pressure level, the greater the pressure of the memory 2, and the lower the pressure level, the lower the pressure of the memory 2.

For example, the preset time period may be 500ms-10s.

For example, in a time period of 1000ms, when the pressure pause information module counts that the value of the name of the memory 2 is greater than the pressure threshold value of 70ms (7%), reporting a Low memory pressure waterline, that is, reporting a pressure level of 1; when the value of the name is greater than the pressure threshold value by 100ms (10%), reporting the Medium memory pressure waterline, namely reporting the pressure grade as grade 2; and when the full value is greater than the pressure threshold value of 70ms (7%), reporting the Critical memory pressure waterline, namely reporting the pressure grade to be equal to grade 3.

Based on this, in each start-up or restarting process of the electronic device, the fingerprint service module needs to execute S21, registers the memory monitoring callback function on the pressure pause information module, that is, the fingerprint service module registers the address of the memory monitoring callback function into the memory monitoring mechanism of the pressure pause information module, so as to prepare for the pressure pause information module to monitor the pressure condition of the memory 2 through the pressure pause information kernel module.

And S62, when the value of the name and/or the full value is greater than the corresponding pressure threshold value, the pressure pause information kernel module sends pressure information to the pressure pause information module.

The kernel module of the pressure pause information (pressure stall information, PSI) is a software module in the kernel layer of the electronic device. The pressure quiescing information kernel module is associated with a pressure quiescing information module, which is capable of monitoring the pressure condition of the memory 2 through the pressure quiescing information kernel module.

Wherein the pressure information comprises the pressure level of the memory 2.

Since the pressure of the memory 2 may vary, it is necessary to monitor the pressure level of the memory 2, so that when the pressure level of the memory 2 is high, the data stored in the memory 2 is processed accordingly.

That is, when the value of the name and/or the full value is greater than the corresponding pressure threshold, the pressure quiescing information kernel module sends pressure information to the pressure quiescing information module to inform the pressure quiescing information module of the pressure condition of the memory 2 at the current time.

Based on the above description, if after the electronic device is started or restarted each time, the fingerprint service module registers the memory monitoring callback function on the pressure pause information module, and the pressure pause information module can monitor the pressure level of the memory 2 through the pressure pause information kernel module, and each time the value of the name and/or the full value is greater than the corresponding pressure threshold value, the pressure pause information kernel module sends pressure information to the pressure pause information module, so that the pressure pause information module can report the pressure information to the fingerprint service module.

And S63, the pressure pause information module sends pressure information to the fingerprint service module.

Based on S62, the pressure pause information module can receive the pressure information sent by the pressure pause information kernel module, so that the pressure pause information module continues to send the pressure information to the fingerprint service module, that is, reports the pressure condition of the memory 2, and can prepare data for the fingerprint service module to judge whether the pressure level of the memory 2 is greater than the threshold 1 according to the pressure information.

The pressure pause information module needs to send pressure information to the fingerprint service module after receiving the pressure information each time.

Based on the description of S61, since the fingerprint service module registers the memory monitoring callback function on the pressure pause information module after the electronic device is started or restarted each time, when the value of the name and/or the full value is greater than the corresponding pressure threshold, S62 is executed, the pressure pause information module is notified according to the pressure level of the memory 2, and S23 is executed by the pressure pause information module, so that the fingerprint service module can execute the corresponding operation.

Optionally, S35 may further include:

s64, the fingerprint service module judges whether the pressure level of the memory 2 is greater than a threshold value 1.

The pressure level of the memory 2 in the electronic device may be varied by a number of factors such that the pressure level of the memory 2 is greater than the threshold 1.

When the pressure level of the memory 2 is greater than the threshold 1, the performance of the electronic device is reduced, and the application program running on the electronic device is crashed or abnormally exited, so that the electronic device needs to reduce the pressure of the memory 2 and improve the performance and stability of the system of the electronic device, for example, compress the data in the memory 2, and the fingerprint service module executes S40.

When the pressure level of the memory 2 is less than or equal to the threshold 1, the performance of the electronic device is in a normal state, and thus the fingerprint service module does not perform any operation, i.e. does not perform compression of the fingerprint active pixel data.

The threshold 1 is preset, and the threshold 1 may be used to avoid the condition that the pressure level of the memory 2 is too high, so that when the pressure level of the memory 2 is high, the fingerprint service module compresses the fingerprint effective pixel data in the memory 2 to reduce the pressure of the memory 2.

For example, the pressure level in the pressure information received by the fingerprint service module is level 1 (Low memory pressure watermark), and the threshold 1 is level 2 (Medium memory pressure watermark), and then the pressure level is less than the threshold 1.

For another example, the fingerprint service module receives the pressure information with a pressure level of 3 (Critical memory pressure pipeline) and a threshold value of 1 (Medium memory pressure pipeline), and then the pressure level is greater than the threshold value of 1.

For another example, the fingerprint service module receives the pressure information with a pressure level of 2 (Medium memory pressure pipeline) and a threshold value of 1 with a pressure level of 2 (Medium memory pressure pipeline), and then the pressure level is equal to the threshold value of 1.

It will be appreciated that the fingerprint service module may receive the pressure information before or after receiving the fingerprint identification result.

The fingerprint service module receives pressure information before receiving the fingerprint identification result can be divided into two cases:

in the case 1, before the fingerprint service module does not receive the identification message sent by the fingerprint sensor, the fingerprint service module receives the pressure information sent by the pressure pause information module; i.e. S62-S63 are performed before S27 is performed.

In the case 2, the fingerprint service module receives the pressure information sent by the pressure pause information module in the processes of receiving the identification information sent by the fingerprint sensor, starting to display the dynamic effect picture and displaying the dynamic effect picture; i.e., in the process of executing S27-S30, S62-S63 are executed.

In some embodiments, if the fingerprint service module receives the pressure information before receiving the fingerprint identification result, the fingerprint service module can determine whether the pressure level of the memory 2 is greater than the threshold 1 according to the pressure information received last time before receiving the fingerprint identification result when the fingerprint service module receives the fingerprint identification result and the fingerprint identification result is used for indicating that the fingerprint identification is successful.

Thus, when the fingerprint service module determines that the pressure level of the memory 2 is greater than the threshold 1 according to the pressure information, the fingerprint service module performs S65, otherwise, does not perform any operation.

For example, the electronic device is started or restarted at 10 point 48 minutes 0 seconds, S61 is executed, the memory monitor callback function is registered, S21-S24 is executed at 10 point 48 minutes 15 seconds, the monitor fingerprint function is registered, the pressure level of the memory 2 changes at 10 point 48 minutes 30 seconds, and the fingerprint identification module executes S62-S63, so that the fingerprint identification module receives the pressure information; if the user performs fingerprint unlocking at 10 points 48 minutes 50 seconds, the fingerprint service module performs S27-S34, and if the fingerprint recognition result in S34 indicates that the fingerprint recognition is successful, the fingerprint recognition module performs S64 according to the pressure information, and if it is determined that the pressure level of the memory 2 is greater than the threshold 1, the fingerprint service module performs S65.

It should be noted that, if the fingerprint service module receives the pressure information before receiving the fingerprint identification result, when the fingerprint service module receives the fingerprint identification result and the fingerprint identification result indicates that the fingerprint identification fails, the fingerprint service module does not perform any operation, that is, does not perform S65.

It will be understood that when the fingerprint recognition result received by the fingerprint service module indicates that fingerprint recognition fails, the user will typically unlock the fingerprint again, if the fingerprint service module executes S65 at this time, when it is determined that the pressure level of the memory 2 is greater than the threshold 1 according to the pressure information received by the fingerprint service module before the fingerprint recognition result is received, the fingerprint effective pixel data is compressed, and then when the user unlocks the fingerprint again, the pixel data in the memory 2 is in a compressed state and is not decompressed, and the effective picture cannot be displayed according to the pixel data in the memory 2.

For example, the electronic device is started or restarted at 10 point 48 minutes 0 seconds, S61 is executed, the memory monitor callback function is registered, S21-S24 is executed at 10 point 48 minutes 15 seconds, the monitor fingerprint function is registered, the pressure level of the memory 2 changes at 10 point 48 minutes 30 seconds, and the fingerprint identification module executes S62-S63, so that the fingerprint identification module can receive the pressure information; if the user performs fingerprint unlocking at 10 points 48 minutes 50 seconds, the fingerprint service module executes S27-S34, and when the fingerprint identification result in S34 indicates that the fingerprint identification fails, the fingerprint service module does not execute S64.

In other embodiments, after the fingerprint recognition result received by the fingerprint service module indicates that the fingerprint recognition is successful, the pressure information is received after a period of time, and the fingerprint service module determines, at the moment of receiving the pressure information, whether the pressure level of the memory 2 is greater than the threshold 1 according to the pressure information.

For example, the electronic device is started or restarted at 10 point 48 minutes 0 seconds, S61 is executed, the memory monitor callback function is registered, S21-S24 is executed at 10 point 48 minutes 15 seconds, the monitor fingerprint function is registered, if the user performs fingerprint unlocking at 10 point 48 minutes 30 seconds, the fingerprint service module executes S27-S34, and when the fingerprint identification result indicates that the fingerprint identification is successful in S34, the user can start to use the electronic device; after a period of time, the pressure level of the memory 2 changes at 10 points 52 for 50 seconds, and the fingerprint recognition module performs S62-S63, so that the fingerprint recognition module can receive the pressure information, and performs S64 according to the pressure information, and if it is determined that the pressure level of the memory 2 is greater than the threshold 1, the fingerprint service module performs S65.

It should be noted that, if the fingerprint service module receives the pressure information after receiving the fingerprint identification result, but when the fingerprint identification result received by the fingerprint service module is used to indicate that the fingerprint identification fails, the fingerprint service module does not perform any operation, that is, does not perform S65.

The fingerprint service module determines that the pressure level of the memory 2 is less than or equal to the threshold 1, and the fingerprint service module does not compress the fingerprint dynamic effect pixel data, so that after the electronic device is off-screen, the fingerprint service module does not execute the decompression step.

It can be understood that the fingerprint recognition result received by the fingerprint service module is used to indicate that fingerprint recognition fails, and in general, the user may perform fingerprint unlocking again, if the fingerprint service module performs S65 to compress the fingerprint moving effect pixel data at this time, then when the user performs fingerprint unlocking again, the pixel data in the memory 2 is in a compressed state, and is not decompressed, and the moving effect picture cannot be displayed according to the pixel data in the memory 2.

S65, the fingerprint service module compresses the fingerprint dynamic effect pixel data in the memory 2.

Based on S64, if the fingerprint service module determines that the pressure level of the memory 2 is greater than the threshold 1, the pressure of the memory 2 is greater, and the fingerprint service module can compress the fingerprint effective pixel data stored in the memory 2, so as to release the pressure of the memory 2.

In some embodiments, the fingerprint service module performs object-level compression (object-level memory compression) on the fingerprint active pixel data in memory 2.

The object level compression is to compress each object to be compressed independently, for example, compress each group of pixel data independently. The object-level compression technology can realize finer-granularity compression control, so that the compression efficiency and performance are improved, the storage space of data on the memory 2 is reduced, and the size of the data in the transmission process is reduced.

Alternatively, S35 may further include:

the fingerprint service module periodically (every preset time period) judges whether the pressure level of the memory 2 is greater than a threshold value 1 according to the pressure information, and compresses the fingerprint dynamic effect pixel data in the memory 2 when the pressure level is greater than the threshold value 1.

According to the dynamic effect picture display method, when the pressure level of the memory 2 is greater than the threshold value 1, the fingerprint service module compresses the fingerprint dynamic effect pixel data, so that the pressure of the memory 2 of the electronic equipment is released, the performance of the electronic equipment is prevented from being reduced, the running program is prevented from being crashed, and the performance and the stability of an electronic equipment system are ensured.

The specific implementation of the pressure level can be seen in fig. 10, which is related to the pressure level and the pressure information.

For a specific implementation of the first threshold, see the relevant description of threshold 1 in fig. 10.

When the fingerprint image is matched with a preset fingerprint image, the fingerprint identification is successful.

And, prior to receiving the first operation, the electronic device may obtain pressure information; in the process of receiving a first operation and displaying a dynamic effect picture on a first interface according to a first pixel data set in a first memory in response to the first operation; the electronic device may obtain pressure information; after the dynamic effect picture is displayed, the electronic equipment can obtain the pressure information.

Thus, after the dynamic effect picture is displayed, whether the pressure level of the first memory is greater than the first threshold value can be determined according to the pressure information.

S410, when a first pixel data set exists in the first memory and the first pixel data set is compressed data, object-level decompression is performed on the first pixel data set.

In S406, since the first pixel data set in the first memory is data subjected to object-level compression, object-level decompression of the first pixel data set is required.

When the first pixel data set is decompressed, the first pixel data set is decompressed through the memory locking interface, and the decompressed first pixel data set is in an incompressible state.

The memory lock interface may be an mlock interface.

In the application, the first pixel data set is locked in the first memory through the memory locking interface, namely the mlock interface locking, so that the first pixel data set is in an incompressible state, and the first pixel data set can be prevented from being compressed again after screen failure.

And after displaying the unlocking moving effect picture on the first interface, the method further comprises the following steps: and converting the first pixel data set into a compressible state through the memory unlocking interface.

The memory unlocking interface may be a munlock interface.

In the application, after unlocking the lock interface through the memory, namely unlocking the mulock interface, the first pixel data set is in a compressible state, and when the pressure level of the first memory is greater than a first threshold value, the compression of the first pixel data set can be triggered again.

The specific implementation of S411 may be referred to the description related to S49 in fig. 9, which is not described herein.

In the application, before the screen is turned off, the function of monitoring the fingerprint may be registered, and the first pixel data set obtained by decoding the first image set in the second memory is stored in the first memory; the monitoring fingerprint function may also be turned off after registering the monitoring fingerprint function and storing a first pixel data set obtained by decoding a first image set in the second memory into the first memory; the snoop fingerprint function may not be registered, and therefore, when the snoop fingerprint function is not registered and the first pixel data set does not exist in the first memory, the snoop fingerprint function is registered, and the first pixel data set obtained by decoding the first image set read in the second memory is stored in the first memory, so that data preparation is made for displaying the active picture when the first operation is received next time.

And because the first pixel data set in the first memory is compressed when the fingerprint identification is successful and the pressure level of the first memory is greater than the first threshold after the display of the dynamic effect picture is finished, the first pixel data set needs to be decompressed, so that the dynamic effect picture is displayed for data preparation when the first operation is received next time; when the electronic equipment is off-screen, the first pixel data set is decompressed, compared with when the electronic equipment is on-screen, the first pixel data set is decompressed, so that the power consumption of the electronic equipment can be reduced, and the power consumption of the electronic equipment can be reduced.
