Description

TECHNICAL FIELD

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

[0002] With the development of the Internet and smart terminals, the interface functions of application programs have become increasingly rich. These interfaces include a variety of elements and components, such as text boxes, images, video players, etc. At the same time, in order to receive user input, there are also various control components, such as buttons and input boxes. The diversity of these components and elements makes the interface of the application program more flexible and colorful.

[0003] In the related art, a mobile device usually adjusts the brightness of the screen due to changes in the intensity of the ambient light. However, due to the precision problem of the ambient light sensor device of the mobile device, the ambient light report value of the ambient light sensor device cannot truly restore the environment in which the user is located, and different users have different preferences for screen brightness, which causes the screen brightness adjusted by the mobile device to be unable to meet the individualized screen brightness needs of the user, thereby affecting the user experience to some extent and possibly causing visual fatigue and reducing the comfort of use. SUMMARY

[0004] In view of the above, it is necessary to provide a screen brightness adjustment method and related equipment, which can individualize the adjustment of screen brightness according to the brightness preference of the user and the average gray scale of the display picture, improve the screen brightness display effect of the electronic device, and thereby improve the user experience.

[0005] In a first aspect, the present application provides a screen brightness adjustment method applied to an electronic device, which can include: in response to a first operation of a user, running an application and displaying an application interface of the application; obtaining a first screen brightness when the electronic device displays the application interface, and an initial brightness value and a first brightness multiplier of the application, the initial brightness value representing the screen brightness value adjusted by the user after entering the application, and the first brightness multiplier being determined according to the average gray scale of the display picture of the application; obtaining the intensity of the ambient light of the electronic device and the actual brightness of the ambient light corresponding to the intensity of the ambient light; calculating a second brightness multiplier according to the initial brightness value, the intensity of the ambient light, the actual brightness of the ambient light, and the first screen brightness, the second brightness multiplier being used to represent the degree of brightness preference of the user under different intensities of the ambient light; calculating a target screen brightness preference value according to the initial brightness value, the first brightness multiplier, and the second brightness multiplier, and adjusting the screen brightness of the electronic device displaying the application interface according to the target brightness value.

[0006] By adopting the technical solutions, the electronic device can determine the favorite brightness of the user under the application, that is, the initial brightness value, when displaying the application interface, and can also determine the first brightness multiplier of the application. By acquiring the ambient light intensity of the electronic device in real time, whether the ambient light intensity where the electronic device is located changes can be perceived, and when the ambient light intensity changes, the second brightness multiplier under the current ambient light intensity is calculated based on the initial brightness value. Since the first brightness multiplier is determined according to the average gray scale of the display screen of the application, and the second brightness multiplier is used to represent the brightness preference degree of the user under different ambient light intensities, the target brightness value calculated by the initial brightness value, the first brightness multiplier and the second brightness multiplier can accurately represent the required brightness of the user under the ambient light intensity, thereby providing a more comfortable application scene experience for the user.

[0007] In a possible implementation, the initial brightness value is acquired in the following manner: in response to a second operation of the user, a second screen brightness when the electronic device displays the application interface is acquired; and the initial brightness value is determined according to a difference between the second screen brightness and the first screen brightness. By adopting the technical solution, the second operation can be a drag operation of the user on the brightness bar, so that the initial brightness value can accurately reflect the screen brightness requirement of the user when using the application.

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

[0009] In a possible implementation, the brightness preference type of the user is determined according to the initial brightness value, including: when the initial brightness value is a positive value, determining that the brightness preference type is positive preference; and when the initial brightness value is a negative value, determining that the brightness preference type is negative preference. By adopting the technical solution, the brightness preference type can be accurately determined, thereby further improving the accuracy of the target brightness value calculated subsequently.

[0010] In a possible implementation, the environment light brightness change type of the environment light is determined according to the change value of the environment light intensity, including: when the change value of the environment light intensity is a positive value, determining that the environment light brightness change type is brightness increase; and when the change value of the environment light intensity is a negative value, determining that the environment light brightness change type is brightness decrease. By using the above technical solution, the environment light brightness change type can be accurately determined, thereby further improving the accuracy of the target brightness value calculated subsequently.

[0011] In a possible implementation, the second brightness ratio is calculated according to the environment light intensity, the actual brightness of the environment light, the first screen brightness and the ratio calculation strategy determined according to the brightness preference type and the environment light brightness change type, including: in the case where the environment light brightness change type is brightness increase, determining a first preset light intensity threshold interval in which the environment light intensity is located, and obtaining a first actual brightness of the environment light corresponding to the first preset light intensity threshold interval; and calculating the second brightness ratio according to the following formula: BrightenRatio = (N1-D) / (N1-A), where BrightenRatio is the second brightness ratio, N1 is the first actual brightness of the environment light, D is the actual brightness of the environment light, and A is the first screen brightness. By using the above technical solution, the greater the first actual brightness of the environment light N1 is, the smaller the value of the second brightness ratio BrightenRatio is, thereby reducing the target brightness value subsequently, so that the screen brightness of the electronic device when displaying the application interface is not too bright, and the comfort of the user is improved.

[0012] In a possible implementation, the second brightness ratio is calculated according to the environment light intensity, the actual brightness of the environment light, the first screen brightness and the ratio calculation strategy determined according to the brightness preference type and the environment light brightness change type, including: in the case where the brightness preference type is negative preference and the environment light brightness change type is brightness decrease, calculating the second brightness ratio according to the following formula: DarkenRatio = (D-4) / (A-4), where DarkenRatio is the second brightness ratio, D is the actual brightness of the environment light, and A is the first screen brightness. By using the above technical solution, since the brightness preference type of the user is negative preference and the environment light brightness change type is brightness decrease, the change of the actual brightness of the environment light conforms to the brightness preference type of the user, so the size of the second brightness ratio DarkenRatio is irrelevant to the first actual brightness of the environment light N1, and the accuracy of the second brightness ratio DarkenRatio is improved.

[0013] In a possible implementation, the ratio calculation strategy of the second brightness ratio is determined according to the brightness preference type and the ambient light brightness change type, and the second brightness ratio is calculated according to the ambient light intensity, the actual ambient light brightness, the first screen brightness and the ratio calculation strategy, including: in the case that the brightness preference type is positive preference and the ambient light brightness change type is brightness reduction, determining the second preset light intensity threshold interval in which the ambient light intensity is located, and obtaining the second ambient light brightness corresponding to the second preset light intensity threshold interval; the second brightness ratio is calculated according to the following formula: BrightenRatio = (D-N2) / (A), wherein BrightenRatio is the second brightness ratio, N2 is the second ambient light brightness, D is the actual ambient light brightness, and A is the first screen brightness. According to the above technical solution, since the brightness preference type of the user is positive preference and the ambient light brightness change type is brightness reduction, and since the user needs brighter screen brightness, a larger second brightness ratio BrightenRatio is set to obtain a larger target brightness value, which can meet the screen brightness requirement of the user.

[0014] In a possible implementation, the determination manner of the first brightness ratio includes: collecting a plurality of target images of the application; calculating a gray level histogram of each target image, and calculating an average gray level histogram of the application according to the gray level histogram of each target image; and calculating the first brightness ratio according to the average gray level histogram. According to the above technical solution, since the average gray level histogram can intuitively reflect the overall brightness distribution of the application, the first brightness ratio calculated based on the average gray level histogram can accurately reflect the brightness requirement of the application itself, thereby improving the accuracy of the target brightness value calculated based on the first brightness ratio, and the screen brightness of the electronic device adjusted according to the target brightness value can better meet the screen brightness requirement of the user, thereby improving the use comfort of the user.

[0015] In a possible implementation, the first brightness ratio is calculated according to the average gray level histogram, including: calculating the average gray level of the application according to the average gray level histogram; determining a gray level interval range in which the average gray level is located, and calculating the corresponding relationship between the gray level in the gray level interval range and the preference ratio according to the preset preference ratio corresponding to the two end point values of the gray level interval range; and calculating the first brightness ratio according to the average gray level and the corresponding relationship. According to the above technical solution, the first brightness ratio can be accurately calculated, thereby further improving the accuracy of the target brightness value calculated based on the first brightness ratio.

[0016] In a possible implementation, the electronic device is installed with a preset application, the preset application comprises a brightness adjustment interface, and the method further comprises: adjusting the screen brightness when the electronic device displays the application interface based on a plurality of controls in the brightness adjustment interface. By using the above technical solution, the brightness adjustment function can be performed in the preset application when the electronic device displays the application interface.

[0017] In a possible implementation, the preset application is connected with the electronic device through an F interface. By using the above technical solution, since the F interface is a third-party interface, the screen brightness of the electronic device when displaying the application interface can be adjusted through the preset application even when the electronic device is in a brightness-locked state, the independence of the electronic device brightness adjustment and the application scene brightness adjustment is realized, and the use experience of the user is further improved.

[0018] In a possible implementation, the target brightness value is calculated according to the initial brightness value, the first brightness multiplier and the second brightness multiplier, comprising: calculating the target brightness value according to the following formula: target brightness value = initial brightness value × (first brightness multiplier × k + second brightness multiplier × (1-k)), wherein k is a weight. By using the above technical solution, by configuring different weights for the first brightness multiplier and the second brightness multiplier, the accuracy of the target brightness value calculated based on the first brightness multiplier and the second brightness multiplier can be further improved, the screen brightness of the electronic device adjusted according to the target brightness value can better meet the screen brightness demand of the user, and the use comfort of the user is improved.

[0019] In a second aspect, the present application provides an electronic device, comprising a display screen, a memory and a processor; a microphone, the display screen and the memory are coupled with the processor; the memory is used for storing program instructions; the processor is used for reading the program instructions stored in the memory to realize the screen brightness adjustment method of the first aspect and possible implementation manners thereof.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains. The terminology used in this application's specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. It should be understood that, unless otherwise stated, " / " in this application means "or". For example, A / B can mean A or B. "And / or" in this application is merely a description of the relationship between related objects, indicating that three relationships can exist.

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

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

[0035] A user interface (UI) is the medium through which an application or operating system interacts and exchanges information with the user. It converts the internal form of information into a form that the user can understand. The user interface is written in specific computer languages ​​such as Java or Extensible Markup Language (XML). This source code is parsed and rendered on the electronic device, ultimately presenting content that the user can recognize. A common form of user interface is the graphical user interface (GUI), which refers to a user interface related to computer operation displayed graphically. It can be visible interface elements displayed on the screen of an electronic device, such as text, icons, buttons, menus, tabs, text boxes, dialog boxes, status bars, navigation bars, and widgets.

[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, cloud desktop applications, etc.

[0037] The F interface is defined as the interface between the Mobile Switching Center (MSC) and the Equipment Identifier Register (EIR). It is used to exchange relevant International Mobile Equipment Identity (IMEI) management information. The physical link of the F interface is implemented through a standard 2.048 Mbits PCM digital transmission link between the MSC and the EIR.

[0038] As shown in Figure 1 A screen display scenario provided by an embodiment of the present application includes an electronic device 100. The electronic device 100 can be a device with a display function, and the device type of the electronic device 100 is not limited in the embodiment of the present application. For example, the electronic device 100 can 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 smart phone for example, a user A uses the electronic device 100, for example, Figure 1 The screen display scenario shown in FIG. 1C is a display interface of the electronic device 100 in a game scenario. The user A controls the screen brightness in the game scenario by clicking the “brightness adjustment” control of the application and then dragging the brightness bar. Since the brightness adjustment function is set to a manual adjustment state at this time, the game brightness does not change with the ambient light, but always maintains the brightness adjusted by the user. This situation leads to that, during the game process of the user A, if the ambient light intensity changes, the electronic device 100 cannot adaptively change the screen brightness in the game scenario according to the ambient light intensity, which affects the user's use comfort. That is Figure 1 The screen display scenario shown in FIG. 1D exists a demand for the electronic device 100 to adaptively adjust the screen brightness based on the change of the ambient light intensity, in order to provide the user with a better game experience.

[0039] In order to improve the display effect of the electronic device, the electronic device generally defaults to turn on the ambient light adjustment algorithm to automatically adjust the screen brightness based on different ambient light intensities. However, there is a lack of personalized adjustment of the screen brightness in different applications, and the screen brightness demand of the user when entering different applications cannot be met.

[0040] Therefore, an embodiment of the present application provides a screen brightness adjustment method, so that the electronic device can dynamically adjust the screen brightness according to the ambient light intensity, the user's brightness preference and the average gray scale of the display screen of the current application, and meet the screen brightness demand of the user when entering different applications.

[0041] Please refer to Figure 2 A scene schematic diagram of a screen brightness adjustment method applicable to an embodiment of the present application. The scene includes an electronic device 100. The electronic device 100 can be a device with a display function, and the device type of the electronic device 100 is not limited in the embodiment of the present application. For example, the electronic device 100 can be a mobile phone, a tablet computer, a personal computer, a VoIP phone, etc.

[0042] Taking a smartphone as an example, the electronic device 100 has a first application installed. The electronic device 100 can respond to the first user's first operation, run the first application and display the application interface of the first application. The first user can adjust the screen brightness of the electronic device 100 when displaying the application interface through a second application.

[0043] Specifically, electronic devices can provide a second application UI for selecting screen brightness adjustment, making it easy for users to 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 automatic adjustment.

[0044] For example, such as Figure 3 As shown, taking a mobile phone as the electronic device and a game manager as the second application, the electronic device responds to the operation of clicking the game manager application icon and displays the main settings interface 101 of the game manager application. The main settings interface 101 may include one or more controls, such as a "brightness adjustment" control, a "do not disturb" control, a "prevent accidental touch" control, a "network acceleration" control, a "frame rate enhancement" control, and a "image quality enhancement" control.

[0045] The electronic device responds to the operation of clicking the "Brightness Adjustment" control in the main settings interface 101, and 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 on... Figure 3 The description box below the "Brightness Adjustment" control is shown. For example, the text "The device automatically adjusts the screen brightness when enabled" can be displayed below the "Brightness Adjustment" control.

[0047] To better understand the implementation details of the above screen brightness adjustment method on electronic devices, the following section will combine... Figure 4 to Figure 5 This section describes the process by which various software and hardware components in an electronic device work together to achieve the screen brightness adjustment method described above. Details are as follows:

[0048] The operating system of an electronic device can adopt a layered architecture, event-driven architecture, microkernel architecture, microservice architecture, or cloud architecture. This application uses the layered architecture Android system as an example to illustrate the software structure of the electronic device. Figure 4As shown, the layered architecture divides software into several layers, each of which has a clear role and division of labor. 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, from top to bottom, the application layer (Apk), the application framework layer (Framework), and the hardware abstraction layer (HAL).

[0049] The application layer can include a series of application packages. For example, the application packages can include a game manager 1.0 version application, a game manager 2.0 version application, a system application, and the like. The game manager 1.0 version application can include a first control that supports screen brightness adjustment. The game manager 2.0 version application can include a second control that supports screen brightness adjustment, and the second control supports adjusting the screen brightness by dragging the brightness bar when the screen brightness adjustment function is in a locked state. The system application can include a settings application.

[0050] The application framework layer provides an application programming interface (API) and a programming framework for the applications of the application layer. For example, the application framework layer can include a display effect module, a brightness module, a decision platform, and an F interface module.

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

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

[0053] The decision platform can be used to be responsible for the version switching of the game manager application, such as switching the game manager 1.0 version application to the game manager 2.0 version application.

[0054] The game manager 1.0 version application is connected with the display effect module, and when the electronic device runs the game manager 1.0 version application, the adjustment of the screen brightness can only be realized by the user dragging the brightness bar.

[0055] The game manager 2.0 version application is connected with 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 version application, such as being responsible for managing the locking and unlocking of the screen brightness adjustment, the maximum screen display brightness setting, and the screen brightness adjustment.

[0056] It is worth mentioning that the game manager 2.0 version application can adjust the screen brightness of the electronic device through the F interface module connected to the power supply of the electronic device, and the game manager 2.0 version application and the brightness module can adjust the screen brightness of the electronic device, and the game manager 2.0 version application and the brightness module are decoupled, that is, the system brightness of the electronic device and the screen brightness of the electronic device when displaying the application interface are independent of each other. When the system brightness of the electronic device is in a locked state, that is, the screen brightness of the electronic device cannot be adjusted by the brightness module, the game manager 2.0 version application can automatically adjust the screen brightness of the electronic device when displaying the application interface, thereby improving the user experience.

[0057] For ease of understanding, the following will specifically describe how to adjust the screen brightness of the electronic device when displaying the application interface when the electronic device runs the game manager 1.0 version application and the game manager 2.0 version application.

[0058] Taking that the electronic device is running a game as an example, when the electronic device runs the game manager 1.0 version application, if the user clicks the "brightness adjustment" control, the screen brightness of the electronic device when displaying the game picture is in a locked state, and the user cannot adjust the screen brightness by dragging the brightness bar, at this time, the game brightness does not change with the ambient light, but always maintains the brightness, and when the game is exited, the electronic device returns to the automatic brightness. When the user clicks the "brightness adjustment" control again, that is, the "brightness adjustment" control is in an inoperative state, the user can adjust the screen brightness by dragging the brightness bar.

[0059] When the electronic device runs the game manager 2.0 version application, if the user clicks the "brightness adjustment" control, the user can still adjust the screen brightness by dragging the brightness bar, and when 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 configured to calculate a second brightness ratio according to the obtained parameters, and send the second brightness ratio to the game manager 2.0 version application. It should be noted that the calculation method of the second brightness ratio is described in detail below, and will not be repeated here.

[0061] In some embodiments, the calculation of the second brightness ratio can also be performed in the game manager 2.0 version application.

[0062] The hardware abstraction layer includes a histogram processing module and the like. The histogram processing module is configured to generate an average gray histogram of each application, and upload the average gray 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 multiplier of each application according to the average gray histogram uploaded by the histogram processing module.

[0064] In some embodiments, the histogram unit uploads the calculated first brightness multiplier to the game manager 2.0 version application, and the game manager 2.0 version application calculates the target brightness value based on the first brightness multiplier, the second brightness multiplier and the initial brightness value pre-stored by itself, 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 further includes a platform switching unit and a capability support unit. The capability support unit is used to detect the version adaptation capability of the game manager application of the electronic device, and the platform switching unit is used to send version switching information to the decision hub according to the detection result of the capability support unit, so as to realize the version switching of the game manager application of the electronic device.

[0065] For example, as shown in Figure 5 When the capability support unit detects that the electronic device adapts to the game manager 1.0 version application, and the current electronic device is the game manager 2.0 version application, the capability support unit sends the detection result that the electronic device adapts to the game manager 1.0 version application to the platform switching unit, the platform switching unit sends the version switching information to the decision hub, and the decision hub switches the game manager 2.0 version application installed in the electronic device to the game manager 1.0 version application after receiving the version switching information. Through the above-mentioned version switching mode of the game manager application, the compatibility of the historical version and the new version of the game manager is realized, so that the version of the game manager application can be flexibly managed, and the reliability of the electronic device when running the game manager application is improved.

[0066] In some embodiments, the automatic upgrade of the game manager application version is realized through the cloud, for example, when the current game manager application version installed in the electronic device is the game manager 1.0 version, the cloud automatically upgrades the game manager 1.0 version to the game manager 2.0 version, and after the game manager application version is upgraded to the game manager 2.0 version, the game manager application sends an upgrade reminder to the electronic device through the F interface, and the game manager 2.0 version application writes the permanent attributes such as "brightness bar" and "brightness adjustment" in the electronic device. It should be noted that, in order to avoid the influence of the related functions of the electronic device, only when the user performs the restart operation of the game manager application, the application version switching is completed, and the electronic device provides a support capability interface for the game manager application to query, so as to realize the stability and interlocking of the functions.

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

[0068] In some embodiments, in order to prevent the user from being confused about the determination of the target brightness value and the intelligent adjustment of the screen brightness, the target brightness value is discounted and cleaned up by setting a game re-entry time interval. At the same time, the game manager application sets to clear the 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 can also have more or less structure, which is not limited in the present application.

[0070] In order to more intuitively understand the process of cooperation between the above-mentioned software modules to realize the screen brightness adjustment of the electronic device, the following will take the interactive diagram shown in Figure 6 As an example to introduce the screen brightness adjustment process of the electronic device when running the game application under different ambient light brightness change types.

[0071] As shown in Figure 6 , it is the interactive process of each software and hardware module when the ambient light brightness change type is brightness increase or brightness decrease.

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

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

[0074] 602: The game manager application obtains the first screen brightness when the electronic device displays the game screen, and the initial brightness value and the first brightness multiplier of the game application.

[0075] In some embodiments, the game manager application is the game manager 2.0 version application shown in Figure 4 . After the game manager 2.0 version application obtains the initial brightness value and the first brightness multiplier, the game manager 2.0 version application stores the initial brightness value and the first brightness multiplier in the local, and when the electronic device runs the application next time, the game manager 2.0 version application directly obtains the initial brightness value and the first brightness multiplier from the local, thereby reducing the load of 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 multiplier is determined according to the average gray scale of the display screen of the application.

[0077] In some embodiments, the initial brightness value is obtained according to the following manner: in response to a second operation of the user, obtaining a second screen brightness when the electronic device displays the application interface; determining the initial brightness value according to the difference between the second screen brightness and the first screen brightness.

[0078] As shown in Figure 2 The game butler 2.0 version application has a "brightness bar" control. Taking the application currently running on the electronic device as the game application A, when the electronic device displays the game screen of the 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 when the electronic device displays the game screen is brightness 1, which is the first screen brightness. The first screen brightness is the default value of the screen brightness when the electronic device runs the game application A. The default value of the screen brightness can be determined by the ambient light intensity of the electronic device, and the embodiment does not make specific limitation on the determination method of the default value of the screen brightness.

[0080] After the user drags the brightness bar, the screen brightness when the electronic device displays the game screen is brightness 2, which is the second screen brightness. Since the second screen brightness is adjusted and set by the user, the second screen brightness can be regarded as the favorite brightness of the user when the electronic device runs the game application A. The difference between brightness 2 and brightness 1 is taken as the initial brightness value, so that the initial brightness value can truly reflect the favorite type of the user for the screen brightness. For example, if the initial brightness value is positive, it indicates that the user prefers brighter screen brightness when the electronic device runs the game application A. If the initial brightness value is negative, it indicates that the user prefers darker screen brightness when the electronic device runs the game application A.

[0081] In some embodiments, the first brightness multiplier is determined according to the average gray scale of the display screen of the application.

[0082] Similarly, taking the application currently running on the electronic device as the game application A, the electronic device collects a plurality of target images of the game application A. For example, when the game application A is running, the electronic device can collect a target image of the game application A every 100 frames, until the electronic device collects 100 target images of the game application A. It can be understood that the embodiment does not make specific limitation on the collection method and the number of target images, which can be set according to actual needs.

[0083] The electronic device calculates the gray scale histogram of each target image, and calculates the average gray scale histogram of the game application A according to the gray scale histogram of each target image.

[0084] In some embodiments, the step of calculating the average gray scale histogram can be performed when Figure 4The first brightness ratio is calculated according to the average gray value of the game application A and the corresponding relationship between the gray value in the gray interval range and the favorite ratio.

[0085] For example, assuming that the average gray value of the game application A is Ax, the gray interval range in which Ax is located is (A1, A2), the preset favorite ratio corresponding to A1 is a1, and the preset favorite ratio corresponding to A2 is a2, then the first brightness ratio corresponding to hist is ax=(a2-a1)(Ax-A1) / (A2-A1)+a1.

[0086] In some embodiments, after the first brightness ratio is obtained by the histogram processing module, the first brightness ratio is sent to the game manager 2.0 version application.

[0087] In some embodiments, if the version of the game application A is iterated, the electronic device reacquires the target image of the game application A, so that the first brightness ratio of the game application A is corrected by the histogram processing module, to further ensure the accuracy of the subsequent target brightness value.

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

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

[0090] In some embodiments, the brightness module determines the brightness favorite type of the user according to the initial brightness value, determines the ambient light brightness change type of the ambient light according to the change value of the ambient light intensity, determines the ratio calculation strategy of the second brightness ratio according to the brightness favorite type and the ambient light brightness change type, and calculates the second brightness ratio according to the ambient light intensity, the ambient light actual brightness, the first screen brightness, and the ratio calculation strategy.

[0091] Specifically, when the initial brightness value is positive, the brightness favorite type is determined to be positive favorite; when the initial brightness value is negative, the brightness favorite type is determined to be negative favorite; 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] In a case where the brightness preference type is positive preference or negative preference, and the ambient light brightness change type is brightness increase, a first preset light intensity threshold interval in which the ambient light intensity is located is determined, and a first ambient light brightness corresponding to the first preset light intensity threshold interval is obtained;

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

[0094] BrightenRatio = (N1-D) / (N1- A), wherein BrightenRatio is the second brightness ratio, N1 is the first ambient light brightness, D is the actual ambient light brightness, and A is the first screen brightness. It can be seen from the above formula that the greater the first ambient light brightness N1 is, the smaller the value of the second brightness ratio BrightenRatio is, thereby reducing the subsequent target brightness value, so that the screen brightness of the electronic device when displaying the application interface is not too bright, and the comfort of the user is improved.

[0095] In a case where the brightness preference type is negative preference, and the ambient light brightness change type is brightness decrease, the second brightness ratio is calculated according to the following formula:

[0096] DarkenRatio = (D-4) / (A-4), wherein DarkenRatio is the second brightness ratio, D is the actual ambient light brightness, and A is the first screen brightness. It can be seen from the above formula that, in a case where the brightness preference type of the user is negative preference, and the ambient light brightness change type is brightness decrease, since the change of the ambient light brightness conforms to the brightness preference type of the user, the size of the second brightness ratio DarkenRatio is irrelevant to the first ambient light brightness N1.

[0097] In a case where the brightness preference type is positive preference, and the ambient light brightness change type is brightness decrease, a second preset light intensity threshold interval in which the ambient light intensity is located is determined, and a second ambient light brightness corresponding to the second preset light intensity threshold interval is obtained;

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

[0099] BrightenRatio = (D-N2) / (A), where BrightenRatio is the second brightness ratio, N2 is the second ambient light brightness, D is the actual brightness of the ambient light, and A is the first screen brightness. As can be seen from the above formula, the smaller the second ambient light brightness N2, the larger the second brightness ratio BrightenRatio, and the larger the target brightness value calculated subsequently. 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 needs a brighter screen brightness, a larger second brightness ratio BrightenRatio is set to obtain a larger target brightness value, which can meet the user's screen brightness requirement.

[0100] 605: The game manager application calculates a target brightness value according to the initial brightness value, the first brightness ratio, and the second brightness ratio.

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

[0102] Target brightness value = initial brightness value x (first brightness ratio x k + second brightness ratio x (1-k)), where k is a 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 picture according to the target brightness value.

[0105] In some embodiments, the game manager 2.0 version application takes the sum of the target brightness value and the first screen brightness as the screen brightness of the electronic device.

[0106] By adopting the technical solution, the electronic device can determine the favorite brightness of the user under the application, that is, the initial brightness value, and also determine the first brightness multiplier of the application when displaying the application interface. By acquiring the ambient light intensity of the electronic device in real time, whether the ambient light intensity where the electronic device is located changes can be perceived, and when the ambient light intensity changes, the second brightness multiplier under the current ambient light intensity is calculated based on the initial brightness value. Since the first brightness multiplier is determined according to the average gray scale of the display screen of the application, and the second brightness multiplier is used to represent the brightness preference degree of the user under different ambient light intensities, the target brightness value calculated by the initial brightness value, the first brightness multiplier and the second brightness multiplier can accurately represent the required brightness of the user under the ambient light intensity, thereby providing the user with a more comfortable application scene experience.

By acquiring the ambient light intensity of the electronic device in real time, whether the ambient light intensity where the electronic device is located changes can be perceived, and when the ambient light intensity changes, the second brightness multiplier under the current ambient light intensity is calculated based on the initial brightness value.
