Therefore, the screen brightness of each screen can be determined by only collecting the initial ambient light brightness data at the reference point position, combining the ambient light influencing factor corresponding to each screen, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. In other words, by installing only one ambient light source detection device to collect ambient light brightness data, the differences between the ambient light brightness data of screens at different locations and the reference point location are considered. At the same time, the influence of ambient light brightness factors on the ambient light brightness of each screen is combined to determine the target ambient light brightness data of each screen. Then, based on the target ambient light brightness data, the screen brightness of each screen is adaptively adjusted. This reduces costs while improving the accuracy of screen brightness determination for each screen, and also meets the user's viewing needs, thus improving the user experience.

[0037] In typical scenarios with multiple screens in a vehicle cabin, to reduce costs, only one ambient light source detection device is usually installed to collect ambient light brightness data. The brightness of each screen is adjusted based on this data. However, due to cabin layout limitations, the ambient light brightness varies significantly between front and rear passengers, leading to different screen brightness requirements. This results in inaccurate brightness adjustment and an inability to meet user needs. In some vehicles, the screen corresponding to the ambient light source detection device is adaptively adjusted based on the collected ambient light brightness data, while other screens require manual brightness adjustment by the user. This reduces the intelligence of screen brightness adjustment and the user experience. Therefore, how to accurately and effectively adaptively adjust the brightness of each screen while reducing costs is a pressing technical problem. To address this issue, this disclosure provides a screen brightness determination method, which is described below with reference to specific embodiments.
[0038] Figure 1 This is a flowchart of a screen brightness determination method provided in an embodiment of the present disclosure. The method can be executed by a screen brightness determination device, which can be implemented in software and / or hardware. The screen brightness determination device can be configured in an electronic device, such as a server or terminal, wherein the terminal specifically includes an in-vehicle terminal, a computer, or a tablet computer, etc.
[0039] like Figure 1 As shown, the screen brightness determination method provided in this embodiment can be applied to determining the screen brightness in a vehicle cabin, and can also be applied to adjusting the screen brightness in other application scenarios, without limitation. The screen brightness determination method may include the following steps.
[0040] S110. Obtain the initial ambient light brightness data of the vehicle, at least one ambient light brightness influencing factor corresponding to the vehicle, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. The initial ambient light brightness data is the ambient light brightness data corresponding to the reference point position of the vehicle.
[0041] In this embodiment of the disclosure, the screen brightness determination method is applicable to application scenarios where an ambient light source detection device is installed in the cockpit, but multiple screens require adaptive adjustment of screen brightness.
[0042] In this embodiment of the disclosure, the ambient light brightness data can be the ambient light brightness value.
[0043] The initial ambient light intensity data is the ambient light intensity data corresponding to the vehicle's reference point location. The reference point location can be understood as the location of the ambient light source detection device within the vehicle used to collect the initial ambient light intensity data. For example, the reference point location could be the location of an ambient light source detection device installed inside the vehicle's cabin to collect ambient light intensity data from the central control screen. For example, the reference point location could be as follows: Figure 2 The location of point A shown.
[0044] In this embodiment of the disclosure, ambient light brightness influencing factors can be understood as factors that affect the ambient light brightness of the screen. These factors can vary depending on the vehicle model. For example, ambient light brightness influencing factors may include sunroof, windows, reading lights, etc.
[0045] In this embodiment of the disclosure, the linear variation coefficient can be understood as a coefficient used to characterize the linear relationship between the initial ambient light brightness data and the ambient light brightness data of each screen.
[0046] In this embodiment of the disclosure, the linear variation coefficient corresponding to the screen varies with the screen position and / or the vehicle model. For example, within the same vehicle cabin, the linear variation coefficient corresponding to the screen in different positions may be different; the linear variation coefficient corresponding to the screen in the same position may also be different for different vehicle models.
[0047] Specifically, in response to the vehicle's infotainment system being turned on or upon receiving a screen brightness adjustment command, the electronic device can control the in-vehicle ambient light detection device to collect ambient light data, thus obtaining initial ambient light data. Simultaneously, it acquires basic vehicle information, and based on this information, obtains at least one ambient light influencing factor corresponding to the vehicle, as well as the linear variation coefficient between the initial ambient light data and the ambient light data for each screen.
[0048] S120. For each screen, determine the ambient light compensation value of at least one ambient light brightness influencing factor on the screen; based on the initial ambient light brightness data, the linear variation coefficient and the ambient light brightness compensation value, determine the target ambient light brightness data corresponding to the screen.
[0049] In this embodiment of the disclosure, determining the ambient light compensation value of the screen due to at least one ambient light brightness influencing factor may include: determining the state information corresponding to the at least one ambient light brightness influencing factor, and determining the ambient light compensation value based on the state information. For example, the state information may include being in an on state, being in a off state, etc.
[0050] Different status information has different effects on the ambient light brightness of the screen. For example, the effect on the ambient light brightness of the screen is different when the sunroof is open and when the sunroof is closed.
[0051] Specifically, after acquiring the initial ambient light brightness data, at least one ambient light brightness influencing factor corresponding to the vehicle, and the linear variation coefficient, the electronic device determines the ambient light brightness compensation value of at least one ambient light brightness influencing factor for each screen based on the state information corresponding to each ambient light brightness influencing factor. At the same time, it calculates the ambient light brightness data of each screen based on the linear variation coefficient and the initial ambient light brightness data, and on this basis, combined with the ambient light brightness compensation value, obtains the target ambient light brightness data corresponding to each screen.
[0052] S130. Determine the screen brightness based on the target ambient light brightness data.
[0053] In this embodiment of the disclosure, after the electronic device obtains the target ambient light brightness data corresponding to each screen, it obtains the preset correspondence between the ambient light brightness data and the screen brightness, determines the target screen brightness corresponding to the target ambient light brightness data of each screen based on the correspondence, determines the target screen brightness as the screen brightness corresponding to the screen, and adaptively adjusts the brightness of the screen based on the screen brightness.
[0054] In this embodiment, the system can acquire the vehicle's initial ambient light brightness data, at least one ambient light brightness influencing factor corresponding to the vehicle, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. The initial ambient light brightness data is the ambient light brightness data corresponding to the vehicle's reference point position. For each screen, at least one ambient light brightness influencing factor is used to determine the screen's ambient light brightness compensation value. Based on the initial ambient light brightness data, the linear variation coefficient, and the ambient light brightness compensation value, the target ambient light brightness data corresponding to the screen is determined. After acquiring the target ambient light brightness data, the screen brightness is determined based on the target ambient light brightness data. Therefore, the screen brightness of each screen can be determined by only collecting the initial ambient light brightness data at the reference point position, combining the ambient light influencing factor corresponding to each screen, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. In other words, by installing only one ambient light source detection device to collect ambient light brightness data, the differences between the ambient light brightness data of screens at different locations and the reference point location are considered. At the same time, the influence of ambient light brightness factors on the ambient light brightness of each screen is combined to determine the target ambient light brightness data of each screen. Then, based on the target ambient light brightness data, the screen brightness of each screen is adaptively adjusted. This reduces costs while improving the accuracy of screen brightness determination for each screen, and also meets the user's viewing needs, thus improving the user experience.
[0055] Based on the above embodiments of this disclosure, the screen brightness determination method can also avoid the problem of determining the screen brightness based on the brightness change data of the user's face by collecting the user's facial image, and then adaptively adjusting the screen brightness. It is not restricted by user authorization and improves the flexibility of screen brightness adjustment.
[0056] In this embodiment of the disclosure, the electronic device can obtain at least one ambient light brightness influencing factor corresponding to the vehicle from a preset database based on the vehicle's basic information, as well as the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. Thus, for the same vehicle model, only the ambient light brightness influencing factor and the linear variation coefficient need to be determined once, and it can be used on multiple vehicles belonging to the same vehicle model, thereby improving the accuracy and efficiency of determining the ambient light brightness influencing factor and the linear variation coefficient.
[0057] Specifically, obtaining at least one ambient light brightness influencing factor corresponding to the vehicle, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen, may include: obtaining basic information about the vehicle, including at least one of the vehicle's identification information and model information; and obtaining at least one ambient light brightness influencing factor and linear variation coefficient based on the vehicle's basic information.
[0058] Among them, the identification information corresponding to the vehicle can be the vehicle's unique identifier.
[0059] Vehicle model information can be information related to the type and configuration of the vehicle. For example, vehicle model information may include sedan, sport utility vehicle (SUV), high-end configuration, mid-range configuration, etc.
[0060] In some embodiments of this disclosure, the electronic device can search for at least one ambient light brightness influencing factor corresponding to the identification information of the vehicle from a preset database, as well as the linear change coefficient corresponding to each screen, thereby obtaining at least one ambient light brightness influencing factor and linear change coefficient corresponding to the vehicle.
[0061] In other embodiments of this disclosure, the electronic device can search a preset database for ambient light brightness influencing factors that match the vehicle model information, as well as the linear variation coefficient corresponding to each screen, based on the vehicle model information, thereby obtaining at least one ambient light brightness influencing factor and linear variation coefficient corresponding to the vehicle.
[0062] In this embodiment of the disclosure, the linear variation coefficient can be directly obtained based on the different vehicle models or identification information corresponding to the vehicle. This eliminates the need to recalculate the linear variation coefficient and determine the factors affecting ambient light brightness each time the ambient light brightness is calculated, thus avoiding the problem of installing multiple ambient light detection devices. At the same time, it also improves the accuracy and efficiency of determining the linear variation coefficient and the factors affecting ambient light brightness.
[0063] The method for determining the linear variation coefficient is described in detail below.
[0064] Figure 3 This is a flowchart of a method for determining linear variation coefficients provided in an embodiment of this disclosure, as follows: Figure 3 As shown, the method for determining the linear variation coefficient may include the following steps: S310: Obtain the first ambient light brightness data of the vehicle at the reference point position, and the second ambient light brightness data corresponding to each screen.
[0065] In this embodiment of the disclosure, the second ambient light brightness data can be obtained by collecting ambient light brightness data from the target ambient light detection device corresponding to each screen. The second ambient light brightness data may include multiple ambient light brightness values for each screen at different times. For example, ambient light brightness values at different times during the day, ambient light brightness values at different times at night, etc.
[0066] In this embodiment of the disclosure, the first ambient light brightness data and the second ambient light brightness data can be ambient light brightness data corresponding to different locations that have been pre-collected and stored in a preset database. The first ambient light brightness data and the second ambient light brightness data can be understood as ambient light brightness data from different locations collected synchronously.
[0067] For example, such as Figure 2 As shown, point A is the reference point, such as the position of the central control screen; point B is the position corresponding to any screen lock in the rear row. The first ambient light brightness data consists of multiple ambient light brightness data points corresponding to point A at different times, denoted as A1, A2, ..., An; the second ambient light brightness data consists of multiple ambient light brightness data points corresponding to point B at different times, denoted as B1, B2, ..., Bn. The number of 'n' can be a positive integer greater than a preset value. For example, 'n' is a positive integer greater than 30.
[0068] Specifically, the electronic device can obtain the first ambient light brightness data of the vehicle at the reference point location and the second ambient light brightness data corresponding to each screen from a preset database based on the vehicle's basic information.
[0069] S320. For each ambient light intensity influencing factor, obtain the third ambient light intensity data and initial weight corresponding to the ambient light intensity influencing factor.
[0070] In this embodiment of the disclosure, the third ambient light brightness data can be understood as the ambient light brightness data collected by the target ambient light detection device corresponding to each screen, based on the influence of each ambient light brightness influencing factor on each screen.
[0071] In this embodiment of the disclosure, the third ambient light brightness data may be ambient light brightness data corresponding to different locations that have been pre-collected and stored in a preset database. The third ambient light brightness data can be understood as being collected synchronously with the first ambient light brightness data and the second ambient light brightness data.
[0072] In this embodiment of the disclosure, the initial weight can be a pre-set weight corresponding to each environmental influencing factor, or it can be a weight corresponding to each environmental influencing factor calculated based on the third ambient light brightness data and a preset weighting algorithm, and there is no limitation on this.
[0073] Furthermore, the electronic device can obtain the third ambient light luminance data corresponding to each ambient light luminance influencing factor from a preset database based on the vehicle's basic information.
[0074] For example, the influence of ambient light levels on factors including skylights and reading lights will be used as examples for illustration. Figure 2 As shown, the third ambient light brightness data can include multiple ambient light brightness data at different times corresponding to point B when the sunroof is open, denoted as B1a, B2a, ..., Bna respectively; and multiple ambient light brightness data at different times corresponding to point B when the reading light is on, denoted as B1b, B2b, ..., Bnb respectively.
[0075] S330. Based on the initial weights, the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data, determine the linear variation coefficient corresponding to the ambient light brightness data of each screen.
[0076] In this embodiment of the disclosure, after the electronic device obtains the initial weight, the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data, for each screen, it calculates the difference between the second ambient light brightness value corresponding to the second ambient light brightness data and the first ambient light brightness value corresponding to the first ambient light brightness data to obtain a first value; it calculates the sum of the products of the initial weight corresponding to each ambient light brightness influencing factor and its corresponding third ambient light brightness data to obtain a second value, and determines the ratio of the first value to the second value as the linear change coefficient corresponding to the screen.
[0077] For example, such as Figure 2 As shown, taking the screen corresponding to point B as an example, the formula for calculating the linear variation coefficient of this screen is as follows: K=(B1-A1) / (β1×B1a+β2×B2a).
[0078] Where K is the linear variation coefficient; β1 and β2 are the weights of the skylight and reading light, which are the influencing factors of ambient light brightness, respectively.
[0079] After calculating the target linear change coefficient for each set of ambient light brightness data, the electronic device can sum and average the target linear change coefficients corresponding to multiple sets of ambient light brightness data to obtain the linear change coefficient corresponding to the screen.
[0080] In this embodiment of the disclosure, the linear variation coefficient can be determined by using the ambient light brightness data of the reference point location, the ambient light brightness data corresponding to each screen, and the ambient light brightness data corresponding to each screen after being affected by ambient light brightness factors, thereby improving the accuracy of determining the linear variation coefficient.
[0081] In this embodiment of the disclosure, in order to improve the accuracy of ambient light brightness data, the electronic device can preprocess the first ambient light brightness data, the second ambient light brightness data and the third ambient light brightness data after acquiring them.
[0082] Specifically, after obtaining the third ambient light brightness data corresponding to the factors affecting ambient light brightness, the screen brightness determination method may further include: preprocessing the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data to obtain preprocessed first ambient light brightness data, preprocessed second ambient light brightness data, and preprocessed third ambient light brightness data; wherein, the preprocessing includes outlier removal processing.
[0083] In this embodiment of the disclosure, after acquiring the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data, the electronic device can calculate the mean and standard deviation corresponding to the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data, respectively. Based on the mean and standard deviation, it can determine whether there is abnormal ambient light brightness data. When it is determined that there is abnormal ambient light brightness data, it can be removed to avoid interference and influence of invalid data on the calculation of the linear change coefficient.
[0084] For example, we will use multiple ambient light brightness data B1a, B2a, ..., Bna at different times corresponding to point B as examples for illustration.
[0085] Calculate the mean (μ) and standard deviation (σ) of B1a, B2a, ..., Bna, identify the values of B1a, B2a, ..., Bna that exceed the range of [μ-3σ, μ+3σ], determine them as abnormal ambient light brightness data, and remove them.
[0086] In this embodiment of the disclosure, outlier removal processing can be performed on ambient light intensity data collected at different locations or under different conditions, thereby ensuring the validity and accuracy of the processed ambient light intensity data and improving the accuracy of determining the linear variation coefficient.
[0087] In this embodiment of the disclosure, the electronic device can also verify the initial weights corresponding to each ambient light brightness influencing factor to determine their effectiveness.
[0088] Specifically, after obtaining the initial weights corresponding to the factors affecting ambient light brightness, the screen brightness determination method may further include: determining the predicted ambient light brightness data for each screen based on the initial weights and the third ambient light brightness data; calculating the difference between the predicted ambient light brightness data and the second ambient light brightness data for each screen; and verifying the initial weights based on the difference and a preset difference threshold.
[0089] In this embodiment of the disclosure, the specific calculation formula for predicting ambient light intensity data is as follows: P = β0 + β1 × M + β2 × N.
[0090] Where P is the predicted ambient light intensity data, i.e., the predicted ambient light intensity value; β0 is a preset constant; M and N are the ambient light intensity data corresponding to different ambient light intensity influencing factors.
[0091] For example, β1 and β2 are the weights of the sunroof and reading light, which are the influencing factors of ambient light intensity, respectively. M can be any third ambient light intensity data corresponding to the sunroof when it is open, or it can be the average of any number of third ambient light intensity data corresponding to the sunroof when it is open. The determination of N is similar to that of M, and will not be elaborated here.
[0092] Furthermore, after determining the difference, the electronic device compares the difference with a preset difference threshold. If the difference is greater than the preset difference threshold, the initial weight verification is determined to be unsuccessful; if the difference is less than or equal to the preset difference threshold, the initial weight verification is determined to be successful.
[0093] In this embodiment of the disclosure, the linear change coefficient corresponding to the ambient light brightness data of each screen is determined based on the initial weight, the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data. Specifically, this may include: if the initial weight verification passes, determining the linear change coefficient corresponding to the ambient light brightness data of each screen based on the initial weight, the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data; if the initial weight verification fails, adjusting the initial weight, and determining the linear change coefficient corresponding to the ambient light brightness data of each screen based on the adjusted target weight, the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data.
[0094] In this embodiment of the disclosure, adjusting the initial weight can be understood as reducing the initial weight. Specifically, the electronic device can adjust the initial weight based on a preset adjustment rule.
[0095] In this embodiment of the disclosure, by verifying the initial weights corresponding to each ambient light intensity data, the accuracy of the weights corresponding to each ambient light intensity data is improved, thereby improving the accuracy of determining the linear change coefficient.
[0096] In this embodiment of the disclosure, before determining the ambient light brightness compensation value of the screen for at least one ambient light brightness influencing factor; and before determining the target ambient light brightness data corresponding to the screen based on the initial ambient light brightness data, the linear variation coefficient, and the ambient light brightness compensation value, the screen brightness determination method may further include: acquiring state information corresponding to each ambient light brightness influencing factor; and determining the weight corresponding to each ambient light brightness influencing factor based on the state information.
[0097] For example, when the ambient light brightness influencing factor is the skylight, if the skylight is in the open state, it means that the ambient light brightness influencing factor of the skylight has an impact on the screen brightness. In this case, the initial weight or the adjusted target weight corresponding to the skylight is determined as its corresponding weight for subsequent calculation of target ambient light brightness data. If the skylight is in the closed state, it means that the ambient light brightness influencing factor of the skylight has no impact on the screen brightness. In this case, its corresponding weight is determined to be zero.
[0098] Furthermore, determine the ambient light compensation value for the screen based on at least one ambient light brightness influencing factor; determine the target ambient light brightness data corresponding to the screen based on the initial ambient light brightness data, the linear variation coefficient, and the ambient light brightness compensation value, which may specifically include: calculating the ambient light brightness compensation value based on the weight corresponding to each ambient light brightness influencing factor; calculating the product of the linear variation coefficient and the initial ambient light brightness data, and determining the target ambient light brightness data corresponding to the screen based on the product and the ambient light brightness compensation value.
[0099] Specifically, the electronic device determines the sum of the weights corresponding to each ambient light brightness influencing factor as the ambient light brightness compensation value, and determines the sum of the product of the linear change coefficient and the initial ambient light brightness data and the ambient light brightness compensation value as the target ambient light brightness data corresponding to the screen, i.e., the target ambient light brightness value.
[0100] In this embodiment of the disclosure, the weight of each ambient light brightness influencing factor can be determined according to its state, and then the ambient light brightness compensation value can be calculated. That is, the ambient light brightness compensation value corresponding to each screen can be determined by combining the actual state information of the vehicle, which improves the accuracy and flexibility of determining the target ambient light brightness data corresponding to each screen.
[0101] Figure 4 This is a flowchart of another screen brightness determination method provided in this disclosure embodiment; as follows: Figure 4 As shown, the screen brightness determination method may include the following steps: S410: Obtain the initial ambient light brightness data of the vehicle, at least one ambient light brightness influencing factor corresponding to the vehicle, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen.
[0102] S420. Obtain the state information corresponding to each ambient light intensity influencing factor; determine the weight corresponding to each ambient light intensity influencing factor based on the state information.
[0103] S430. Calculate the ambient light compensation value based on the weight corresponding to each ambient light brightness influencing factor.
[0104] S440. Calculate the product of the linear variation coefficient and the initial ambient light brightness data. Based on the product and the ambient light brightness compensation value, determine the target ambient light brightness data corresponding to the screen.
[0105] S450: Determine the screen brightness based on the target ambient light brightness data.
[0106] It should be noted that the specific implementation methods of steps S410 to S450 are similar to those of the relevant steps in the above embodiments of this disclosure, and will not be repeated here.
[0107] In this embodiment, the screen brightness of each screen can be determined by collecting only the initial ambient light brightness data at the reference point location, combining the ambient light influencing factors for each screen, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. In other words, by installing only one ambient light source detection device to collect ambient light brightness data, the differences between the ambient light brightness data of screens at different locations and the reference point location are considered. Simultaneously, the influence of ambient light brightness influencing factors on the ambient light brightness of each screen and the state information of each ambient light brightness influencing factor are combined to determine the target ambient light brightness data for each screen. Then, based on the target ambient light brightness data, the screen brightness of each screen is adaptively adjusted. This reduces costs while improving the accuracy of screen brightness determination for each screen, meeting user viewing needs and enhancing the user experience.
[0108] Figure 5 This is a schematic diagram of the structure of a screen brightness determination device provided in an embodiment of this disclosure.
[0109] In this embodiment, the screen brightness determination device can be located within an electronic device and is understood as a functional module within the aforementioned electronic device. Specifically, the electronic device can be a server or a terminal, wherein the terminal specifically includes an in-vehicle terminal, a computer, or a tablet computer, etc., and is not limited thereto.
[0110] like Figure 5 As shown, the screen brightness determination device 500 may include an information acquisition module 510, an ambient light brightness determination module 520, and a screen brightness determination module 530.
[0111] The information acquisition module 510 can be used to acquire the initial ambient light brightness data of the vehicle, at least one ambient light brightness influencing factor corresponding to the vehicle, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. The initial ambient light brightness data is the ambient light brightness data corresponding to the reference point position of the vehicle. The ambient light brightness determination module 520 can be used to determine the ambient light brightness compensation value of the screen for at least one ambient light brightness influencing factor; and to determine the target ambient light brightness data corresponding to the screen based on the initial ambient light brightness data, the linear change coefficient and the ambient light brightness compensation value. The screen brightness determination module 530 can be used to determine the screen brightness based on target ambient light brightness data.
[0112] In this embodiment, the system can acquire the vehicle's initial ambient light brightness data, at least one ambient light brightness influencing factor corresponding to the vehicle, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. The initial ambient light brightness data is the ambient light brightness data corresponding to the vehicle's reference point position. For each screen, at least one ambient light brightness influencing factor is used to determine the screen's ambient light brightness compensation value. Based on the initial ambient light brightness data, the linear variation coefficient, and the ambient light brightness compensation value, the target ambient light brightness data corresponding to the screen is determined. After acquiring the target ambient light brightness data, the screen brightness is determined based on the target ambient light brightness data. Therefore, the screen brightness of each screen can be determined by only collecting the initial ambient light brightness data at the reference point position, combining the ambient light influencing factor corresponding to each screen, and the linear variation coefficient between the initial ambient light brightness data and the ambient light brightness data of each screen. In other words, by installing only one ambient light source detection device to collect ambient light brightness data, the differences between the ambient light brightness data of screens at different locations and the reference point location are considered. At the same time, the influence of ambient light brightness factors on the ambient light brightness of each screen is combined to determine the target ambient light brightness data of each screen. Then, based on the target ambient light brightness data, the screen brightness of each screen is adaptively adjusted. This reduces costs while improving the accuracy of screen brightness determination for each screen, and also meets the user's viewing needs, thus improving the user experience.

[0116] In some embodiments of this disclosure, the screen brightness determination device 500 may further include a data preprocessing module.
[0117] The data preprocessing module can be used to preprocess the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data after obtaining the third ambient light brightness data corresponding to the factors affecting ambient light brightness, so as to obtain the preprocessed first ambient light brightness data, the preprocessed second ambient light brightness data, and the preprocessed third ambient light brightness data; wherein, the preprocessing includes outlier removal processing.
[0118] In some embodiments of this disclosure, the screen brightness determination device 500 may further include a weight verification module.
[0119] The weight verification module can be used to determine the predicted ambient light brightness data for each screen based on the initial weights and the third ambient light brightness data after obtaining the initial weights corresponding to the factors affecting ambient light brightness. Calculate the difference between the predicted ambient light brightness data and the second ambient light brightness data corresponding to each screen; The initial weights are validated based on the difference and a preset difference threshold.
[0120] The linear variation coefficient determination unit can be specifically used to determine the linear variation coefficient corresponding to the ambient light brightness data of each screen based on the initial weight, the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data, provided that the initial weight verification is passed. If the initial weight verification fails, the initial weight is adjusted, and the linear change coefficient corresponding to the ambient light brightness data of each screen is determined based on the adjusted target weight, the first ambient light brightness data, the second ambient light brightness data, and the third ambient light brightness data.
[0121] In some embodiments of this disclosure, the screen brightness determination device 500 may further include a weight determination module.
[0122] The weight determination module can be used to obtain the state information corresponding to each ambient light influencing factor before determining the ambient light compensation value of the screen based on at least one ambient light brightness influencing factor and the target ambient light brightness data corresponding to the screen, based on the initial ambient light brightness data, linear change coefficient and ambient light brightness compensation value. The weight of each factor affecting ambient light intensity is determined based on the state information.
[0123] In some embodiments of this disclosure, the ambient light brightness determination module 520 can be specifically used to calculate the ambient light brightness compensation value based on the weight corresponding to each ambient light brightness influencing factor. Calculate the product of the linear variation coefficient and the initial ambient light brightness data. Based on the product and the ambient light brightness compensation value, determine the target ambient light brightness data corresponding to the screen.
