An embodiment of the present invention provides a method for adjusting a terminal screen brightness, and referring to fig. 2, fig. 2 is a flowchart illustrating a first embodiment of a method for adjusting a terminal screen brightness according to the present invention.
In this embodiment, the method for adjusting the brightness of the terminal screen includes the following steps:
step S10: when a brightness adjusting instruction is detected, acquiring terminal operation parameters and application information of a current operation application of the terminal;
it should be noted that the main execution body of this embodiment is the terminal screen brightness adjustment device, where the terminal screen brightness adjustment device may be an electronic device such as a mobile phone and a tablet computer, or may also be another device that can achieve the same or similar functions.
It should be noted that the instruction is a command instructing the computer to perform a certain operation, and the brightness adjustment instruction may be understood as a command notifying that the brightness adjustment operation needs to be performed, and when the brightness adjustment instruction is detected, the terminal screen brightness adjustment device receives the brightness adjustment operation that needs to be performed, and then the terminal screen brightness adjustment program may be invoked to perform the terminal screen brightness adjustment method to perform the brightness adjustment on the terminal screen.
In actual use, the brightness adjustment instruction may be an instruction generated when detecting that a terminal operation parameter and a terminal operation application program change, or may be an instruction received from the server, the terminal operation parameter may be each parameter of the terminal during operation, the terminal operation application may be an application currently running at the current time of the terminal, and the application information may be a unique identifier of the terminal operation application.
For example: when detecting that the terminal operation parameters and the terminal operation application program change, a brightness adjusting instruction or a brightness adjusting instruction sent by a server is received, and when detecting the brightness adjusting instruction, the current residual electric quantity value of the terminal during the terminal operation, the operation mode of the application currently running by the terminal, the current ambient light intensity collected by the terminal and the application unique code (application ID) of the application currently running by the terminal are obtained.
Step S20: determining a screen brightness curve function according to the terminal operation parameters and the application information;
it should be noted that, according to the personal use habit of the user, under the condition that the terminal runs different applications and different terminal running parameters, the corresponding screen brightness curve function can be set, and when brightness adjustment is needed, the corresponding screen brightness curve function can be searched according to the different applications and different terminal running parameters which are run by the terminal.
Further, in order to better determine the screen brightness curve function according to the terminal operation parameter and the application information, the step of determining the screen brightness curve function according to the terminal operation parameter and the application information in this embodiment may be:
searching a brightness curve function set corresponding to the application information in an application brightness curve function set; reading a terminal electric quantity parameter and application operation mode information from the terminal operation parameter; and searching a corresponding brightness curve function in the brightness curve function set according to the terminal electric quantity parameter and the application running mode information.
It should be noted that the application brightness curve function set may be a set constructed in advance according to each application information established by analyzing the use habits of the user and a brightness curve function set corresponding to the application information, the corresponding brightness curve function set may be directly found in the corresponding application brightness curve function set through the application information, the brightness curve function set may include a plurality of brightness curve functions set according to different terminal electric quantity parameters and different application operation mode information, each brightness curve function may have a corresponding terminal electric quantity interval, and the corresponding brightness curve function may be directly found through the terminal electric quantity parameters and the application operation mode.
In actual use, the brightness curve function set corresponding to the application information can be directly found in the application brightness curve function set according to the application information, and then the corresponding brightness curve function can be found in the brightness curve function set according to the actual terminal electric quantity parameter and the application operation mode.
For example: the application information is A, a brightness curve function set B corresponding to the application information A is found in the application brightness curve function set according to the application information A, and the brightness curve function set B comprises F 1 、F 2 、F 3 、F 4 Four brightness curve functions are screened according to the terminal electric quantity parameters and the application operation mode information, and finally F is determined 2 As a function of the corresponding luminance curve.
Step S30: and adjusting the brightness of the terminal screen according to the current environment brightness and the screen brightness curve function.
In actual use, after searching for the corresponding screen brightness curve function according to different applications and different terminal operation parameters of the terminal, the current environment brightness acquired by the terminal can be acquired, then the current environment brightness is input into the screen brightness curve function to calculate the corresponding target screen brightness value, and then the terminal screen brightness is adjusted to the target screen brightness value.
For example: acquiring the current environment brightness b acquired by the terminal, inputting the environment brightness b into a screen brightness curve function F (b), and calculating to obtain a target screen brightness value of 40%, wherein if the terminal screen brightness is higher than 40%, the terminal screen brightness is reduced to 40%, and if the terminal screen brightness is lower than 40%, the terminal screen brightness is increased to 40%.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and in a specific application, a person skilled in the art may set the technical solution as needed, and the present invention is not limited thereto.
According to the method, when a brightness adjusting instruction is detected, the current terminal operation parameters and the application information of the application currently running in the terminal are obtained, the corresponding screen brightness curve function is determined according to the terminal operation parameters and the application information, and then the brightness of the screen is adjusted according to the current environment brightness and the screen brightness curve function.
Referring to fig. 3, fig. 3 is a flowchart illustrating a method for adjusting the brightness of a terminal screen according to a second embodiment of the present invention.
Based on the first embodiment, before the step S10, the method for adjusting the screen brightness of the terminal according to this embodiment further includes:
step S01: acquiring a brightness data set preset by a user, and performing data grouping on the brightness data set according to application information to obtain a brightness data subset;
it should be noted that the brightness data set may be a data set collected when a user manually sets the brightness of the terminal screen, the set may be updated by collecting data in real time when it is detected that the user manually sets the brightness of the terminal screen, and each brightness data may include information such as application information, ambient brightness, brightness set by the user, a parameter of the electric quantity of the terminal during collection, and an application operation mode of the current operation application of the terminal during collection.
In practical use, the data in the luminance data set may be grouped according to different application information of each data in the luminance data set, and the luminance data set is divided into a plurality of luminance data subsets, where each luminance data subset corresponds to one application information.
For example: the total number of the application information is 4, which is a, B, C, and D, respectively, and the luminance data set is subjected to data grouping according to the application information, so as to obtain a data subset corresponding to each application information, for example: a corresponds to the data subset L A B corresponds to the data subset L B C corresponds to the data subset L C D corresponds to the data subset L D 。
Step S02: acquiring a corresponding brightness curve function set according to the brightness data subset;
it should be noted that each application information has a corresponding initial luminance curve function set, and the luminance data subsets are obtained by grouping according to the application information, so that the corresponding initial luminance curve function sets can be obtained, and then the corresponding luminance curve function sets can be obtained by further processing according to the luminance data subsets.
Further, in order to obtain the brightness curve function set, the step of obtaining the corresponding brightness curve function set according to the brightness data subset in this embodiment may be:
acquiring an initial brightness curve function set corresponding to the brightness data subset; and optimizing the brightness curve function in the initial brightness curve function set to obtain an optimized brightness curve function set.
It should be noted that the initial brightness curve function set includes a plurality of brightness curve functions, and the plurality of brightness curve functions may be obtained by analyzing behaviors of a large number of different users for the same application under different terminal operating parameters.
It can be understood that, when the initial function obtained by analyzing a large number of different user behaviors is specific to a specific user, the initial function can be optimized and adjusted according to personal use data of the user, so that the initial function is more in line with personal use habits of the user, and therefore, after the brightness curve function in the initial brightness curve function set is optimized according to the brightness data subset, the obtained brightness curve function in the optimized brightness curve function set which is buried thickly is more in line with the personal use habits of the user.
Further, in order to describe how to optimize the luminance curve function in the initial luminance curve function set, the step of optimizing the luminance curve function in the initial luminance curve function set in this embodiment may be:
acquiring application running mode information corresponding to each brightness data in the brightness data subset; searching a first brightness curve function and a second brightness curve function corresponding to the initial brightness curve function set according to the application running mode information; determining a target optimization function according to the first brightness curve function, the second brightness curve function and the brightness data; and optimizing the target optimization function according to the brightness data.
It should be noted that the operation modes of the same application are generally divided into two types: the brightness curve function can be generally divided into two types according to the difference of the electric quantity for different modes: a high-power luminance curve function and a low-power luminance curve function, the first luminance curve function may be the high-power luminance curve function, and the second luminance curve function may be the low-power luminance curve function.
In actual use, a high-power luminance curve function and a low-power luminance curve function corresponding to the operation modes can be found in the initial luminance curve function set according to the actual operation mode applied in operation, then the high-power luminance curve function or the low-power luminance curve function is determined as a target optimization function according to the luminance data, then the target optimization function is optimized by using the luminance data, and a terminal power interval corresponding to the function can be adjusted according to all luminance data actually used by the luminance curve function.
In practical use, the luminance data may be used to optimize the target optimization function, and the target optimization function may be further fit and adjusted by using algorithms such as a least square method, a lagrange interpolation method, a newton interpolation method, and the like, which is not limited in this embodiment.
For example: if the application operation mode corresponding to the brightness data a is a dark mode, the corresponding first brightness curve function F can be found in the initial brightness curve function set 1 And a second luminance curve function F 2 According to the brightness data A and the first brightness curve function F 1 And a second luminance curve function F 2 Analyzing to determine a first brightness curve function F 1 For the target optimization function, a least squares method is used to perform a first luminance curve function F based on the luminance data A 1 Further fitting adjustments are made.
Further, in order to accurately determine the objective optimization function, the step of determining the objective optimization function according to the first luminance curve function, the second luminance curve function and the luminance data in this embodiment may include:
calculating according to the brightness data and the first brightness curve function to obtain a first difference relative value; calculating according to the brightness data and the second brightness curve function to obtain a second difference relative value; and determining an objective optimization function from the first brightness curve function and the second brightness curve function according to the first difference relative value and the second difference relative value.
It should be noted that the difference relative value may represent a degree of engagement between the luminance data and the luminance curve function, a first difference relative value between the luminance data and the first luminance curve function is calculated, a second difference relative value between the luminance data and the second luminance curve function is calculated, and then the first difference relative value and the second difference relative value are compared, so that the luminance curve function more engaged with the luminance data may be determined, and thus, the target optimization function may be determined.
It should be noted that, when the relative difference value is greater than a certain value, it indicates that the degree of matching between the luminance data and the function is very poor, and the luminance data is invalid data. Therefore, a relative difference threshold can be set according to actual conditions, the relative difference value is compared with the relative difference threshold, and if the relative difference value is larger than the relative difference threshold, the brightness data can be discarded.
In practical use, the calculation formula of the relative gap value can be as follows:
D＝|f-F n (b)|/f
wherein D is the relative difference value, F is the user-adjusted brightness value, b is the environment brightness value, and F n (b) As a function of the luminance profile.
In actual use, when the first gap relative value and the second gap relative value are both larger than or equal to a preset gap relative threshold value, the target optimization function is abandoned to be selected;
when the first difference relative value is smaller than a preset difference relative threshold value and the second difference relative value is larger than or equal to the preset difference relative threshold value, taking the first brightness curve function as a target optimization function;
when the second difference relative value is smaller than a preset difference relative threshold value and the first difference relative value is larger than or equal to the preset difference relative threshold value, taking the second brightness curve function as a target optimization function;
when the first difference relative value and the second difference relative value are both smaller than a preset difference relative threshold value, comparing the first difference relative value with the second difference relative value;
when the first difference relative value is smaller than or equal to the second difference relative value, taking the first brightness curve function as a target optimization function;
when the first gap relative value is larger than the second gap relative value, the second brightness curve function is used as the target optimization function
For example: presetting a relative difference threshold value as 10%;
if the relative value of the first difference is 11% and the relative value of the second difference is 13%, discarding the brightness data and abandoning the selection of the objective optimization function.
And if the first difference relative value is 11% and the second difference relative value is 7%, selecting the second brightness curve function as the target optimization function.
And if the first difference relative value is 7% and the second difference relative value is 11%, selecting the first brightness curve function as the target optimization function.
If the first difference relative value is 7% and the second difference relative value is 9%, the first luminance curve function is selected as the objective optimization function.
And if the first difference relative value is 9% and the second difference relative value is 7%, selecting the second brightness curve function as the target optimization function.
Step S03: and constructing an application brightness curve function set according to the brightness curve function set and the application information corresponding to each brightness data subset.
It can be understood that the luminance data subsets correspond to the application information one to one, and the luminance curve function set corresponds to the luminance data subsets one to one, so that the application luminance curve function set can be constructed according to the application information and the luminance curve function set, and the constructed application luminance curve function set can directly find the luminance curve function set corresponding to the application information according to the application information.
In practical use, the construction of the set of application brightness curve functions can adopt Key: the Value-form set is constructed, for example, by using a HashMap, hashTable, and other types of sets, using the application information as Key, and using the luminance curve function set as Value, the luminance curve function set may be stored by using an ArrayList, linkedList, and other types of sets, and the set element of the luminance curve function set is a luminance curve function.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and in a specific application, a person skilled in the art may set the technical solution as needed, and the present invention is not limited thereto.
In the embodiment, the initial brightness curve function set corresponding to each application information is optimized according to the personal use habit of the user to obtain the brightness curve function set corresponding to each application information, and then the application brightness curve function set is constructed according to the application information and the brightness curve function set corresponding to the application information, wherein each brightness curve function in the application brightness curve function set constructed according to the method of the embodiment is more in line with the personal use habit of the user.

Based on the first embodiment, before the step S10, the method for adjusting the screen brightness of the terminal in this embodiment further includes:
step S01': and when detecting that the terminal running application or the terminal running parameter is changed, generating a brightness adjusting instruction.
It should be noted that the terminal operation parameters may include operation parameters such as a current electric quantity of the terminal, an application operation mode of the terminal operation application, and an ambient light intensity collected by the terminal, and when it is detected that the terminal operation application or/and the terminal operation parameters are changed, the terminal operation application or/and the terminal operation parameters may be matched with a preset brightness adjustment condition according to various parameters, and when the changed parameters of the terminal operation application or the terminal operation parameters meet the preset brightness adjustment condition, a brightness adjustment instruction is generated.
In actual use, the terminal running application and the terminal running parameters can be monitored in real time, and when one of the following conditions is met, a brightness adjusting instruction is generated:
when detecting that an electric quantity interval corresponding to the current electric quantity of the terminal is changed, namely, the electric quantity interval is switched from a high electric quantity interval to a low electric quantity interval, or the electric quantity interval is switched from the low electric quantity interval to the high electric quantity interval;
when detecting that the current terminal runs application change;
when detecting that the application running mode of the current terminal running application is changed;
when the change of the intensity of the ambient light collected by the terminal is detected.
For example: according to the using habit of a user, the terminal electric quantity is in a low electric quantity interval when the electric quantity is lower than 30%, and is in a low electric quantity interval when the electric quantity is higher than 30%, when the electric quantity is lower than 30% and is lower than 30%, a brightness adjusting instruction is generated, and when the electric quantity is higher than 30% and is higher than 30%, the brightness adjusting instruction is generated; when the current terminal runs an application and is switched from an application A to an application B, a brightness adjusting instruction is generated; when the application operation mode of the current terminal operation application is switched from the dark black mode to the common mode, a brightness adjusting instruction is generated, and when the application operation mode of the current terminal operation application is switched from the common mode to the dark black mode, a brightness adjusting instruction is generated; and when the ambient light intensity collected by the terminal is changed from the light intensity A to the light intensity B, generating a brightness adjusting instruction.
It should be understood that the above is only an example, and the technical solution of the present invention is not limited in any way, and in a specific application, a person skilled in the art may set the technical solution as needed, and the present invention is not limited thereto.
In the embodiment, by monitoring the terminal running application and the terminal running parameter in real time, when the change of the terminal running parameter or/and the terminal running application meets the brightness adjustment condition, a brightness adjustment instruction is generated, then when the brightness adjustment instruction is received, the current terminal running parameter and the application information of the application currently running at the terminal are obtained, then the corresponding screen brightness curve function is determined according to the terminal running parameter and the application information, then the brightness adjustment is performed on the screen according to the current ambient brightness and the screen brightness curve function, and whether the brightness adjustment is needed or not can be quickly judged.
