The method in the embodiment can be used for automatically controlling the display parameters of the electronic equipment so as to reduce the brightness adjustment complexity of a user.

Specifically, the method in this embodiment may include the following steps:

step 101: a first environmental parameter at a first time instant is obtained.

The first time may be a current time or a future time at which brightness adjustment of the electronic device is required, such as the current time or a time after 1 second.

It should be noted that the first environmental parameter may include an environmental brightness parameter, and may also include environmental parameters with other attributes, such as temperature or humidity.

Specifically, in this embodiment, a first environmental parameter at a first time may be acquired by using a sensing device such as a light sensor.

Step 102: and obtaining a first adjusting parameter and/or a second adjusting parameter corresponding to the brightness level according to the brightness level corresponding to the first environment parameter.

The brightness level in this embodiment can represent the brightness value in the first environment parameter, for example, the larger the brightness value in the first environment parameter is, the higher the corresponding brightness level is, and the smaller the brightness value in the first environment parameter is, the lower the corresponding brightness level is.

In a specific implementation, the present embodiment may define the ambient light brightness in a predetermined graded manner, for example, the ambient light brightness is divided into 1-100 brightness levels, and each brightness level corresponds to a range of the ambient light brightness. Therefore, in the embodiment, after the first environment parameter is obtained, the brightness level corresponding to the first environment parameter may be determined according to the brightness value in the first environment parameter.

After determining the brightness level corresponding to the first environment parameter, in this embodiment, the first adjustment parameter and/or the second adjustment parameter corresponding to the brightness level corresponding to the first environment parameter may be obtained in a predefined adjustment parameter list corresponding to each brightness level, that is, a preset brightness configuration table.

The adjustment parameter list may include a plurality of brightness levels and one or more adjustment parameters corresponding to each brightness level, where the adjustment parameters include preset adjustment parameters and adjustment parameters generated according to user history operations or user current operations, where the user history operations or user current operations may be understood as brightness adjustment operations performed by a user on the electronic device under environment parameters corresponding to each brightness level.

Correspondingly, in this embodiment, after the brightness level corresponding to the first environment parameter is determined, the adjustment parameter corresponding to the brightness level may be searched in the adjustment parameter list, so as to obtain the first adjustment parameter and/or the second adjustment parameter corresponding to the brightness level, and further, other more adjustment parameters except the first adjustment parameter and/or the second adjustment parameter may also be obtained.

It should be noted that the first adjustment parameter may be an increment parameter that increases or decreases the brightness value of the display parameter of the electronic device, and the second adjustment parameter may be an increment parameter that increases or decreases the brightness value of the display parameter of the electronic device.

Step 103: and adjusting the display parameter of the electronic equipment corresponding to the first environment parameter at least based on the first adjusting parameter and/or the second adjusting parameter.

In this embodiment, the first adjustment parameter and/or the second adjustment parameter may be transmitted to a display unit of the electronic device under the first environmental parameter, or a brightness configuration table may be preset in the electronic device, where the first adjustment parameter and/or the second adjustment parameter are obtained based on the brightness configuration table, and the display unit adjusts the display parameter according to the first adjustment parameter and/or the second adjustment parameter, so that the display parameter of the electronic device corresponds to the first adjustment parameter and/or the second adjustment parameter, thereby achieving a display effect meeting a user requirement without requiring a user to manually adjust the parameter.

Specifically, in this embodiment, the incremental adjustment may be performed according to the first adjustment parameter and/or the second adjustment parameter on the basis of the default display parameter of the electronic device, for example, increasing the brightness corresponding to the adjustment parameter, decreasing the brightness of the adjustment parameter for drinking, increasing the brightness, then decreasing the brightness corresponding to the adjustment parameter, or decreasing the brightness, then increasing the brightness corresponding to the adjustment parameter, and so on.

According to the foregoing scheme, in the brightness adjustment method provided in the embodiment of the present application, after the environmental parameter is obtained, the brightness level representing the brightness value of the environmental parameter corresponding to the environmental parameter is obtained, and the corresponding at least one adjustment parameter is obtained, so as to adjust the display parameter of the electronic device under the environmental parameter according to the adjustment parameters. Therefore, in the embodiment, brightness adjustment of the electronic device on one or more adjustment parameters can be realized by using the brightness level corresponding to the environmental parameter without manually adjusting the brightness by the user, so that the brightness adjustment operation flow of the user is saved, and the operation complexity of the user is reduced.

In one implementation, the step 102 may be implemented by the following steps when obtaining the first adjustment parameter corresponding to the brightness level:

and obtaining a first adjusting parameter based on the position of the first interval where the brightness level is located in a preset brightness configuration table.

In which, as shown in the luminance configuration table in table 1 below, each luminance level has a luminance interval therebetween, a luminance section is formed between adjacent luminance levels, each luminance level corresponds to a luminance section, e.g., luminance level 1 corresponds to luminance section 1, has a default luminance value of 25, luminance level 2 corresponds to luminance section 2, has a default luminance value of 35, and so on. In this embodiment, after determining the brightness level corresponding to the first environment parameter, the position of the first interval where the brightness level is located, for example, the 6 th brightness level, is searched in the brightness configuration table, and accordingly, the first adjustment parameter is obtained according to the position.

For example, the user performs a first operation of increasing the brightness value 5 at the brightness level 1, at this time, the initial brightness value with the brightness level 1 in the brightness configuration table is updated to 25+5, that is, 30, and the first adjustment parameter is recorded as: + 5; further, in this embodiment, the initial brightness values of the brightness intervals corresponding to all adjacent or other brightness levels may also be updated according to the historical operation of the user, for example, a brightness value 5 is added to the initial brightness values of the brightness intervals corresponding to the brightness levels 2 to 7, as shown in table 1, correspondingly, when the electronic device displays, the display parameter of the electronic device is controlled according to the updated brightness value at the brightness level corresponding to the environment parameter, for example, when the brightness level corresponding to the environment parameter is 1, the display brightness in the display parameter of the electronic device is controlled to be 30, when the brightness level corresponding to the environment parameter is 3, the display brightness in the display parameter of the electronic device is controlled to be 45, and so on.

In addition, in this embodiment, when the electronic device performs output display with the adjustment parameter in the updated brightness configuration table, the user may perform brightness adjustment operation again according to the requirement, update the brightness configuration table again, and record the updated increment as the second adjustment parameter.

For example, as shown in the following table 7, in this case, on the basis of the updated brightness value 55 of the brightness interval corresponding to the brightness level 6, the brightness value in the display parameter adjusted by the user is 53, that is, the brightness value is decreased by 2 on the basis of the original brightness value 55, and at this time, in the present embodiment, the brightness value of the brightness interval corresponding to the current brightness level in the brightness configuration table updated by the brightness adjustment operation performed again by the user is adjusted to be consistent with the brightness value adjusted again by the user, and the second adjustment parameter is recorded: -2. In this embodiment, the updated brightness value 55 is updated to 53, that is, 5 is added to the initial brightness value 50 and then 2 is subtracted, and accordingly, when the electronic device performs display, the updated brightness value at the brightness level corresponding to the environment parameter is used to control the display parameter of the electronic device, so that when the brightness level corresponding to the environment parameter is 6, the display brightness in the display parameter of the electronic device is controlled to 53, that is, the brightness value after 5 is added to the initial brightness value 50 and then 2 is subtracted.

Further, in this embodiment, the updated brightness values of the brightness intervals corresponding to all adjacent or other brightness levels may be updated according to the brightness adjustment operation performed again by the user, for example, the updated brightness values of the brightness intervals corresponding to brightness levels 5 and 7 or the updated brightness values of the brightness levels corresponding to all other brightness levels are all decreased by 2, as shown in table 8 below, correspondingly, when the electronic device displays, the display parameter of the electronic device is controlled according to the updated brightness value at the brightness level corresponding to the environmental parameter, for example, when the brightness level corresponding to the environmental parameter is 7, the display brightness in the display parameter of the electronic device is controlled to be increased to 60 on the basis of 55, and then decreased to 58 or increased to 58 on the basis of 55 directly, and so on.

As can be seen, in the present embodiment, the brightness value in the brightness interval corresponding to each brightness level in the brightness configuration table is associated with the brightness value in the adjacent brightness interval, or the brightness value in the brightness interval corresponding to each brightness level is associated with the historical operation performed by the user on the display parameter of the electronic device at the brightness level, or the brightness value in the brightness interval corresponding to each brightness level is associated with both the brightness value in the adjacent brightness interval and the historical operation performed by the user on the display parameter of the electronic device at the brightness level.

In one implementation, when obtaining the first adjustment parameter and/or the second adjustment parameter corresponding to the brightness level in step 102, the following may be implemented:

first, a user identification of a current operator of the electronic device is obtained. The user identifier may be understood as information that uniquely characterizes a user currently using the electronic device, such as a user name, a facial feature identifier, and the like. Specifically, in this embodiment, the user identifier of the current operator of the electronic device may be obtained by reading user information registered in advance in the electronic device, or in this embodiment, the user identifier of the user may be recognized by acquiring a face image or voice data of the user through a camera or a microphone, for example.

And then, according to the user identification and the brightness level corresponding to the first environment parameter, obtaining a first adjusting parameter and/or a second adjusting parameter corresponding to the brightness level.

In this embodiment, different user identifiers have different brightness configuration tables, and brightness levels corresponding to the first environment parameter in the brightness configuration tables corresponding to the corresponding different user identifiers may be different; or, in this embodiment, corresponding brightness levels are set under the same environment parameter for different user identifiers in the brightness configuration table, and corresponding brightness levels corresponding to different user identifiers corresponding to the first environment parameter in the brightness configuration table may be different. For example, user a corresponds to a brightness level of 2 under the first environmental parameter, user B corresponds to a brightness level of 3 under the first environmental parameter, and so on.

Therefore, the brightness levels corresponding to different user identifiers under the first environment parameter are correspondingly set according to the historical operations of different users, and correspondingly, the first adjusting parameter and/or the second adjusting parameter corresponding to the brightness levels corresponding to different user identifiers under the first environment parameter may be different, so in this embodiment, by obtaining the user identifier, and obtaining the brightness level corresponding to the user identifier under the first environment parameter in the brightness configuration table according to the user identifier, or obtaining the brightness level corresponding to the first environment parameter in the brightness configuration table corresponding to the user identifier, the first adjusting parameter and/or the second adjusting parameter corresponding to the brightness level is correspondingly obtained, and then the display parameter of the electronic device corresponding to the first environment parameter is adjusted according to the first adjusting parameter and/or the second adjusting parameter, thereby realizing the personalized brightness adjustment aiming at the user.

In an implementation manner, when the display parameter of the electronic device corresponding to the first environment parameter is adjusted in step 103, the following manner may be specifically implemented:

firstly, obtaining operation parameters of a first display area and/or a second display area of the electronic device, wherein the operation parameters are parameters capable of representing a use state of the display area of the electronic device, for example, parameters for operating one or more display areas of the electronic device through an input device of the electronic device, such as parameters of duration or frequency of mouse cursor clicking or moving, and operation parameters such as key pressing of a keyboard, and the operation parameters are capable of representing states of frequency or duration of operation or use of the electronic device on the corresponding display area.

It should be noted that the electronic device has one or more display areas, such as a display area on the main body display screen and a display area of the projection area, and accordingly, the operation parameter may be for the first display parameter or the second display parameter, or may also be for the first display area and the second display area, for example, the operation parameter is a parameter for the display area on the display screen, or the operation parameter is an operation parameter for the projection area, or the operation parameter includes both the operation parameter of the display area on the display screen and the operation parameter of the projection area on the projection screen, as shown in fig. 2.

Then, based on the operation parameter, the display parameter is adjusted by the first adjusting parameter and/or the second adjusting parameter.

In this embodiment, the display parameters of the corresponding display area may be adjusted by analyzing or determining the parameters representing the use state of the display area in the operation parameters.

Specifically, in this embodiment, when the operation parameter satisfies the first condition, the display parameter may be adjusted by using the first adjustment parameter and/or the second adjustment parameter at the first time, and if the operation parameter satisfies the second condition, the display parameter may not be adjusted or the display parameter may be adjusted so that the adjusted display parameter corresponds to the second condition.

The first condition may be that an operating frequency or a duration of the operating parameter is greater than a certain threshold, and the second condition may be that the operating frequency or the duration of the operating parameter is less than the threshold. When the operation parameter satisfies the second condition, adjusting the display parameter so that the adjusted display parameter corresponds to the second condition may be: and adjusting the brightness in the display parameters to be reduced to a certain value so as to achieve the aim of saving energy when the operating frequency or the duration is lower than a threshold value.

In one implementation, the method in this embodiment may further include the following steps, as shown in fig. 3:

step 104: a second environmental parameter at a second time is obtained.

The second time is different from the first time, and specifically, the second time may be a time after the first time, as shown in fig. 4. In this embodiment, after the display parameter of the electronic device is adjusted according to the first adjustment parameter and/or the second adjustment parameter obtained from the first environment parameter at the first time, the second environment parameter at the second time, such as the environment brightness, is obtained.

Step 105: and obtaining a third adjusting parameter and/or a fourth adjusting parameter corresponding to the second environment parameter according to the brightness level corresponding to the second environment parameter.

In this embodiment, the manner of obtaining the third adjustment parameter and/or the fourth adjustment parameter may refer to the manner of obtaining the first adjustment parameter and/or the second adjustment parameter in the foregoing.

Step 106: and obtaining a parameter adjusting rate based on a grade difference value between the brightness grade corresponding to the first environment parameter and the brightness grade corresponding to the second environment parameter and the third adjusting parameter and/or the fourth adjusting parameter.

The adjustment rate refers to a rate of adjusting the brightness of the display parameter of the electronic device, and may be understood as an adjustment amount of the brightness in a unit time, such as an adjustment rate of 1 brightness in 1 second or 20 brightness values in 1 second.

Specifically, in this embodiment, the corresponding parameter adjustment rate may be obtained by judging the magnitude of the level difference and combining the magnitude of the third adjustment parameter and/or the magnitude of the fourth adjustment parameter. If the display parameter, such as the display brightness value, which the electronic device should have at the second moment is obtained according to the third adjustment parameter and/or the fourth adjustment parameter; then, a brightness difference value between the display brightness value and the brightness value of the electronic equipment at the first moment is obtained, and then the brightness adjusting speed is configured based on the brightness difference value. The specific parameter adjustment rate can be obtained by the following principle:

if the level difference is large, in order to realize rapid adjustment, a corresponding parameter adjustment rate on an adjustment duration corresponding to the rapid adjustment can be set according to the size of the adjustment parameter, and at the moment, the parameter adjustment rate is relatively large, so that the display parameter of the electronic device can be rapidly adjusted to the brightness value corresponding to the brightness level corresponding to the second environment parameter;

if the level difference is small, in order to avoid the influence of the rapid adjustment on the comfort level of the eyes of the user, the corresponding parameter adjusting rate on the adjusting duration with the good eye comfort level can be set according to the size of the adjusting parameter, and at the moment, the parameter adjusting rate is relatively small, so that the display parameter of the electronic equipment is slowly adjusted to the brightness value corresponding to the brightness level corresponding to the second environment parameter.

Of course, in other embodiments, a smaller adjustment rate may be configured when the level difference is larger to avoid the fast adjustment affecting the comfort of the user's eyes.

Step 107: and adjusting the display parameters of the electronic equipment corresponding to the second environment parameters at least based on the parameter adjusting rate.

Specifically, in this embodiment, the display parameter of the electronic device corresponding to the second environment parameter is controlled to gradually adjust the brightness according to the parameter adjustment rate until the display parameter corresponds to the brightness value at the brightness level corresponding to the second environment parameter.

firstly, obtaining attribute information of a currently running application of the electronic equipment, wherein the attribute information represents an incidence relation between the currently running application and a display unit of the electronic equipment, such as a running dependency relation and the like, for example, a video playing has a strong dependency on the display unit of the electronic equipment, a network card setting has a weak dependency on the display unit of the electronic equipment and the like; the attribute information may be information such as an application identifier or an application type, and the association relationship between different application identifiers or application types and the display unit is different.

And then, judging the incidence relation between the currently running application and the display unit:

if the currently running application and the display unit have a first association relationship, such as an association relationship with a higher association degree, the display parameter can be adjusted by using the first adjustment parameter and/or the second adjustment parameter based on the first rate or at the first moment; if the degree of association between the currently running application and the display unit is high, indicating that the normal running of the currently running application or the usage experience brought to the user is high in the degree of dependence or sensitivity on the display unit, at this time, it is necessary to immediately start and adjust the display parameter at a fast rate corresponding to the brightness level corresponding to the first environmental parameter, so as to adjust the display parameter at a high first rate corresponding to the first adjustment parameter and/or the second adjustment parameter, or adjust the display parameter at the first moment by using the first adjustment parameter and/or the second adjustment parameter;

if the currently running application and the display unit have a second association relationship, for example, an association relationship with a lower association degree, the display parameter may be adjusted by using the first adjustment parameter and/or the second adjustment parameter based on the second rate or at the second time. If the degree of association between the currently running application and the display unit is low, indicating that the normal running of the currently running application or the usage experience brought to the user is low in dependence degree or sensitivity degree on the display unit, at this time, a certain time period may be delayed, for example, the second time may be started again, or the display parameter may be adjusted at a slower rate corresponding to the brightness level corresponding to the first environmental parameter, so in this embodiment, the display parameter may be adjusted at a lower first rate corresponding to the first adjustment parameter and/or the second adjustment parameter, or the display parameter may be adjusted at a second time after the first time by using the first adjustment parameter and/or the second adjustment parameter;

the first rate is different from the second rate, and the first time is different from the second time.

For example, the currently running application of the electronic device is an application type of screen output, such as a video application, and the like, in this embodiment, the display parameter may be immediately adjusted by using the first adjustment parameter and/or the second adjustment parameter at a faster rate and/or at a first time, so as to achieve the purpose of fast adjustment and avoid affecting the viewing experience of the user on the screen. For another example, the currently running application of the electronic device is an application type of data downloading, such as an application store and the like, for downloading and installing an application, in this embodiment, the display parameter may be adjusted at a satisfactory rate and/or at a second time after the first time by using the first adjustment parameter and/or the second adjustment parameter, so as to achieve the purpose of fast adjustment and avoid affecting the downloading of the application by the application store.

Therefore, in the embodiment, brightness adjustment of the electronic device on one or more adjustment parameters can be realized by using the brightness level corresponding to the environmental parameter without manually adjusting the brightness by the user, so that the brightness adjustment operation flow of the user is saved, and the operation complexity of the user is reduced.

It should be noted that, for the specific implementation of each unit in the apparatus of the present embodiment, reference may be made to the corresponding content in the foregoing, and details are not described here.

Referring to fig. 6, a schematic structural diagram of an electronic device according to a third embodiment of the present disclosure is provided, where the electronic device may be an electronic device capable of performing display output, such as a mobile phone with a display screen, a pad, a computer, and so on. The electronic device in this embodiment can be used to automatically control the display parameters of the electronic device, so as to reduce the complexity of brightness adjustment for the user.

Specifically, the electronic device in this embodiment may include the following structure:

the display 601 is used for outputting content, such as an output picture, and the display 601 has display parameters, such as a brightness parameter, a resolution, and the like.

A processor 602 configured to obtain a first environmental parameter at a first time; according to the brightness level corresponding to the first environment parameter, obtaining a first adjusting parameter and/or a second adjusting parameter corresponding to the brightness level; adjusting a display parameter of the display 601 corresponding to the first environment parameter based on at least the first adjustment parameter and/or the second adjustment parameter;

According to the above scheme, after the environmental parameters are obtained, the electronic device provided in the third embodiment of the present application obtains at least one corresponding adjustment parameter through the brightness level corresponding to the environmental parameters and representing the brightness value of the environmental parameters, and further adjusts the display parameters of the electronic device under the environmental parameters according to the adjustment parameters. Therefore, in the embodiment, brightness adjustment of the electronic device on one or more adjustment parameters can be realized by using the brightness level corresponding to the environmental parameter without manually adjusting the brightness by the user, so that the brightness adjustment operation flow of the user is saved, and the operation complexity of the user is reduced.

It should be noted that, for the specific implementation of the processor in the electronic device of the present embodiment, reference may be made to the corresponding contents in the foregoing, and details are not described here.

The following takes screen brightness adjustment on a mobile phone or a pad as an example to illustrate the technical scheme in the embodiment of the present application:

according to the scheme, according to different fitness and use habits (values of manually adjusting screen brightness) of each user under different ambient light, including ambient light, software application use habits, commonly used manually adjusted brightness values and the like, the information is collected and recorded, and the habit values of the user for independently adjusting the screen brightness, corresponding ambient light levels (environmental light levels are marked out in advance), related application scenes and the like are classified. Furthermore, the scheme is based on a certain rule, and the user-defined screen brightness is matched according to different ambient light levels and/or application scenes, as shown in the brightness configuration tables in tables 1 to 8 in the foregoing, so that when the ambient light change is detected, the brightness value to which the user is accustomed is actively adjusted. Therefore, according to the realization principle, the method and the device can be used for realizing personalized self-adaption to the respective specific screen brightness requirements of each user, the user experience is optimized to the maximum extent, the user does not need to additionally adjust manually, and the method and the device are more convenient and intelligent.

In one implementation, as shown in the schematic flow of the scheme shown in fig. 7, the screen brightness adjustment is implemented in the following manner in the scheme:

firstly, monitoring and recording a specific brightness value corresponding to the brightness of a screen manually changed by a user, collecting the ambient light condition through a light sensor and the like, and recording the difference between the brightness value manually adjusted by the user and the ambient light;

meanwhile, software information used by a user, such as application information of video playing or data downloading and the like, is collected, and whether the information represents a dependency relationship with a screen or not is judged;

then, the scene classification is carried out by integrating the sensor and the software information, and the optimized brightness adjusting scheme corresponding to the current user is generated according to different scenes, such as the adjusting schemes corresponding to the corresponding brightness levels shown in tables 1-8;

and finally, when the scene of the user using the mobile phone changes, the mobile phone adaptively adjusts the screen brightness to a corresponding brightness adjustment scheme.

Specifically, with reference to the luminance configuration tables in tables 1 to 8, the following illustrates the process of obtaining the luminance configuration table in this embodiment:

first, in the present solution, the range of the ambient light brightness is predefined hierarchically, such as 1 to 100 brightness levels, each of the brightness levels matches a default brightness value and a user-defined screen brightness value (the value is empty for the first time), and a brightness configuration table of the brightness level corresponding to the ambient light brightness, the user-defined screen brightness value, and a corresponding adjustment parameter is generated, as shown in table 9.

TABLE 9 Brightness configuration Table

Brightness level	Default brightness value	User-defined	First adjustment parameter	Second adjustment parameter
					1
2
					3
4
					5
6
					7
8
					9
…

The third column in table 9 may then be recorded by monitoring and recording the brightness value of the screen that the user manually changes. Meanwhile, the brightness parameters of the ambient light when the user changes the screen are collected through the sensor and matched to the corresponding brightness level. When the brightness of the screen is automatically adjusted for the first time, the brightness can be adjusted based on the default brightness value of the system, namely, when the brightness is automatically adjusted for the first time according to the brightness of the ambient light, the brightness is adjusted according to the default brightness value in the table.

When the user considers that the value does not meet the requirement, the screen brightness at the brightness level can be adjusted in a manual mode, the brightness value manually adjusted by the user is stored and filled in a third column corresponding to the corresponding brightness level in the brightness configuration table, the default brightness value corresponding to the corresponding brightness level is updated according to the third column, and the default brightness value is the brightness value which is obtained by integrating the historical adjustment of the user on the initial default brightness value.

After that, when the light sensor detects that the ambient light brightness in the environment where the user is located reaches the brightness range, the scheme automatically adjusts the screen brightness to the brightness value of the stored corresponding brightness level, so as to reach the brightness which the user is accustomed to. Meanwhile, the difference value between the brightness value manually adjusted for the first time by the user and the default brightness adjustment value of the system is used as a main reference coefficient (first adjustment parameter) of the user self-adaptive degree.

And then, according to the dynamic addition and subtraction configuration table of the main reference coefficient, default brightness values of other brightness levels which are not adjusted manually are adjusted, so that even if the brightness value corresponding to the brightness level is not adjusted manually by a user, the scheme can also actively adjust the default brightness values of other brightness levels according to the main reference coefficient of the sensitivity of the user to the ambient light.

And if the value dynamically adjusted through the first main reference coefficient still does not accord with the habit of the user, the user manually adjusts the brightness again, the difference value is separately recorded in the scheme, the two adjacent brightness levels are used as special intervals, and all the brightness values which are not manually adjusted in the characteristic interval are dynamically added and subtracted, namely, the second adjustment parameter, so as to refine the rule. And the operation is repeated in this way, so that the brightness configuration table gradually tends to be stable, and finally, the requirements of the user on the screen brightness under different ambient lights are covered.

It should be noted that, in the present solution, the brightness value automatically adjusted by the sensor for the first time may be based on the current system default brightness value of the mobile phone.
