[0034] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The description of the embodiments below refers to the accompanying drawings, which show by way of example the exemplary embodiments. Unless defined otherwise, all technical and scientific terms and abbreviations used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The drawings described are not necessarily to scale and have been exaggerated to illustrate various aspects of the embodiments.

[0035] In the drawings, identical or similar elements are denoted by the same reference numerals throughout the various drawings. The embodiments described are part of the disclosure, but not all of the embodiments. The embodiments described below by way of example are intended to explain the disclosure, and are not understood as limiting the disclosure. Based on the embodiments in the disclosure, all other embodiments obtained by a person of ordinary skill in the art without creative labor are within the scope of protection of the disclosure. The embodiments of the disclosure are described in detail below with reference to the drawings.

[0036] The method for adjusting screen brightness provided by the embodiments of the disclosure can be applied to the scenario of automatically adjusting screen brightness of a terminal. The method for adjusting screen brightness provided by the embodiments of the disclosure can be applied to devices with display functions such as mobile phones, tablet computers, and televisions.

[0037] With the development of terminal and network technologies, more and more users have the habit of watching videos, playing games, and reading novels on terminals. Due to the portability of terminals, the scenarios in which users use terminals are not fixed. When users use terminals in different scenarios, they need to constantly adjust the screen brightness to obtain the best display experience as the brightness of the scene changes.

[0038] In the related art, the screen brightness adjustment strategy of the terminal is realized on the basis of the historical data of the screen brightness obtained by the user after manually adjusting the screen brightness in the early stage. A more intelligent method for adjusting the screen brightness is to consider the current ambient light intensity and display scene and other external factors, thereby adjusting the screen brightness from multiple perspectives. In the related art, a large amount of historical data of the screen brightness adjusted by the user himself is needed as a reference basis to design a reasonable screen brightness adjustment strategy. However, it takes a lot of time to obtain a large amount of historical data of the screen brightness manually adjusted by the user in the early stage, which seriously lags behind the time of forming the screen brightness adjustment strategy. Moreover, when the terminal device is initially run by the user, the terminal does not store any historical data of the screen brightness as a reference. This will cause the user to have a bad experience in the initial stage of using the terminal.

[0039] Therefore, the present disclosure provides a method for adjusting screen brightness. A first user portrait is obtained. A second user portrait matching the first user portrait is determined. A screen brightness adjustment strategy used by the second user portrait is obtained. Further, a screen brightness adjustment strategy of the first user portrait is determined based on the screen brightness adjustment strategy used by the second user portrait. Based on this, even in the case that the screen brightness adjustment strategy available for the terminal is insufficient at the initial stage, the terminal can automatically adjust the screen brightness based on the existing screen brightness adjustment strategy, and the user experience is improved.

[0040] In the following disclosed embodiments, the user portrait can be a tagged user model abstracted from at least one tag information including user attributes, user preferences, living habits, user behaviors, occupations, etc.

[0041] In some possible embodiments of the present disclosure, the user who performs the terminal screen brightness adjustment can be referred to as a first user, for example, a user using a new terminal. The user who has performed the screen brightness adjustment (has the existing screen brightness adjustment configuration) can be referred to as a second user. The user portrait of the first user who performs the terminal screen brightness adjustment can be referred to as a first user portrait, and the user portrait of the second user who has the existing screen brightness adjustment configuration can be referred to as a second user portrait.

[0042] Figure 1 FIG. 1 is a flowchart of a method for adjusting screen brightness according to an example embodiment. Figure 1 As shown in FIG. 1, the method for adjusting screen brightness is used in a terminal, and includes the following steps.

[0043] In step S11, a first user portrait is obtained.

[0044] In some possible embodiments of the present disclosure, the user portrait (i.e., the first user portrait) of the terminal user can be obtained when the user (i.e., the first user) performs a screen brightness setting operation. For example, the first user portrait can be collected when the terminal first receives a user input for brightness adjustment (i.e., the terminal is first started for screen brightness adjustment). For another example, the first user portrait can be collected when a preset configuration switch is triggered. The preset configuration switch can be a configuration item switch (virtual switch and / or physical switch) on the terminal which is pre-set to enable the function corresponding to the method for adjusting screen brightness of the present disclosure. In some possible embodiments of the present disclosure, the user portrait (i.e., the first user portrait) of the terminal user can be obtained when the terminal user (i.e., the first user) first uses the terminal. For example, the first user portrait can be collected when the terminal is first started in a factory configuration state (including the first start of the terminal and the first start after the factory settings are restored).

[0045] For example, the first user portrait can be a user portrait of a user using the terminal, or can be a user portrait of a user registered with the terminal. In a general scenario, the user using the terminal and the user registered with the terminal are generally the same user.

[0046] In some possible embodiments of the present disclosure, the step of obtaining the first user portrait can include displaying prompt information. The portrait information input by the user based on the user portrait information item is collected to obtain the first user portrait. The prompt information includes information prompting the user to input the user portrait information item.

[0047] It can be understood that the prompt information at least includes the user's name, gender, age, region, and occupation, and the prompt information is not specifically limited in the embodiments of the present disclosure.

[0048] In some possible embodiments of the present disclosure, the prompt information is displayed when the terminal is started for the first time to adjust the screen brightness, or when the terminal is started for the first time in a factory configuration state, or when a preset configuration switch of the terminal is triggered. For example, when the user runs the terminal for the first time, a startup setting interface is displayed on the screen, and prompt information prompting the user to collect the portrait is displayed. The terminal manufacturer can set the personal information included in the user portrait by itself. In some possible embodiments, considering that the user portrait involves the user's personal privacy, the user needs to be informed in detail before the terminal collects the personal information, and the user's personal privacy is protected. If the user refuses to provide the personal information, the user needs to be informed that the terminal cannot start the function corresponding to the method for adjusting the screen brightness.

[0049] In the embodiments of the present disclosure, the user portrait information collected by terminal A includes the name: Zhang San, age: 34, gender: male, occupation: chef, and region: Beijing. The user portrait information collected by terminal B includes the name: Li Si, age: 23, gender: male, occupation: student, and region: Beijing. The user portrait information collected by terminal C includes the name: Wang Wu, age: 56, gender: female, occupation: teacher, and region: Beijing. The embodiments of the present disclosure obtain the user portrait of the user using the terminal by the user inputting the portrait information, for example, obtaining the first user portrait of the first user.

[0050] In the present disclosure, the prompt information is displayed, and the portrait information input by the user based on the user portrait information item is collected to obtain the target user portrait. Through the present disclosure, the terminal collects the user portrait of the user, which plays an auxiliary role in subsequent automatic adjustment of the screen brightness of the terminal.

[0051] In step S12, a second user portrait matched with the first user portrait is determined, and a screen brightness adjustment strategy used by the second user portrait is obtained.

[0052] In some possible embodiments of the present disclosure, the screen brightness adjustment strategy includes a screen brightness adjustment curve. The screen brightness adjustment curve is used to represent the screen brightness parameter corresponding to the brightness to be adjusted. The screen brightness adjustment curve, also referred to as a screen brightness curve, is a curve of the screen brightness parameter changing with a set independent variable.

[0053] In the embodiments of the present disclosure, the screen brightness adjustment strategy can be stored in the server and the terminal in the form of a data packet. The data packet of the screen brightness adjustment strategy can include the terminal application scenario, the user use time, the current environment brightness, the user manual brightness adjustment and other factors that can affect the screen brightness adjustment strategy, and the corresponding relationship between the screen brightness parameters determined by the above factors. For example, at 11:00 to 12:00 at night, the user browses a video on the terminal, at this time, the screen brightness adjustment strategy is set to 30%. At 11:00 to 12:00 in the daytime, the user reads a novel on the terminal, at this time, the screen brightness adjustment strategy is set to 80%.

[0054] In step S13, the screen brightness adjustment strategy of the first user portrait is determined based on the screen brightness adjustment strategy used by the second user portrait.

[0055] In the present disclosure, the first user portrait is obtained, the second user portrait matched with the first user portrait is determined, and the screen brightness adjustment strategy used by the second user portrait is obtained. Further, the screen brightness adjustment strategy of the first user portrait is determined based on the screen brightness adjustment strategy used by the second user portrait. Through the present disclosure, the existing screen brightness adjustment strategy can be adapted for the terminal user. Even in the case that the initial screen brightness adjustment strategy available for the terminal is insufficient, the terminal can also automatically adjust the screen brightness based on the existing screen brightness strategy, which can shorten the running-in period between the terminal and the user and improve the user experience.

[0056] In the following embodiment disclosure, how to determine the screen brightness adjustment strategy used by the second user portrait through the first user portrait will be described in detail.

[0057] Figure 2a is a flowchart of determining a second user portrait matched with a first user portrait according to an exemplary embodiment, as shown in Figure 2a As shown in the figure, determining a second user portrait matched with a first user portrait includes the following steps.

[0058] In step S22, the similarity between the first user portrait and each group of user portraits in the plurality of groups of user portraits is determined, to obtain a plurality of similarities.

[0059] In step S23, the user portrait corresponding to the maximum similarity in the plurality of similarities is taken as the second user portrait matched with the first user portrait.

[0060] In the embodiments of the present disclosure, after obtaining the first user portrait of the first user, the similarity between the first user portrait of the first user and the user portrait of the old user is calculated. The measurement method of the similarity between the first user portrait of the first user and the user portrait of the old user includes: Euclidean distance, cosine similarity, Pearson correlation coefficient, etc. In the embodiments of the present disclosure, the similarity measurement method is not specifically limited. In some possible embodiments of the present disclosure, in order to facilitate the similarity calculation, each label of the user portrait can be numbered according to a preset numbering rule, and then the user portrait is stored in the form of a numbered vector.

[0061] In some possible embodiments of the present disclosure, the user portrait obtained by the terminal can include personal information in five aspects of name, age, gender, occupation and region. For example, for the name information, the surname can be numbered, for example, the surname Zhang can be numbered as 1, the surname Li can be numbered as 2, and the rest of the surnames can be numbered in the same way; for example, the surname Smith can be numbered as 11, the surname Miller can be numbered as 12, and the surname Johnson can be numbered as 13, and the rest of the surnames can be numbered in the same way. For the age information, 0-10 years old can be numbered as 1, 11-20 years old can be numbered as 2, and the rest of the age ranges can be numbered in the same way. For the gender information, the number of males can be 1, the number of females can be 2, and the number of the third gender can be 3. For the occupation information, the number of scientists can be 1, the number of engineers can be 2, and the rest of the occupation numbers can be numbered in the same way. For the region information, the number of Beijing can be 1, the number of Shanghai can be 2, and the rest of the region numbers can be numbered in the same way.

[0062] In the embodiments of the present disclosure, the terminal stores the user portrait obtained by the terminal in the form of a numbered vector. For example, the user portrait information items of the user portrait of user Zhang San are as follows: name: Zhang San, age: 34, gender: male, occupation: chef, region: Beijing, and the user portrait in the terminal can be stored in the form of a numbered vector as [1, 4, 1, 5, 1]. The user portrait information items of the user portrait of the first user Li Si are as follows: name: Li Si, age: 23, gender: male, occupation: student, region: Beijing, and the user portrait in the terminal can be stored in the form of a numbered vector as [2, 3, 1, 8, 1]. The user portrait information items of the user portrait of the first user Wang Wu are as follows: name: Wang Wu, age: 56, gender: female, occupation: teacher, region: Beijing, and the user portrait in the terminal can be stored in the form of a numbered vector as [3, 4, 2, 3, 1].

[0063] In the embodiments of the present disclosure, based on the first user portrait obtained by the terminal and the second user portrait already existing in the server, the cosine similarity method is used to calculate the similarity. According to the similarity formula The similarity between the number vector of the first user and the number vector of the second user is calculated. If the value of the similarity is 1, it means that the portrait information of the first user is completely matched with the portrait information of the second user, the terminal stores the screen brightness adjustment strategy of the second user and uses the screen brightness adjustment strategy as the initial screen brightness adjustment strategy. If the value of the similarity is -1, it means that the portrait information of the new user is completely unmatched with the portrait information of the second user, the terminal re-matches the second user portrait information in the server and selects the screen brightness adjustment strategy of the second user with the highest similarity as the initial screen brightness adjustment strategy of the terminal.

[0064] It can be understood that the selection of the similarity measurement method, the user portrait, the setting of the number of each personal information, and the configuration of different weights in the above disclosed embodiments are defined by the terminal manufacturer, and the disclosure does not make specific limitations.

[0065] In the disclosure, the similarity between the first user portrait and each user portrait in the plurality of user portraits is determined to obtain a plurality of similarities. The user portrait corresponding to the maximum similarity in the plurality of similarities is taken as the second user portrait matched with the first user portrait. Through the disclosure, when a new user gets a new terminal, the terminal avoids collecting the screen brightness of the user using the terminal in different environments for a long time, reduces the time cost, and provides a good use experience for the new user in the early stage.

[0066] Figure 2b is a flowchart of determining a second user portrait matched with a first user portrait according to an example embodiment, as shown in Figure 2b , comprising the following steps.

[0067] Figure 2b Steps S21, S22 and S23 are included. S22 and S23 are similar to the embodiments of Figure 2a S22 and S23 in the disclosure, and therefore the disclosure will not make further explanations on S22 and S23.

[0068] In step S21, a plurality of user portraits are determined.

[0069] The plurality of user portraits are a plurality of different user portraits based on different screen adjustment strategies for adjusting the screen brightness.

[0070] In the disclosure, the step of determining the plurality of user portraits includes: determining the current use environment of the terminal; and determining the plurality of user portraits meeting the current use environment. The current use environment of the terminal can include the current location information, such as the region where the current location is located and / or the time zone where the current location is located, etc. The current use environment of the terminal can include the weather condition of the current location.

[0071] In the embodiments of the present disclosure, for example, the region where the user uses the terminal is determined, such as Beijing, Shanghai, Guangzhou, etc., and the screen brightness adjustment strategy is determined according to the region to conform to the multiple sets of user portraits of the region where the current user is located. The current use environment can also be the weather, for example, the terminal screen brightness will be higher on sunny days, and the terminal screen brightness will be lower on cloudy days.

[0072] In the present disclosure, the screen brightness adjustment strategy of the current first user is determined by comparing the user portrait similarity between different users. The basis is that if the user portrait similarity between different users is the largest, it means that the use behavior of the first user is closest to the use behavior of the second user with high similarity, and the screen brightness adjustment strategy set by the second user can be used as the screen brightness adjustment strategy for the first user to refer to in the early stage, that is, the brightness use habit of the first user can first refer to the brightness use habit of the similar user group in the early stage. Based on this, the method for adjusting the screen brightness provided by the present disclosure can solve the problem of insufficient screen brightness adjustment strategies for reference in the early stage of user use, shorten the time spent in forming the best automatic brightness curve, and improve the experience of the user using the terminal.

[0073] Figure 3 is a flowchart of a method for adjusting screen brightness according to an exemplary embodiment, as shown in Figure 3 The method for adjusting screen brightness is used in a terminal, and includes the following steps.

[0074] In step S31, the screen brightness adjustment parameters corresponding to the screen brightness adjustment performed by the user on the terminal within a predetermined time period are monitored.

[0075] In step S32, the screen brightness adjustment strategy of the first user portrait is updated based on the screen brightness adjustment parameters.

[0076] In the embodiments of the present disclosure, the screen brightness adjustment strategy is adjusted based on the screen brightness adjusted by the user within a predetermined time period. For example, in the terminal, there is already a matched screen brightness adjustment strategy, and based on the use habits and use scenarios of the new user, the automatically imported screen brightness adjustment strategy is fine-tuned and optimized by using the conventional technology. For example, the automatic brightness adjustment is performed in combination with the ambient light brightness, the user's manual brightness adjustment, the application program used, and the use time. If the user has manually adjusted the automatic brightness multiple times at a certain time, under a certain ambient light brightness, and for a certain application program, the recommended automatic screen brightness adjustment strategy for the application program will be adjusted, and the screen brightness adjustment strategy close to the time and ambient light brightness will be adjusted to the average of the screen brightness adjustment strategies after the user's manual adjustment. For example, user A has the habit of using a short video application program in the dark every night, and if the user adjusts the brightness to be too low on the first day and the second day, then when the user uses the short video application program in the dark environment on the third day, the screen brightness will be the average of the screen brightness adjustment strategies after the user's manual adjustment on the previous two days, so as to automatically increase the screen brightness.

[0077] In the present disclosure, the screen brightness adjustment parameters performed by the user on the terminal within a predetermined time period are monitored, and the screen brightness adjustment strategy of the first user portrait is updated based on the screen brightness adjustment parameters. Through the present disclosure, in the case where the terminal already has an initial screen brightness adjustment strategy, the initial screen brightness adjustment strategy can also be updated based on the adjustment of the screen brightness parameters by the user later, so that the strategy is more suitable for the user to use.

[0078] Figure 4 A schematic diagram of automatic screen brightness adjustment of a terminal is shown. As shown in FIG. 1, the terminal is in a dark environment, and the user manually adjusts the screen brightness to be too low. The terminal automatically adjusts the screen brightness to be higher than the initial screen brightness adjustment strategy. Figure 4As shown, the first user uses the terminal. When the first user runs the terminal for the first time, the first user is prompted to fill in the personal portrait information. If the first user chooses to refuse to collect the personal portrait information, the first user is prompted to manually adjust the screen brightness in advance. If the first user fills in the personal portrait information (first user portrait information), the terminal analyzes the first user portrait information and stores the obtained first user portrait information in the form of a number vector, for example, the first user portrait information can include but is not limited to name, gender, age, etc. The terminal uses a similarity measurement method, for example, Euclidean distance, cosine similarity, etc., to sequentially calculate the similarity between the number vector of the first user and the number vector of the second user already stored in the server, and selects the screen brightness adjustment strategy corresponding to the second user with the highest similarity as the initial screen brightness adjustment strategy of the first user terminal, and imports it into the terminal for use. According to the use habit of the first user, the initial screen brightness adjustment strategy is optimized to obtain a screen brightness adjustment strategy suitable for the first user personally. Based on this, the terminal in advance matches the second user with the highest similarity for the first user by obtaining the user portrait, and sends the screen brightness adjustment strategy of the second user to the terminal of the first user, thereby improving the use experience of the first user in advance. Since the screen brightness adjustment strategy sent to the terminal of the first user is more consistent with the expectations of the first user, only a small amount of time is required to fine-tune and optimize the screen brightness adjustment strategy according to the use habit of the first user, so that the screen brightness adjustment strategy meeting the needs of the first user can be obtained, thereby reducing the time cost.

[0079] Based on the same concept, the present disclosure also provides a device for adjusting screen brightness.

[0080] It can be understood that the device for adjusting screen brightness provided by the embodiments of the present disclosure comprises a hardware structure and / or a software module corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiments of the present disclosure, the embodiments of the present disclosure can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is executed by hardware or computer software driven hardware depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of the embodiments of the present disclosure.
