[0028] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0029] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0030] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0031] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0032] The adjustment algorithm for the display screen brightness of electronic devices is generally based on subjective adjustment by human will, and does not consider other factors that affect the screen brightness. As a result, the determined screen brightness is inaccurate, which makes it unsuitable for relevant scenarios and unable to accurately adjust the screen brightness to a brightness that meets user needs, thereby reducing the user's visual experience.

[0033] To this end, one aspect of the present application provides a method for determining screen brightness. Figure 1 , Figure 1 1 is a flow chart of a method for determining screen brightness shown in an exemplary embodiment of the present application. The determination method at least includes S110 to S120, which are described in detail as follows:

[0034] S110: Determine the current initial brightness according to the brightness adjustment instruction, the current screen parameters and the current environmental parameters; wherein the brightness adjustment instruction is an instruction issued by the user to adjust the screen brightness; the current screen parameters include adjacent historical brightness, and the adjacent historical brightness is the screen brightness at the adjacent previous historical moment of the current moment.

[0035] The brightness adjustment instruction is an instruction indicating that the user desires to adjust the screen brightness, for example, indicating an operation of increasing, decreasing, or maintaining the screen brightness. In some embodiments, the brightness adjustment instruction includes the intensity of the brightness adjustment, and data for increasing / decreasing the brightness, and may also include a target brightness value that is expected to be achieved.

[0036] The current screen parameters are the screen-related parameters at the current moment, which characterize the parameters related to the intrinsic level of the screen, including but not limited to screen resolution, screen backlight brightness, color and area of ​​each display area, and other parameters.

[0037] The current environmental parameters are the relevant parameters of the environment in which the screen is located at the current moment. They are parameters that characterize the external level of the screen, including but not limited to ambient weather, satellite position of the electronic device described on the screen, ambient light intensity, current time and other parameters.

[0038] In some embodiments, the current initial brightness is determined not by using adjacent historical brightness, but by the screen brightness before the screen brightness is adjusted when the subject of the present application receives a brightness adjustment instruction issued by the user, that is, it can be the screen brightness of any historical moment in the preceding historical moment of the current moment. In order to better meet the user's adjustment expectations, this embodiment determines the current initial brightness based on adjacent historical brightness (that is, the screen brightness of the previous historical moment adjacent to the current moment).

[0039] In some embodiments, the identity information of the current user needs to be identified to determine the adjacent historical brightness and the specified historical brightness to be adapted. For example, the identity information of the current user is matched with the preset identity information; if the match is successful, the adjacent historical brightness and the specified historical brightness are determined from the historical parameters corresponding to the preset identity information that successfully matches; if the match fails, the adjacent historical brightness and the specified historical brightness are determined from the historical parameters corresponding to the general identity information. Among them, the general identity information is similar to the identity information of the visitor, and there is no need to record and save the identity information of the relevant parameters.

[0040] In this embodiment, if the match is successful, it indicates that the historical parameters of the current user are recorded. The selection of the historical parameters can be more suitable for the current user's operating habits and visual perception, can reduce the adjustment operation and / or adjustment intensity to a certain extent, and can quickly determine the screen brightness that is suitable for the current user's visual sense. If the match fails, it indicates that the current user is not a preset user recorded and stored, and the relevant historical parameters are not recorded. Then, the adjacent historical brightness and the specified historical brightness can be determined from the default historical parameters (i.e., the historical parameters corresponding to the general identity information). The two historical parameters do not have personalized identity characteristics, so as to serve as the bottom-line historical parameters for the method of determining the screen brightness of this application.

[0041] S120: If the brightness adjustment instruction represents an increase / decrease operation on the screen brightness, the current target brightness of the screen display is determined based on the current initial brightness and the specified historical brightness; wherein the specified historical brightness is the screen brightness at consecutive historical moments adjacent to the current moment.

[0042] If the brightness adjustment instruction represents an increase / decrease operation on the screen brightness, it represents that the user desires to adjust the original screen brightness, and a brightness correction value can be calculated based on the current initial brightness and the specified historical brightness to correct the current initial brightness or the specified historical brightness to obtain the current target brightness of the screen display. The specified historical brightness can be the historical screen brightness within a continuous month before the current moment.

[0043] If the brightness adjustment instruction indicates that the screen brightness is not increased / decreased (i.e., the screen brightness is maintained unchanged), it indicates that the user expects to maintain the original screen brightness (e.g., adjacent historical brightness), that is, the user expects the screen brightness presented on the visual level to remain unchanged, but because the current scene has changed compared to the historical scene (e.g., the screen parameters and / or environmental parameters have changed), if the original screen brightness is used for display, the visual effect that the user expects to present cannot be achieved. For this reason, the present application does not directly use the original screen brightness as the current target brightness, but uses the current initial brightness as the current target brightness. Among them, the current initial brightness not only takes into account the brightness adjustment instruction, but also combines the current screen parameters and the current environmental parameters. The screen is displayed at the current target brightness, which can make the current screen brightness felt by the user at the visual level the same as the original screen brightness, so as to meet the user's visual needs to maintain the screen brightness unchanged. Accordingly, in some embodiments, if the current screen brightness is the same as the original screen brightness, but because the scenes (screen parameters and / or environmental parameters) of the two are different, the user will think that the brightness of the two is different at the visual sensory level.

[0044] In the process of adjusting the screen brightness in real time according to the brightness adjustment instruction, this embodiment introduces screen parameters and environmental parameters, combines the intrinsic and external parameters of the screen to accurately determine the initial brightness, and combines the operation type represented by the brightness adjustment instruction and the relevant historical brightness to correct the determined initial brightness to obtain the target brightness suitable for the current scene, so as to improve the user's visual experience.

[0045] Since the related technology does not consider the impact of screen parameters and environmental parameters on screen brightness during the calculation of screen brightness, those skilled in the art cannot know how to calculate the current initial brightness in this application based on this.

[0046] To this end, in another exemplary embodiment of the present application, how to determine the current initial brightness according to the brightness adjustment instruction, the current screen parameters and the current environment parameters is described in detail. Figure 2 , Figure 2 is based on Figure 1 The exemplary embodiment shown is a flow chart of another method for determining screen brightness. The determination method is as follows Figure 1 The S110 shown includes at least S210 to S230, which are described in detail as follows:

[0047] S210: Determine the value and sign of the adjustment parameter corresponding to the brightness adjustment instruction according to the brightness adjustment instruction representing the operation on the screen brightness; wherein the brightness increase operation corresponds to the positive adjustment parameter, and the brightness decrease operation corresponds to the negative adjustment parameter.

[0048] The brightness adjustment instruction includes but is not limited to the value of the adjustment parameter. If the brightness adjustment instruction represents an operation to increase the brightness of the screen, the adjustment parameter is determined to be a positive number, otherwise it is a negative number. The positive and negative distinction is used to represent the positive / negative impact of the adjustment parameter on the current initial brightness calculation process. Among them, positive / negative only represents the definition of relativity, to represent the different impacts on the current initial brightness, and there is no good / bad distinction.

[0049] S220: Numerically process each parameter in the current screen parameter and the current environment parameter, and construct a current state vector according to each obtained numerical value.

[0050] The current state vector is a state vector represented by the relevant parameters at the current moment. The vector includes numerical values ​​of each relevant parameter after numerical processing, that is, includes multiple sub-vectors.

[0051] Exemplarily, the current screen parameters include the current screen display brightness parameter (S1 after numerical processing) and the screen backlight brightness parameter (S2 after numerical processing); the current environmental parameters include the current light intensity parameter (S3 after numerical processing), the current ambient weather parameter (S4 after numerical processing), the current time parameter (S5 after numerical processing), and the current position parameter (S6 after numerical processing), thereby constructing the current state vector S = [S1, S2, S3, S4, S5, S6].

[0052] S230: Calculate the current initial brightness according to the adjustment parameters and the current state vector.

[0053] For example, the brightness adjustment instruction represents an operation of increasing the screen brightness, and its adjustment parameter is A + , S = [S1, S2, S3, S4, S5, S6] and A +Substitute the preset brightness calculation function Q to calculate the current initial brightness Q(S, A + ).

[0054] If the brightness adjustment instruction indicates that the screen brightness will not be increased / decreased; the adjustment parameter corresponding to the brightness unchanged operation is zero; the zero value and the current state vector are input into the preset brightness calculation function to calculate the current initial brightness; wherein the current state vector includes multiple sub-vectors representing the current light intensity parameters, the current ambient weather parameters, the current position parameters, and the current time parameters; the current initial brightness is used as the current target brightness displayed on the screen.

[0055] Exemplarily, the current light intensity parameter (S3 after numerical processing), the current ambient weather parameter (S4 after numerical processing), the current position parameter (S6 after numerical processing), and the current time parameter (S5 after numerical processing); A=0, S'=[S3, S4, S6, S5], are substituted into the preset brightness calculation function Q to calculate the current initial brightness Q(S, 0).

[0056] If the brightness adjustment instruction indicates that the screen brightness will not be increased / decreased (A=0), it indicates that the user expects to maintain the original screen brightness, that is, the user expects the screen brightness presented at the visual level to remain unchanged, but because the current scene has changed compared to the historical scene (for example, the screen parameters and / or environmental parameters have changed), if the original screen brightness is used for display, the visual effect that the user expects to present cannot be achieved. For this reason, the present application does not directly use the original screen brightness as the current target brightness, but uses the current initial brightness as the current target brightness. Among them, the current initial brightness not only takes into account the brightness adjustment instruction, but also combines the current screen parameters and the current environmental parameters. The screen is displayed at the current target brightness, which can make the current screen brightness perceived by the user at the visual level the same as the original screen brightness, so as to meet the user's visual needs to maintain the screen brightness unchanged.

[0057] In another exemplary embodiment of the present application, it is described in detail how to numerically process each parameter in the current screen parameter and the current environment parameter. For details, please refer to Figure 3 , Figure 3 is based on Figure 2 The exemplary embodiment shown is a flow chart of another method for determining screen brightness. The determination method is as follows Figure 2 The S220 shown includes at least S310 to S330; wherein the current screen parameters also include area parameters and color parameters of each display area, which are described in detail as follows:

[0058] S310: performing product operations on the area parameters and color parameters of each display area and their corresponding preset weight coefficients respectively, and calculating a plurality of products; wherein the reflectivity of the color represented by the color parameter is proportional to the corresponding preset weight coefficient.

[0059] During the process of technical improvement, the present application discovered that different color areas and color block sizes in the display screen will affect the user's visual senses. Colors with higher reflectivity are more obvious at the visual level and will give people a brighter visual experience.

[0060] This embodiment sets a larger preset weight coefficient for colors with high reflectivity to increase the influence of colors with high reflectivity on parameter quantification, and at the same time divides the display area and combines the area parameters of each display area to calculate the numerical value corresponding to each display area.

[0061] S320: performing a sum operation on the multiple products to obtain a value corresponding to each display area.

[0062] Because there may be multiple colors in a display area, the product of the corresponding color parameter and area parameter is calculated for each color block, and the products corresponding to all the color blocks are added together to obtain the value corresponding to the display area. Similarly, the values ​​corresponding to each display area are calculated.

[0063] S330: performing a sum operation on the values ​​corresponding to the respective display areas to obtain the values ​​corresponding to all the display areas.

[0064] By adding up all the values ​​corresponding to each display area, the values ​​corresponding to all the display areas, that is, the values ​​corresponding to the entire display area in the display screen, can be quickly obtained.

[0065] In another exemplary embodiment of the present application, it is described in detail how to determine the current target brightness of the screen display based on the current initial brightness and the specified historical brightness. For details, please refer to Figure 4 , Figure 4 is based on Figure 1 The exemplary embodiment shown is a flow chart of another method for determining screen brightness. The determination method is as follows Figure 1 The S120 shown includes at least S410 to S430, which are described in detail as follows:

[0066] S410: summing the product of the current initial brightness and the first constant and the adjustment correction parameter to obtain a sum value; wherein the adjustment correction parameter is a parameter determined according to the brightness adjustment instruction and the historical brightness adjustment instruction.

[0067] The first constant is a constant that can be adaptively adjusted according to different scenarios. In some embodiments, in order to make the parameters calculated in real time more accurate, the calculation model is trained in real time, so that the first constant and the second constant described below can change adaptively.

[0068] Adjusting the correction parameter is similar to calculating the reward value based on the relevant historical brightness parameter and the reward function, so as to introduce the relevant historical brightness parameter for numerical correction.

[0069] In some embodiments, the historical brightness adjustment instruction includes a historical brightness increase instruction and a historical brightness decrease instruction. If the brightness adjustment instruction represents an increase operation on the screen brightness, the adjustment correction parameter is determined according to the historical brightness increase instruction; if the brightness adjustment instruction represents a decrease operation on the screen brightness, the adjustment correction parameter is determined according to the historical brightness decrease instruction; wherein each relevant instruction carries a historical brightness value, and in order to balance the calculation influence between different positive and negative parameters, the number of historical brightness increase instructions and historical brightness decrease instructions is the same. For example: if the brightness adjustment instruction represents a brightness increase operation, the average value is calculated based on all historical brightness (the number is 100) in the 100 historical brightness increase instructions before the current moment as the adjustment correction parameter. For another example: if the brightness adjustment instruction represents a brightness decrease operation, the average value is calculated based on all historical brightness (the number is 100) in the 100 historical brightness decrease instructions before the current moment as the adjustment correction parameter. In other embodiments, the number of historical brightness increase instructions and historical brightness decrease instructions is not limited to the same, and the respective calculation parameters are selected by limiting the same historical duration. For example, the average value of all historical brightness calculated from the historical brightness increase / decrease instructions within one month before the current moment is used as the adjustment correction parameter, that is, the number of related instructions can be different, and the corresponding number of historical brightness can also be different.

[0070] S420: Multiply the difference between the sum and the specified historical brightness by a second constant to obtain a current brightness correction value.

[0071] S430: performing a sum operation on the current brightness correction value and the specified historical brightness to obtain the current target brightness displayed on the screen.

[0072] S410 to S430 are exemplarily described, and the current target brightness is calculated according to the following formula:

[0073] Q(S,A)'=Q(S,A)+α[R+γQ(S',A')-Q(S,A)];

[0074] Among them, Q(S, A)' represents the current target brightness, Q(S, A) represents the specified historical brightness, α represents the second constant, R represents the adjustment correction parameter, γ represents the first constant, and Q(S', A') represents the current initial brightness; A represents the specific operation: the brightness increase operation is (+), the brightness decrease operation is (-), and the brightness unchanged operation is (0); R is the average value calculated from all historical brightness in the historical brightness increase / decrease instructions within one month before the current moment.

[0075] In another exemplary embodiment of the present application, correction is also made for the relevant historical brightness. The relationship between the historical light intensity parameter and the historical brightness is exemplarily described below:

[0076] Without considering the brightness adjustment command (i.e., without considering the influence of the user's autonomous brightness adjustment factor), the original relationship diagram without correction is as follows: Figure 5 As shown, on this basis, the brightness adjustment instruction is introduced, and the relationship diagram obtained is as follows Figure 6 This application uses the window average algorithm to Figure 6 The relationship curve shown in the figure is smoothed to obtain Figure 7 The relationship diagram shown in FIG. 1 is a diagram in which three adjacent points are smoothed to obtain exemplary data shown in Table 1, so as to reduce the influence of accidental errors of individual historical brightness on the accuracy of target brightness. The exemplary process of smoothing is as follows:

[0077]

[0078] Among them, MA1′ represents the first historical brightness after correction, MA2′ represents the second historical brightness after correction, and MA n ′ represents the corrected nth historical brightness, MA1 represents the first historical brightness, MA2 represents the second historical brightness, MA3 represents the third historical brightness, MA4 represents the fourth historical brightness, MA n Indicates the nth historical brightness, MA n+1 Indicates the (n+1)th historical brightness, MA n Indicates the (n+2)th historical brightness.

[0081] In another exemplary embodiment of the present application, the application scenarios of the above-mentioned multiple determination methods are exemplarily described.
