Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of electronic information technology, and in particular, to a screen brightness adjustment method and device, an electronic device, and a storage medium. BACKGROUND

[0002] A light sensor is a kind of light-digital converter, which can collect the intensity of light in the surrounding environment. Therefore, the intensity of ambient light is often obtained by setting a light sensor in a terminal, so as to adjust the screen brightness according to the intensity of ambient light at the current time obtained in real time.

[0003] However, the method for determining light sensing data for adjusting screen brightness by the above-mentioned manner is too single. If the light sensor of the terminal is blocked, or the position of the light source is moved, the light sensing data will fluctuate greatly, so that the light sensing data collected by the light sensor in real time cannot accurately reflect the intensity of the current ambient light, and further affect the adjustment effect of the screen brightness.

[0044] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0045] Figure 1is a flowchart of a screen brightness adjustment method according to an exemplary embodiment, which is applied to a terminal, the terminal comprising at least a first light sensor and a second light sensor, the terminal having a first face and a second face arranged oppositely, the first face being a plane where a screen of the terminal is located, the first light sensor being arranged at the first face, and the second light sensor being arranged at the second face. It can be understood that the first face is a front face of the terminal, and the second face is a back face of the terminal. The terminal can be a mobile terminal such as a smartphone, a tablet computer, a smart television, a smart watch, a PDA (English: Personal Digital Assistant, Chinese: Personal Digital Assistant), a portable computer, etc., or can be a smart home device such as a sweeping robot, an air purifier, an air conditioner, a lighting lamp, a sound box, a robot, etc. The present disclosure does not limit this. Figure 1 As shown in the figure, the method comprises the following steps:

[0046] In step S101, first light sensing data of a current time and first historical light sensing data collected in a preset historical time period are obtained by the first light sensor.

[0047] The data collected by the first light sensor can be stored in a first data array set in advance, and the first data array type can be, for example, a FIFO (English: First Input First Output; Chinese: First Input First Output) array, so as to store a certain amount of data without occupying more storage space. The first historical light sensing data collected in the preset historical time period can be historical data collected by the first light sensor in all historical times stored in the first data array, or historical data collected in a certain historical time period.

[0048] In step S102, second light sensing data of a current time and second historical light sensing data collected in a preset historical time period are obtained by the second light sensor.

[0049] The data collected by the second light sensor can be stored in a second data array set in advance, and the second data array type can be, for example, a FIFO array, so as to store a certain amount of data without occupying more storage space. The second historical light sensing data collected in the preset historical time period can be historical data collected by the second light sensor in all historical times stored in the second data array, or historical data collected in a certain historical time period.

[0050] In step S103, target light sensing data is determined according to the first light sensing data, the second light sensing data, the first historical light sensing data, and the second historical light sensing data.

[0051] The target light sensing data is used for adjusting the screen brightness of the terminal.

[0052] In actual application scenarios, if the second light sensor is blocked, the second light sensing data collected by the second light sensor will be much smaller than the actual data. Therefore, in order to ensure the accuracy of the second light sensing data, in some embodiments, first, whether the second light sensing data jumps or not can be determined according to the second light sensing data and the second historical light sensing data. Then, third light sensing data of the second light sensor can be determined according to the second light sensing data and the second historical light sensing data. Then, the target light sensing data can be determined according to the first light sensing data, the third light sensing data, the first historical light sensing data and the second historical light sensing data.

[0053] In step S104, the screen brightness of the terminal is adjusted according to the target light sensing data.

[0054] Wherein, adjusting the screen brightness of the terminal according to the target light sensing data can refer to the related method in the prior art, which will not be repeated here.

[0055] By using the above method, the target light sensing data used for adjusting the screen brightness can be determined according to the first light sensing data, the second light sensing data, the first historical light sensing data and the second historical light sensing data. In this way, the target light sensing data used for adjusting the screen brightness can be more accurately determined by comparing the current data and the historical data, thereby improving the adjustment effect of the screen brightness and improving the user experience.

[0056] Figure 2 is a flow chart of another screen brightness adjustment method according to an example embodiment, as shown in Figure 2 The step S103 of determining the target light sensing data according to the first light sensing data, the second light sensing data, the first historical light sensing data and the second historical light sensing data can include the following steps:

[0057] In step S1031, third light sensing data is determined according to the second light sensing data and the second historical light sensing data.

[0058] For example, first, whether the second light sensing data jumps or not can be determined according to the second light sensing data and the second historical data. If it is determined that the second light sensing data jumps, it means that the second light sensing data is inaccurate and deviates from the actual data, and the second light sensor may be blocked. Further, the third light sensing data can be determined according to the second historical light sensing data. If it is determined that the second light sensing data does not jump, it means that the second light sensing data is accurate, and the second light sensing data can be used as the third light sensing data at this time.

[0059] Specifically, the determining the third light-sensing data according to the second light-sensing data and the second historical light-sensing data in step S1031 can include the following steps.

[0060] In step S1031a, a first average value of the second historical light-sensing data collected by the second light sensor in the preset historical time period is determined.

[0061] In step S1031b, whether the second light-sensing data jumps is determined according to the second light-sensing data and the first average value.

[0062] In one possible implementation, first, a first difference value between the second light-sensing data and the first average value of the second historical light-sensing data can be determined. Second, in a case where an absolute value of the first difference value is greater than or equal to a first preset difference threshold, it is determined that the second light-sensing data jumps; or in a case where the absolute value of the first difference value is less than the first preset difference threshold, it is determined that the second light-sensing data does not jump.

[0063] In another possible implementation, first, a second average value between the second light-sensing data and the first average value of the second historical light-sensing data can be determined. Second, a second difference value between the first average value and the second average value is determined. Then, in a case where the second difference value is greater than or equal to a second preset difference threshold, it is determined that the second light-sensing data jumps; or in a case where the second difference value is less than the second preset difference threshold, it is determined that the second light-sensing data does not jump.

[0064] In step S1031c, in a case where it is determined that the second light-sensing data jumps, the first average value is taken as the third light-sensing data.

[0065] In this step, in a case where it is determined that the second light-sensing data jumps, it is indicated that the second light-sensing data is inaccurate and cannot accurately reflect the intensity of the current ambient light. The case can be caused by the second light sensor being blocked, that is, the intensity of the ambient light actually can not have a large change. Therefore, in this embodiment, in a case where it is determined that the second light-sensing data jumps, the first average value of the second historical light-sensing data can be taken as the third light-sensing data.

[0066] In addition, in a case where it is determined that the second light-sensing data does not jump, the second light-sensing data can be taken as the third light-sensing data.

[0067] In a case where it is determined that the second light-sensing data does not jump, it is indicated that the second light-sensing data is accurate and can accurately reflect the intensity of the current ambient light. Therefore, in this embodiment, in a case where it is determined that the second light-sensing data does not jump, the second light-sensing data can be taken as the third light-sensing data.

[0068] In step S1032, the target light sensing data is determined according to the first light sensing data, the third light sensing data, the first historical light sensing data and the second historical light sensing data.

[0069] Specifically, step S1032 can include the following steps:

[0070] In step S1032a, a first ratio of the first light sensing data and the third light sensing data is determined.

[0071] Wherein, the relative position of the external light source relative to the terminal at the current moment is determined according to the first ratio.

[0072] For example, the first ratio can be represented as m = front_als / back_als. Wherein, m represents the first ratio, front_als represents the first light sensing data, and back_als represents the third light sensing data.

[0073] For example, in the case that the first ratio is within a preset ratio range, it can be determined that the external light source at the current moment is located at a first side, which is a side close to a third face of the terminal. The third face is a plane in the terminal perpendicular to the first face and the second face, and can also be understood as a plane in which the middle frame of the terminal is located. In other words, if the first ratio is within the preset ratio range, it can be determined that the external light source at the current moment is located at the side of the terminal. In the case that the first ratio is greater than the maximum value in the preset ratio range, it can be determined that the external light source at the current moment is located at a second side, which is a side close to the first face of the terminal. That is, if the first ratio is greater than the maximum value in the preset ratio range, it can be determined that the external light source at the current moment is located at the front end of the terminal. In the case that the first ratio is less than the minimum value in the preset ratio range, it can be determined that the external light source at the current moment is located at a third side, which is a side close to the second face of the terminal. That is, if the first ratio is less than the minimum value in the preset ratio range, it can be determined that the external light source at the current moment is located at the rear end of the terminal.

[0074] It should be noted that if the first ratio is equal to the maximum value in the preset ratio range or the first ratio is equal to the minimum value in the preset ratio range, it can be determined that the first ratio is within the preset ratio range, that is, the external light source at the current moment is located at the first side.

[0075] In step S1032b, the target light sensing data is determined according to the first ratio, the first light sensing data, the third light sensing data, the first historical light sensing data and the second historical light sensing data.

[0076] Specifically, it can be known from the above analysis that there are three possible cases for the first ratio, such as the first ratio being in a preset ratio range, the first ratio being greater than a maximum value in the preset ratio range, and the first ratio being less than a minimum value in the preset ratio range. Therefore, determining the target light sensing data according to the first ratio, the first light sensing data, the third light sensing data, the first historical light sensing data, and the second historical light sensing data can include the following three possible implementation manners.

[0077] In a first possible implementation manner, in a case where the first ratio is in the preset ratio range, it can be determined that the external light source is located at the first side at this time. Further, determining the target light sensing data according to the first ratio, the first light sensing data, the third light sensing data, the first historical light sensing data, and the second historical light sensing data in the step S1032b can be implemented in the following manner.

[0078] First, a first change trend of data collected by the first light sensor is determined according to the first light sensing data and the first historical light sensing data. Second, a second change trend of data collected by the second light sensor is determined according to the third light sensing data and the second historical light sensing data. Then, the target light sensing data is determined according to the first change trend and the second change trend.

[0079] The first change trend is used to represent a change amplitude and a change rule of the data collected by the first light sensor, and the second change trend is used to represent a change amplitude and a change rule of the data collected by the second light sensor.

[0080] Specifically, determining the target light sensing data according to the first change trend and the second change trend can include: in a case where the first change trend represents that a change amplitude of the data collected by the first light sensor is less than or equal to a first preset change amplitude threshold, and the second change trend represents that a change amplitude of the data collected by the second light sensor is less than or equal to a second preset change amplitude threshold, obtaining third historical light sensing data used by the terminal to adjust the screen brightness at a latest time, and taking the third historical light sensing data as the target light sensing data.

[0081] In other words, in the case that the first change trend indicates that the change amplitude of the data collected by the first light sensor is less than or equal to the first preset change amplitude threshold, it indicates that the data collected by the first light sensor is slowly increasing or slowly decreasing. Similarly, in the case that the second change trend indicates that the change amplitude of the data collected by the second light sensor is less than or equal to the second preset change amplitude threshold, it indicates that the data collected by the second light sensor is slowly increasing or slowly decreasing. If the above two conditions are met simultaneously, it can be determined that the illumination intensity of the external light source is unchanged in a period of time, and at this time, the third historical light sensing data used by the terminal for adjusting the screen brightness last time can be taken as the target light sensing data.

[0082] In addition, in the case that the first change trend indicates that the change amplitude of the data collected by the first light sensor is greater than the first preset change amplitude threshold, and / or the second change trend indicates that the change amplitude of the data collected by the second light sensor is greater than the second preset change amplitude threshold, the maximum value of the first light sensing data and the third light sensing data can be taken as the target light sensing data.

[0083] That is, in the case that the first change trend indicates that the change amplitude of the data collected by the first light sensor is greater than the first preset change amplitude threshold, it indicates that the change amplitude of the data collected by the second light sensor is greater than the second preset change amplitude threshold, and it indicates that the data collected by the second light sensor is not slowly increasing or not slowly decreasing. If at least one of the above conditions is met, it is considered that the illumination intensity of the current external light source has changed. At this time, in order to ensure the accuracy of the target light sensing data, the maximum value of the first light sensing data and the third light sensing data can be taken as the target light sensing data.

[0084] In the second possible implementation, in the case that the first ratio is greater than the maximum value in the preset ratio range, it can be determined that the external light source is located at the second side at this time. Further, the step S1032b of determining the target light sensing data according to the first ratio, the first light sensing data, the third light sensing data, the first historical light sensing data and the second historical light sensing data can be implemented in the following manner:

[0085] Firstly, the first change trend of the data collected by the first light sensor is determined according to the first light sensing data and the first historical light sensing data. Secondly, the first ratio of the first light sensing data and the third light sensing data and the second ratio of the first historical light sensing data and the second historical light sensing data are determined. Then, the third change trend of the ratio between the data collected by the first light sensor and the data collected by the second light sensor is determined according to the first ratio and the second ratio. Finally, the target light sensing data is determined according to the first change trend and the third change trend.

[0086] The third change trend is used to represent a change range and a change rule of a ratio between the data collected by the first light sensor and the data collected by the second light sensor.

[0087] Specifically, according to the first change trend and the third change trend, the target light sensing data can be determined as follows: in a case where the first change trend and the third change trend are the same, third historical light sensing data used by the terminal to adjust screen brightness at a latest time is obtained, and the third historical light sensing data is taken as the target light sensing data.

[0088] If the first change trend and the third change trend are the same, it indicates that the data collected by the first light sensor and the ratio between the data collected by the first light sensor and the data collected by the second light sensor change synchronously, that is, decrease simultaneously or increase simultaneously. If the above condition is met, it can be determined that the external light source moves towards the plane where the terminal is located or moves in a plane perpendicular to the plane where the terminal is located, that is, the illumination intensity of the external light source itself does not change. At this time, the third historical light sensing data used by the terminal to adjust screen brightness at a latest time can be taken as the target light sensing data.

[0089] In addition, in a case where the first change trend and the third change trend are different, a maximum value of the first light sensing data and the third light sensing data can be taken as the target light sensing data.

[0090] That is, in a case where the first change trend and the third change trend are different, it indicates that the data collected by the first light sensor and the ratio between the data collected by the first light sensor and the data collected by the second light sensor do not change synchronously, that is, one decreases and the other increases. If the above condition is met, it can be determined that the illumination intensity of the external light source changes. At this time, a maximum value of the first light sensing data and the third light sensing data can be taken as the target light sensing data.

[0091] In a third possible implementation, in a case where the first ratio is less than a minimum value in a preset ratio range, it can be determined that the terminal is located at the third side at this time. Further, the step S1032b of determining the target light sensing data according to the first ratio, the first light sensing data, the third light sensing data, the first historical light sensing data and the second historical light sensing data can be implemented as follows:

[0092] Firstly, a second change trend of the data collected by the second light sensor is determined according to the third light sensing data and the second historical light sensing data. Secondly, a first ratio of the first light sensing data and the third light sensing data and a second ratio of the first historical light sensing data and the second historical light sensing data are determined. Then, a third change trend of the ratio between the data collected by the first light sensor and the data collected by the second light sensor is determined according to the first ratio and the second ratio. Finally, the target light sensing data is determined according to the second change trend and the third change trend.

[0093] Specifically, the target light sensing data can be determined according to the second change trend and the third change trend, including: in the case that the second change trend and the third change trend are the same, obtaining third historical light sensing data used by the terminal to adjust the screen brightness last time, and taking the third historical light sensing data as the target light sensing data.

[0094] If the second change trend and the third change trend are the same, it indicates that the data collected by the second light sensor and the ratio between the data collected by the first light sensor and the data collected by the second light sensor change synchronously, that is, decrease simultaneously or increase simultaneously. If the above condition is met, it can be determined that the external light source moves towards the plane where the terminal is located or moves in the plane perpendicular to the plane where the terminal is located, that is, the illumination intensity of the external light source itself does not change. At this time, the third historical light sensing data used by the terminal to adjust the screen brightness last time can be taken as the target light sensing data.

[0095] In addition, in the case that the second change trend and the third change trend are not the same, the maximum value of the first light sensing data and the third light sensing data can be taken as the target light sensing data.

[0096] That is, in the case that the second change trend and the third change trend are not the same, it indicates that the data collected by the second light sensor and the ratio between the data collected by the first light sensor and the data collected by the second light sensor do not change synchronously, that is, one decreases and the other increases. If the above condition is met, it can be determined that the illumination intensity of the external light source changes. At this time, the maximum value of the first light sensing data and the third light sensing data can be taken as the target light sensing data.

[0097] By using the above method, the target light sensing data used to adjust the screen brightness can be determined according to the first light sensing data, the second light sensing data, the first historical light sensing data and the second historical light sensing data. In this way, the target light sensing data used to adjust the screen brightness can be more accurately determined by comparing the current data and the historical data, and the adjustment effect of the screen brightness is improved, and the user experience is improved.

[0098] Figure 3 is a flowchart of a screen brightness adjusting method according to an exemplary embodiment, as shown in Figure 3 The method can include the following steps:

[0099] In step S201, the first light sensor acquires the first light data at the current time and the first historical light data in a preset historical time period, and the second light sensor acquires the second light data at the current time and the second historical light data in the preset historical time period.

[0100] In step S202, it is determined whether the second light data jumps according to the second light data and the second historical light data.

[0101] If it is determined that the second light data jumps, step S203 is performed;

[0102] If it is determined that the second light data does not jump, step S204 is performed.

[0103] For example, in a possible implementation, the first average value of the second historical light data collected by the second light sensor in the preset historical time period can be determined first. Then, it is determined whether the second light data jumps according to the second light data and the first average value of the second historical light data. In another possible implementation, the second average value between the first average value of the second light data and the second historical light data can also be determined. Then, it is determined whether the second light data jumps according to the second light data and the second average value. For specific implementation, please refer to the description in step S1031b above, which will not be repeated here.

[0104] In step S203, the first average value of the second historical light data is taken as the third light data.

[0105] In step S204, the second light data is taken as the third light data.

[0106] In step S205, the first ratio of the first light data and the third light data is determined.

[0107] In step S206, it is determined whether the first ratio is within a preset ratio range.

[0108] If it is determined that the first ratio is within the preset range, step S207 is performed;

[0109] If it is determined that the first ratio is outside the preset range, step S208 is performed.

[0110] In step S207, a first change trend of the data collected by the first light sensor and a second change trend of the data collected by the second light sensor are determined.

[0111] In step S208, it is determined whether the first ratio is greater than a maximum value in the preset ratio range.

[0112] In a case where it is determined that the first ratio is greater than the maximum value in the preset ratio range, step S210 is performed.

[0113] In a case where it is determined that the first ratio is not greater than the maximum value in the preset ratio range, step S212 is performed.

[0114] In other words, in a case where it is determined that the first ratio is outside the preset range and it is determined that the first ratio is not greater than the maximum value in the preset ratio range, it is indicated that the first ratio is less than a minimum value in the preset ratio range, and step S212 is performed.

[0115] In step S209, it is determined whether the first change trend indicates that a change amplitude of the data collected by the first light sensor is less than or equal to a first preset change amplitude threshold and whether the second change trend indicates that a change amplitude of the data collected by the second light sensor is less than or equal to a second preset change amplitude threshold.

[0116] In a case where the first change trend indicates that the change amplitude of the data collected by the first light sensor is less than or equal to the first preset change amplitude threshold and the second change trend indicates that the change amplitude of the data collected by the second light sensor is less than or equal to the second preset change amplitude threshold, step S214 is performed.

[0117] In a case where the first change trend indicates that the change amplitude of the data collected by the first light sensor is greater than the first preset change amplitude threshold and / or the second change trend indicates that the change amplitude of the data collected by the second light sensor is greater than the second preset change amplitude threshold, step S215 is performed.

[0118] In step S210, a first change trend of the data collected by the first light sensor and a third change trend of a ratio between the data collected by the first light sensor and the data collected by the second light sensor are determined.

[0119] In step S211, it is determined whether the first change trend and the third change trend are the same.

[0120] In a case where it is determined that the first change trend and the third change trend are the same, step S214 is performed.

[0121] In a case where it is determined that the first change trend and the third change trend are not the same, step S215 is performed.

[0122] In step S212, a second variation trend of the data collected by the second light sensor and a third variation trend of a ratio between the data collected by the first light sensor and the data collected by the second light sensor are determined.

[0123] In step S213, it is determined whether the second variation trend and the third variation trend are the same.

[0124] In a case where it is determined that the second variation trend and the third variation trend are the same, step S214 is performed.

[0125] In a case where it is determined that the second variation trend and the third variation trend are not the same, step S215 is performed.

[0126] In step S214, a third historical light-sensing data used by the terminal to adjust the screen brightness at the last time is taken as the target light-sensing data.

[0127] In step S215, a maximum value between the first light-sensing data and the third light-sensing data is taken as the target light-sensing data.

[0128] In step S216, the screen brightness of the terminal is adjusted according to the target light-sensing data.

[0129] With the above method, firstly, it can be determined whether the data collected by the second light sensor has a large fluctuation according to the second light-sensing data and the second historical light-sensing data, so that the third light-sensing data of the second light sensor can be determined more accurately. Secondly, the target light-sensing data used to adjust the screen brightness is determined according to the first light-sensing data, the third light-sensing data, the first historical light-sensing data and the second historical light-sensing data. In this way, the target light-sensing data used to adjust the screen brightness can be determined more accurately by comparing the current data and the historical data, so that the adjustment effect of the screen brightness is improved and the user experience is improved.
