Description

Technical Field

[0001] The present application relates to the field of terminal equipment and communication technology, and in particular to a screen brightness adjustment method and related equipment. Background Art

[0002] With the development of the internet and smart devices, application interfaces have become increasingly versatile. These interfaces include a variety of elements and components, such as text boxes, images, and video players. Furthermore, various control components, such as buttons and input boxes, are also present to receive user input. This diversity of components and elements makes application interfaces more flexible and colorful.

[0003] In related technologies, mobile devices usually adjust the screen brightness due to changes in ambient light intensity. However, due to the accuracy issues of the ambient light sensor devices of mobile devices, the ambient light report value of the ambient light sensor devices cannot truly restore the user's environmental conditions, and different users have different preferences for screen brightness. As a result, the adjusted screen brightness of the mobile device cannot meet the user's personalized screen brightness requirements, which affects the user experience to a certain extent, may cause visual fatigue, and reduce the comfort of use. Summary of the Invention

[0004] In view of the above, it is necessary to provide a screen brightness adjustment method and related equipment, which can personalize the screen brightness according to the user's brightness preference and the average grayscale of the display image, improve the screen brightness display effect of the electronic device, and thus improve the user experience.

[0005] In the first aspect, the present application provides a screen brightness adjustment method, which is applied to an electronic device. The screen brightness adjustment method may include: in response to a user's first operation, running an application and displaying an application interface of the application; obtaining the first screen brightness when the electronic device displays the application interface, as well as the initial brightness value and the first brightness magnification of the application, the initial brightness value representing the screen brightness value adjusted after the user enters the application, and the first brightness magnification is determined according to the average grayscale of the display screen of the application; obtaining the ambient light intensity of the electronic device and the actual brightness of the ambient light corresponding to the ambient light intensity; calculating the second brightness magnification based on the initial brightness value, the ambient light intensity, the actual brightness of the ambient light and the first screen brightness, the second brightness magnification being used to represent the user's brightness preference under different ambient light intensities; calculating the target screen brightness preference value based on the initial brightness value, the first brightness magnification and the second brightness magnification, and adjusting the screen brightness of the electronic device displaying the application interface according to the target brightness value.

[0006] By adopting the above technical solution, the electronic device can determine the user's preferred brightness under the application when displaying the application interface, that is, the initial brightness value, and can also determine the first brightness magnification of the application. By obtaining the ambient light intensity of the electronic device in real time, it can sense whether the ambient light intensity of the electronic device has changed, and when the ambient light intensity changes, calculate the second brightness magnification under the current ambient light intensity based on the initial brightness value. Since the first brightness magnification is determined according to the average grayscale of the display screen of the application, the second brightness magnification is used to characterize the user's brightness preference under different ambient light intensities. Therefore, the target brightness value calculated by the initial brightness value, the first brightness magnification and the second brightness magnification can accurately measure the user's required brightness under the ambient light intensity, thereby providing the user with a more comfortable application scenario experience.

[0007] In one possible implementation, obtaining the initial brightness value includes: obtaining a second screen brightness of the electronic device when displaying the application interface in response to a second user operation; and determining the initial brightness value based on the difference between the second screen brightness and the first screen brightness. Using this technical solution, the second operation can be a user dragging the brightness bar, so that the initial brightness value accurately reflects the user's desired screen brightness when using the application.

[0008] In one possible implementation, the second brightness magnification is calculated based on the initial brightness value, the ambient light intensity, the actual ambient light brightness, and the first screen brightness, including: determining the user's brightness preference type based on the initial brightness value; determining the ambient light brightness change type of the ambient light based on the change value of the ambient light intensity; determining a magnification calculation strategy for the second brightness magnification based on the brightness preference type and the ambient light brightness change type, and calculating the second brightness magnification based on the ambient light intensity, the actual ambient light brightness, the first screen brightness, and the magnification calculation strategy. By adopting the above technical solution, the magnification calculation strategy is determined based on different brightness preference types and different ambient light brightness change types, so that the calculated second brightness magnification can comprehensively consider the user's screen brightness requirements and the current ambient light intensity changes, thereby further improving the accuracy of the target brightness value calculated based on the second brightness magnification, so that the screen brightness of the electronic device adjusted according to the target brightness value can better meet the user's screen brightness requirements, thereby improving the user's comfort.

[0009] In one possible implementation, determining the user's brightness preference type based on the initial brightness value includes determining the brightness preference type as positive when the initial brightness value is positive, and determining the brightness preference type as negative when the initial brightness value is negative. This technical solution accurately determines the brightness preference type, thereby further improving the accuracy of the subsequently calculated target brightness value.

[0010] In one possible implementation, the type of ambient light brightness change is determined based on the ambient light intensity change value, including: determining the ambient light brightness change type as a brightness increase when the ambient light intensity change value is positive; and determining the ambient light brightness change type as a brightness decrease when the ambient light intensity change value is negative. Using this technical solution, the ambient light brightness change type can be accurately determined, thereby further improving the accuracy of the subsequently calculated target brightness value.

[0011] In one possible implementation, a second brightness magnification ratio calculation strategy is determined based on the brightness preference type and the ambient light brightness change type, and the second brightness magnification ratio is calculated based on the ambient light intensity, the actual ambient light brightness, the first screen brightness, and the ratio calculation strategy. The calculation includes: when the ambient light brightness change type is brightness increase, determining the first preset light intensity threshold interval in which the ambient light intensity is located, and obtaining the first ambient light brightness corresponding to the first preset light intensity threshold interval; and calculating the second brightness magnification ratio according to the following formula: BrightenRatio = (ND) / (NA), where BrightenRatio is the second brightness magnification ratio, N is the first ambient light brightness, D is the actual ambient light brightness, and A is the first screen brightness. Using the above technical solution, when the first ambient light brightness N is larger, the value of the second brightness magnification ratio BrightenRatio is smaller, thereby reducing the subsequent target brightness value, so that the screen brightness of the electronic device when displaying the application interface will not be too bright, thereby improving user comfort.

[0012] In one possible implementation, a ratio calculation strategy for the second brightness ratio is determined based on the brightness preference type and the ambient light brightness change type, and the second brightness ratio is calculated based on the ambient light intensity, the actual ambient light brightness, the first screen brightness, and the ratio calculation strategy, including: when the brightness preference type is a negative preference and the ambient light brightness change type is brightness reduction, the second brightness ratio is calculated according to the following formula: DarkenRatio = (D-4) / (A-4), where DarkenRatio is the second brightness ratio, D is the actual ambient light brightness, and A is the first screen brightness. With the above technical solution, since the user's brightness preference type is a negative preference and the ambient light brightness change type is brightness reduction, and since the change in ambient light brightness conforms to the user's brightness preference type, the size of the second brightness ratio DarkenRatio is set to be independent of the first ambient light brightness N, thereby improving the accuracy of the second brightness ratio DarkenRatio.

[0013] In one possible implementation, a second brightness magnification ratio calculation strategy is determined based on the brightness preference type and the ambient light brightness change type, and the second brightness magnification ratio is calculated based on the ambient light intensity, the actual ambient light brightness, the first screen brightness, and the ratio calculation strategy. The strategy includes: when the brightness preference type is positive and the ambient light brightness change type is brightness reduction, determining the second preset light intensity threshold interval within which the ambient light intensity falls, and obtaining the second ambient light brightness corresponding to the second preset light intensity threshold interval; and calculating the second brightness magnification ratio based on the following formula: BrightenRatio = (DN) / (A), where BrightenRatio is the second brightness magnification ratio, N is the second ambient light brightness, D is the actual ambient light brightness, and A is the first screen brightness. Using the above technical solution, since the user's brightness preference type is positive and the ambient light brightness change type is brightness reduction, and since the user requires a brighter screen brightness, a larger second brightness magnification ratio BrightenRatio is set to obtain a larger target brightness value, thereby meeting the user's screen brightness requirement.

[0014] In one possible implementation, the method for determining the first brightness magnification includes: collecting multiple target images of the application; calculating the grayscale histogram of each target image, and calculating the average grayscale histogram of the application based on the grayscale histogram of each target image; and calculating the first brightness magnification based on the average grayscale histogram. With the above technical solution, since the average grayscale histogram can intuitively reflect the overall brightness distribution of the application, the first brightness magnification calculated based on the average grayscale histogram can accurately reflect the brightness requirements of the application itself, thereby improving the accuracy of the target brightness value calculated based on the first brightness magnification, so that the screen brightness of the electronic device adjusted according to the target brightness value can better meet the user's screen brightness requirements, thereby improving the user's comfort.

[0015] In one possible implementation, calculating the first brightness magnification based on the average grayscale histogram includes: calculating the average grayscale of the application based on the average grayscale histogram; determining the grayscale interval within which the average grayscale falls, and calculating a correspondence between the grayscales within the grayscale interval and the preferred magnifications based on the preset preferred magnifications corresponding to the two endpoints of the grayscale interval; and calculating the first brightness magnification based on the average grayscale and the correspondence. Using this technical solution, the first brightness magnification can be accurately calculated, thereby further improving the accuracy of the target brightness value calculated based on the first brightness magnification.

[0016] In one possible implementation, an electronic device is installed with a preset application, which includes a brightness adjustment interface. The method further includes adjusting the screen brightness of the electronic device when the application interface is displayed based on multiple controls in the brightness adjustment interface. Using the above technical solution, the brightness adjustment function can be performed within the preset application when the electronic device displays the application interface.

[0017] In one possible implementation, the preset application is connected to the electronic device via the F interface. With this technical solution, since the F interface is a third-party interface, even when the electronic device is in a brightness-locked state, the preset application can be used to adjust the screen brightness of the electronic device when displaying the application interface. This achieves the mutual independence of electronic device brightness adjustment and application scenario brightness adjustment, further improving the user experience.

[0018] In one possible implementation, calculating a target brightness value based on an initial brightness value, a first brightness magnification, and a second brightness magnification includes calculating the target brightness value according to the following formula: target brightness value = initial brightness value * (first brightness magnification * k * second brightness magnification * (1-k)), where k is a weight. By employing the above technical solution and assigning different weights to the first brightness magnification and the second brightness magnification, the accuracy of the target brightness value calculated based on the first brightness magnification and the second brightness magnification can be further improved, so that the screen brightness of the electronic device adjusted according to the target brightness value can better meet the user's screen brightness requirements, thereby improving the user's comfort.

[0019] In a second aspect, the present application provides an electronic device, which includes a display screen, a memory, and a processor; the microphone, the display screen, and the memory are all coupled to the processor; the memory is used to store program instructions; and the processor is used to read the program instructions stored in the memory to implement the screen brightness adjustment method of the above-mentioned first aspect and its possible implementation methods.

[0020] In a third aspect, the present application provides a computer-readable storage medium, which stores computer-readable instructions. When the computer-readable instructions are executed by a processor, the screen brightness adjustment method of the above-mentioned first aspect and its possible implementation methods is implemented.

[0021] In a fourth aspect, the present application provides a computer program product, which includes computer-readable instructions. When the computer-readable instructions are executed by a processor, the screen brightness adjustment method of the above-mentioned first aspect and its possible implementation methods is implemented.

[0022] In addition, the technical effects brought about by the second to fourth aspects can be found in the descriptions of the methods of each design in the above method section, and will not be repeated here. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the order of the steps shown in the flowcharts herein can be changed, and some can be omitted.

[0034] To facilitate understanding of the various embodiments of this application, first, the technical terms involved in this application are introduced:

[0035] User interface (UI): It is the media interface for interaction and information exchange between applications or operating systems and users. It realizes the conversion between the internal form of information and the form acceptable to users. The user interface is source code written in a specific computer language such as Java and extensible markup language (XML). The interface source code is parsed and rendered on the electronic device, and ultimately presented as content that the user can recognize. The most common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operations that is displayed graphically. It can be visual interface elements such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, widgets, etc. displayed on the display screen of an electronic device.

[0036] Application (APP): A software program that can perform one or more specific functions. Examples include calling applications, instant messaging applications, video applications, audio applications, image capture applications, and cloud desktop applications.

[0037] The F interface is defined as the interface between the mobile switching center (MSC) and the Equipment Identity Register (EIR). It is used to exchange international mobile equipment identity management information. The physical link of the F interface is a standard 2.048 Mbits PCM digital transmission link between the mobile switching center (MSC) and the Equipment Identity Register (EIR).

[0038] like Figure 1 As shown, a screen display scenario provided in an embodiment of the present application includes an electronic device 100. The electronic device 100 may be a device with a display function, and the embodiment of the present application does not limit the device type of the electronic device 100. For example, the electronic device 100 may be a mobile phone, a tablet computer, a personal computer, a Voice over Internet Protocol (VoIP) phone, etc. Figure 1 Taking the electronic device 100 as a smartphone as an example, user A uses the electronic device 100, for example, Figure 1 The screen display scene shown is the display interface of the electronic device 100 in the game scene. User A clicks the "brightness adjustment" control of the application and then drags the brightness bar to control the screen brightness in the game scene. Since the brightness adjustment function is set to manual adjustment at this time, the game brightness will not change with the ambient light and will always maintain the brightness adjusted by the user. This situation causes the electronic device 100 to be unable to adaptively change the screen brightness in the game scene according to the ambient light intensity when user A is playing the game, affecting the user's comfort. Figure 1 In the screen display scenario shown, in order to provide users with a better gaming experience, there is a need to adaptively adjust the screen brightness of the electronic device 100 based on changes in ambient light intensity.

[0039] In order to improve the display effect of electronic devices, electronic devices generally turn on the ambient light adjustment algorithm by default to automatically adjust the screen brightness based on different ambient light intensities. However, there is a lack of personalized adjustment of the screen brightness for different applications, and it cannot meet the screen brightness requirements of users when entering different applications.

[0040] In view of this, an embodiment of the present application provides a screen brightness adjustment method, which enables the electronic device to dynamically adjust the screen brightness according to the ambient light intensity, user brightness preference and the average grayscale of the display screen of the current application, to meet the user's screen brightness requirements when entering different applications.

[0041] See also Figure 2 , which is a schematic diagram of a scenario for a screen brightness adjustment method applicable to an embodiment of the present application. The scenario includes an electronic device 100. The electronic device 100 may be a device with a display function, and the present embodiment of the present application does not limit the device type of the electronic device 100. For example, the electronic device 100 may be a mobile phone, a tablet computer, a personal computer, a VoIP phone, etc.

[0042] For example, the electronic device 100 is a smartphone, and a first application is installed on the electronic device 100. In response to a first operation by a first user, the electronic device 100 may run the first application and display the application interface of the first application. The first user may adjust the screen brightness of the electronic device 100 when displaying the application interface through a second application.

[0043] Specifically, the electronic device can provide a second application UI for selecting screen brightness adjustment, so that the user can switch the screen brightness adjustment mode of the electronic device, such as setting the screen brightness adjustment mode of the electronic device to manual adjustment, or setting the screen brightness adjustment mode of the electronic device to automatic adjustment.

[0044] For example, Figure 3 As shown, taking the electronic device as a mobile phone and the second application as a game manager as an example, the electronic device displays the setting main interface 101 of the game manager application in response to the operation of clicking the game manager application icon. The setting main interface 101 may include one or more controls, such as a "brightness adjustment" control, a "message do not disturb" control, an "anti-mistouch" control, a "network acceleration" control, a "frame rate enhancement" control, a "image quality enhancement" control, etc.

[0045] In response to the operation of clicking the “brightness adjustment” control in the setting main interface 101 , the electronic device sets the screen brightness adjustment mode of the electronic device to manual adjustment or automatic adjustment.

[0046] In some embodiments, a text description of the corresponding function may be displayed below the "brightness adjustment" control to help users understand the function of the control. For example, the text description may be displayed below the Figure 3 The mode description box below the "Brightness Adjustment" control is shown. For example, the text description "The device automatically adjusts the screen brightness after turning it on" can be displayed below the "Brightness Adjustment" control.

[0047] In order to more clearly understand the implementation details of the above screen brightness adjustment method on the electronic device, Figures 4 and 5 Let's introduce the process of implementing the above screen brightness adjustment method by cooperating with various software and hardware components in electronic devices. The details are as follows:

[0048] The operating system of the electronic device can adopt a layered architecture, event-driven architecture, micro-kernel architecture, micro-service architecture, or cloud architecture. The embodiment of the present application takes the Android system of layered architecture as an example to illustrate the software structure of the electronic device. Figure 4As shown, a layered architecture divides software into several layers, each with distinct roles and responsibilities. Layers communicate with each other through software interfaces. Taking the Android system as an example, in some embodiments, the Android system is divided into three layers: the application layer (APK), the application framework layer (Framework), and the hardware abstraction layer (HAL), from top to bottom.

[0049] The application layer may include a series of application packages. For example, an application package may include applications such as the Game Manager version 1.0 application, the Game Manager version 2.0 application, and system applications. The Game Manager version 1.0 application may include a first control that supports screen brightness adjustment. The Game Manager version 2.0 application may include a second control that supports screen brightness adjustment. The second control supports adjusting the screen brightness by dragging the brightness bar even when the screen brightness adjustment function is locked. System applications may include a settings application.

[0050] The application framework layer provides an application programming interface (API) and programming framework for the applications in the application layer. For example, the application framework layer may include a display effect module, a brightness module, a decision-making center, and an F interface module.

[0051] The display effect module can be used to be responsible for the version adaptability of the electronic device to the game manager application, such as detecting that the game manager application adapted to electronic device 1 is the game manager version 1.0 application, and detecting that the game manager application adapted to electronic device 2 is the game manager version 2.0 application.

[0052] The brightness module can be used to manage the screen display brightness of the electronic device, for example, it is responsible for managing the locking and unlocking of the screen brightness adjustment, setting the maximum display brightness of the screen, and adjusting the screen brightness.

[0053] The decision-making middle platform can be used to be responsible for version switching of the Game Manager application, such as switching the Game Manager version 1.0 application to the Game Manager version 2.0 application.

[0054] The Game Manager version 1.0 application is connected to the display effect module. When the electronic device runs the Game Manager version 1.0 application, the screen brightness can only be adjusted by the user dragging the brightness bar.

[0055] The Game Manager 2.0 application is connected to the power supply of the electronic device through the F interface module, so that the screen display brightness of the electronic device can be directly managed through the Game Manager 2.0 application. For example, it is responsible for managing the locking and unlocking of the screen brightness adjustment, setting the maximum display brightness of the screen, and adjusting the screen brightness.

[0056] It's worth noting that after the Game Manager 2.0 app is connected to the electronic device's power supply via the F-port module, both the Game Manager 2.0 app and the brightness module can adjust the screen brightness of the electronic device. Furthermore, the Game Manager 2.0 app and the brightness module are decoupled from each other, meaning that the electronic device's system brightness and the screen brightness when the electronic device displays the app interface are independent of each other. When the electronic device's system brightness is locked, meaning the brightness of the electronic device's screen cannot be adjusted via the brightness module, the Game Manager 2.0 app can automatically adjust the screen brightness when the electronic device displays the app interface, improving the user experience.

[0057] For ease of understanding, the following specifically describes how to adjust the screen brightness of an electronic device when displaying an application interface when the electronic device runs the Game Manager version 1.0 application and the Game Manager version 2.0 application in this embodiment:

[0058] For example, when an electronic device is running a game, if the user clicks the "Brightness Adjustment" control while the electronic device is running the Game Manager version 1.0 app, the screen brightness of the electronic device will be locked when the game is displayed. The user cannot adjust the screen brightness by dragging the brightness bar. At this time, the game brightness will not change with the ambient light and will remain at that brightness. After exiting the game, the electronic device will return to automatic brightness. If the user clicks the "Brightness Adjustment" control again, that is, the "Brightness Adjustment" control is inactive, the user can adjust the screen brightness by dragging the brightness bar.

[0059] When an electronic device is running the Game Manager 2.0 application, if the user clicks the "Brightness Adjustment" control, the user can still adjust the screen brightness by dragging the brightness bar. Even if the user does not adjust the screen brightness by dragging the brightness bar, the game brightness will be automatically adjusted based on the aforementioned screen brightness adjustment method.

[0060] In some embodiments, the brightness module is used to calculate a second brightness magnification based on the acquired parameters and send the second brightness magnification to the Game Manager 2.0 application. It should be noted that the calculation method of the second brightness magnification is described in detail below and will not be repeated here to avoid repetition.

[0061] In some embodiments, the calculation of the second brightness magnification can also be performed in the Game Manager version 2.0 application.

[0062] The hardware abstraction layer includes a histogram processing module, etc. The histogram processing module is used to generate an average grayscale histogram for each application and upload the average grayscale histogram to the display effect module.

[0063] In some embodiments, the display effect module includes a histogram unit, which can be used to calculate the first brightness magnification of each application according to the average grayscale histogram uploaded by the histogram processing module.

[0064] In some embodiments, the histogram unit uploads the calculated first brightness magnification to the Game Manager 2.0 application. The Game Manager 2.0 application calculates the target brightness value based on the first brightness magnification, the second brightness magnification, and its own pre-stored initial brightness value, and then adjusts the screen brightness of the electronic device display application interface according to the target brightness value. In some embodiments, the display effect module also includes a platform switching unit and a capability support unit. The capability support unit is used to detect the electronic device's version adaptation capability for the Game Manager application, and the platform switching unit is used to send version switching information to the decision-making center based on the detection result of the capability support unit to implement version switching of the electronic device's Game Manager application.

[0065] For example, Figure 5 As shown, when the capability support unit detects that the electronic device is adapted to the Game Manager version 1.0 application, but the current electronic device is using the Game Manager version 2.0 application, the capability support unit sends the detection result of the electronic device adapting to the Game Manager version 1.0 application to the platform switching unit. The platform switching unit sends version switching information to the decision-making center. After receiving the version switching information, the decision-making center switches the Game Manager version 2.0 application installed on the electronic device to the Game Manager version 1.0 application. Through the above-mentioned version switching method of the Game Manager application, compatibility between the historical version and the new version of the Game Manager application is achieved, thereby enabling flexible management of the Game Manager application version and improving the reliability of the electronic device when running the Game Manager application.

[0066] In some embodiments, automatic upgrades of the Game Manager application version are implemented via the cloud. For example, if the electronic device currently has version 1.0 of the Game Manager application installed, the cloud automatically upgrades version 1.0 to version 2.0. After the Game Manager application is upgraded to version 2.0, the Game Manager application sends an upgrade reminder to the electronic device via the F interface. The Game Manager application also writes permanent properties of the electronic device, such as "brightness bar" and "brightness adjustment." It is worth noting that to avoid impacting related functions of the electronic device, the application version switch is only completed when the user restarts the Game Manager application. The electronic device provides a support capability interface for the Game Manager application to query, ensuring functional stability and interlocking.

[0067] In some embodiments, in order to prevent the abnormal crash of the game manager application and cause abnormal brightness adjustment function, when the user turns off the screen, the game manager application function is exited and restored through the game whitelist recognition capability.

[0068] In some embodiments, to prevent users from being confused about the target brightness value and the intelligent adjustment of screen brightness, the target brightness value is discounted and cleared by setting a game re-entry time interval. At the same time, the game manager application sets a clearing channel.

[0069] It can be understood that the above software structure is only exemplary and does not constitute a limitation on the software structure of the electronic device. In other embodiments, the electronic device may have more or fewer structures, and this application does not impose any limitation on this.

[0070] In order to more intuitively understand the process of implementing screen brightness adjustment of electronic devices by cooperating among the above software modules, Figure 6 The interactive diagram shown is used as an example to introduce the process of adjusting the screen brightness of an electronic device when running a game application under different types of ambient light brightness changes.

[0071] like Figure 6 FIG. 1 shows the interaction process of the software and hardware modules when the ambient light brightness change type is brightness increase or brightness decrease.

[0072] 601: The histogram processing module calculates a first brightness magnification of the game application.

[0073] In some embodiments, the electronic device runs the game application and displays the game screen of the game application in response to a user clicking operation on the game application, and the histogram processing module calculates the first brightness magnification of the game application.

[0074] 602: The game manager application obtains the first screen brightness of the electronic device when displaying the game screen, as well as the initial brightness value and the first brightness magnification of the game application.

[0075] In some embodiments, the game manager application is Figure 4 After obtaining the initial brightness value and the first brightness magnification, the Game Manager 2.0 application stores the initial brightness value and the first brightness magnification locally. The next time the electronic device runs the application, the Game Manager 2.0 application directly obtains the initial brightness value and the first brightness magnification locally, thereby reducing the load on the electronic device.

[0076] Specifically, the initial brightness value represents the screen brightness value manually adjusted by the user when entering the application, and the first brightness magnification is determined according to the average grayscale of the display screen of the application.

[0077] In some embodiments, the initial brightness value is obtained in the following manner: in response to the user's second operation, the second screen brightness of the electronic device when the application interface is displayed is obtained; and the initial brightness value is determined based on the difference between the second screen brightness and the first screen brightness.

[0078] like Figure 2 As shown, the Game Manager 2.0 version application has a "brightness bar" control. Taking the application currently running on the electronic device as game application A as an example, when the electronic device displays the game screen of game application A, the user adjusts the screen brightness by dragging the brightness bar. The operation of dragging the brightness bar is the second operation.

[0079] For example, before the user drags the brightness bar, the screen brightness of the electronic device when displaying the game screen is brightness ①, and brightness ① is the first screen brightness. The first screen brightness is the default screen brightness value of the electronic device when running game application A. The default screen brightness value can be determined by the current ambient light intensity of the electronic device. This embodiment does not specifically limit the method for determining the default screen brightness value.

[0080] After the user drags the brightness bar, the screen brightness of the electronic device when displaying the game screen is brightness ②, which is the second screen brightness. Since the second screen brightness is adjusted and set by the user, it can be regarded as the user's preferred brightness when the electronic device is running game application A. The difference between brightness ② and brightness ① is used as the initial brightness value, so that the initial brightness value can truly reflect the user's preference for screen brightness. For example, a positive initial brightness value indicates that the user prefers a brighter screen brightness when the electronic device is running game application A; a negative initial brightness value indicates that the user prefers a darker screen brightness when the electronic device is running game application A.

[0081] In some embodiments, the first brightness magnification is determined according to an average grayscale of a display screen of the application.

[0082] Again, let's assume that the electronic device is currently running game application A. The electronic device collects multiple target images of game application A. For example, while game application A is running, the electronic device may collect a target image of game application A every 100 frames until the electronic device has collected 100 target images of game application A. It should be understood that this embodiment does not impose specific restrictions on the method or number of target image collections, and these can be set based on actual needs.

[0083] The electronic device calculates a grayscale histogram of each target image, and calculates an average grayscale histogram of the game application A based on the grayscale histogram of each target image.

[0084] In some embodiments, the step of calculating the average grayscale histogram may be performed at Figure 4Specifically, after the histogram processing module obtains the average grayscale histogram of game application A, the average grayscale of game application A is calculated based on the average grayscale histogram; the grayscale interval in which the average grayscale falls is determined, and based on the preset preference magnifications corresponding to the two endpoints of the grayscale interval, the corresponding relationship between the grayscale in the grayscale interval and the preference magnification is calculated; and the first brightness magnification is calculated based on the average grayscale and the corresponding relationship.

[0085] For example, assuming that the average grayscale of game application A is Ax, and the grayscale range of Ax is (A1, A2), where the preset preference magnification corresponding to A1 is a1, and the preset preference magnification corresponding to A2 is a2, then the first brightness magnification corresponding to hist is ax = (a2-a1)(Ax-A1) / (A2-A1)+a1.

[0086] In some embodiments, after the histogram processing module obtains the first brightness magnification, the first brightness magnification is sent to the Game Manager version 2.0 application.

[0087] In some embodiments, if the version of game application A undergoes version iteration, the electronic device will reacquire the target image of game application A so that the histogram processing module can correct the first brightness multiplier of game application A to further ensure the accuracy of the target brightness value obtained subsequently.

[0088] 603: The ambient light sensor obtains the ambient light intensity of the electronic device and the actual brightness of the ambient light corresponding to the ambient light intensity.

[0089] 604: The brightness module calculates a second brightness magnification according to the initial brightness value, the ambient light intensity, the actual ambient light brightness, and the first screen brightness.

[0090] In some embodiments, the brightness module determines the user's brightness preference type based on the initial brightness value; determines the ambient light brightness change type of the ambient light based on the change value of the ambient light intensity; determines the magnification calculation strategy of the second brightness magnification based on the brightness preference type and the ambient light brightness change type, and calculates the second brightness magnification based on the ambient light intensity, the actual brightness of the ambient light, the first screen brightness and the magnification calculation strategy.

[0091] Specifically, when the initial brightness value is positive, the brightness preference type is determined to be positive preference; when the initial brightness value is negative, the brightness preference type is determined to be negative preference; the ambient light brightness change type of the ambient light is determined according to the change value of the ambient light intensity, including: when the change value of the ambient light intensity is positive, the ambient light brightness change type is determined to be brightness increase; when the change value of the ambient light intensity is negative, the ambient light brightness change type is determined to be brightness decrease.

[0092] When the brightness preference type is positive preference or negative preference, and the ambient light brightness change type is brightness increase, determining a first preset light intensity threshold interval in which the ambient light intensity is located, and obtaining a first ambient light brightness corresponding to the first preset light intensity threshold interval;

[0093] The second brightness magnification is calculated according to the following formula:

[0094] BrightenRatio = (ND) / (NA), where BrightenRatio is the second brightness ratio, N is the first ambient light brightness, D is the actual ambient light brightness, and A is the first screen brightness. As can be seen from the above formula, when the first ambient light brightness N is greater, the value of the second brightness ratio BrightenRatio is smaller, thereby lowering the subsequent target brightness value, so that the screen brightness of the electronic device displaying the application interface will not be too bright, thereby improving user comfort.

[0095] When the brightness preference type is negative preference and the ambient light brightness change type is brightness reduction, the second brightness magnification is calculated according to the following formula:

[0096] DarkenRatio = (D-4) / (A-4), where DarkenRatio is the second brightness ratio, D is the actual ambient light brightness, and A is the first screen brightness. As can be seen from the above formula, if the user's brightness preference type is negative and the ambient light brightness change type is brightness reduction, the second brightness ratio DarkenRatio is independent of the first ambient light brightness N because the ambient light brightness change meets the user's brightness preference type.

[0097] When the brightness preference type is positive preference and the ambient light brightness change type is brightness reduction, determining a second preset light intensity threshold interval in which the ambient light intensity is located, and obtaining a second ambient light brightness corresponding to the second preset light intensity threshold interval;

[0098] The second brightness magnification is calculated according to the following formula:

[0099] BrightenRatio = (DN) / (A), where BrightenRatio is the second brightness ratio, N is the second ambient light brightness, D is the actual ambient light brightness, and A is the first screen brightness. As can be seen from the above formula, when the second ambient light brightness N is smaller, the second brightness ratio BrightenRatio is larger, so that the target brightness value calculated subsequently is larger. This is because the user's brightness preference type is positive preference, and the ambient light brightness change type is brightness reduction. Since the user requires a brighter screen brightness, setting a larger second brightness ratio BrightenRatio to obtain a larger target brightness value can meet the user's screen brightness requirements.

[0100] 605: The game manager application calculates a target brightness value based on the initial brightness value, the first brightness magnification, and the second brightness magnification.

[0101] In some embodiments, the target brightness value is calculated according to the following formula:

[0102] Target brightness value=initial brightness value*(first brightness magnification*k*second brightness magnification*(1-k)), where k is the weight.

[0103] In some embodiments, the size of k is not specifically limited and can be set according to actual needs.

[0104] 606: The game manager application adjusts the screen brightness of the electronic device when displaying the game screen according to the target brightness value.

[0105] In some embodiments, the Game Manager 2.0 application uses the sum of the target brightness value and the first screen brightness as the screen brightness of the electronic device.

[0106] By adopting the above technical solution, the electronic device can determine the user's preferred brightness under the application when displaying the application interface, that is, the initial brightness value, and can also determine the first brightness magnification of the application. By obtaining the ambient light intensity of the electronic device in real time, it can sense whether the ambient light intensity of the electronic device has changed, and when the ambient light intensity changes, calculate the second brightness magnification under the current ambient light intensity based on the initial brightness value. Since the first brightness magnification is determined according to the average grayscale of the display screen of the application, the second brightness magnification is used to characterize the user's brightness preference under different ambient light intensities. Therefore, the target brightness value calculated by the initial brightness value, the first brightness magnification and the second brightness magnification can accurately measure the user's required brightness under the ambient light intensity, thereby providing the user with a more comfortable application scenario experience. By adopting the above technical solution, the electronic device can determine the user's preferred brightness under the application when displaying the application interface, that is, the initial brightness value, and can also determine the first brightness magnification of the application. By acquiring the ambient light intensity of the electronic device in real time, it is possible to sense whether the ambient light intensity of the electronic device has changed, and when the ambient light intensity changes, calculate the second brightness magnification under the current ambient light intensity based on the initial brightness value. Since the first brightness magnification is determined according to the average grayscale of the display screen of the application, the second brightness magnification is used to characterize the user's brightness preference under different ambient light intensities. Therefore, the target brightness value calculated by the initial brightness value, the first brightness magnification and the second brightness magnification can accurately meet the user's required brightness under the ambient light intensity, thereby providing the user with a more comfortable application scenario experience.

In phone call mode, the processed audio (voice) data may be converted into a format that can be transmitted to a mobile communication base station via the RF unit 101.
