[0028] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different figures represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0029] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically separate entities. That is, these functional entities may be implemented in software, 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 for illustrative purposes only and do not necessarily include all contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps may be decomposed, while others may be combined or partially combined. Therefore, the actual execution order may vary depending on the actual situation.

[0031] In this application, "plurality" refers to two or more. "And / or" describes the relationship between related objects, indicating that three possible relationships exist. For example, "A and / or B" can mean: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0032] The brightness adjustment algorithm for the display screen of an electronic device is generally based on subjective adjustment based on human will, without considering other factors that affect the screen brightness. As a result, the determined screen brightness is inaccurate, making it unsuitable for relevant scenarios. The screen brightness cannot be accurately adjusted to the brightness that meets user needs, which reduces the user's visual experience.

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

[0034] S110: Determine the current initial brightness based on the brightness adjustment instruction, current screen parameters and 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] A brightness adjustment instruction is an instruction indicating that a user desires to adjust the screen brightness, such as increasing, decreasing, or maintaining the screen brightness. In some embodiments, the brightness adjustment instruction includes the intensity of the brightness adjustment, data for increasing / decreasing the brightness, and may also include a target brightness value to be achieved.

[0036] The current screen parameters are the screen-related parameters at the current moment, which represent 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 parameters related to 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, rather than using adjacent historical brightness levels to determine the current initial brightness, the screen brightness may be the brightness immediately before the brightness adjustment instruction issued by the user is received by the subject of this application. This may be the screen brightness at any of the preceding historical moments. To better meet the user's adjustment expectations, this embodiment determines the current initial brightness based on adjacent historical brightness levels (i.e., the screen brightness at the previous historical moment adjacent to the current moment).

[0039] In some embodiments, the current user's identity information needs to be identified to determine the appropriate adjacent historical brightness and designated historical brightness. For example, the current user's identity information is matched with preset identity information. If the match is successful, the adjacent historical brightness and designated historical brightness are determined from the historical parameters corresponding to the matched preset identity information. If the match fails, the adjacent historical brightness and designated historical brightness are determined from the historical parameters corresponding to the universal identity information. Universal identity information is similar to tourist identity information; there is no need to record or 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 these historical parameters can be more suitable for the current user's operating habits and visual experience, can reduce the adjustment operation and / or adjustment effort 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 in the record and storage, and no relevant historical parameters are recorded. In this case, 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). These two historical parameters do not have personalized identity characteristics and are used as backup historical parameters for the screen brightness determination method 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 for the screen brightness, it indicates that the user desires to adjust the original screen brightness. 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 for a continuous period of one 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., the 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 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. 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 extrinsic 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 and obtain the target brightness suitable for the current scene 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. 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 an adjustment parameter corresponding to the brightness adjustment instruction according to the brightness adjustment instruction representing the operation on the screen brightness; wherein a brightness increase operation corresponds to a positive adjustment parameter, and a brightness decrease operation corresponds to a 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 indicates an increase in screen brightness, the adjustment parameter is determined to be a positive number; otherwise, it is determined to be a negative number. The positive and negative values ​​are used to represent the positive and negative effects of the adjustment parameter on the current initial brightness calculation process. The positive and negative values ​​are merely relative, representing different effects on the current initial brightness and do not represent good or bad.

[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 the numerical values ​​of the relevant parameters, 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 environmental 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 to increase the screen brightness, and the 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 or 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 parameter, the current ambient weather parameter, the current position parameter, and the current time parameter; 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 on 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, this 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. Figure 2 The illustrated S220 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, to obtain 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, this application discovered that different color areas and color block sizes in the display screen will affect the user's visual senses. The higher the reflectivity of the color, the more obvious it is at the visual level, and it will give people a brighter visual experience.

[0060] This embodiment increases the influence of colors with high reflectivity on the numerical parameterization by setting a larger preset weight coefficient for colors with high reflectivity. At the same time, the display area is divided and the area parameters of each display area are combined 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 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. Figure 1 The illustrated S120 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 with 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 instructions.

[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 instructions include historical brightness increase instructions and historical brightness decrease instructions. If the brightness adjustment instruction represents an increase operation on the screen brightness, the adjustment correction parameter is determined based on the historical brightness increase instruction; if the brightness adjustment instruction represents a decrease operation on the screen brightness, the adjustment correction parameter is determined based on the historical brightness decrease instruction; wherein each relevant instruction carries a historical brightness value, and in order to balance the calculation effects between different positive and negative parameters, the number of historical brightness increase instructions and historical brightness decrease instructions is made the same. For example: if the brightness adjustment instruction represents a brightness increase operation, the average value of all historical brightness values ​​(a total of 100) in the 100 historical brightness increase instructions before the current moment is calculated as the adjustment correction parameter. For another example: if the brightness adjustment instruction represents a brightness decrease operation, the average value of all historical brightness values ​​(a total of 100) in the 100 historical brightness decrease instructions before the current moment is calculated 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 calculation parameters of each are selected by limiting the same historical duration. For example, the average value of all historical brightness calculated based on the historical brightness increase / decrease instructions within a 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: Multiplying the difference between the sum value and the specified historical brightness by a second constant to calculate 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] Where 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 the 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 exemplified 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 Table 1 is obtained by smoothing three adjacent points to obtain exemplary data to reduce the impact of accidental errors in individual historical brightness on the accuracy of target brightness. The exemplary smoothing process 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 multiple determination methods are exemplified. For details, please refer to Figure 8 , Figure 8Schematic diagram of an application scenario of the method for determining screen brightness of the present application, wherein the user terminal 100, the interactive screen 200 and the server 300 are connected via wireless communication, and the present application does not limit the connection method between them.

[0082] The user inputs a brightness adjustment instruction to the interactive screen 200 through the user terminal 100, so that the interactive screen 200 is transmitted to the server 300, so that the server 300, as the execution subject, executes the determination method shown in any of the above exemplary embodiments, which is exemplified as follows:

[0083] The server 300 determines the current initial brightness based on 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; if the brightness adjustment instruction represents an increase / decrease operation on the screen brightness, the server 300 determines the current target brightness of the screen display 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.

The server 300 can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network) and big data and artificial intelligence platforms, and this is not restricted here.

[0085] Another aspect of the present application also provides a device for determining screen brightness, such as Figure 9 As shown, Figure 9 1 is a schematic diagram of a device for determining screen brightness according to an exemplary embodiment of the present application. The determination device 900 includes:
