Fig. 1 is a flowchart illustrating a method for determining ambient brightness according to an exemplary embodiment, where the method illustrated in fig. 1 is applied to an electronic device, the electronic device including a screen and a light sensor, the light sensor being located below the screen, and the method illustrated in fig. 1 includes:
in step 101, color information of an image currently displayed on a screen is determined.
The color information of the image is used to indicate the color of the image. For example, the color information of an image includes which color the image displays, which color the dominant color is, which color the non-dominant color includes, and so on. As another example, the color information of an image includes only which color the dominant color of the image is.
In an alternative embodiment, the color information of the image currently displayed by the screen may be determined by: when the screen displays the image, the picture is obtained through screen capturing, and the color identification is carried out on the picture, so that the color information of the image is obtained.
When the color information of the image includes all the color information of the image, all the colors in the image are identified, and all the color information of the image is obtained.
When the color information of the image only includes the dominant color information of the image, the dominant color in the image is identified, and the dominant color information of the image is acquired.
In an alternative embodiment, there are various opportunities to determine the color information of the image currently displayed on the screen, for example, the first: if the current time and the historical time interval for last determining the ambient brightness are preset for a long time, starting to execute the operation for determining the color information of the image; second kind: if the number of frames of the image screen-refreshed after the previous determination of the ambient brightness reaches a preset number of frames, the operation of determining the color information of the image is started to be performed.
For the first, the preset time period may be set as needed and empirically. For example, the refresh rate of the screen is 120 frames/second, and the preset time period is 1s.
For the second, the preset number may be set as needed and empirically. For example, the refresh rate of the screen is 120 frames/second, the preset number of frames is 120, or the preset number of frames is 60, etc.
In step 102, a target image in a preset image set is acquired, and a difference between color information of the target image and color information of an image currently displayed on a screen satisfies a preset difference condition.
The preset image set comprises at least one preset image. The preset images in the preset image set may be solid images, for example, the preset image set includes solid light green images, solid dark green images, solid light pink images, solid dark pink images, and the like. The more preset images included in the preset image set, the finer the color division.

For example, an image having the smallest difference in color information from an image currently displayed on the screen in the preset image set may be determined as the target image.
In step 103, a target image is displayed on the screen, the target image being displayed above the light sensor.
The screen includes a target screen area and a non-target screen area, and the light sensor is located below the target screen area of the screen.
In an alternative embodiment, displaying the target image on the screen may include: the target image is displayed in the entire area of the screen or in the target screen area of the screen.
The target image is displayed on the whole screen, and the method has the characteristics of simplicity in operation, high efficiency and the like. But compared with the target image displayed in the target screen area of the screen, the target image is displayed on the whole screen, so that more influence is brought to the viewing experience of the user, and the viewing experience of the user is reduced to a certain extent.
In an alternative embodiment, assuming that the display time of each frame of image on the screen is T, the start display time of the image currently displayed on the screen is T1, the target image is displayed on the screen at a certain time from T1 to (t1+t), and when the time reaches t1+t, the display of the target image is canceled, and the next frame of image obtained continuously with the image currently displayed on the screen is displayed.
The image currently displayed by the screen includes a first partial image displayed in the target screen area and a second partial image displayed in the non-target screen area. When step 102 is performed, the target image is displayed in the target screen area of the screen and the second partial image is continuously displayed in the non-target screen area of the screen, or the target image is displayed in the target screen area of the screen, and the image display is not performed in the non-target screen area of the screen.

In an alternative embodiment, assuming that the display time of each frame of image on the screen is T, the target image may be displayed on the screen after the display time T of the image currently displayed on the screen is finished.
For example, when the display of the image currently displayed on the screen is ended, the target image is displayed in the target screen area of the screen, and the image display is not performed in the non-target screen area of the screen.
In another example, at the end of the display of the image currently displayed on the screen, the target image is displayed in the target screen area of the screen, while the partial image in the next frame image obtained continuously with the image currently displayed on the screen is displayed in the non-target screen area of the screen.
In an alternative embodiment, the operations of displaying the target image on the screen, collecting the light data by using the light sensor and determining the ambient brightness may be completed within the display time of one frame of image, and after the display time of one frame of image is finished, the following image is displayed normally. For higher screen refresh rate, the method is adopted to replace the image, so that the influence on the viewing experience of the user is small, and the user can not even perceive that the image is replaced.
In step 104, the ambient brightness is determined based on the light data detected by the light sensor and the target disturbance data determined based on disturbance data generated by the target image on the detection result of the light sensor.
The light data detected by the light sensor may include light brightness, and the object disturbance data may include brightness data.
The screen display content can interfere with the detection result of the light sensor, so that the ambient brightness determined according to the detection result of the light sensor has deviation from the real ambient brightness. In order to solve the above problems, the interference data generated by the detection result of the light sensor due to the screen display content may be used to correct the light data detected by the light sensor, and according to the corrected light data, the ambient brightness is determined, so as to improve the accuracy of the ambient brightness.
In an alternative embodiment, for each preset image in the preset image set, a corresponding relationship between the preset image and the interference data is established in advance, where the interference data only includes interference data generated by the preset image on a detection result of the light sensor. In the process of executing the method for determining the ambient brightness, after determining the target image, determining target interference data corresponding to the target image according to a pre-established corresponding relation.
In an alternative embodiment, the screen brightness may also interfere with the detection result of the light sensor. The electronic device may determine a screen brightness currently used by the screen, determine total interference data generated by the target image and the screen brightness currently used by the screen on a detection result of the light sensor, where the target interference data includes the total interference data. And correcting the sensing data detected by the sensor by using the total interference data, and determining the ambient brightness according to the corrected light data, so that the accuracy of the determination result of the ambient brightness is further improved.
In an alternative embodiment, fig. 3 is a method of plotting interference curves, according to an exemplary embodiment, referring to fig. 3, the method of plotting interference curves includes:
In step 201, for each frame of image in the preset image set, total interference data generated at different screen brightnesses and per frame of image is determined.
For any one frame image (hereinafter referred to as a preset image) in the preset image set, there are various ways of determining total interference data generated by the preset image and the screen brightness. For example, the interference data generated by the screen brightness is determined, the interference data generated by the preset image is determined, and statistics is performed on the interference data generated by the screen brightness and the interference data generated by the preset image to obtain total interference data generated by the preset image and the screen brightness.
There are various methods of counting two kinds of interference data, for example: the two kinds of interference data are directly added, or the two kinds of interference data are weighted and added, etc.
For another example, the control screen displays a preset image and controls the brightness of the screen, the difference between the light data detected by the light sensor and the standard light data is determined, and the total interference data generated by the preset image and the brightness of the screen is determined according to the difference.
In step 202, the screen brightness is taken as an abscissa, and the total interference data generated by each frame of image and the screen brightness is taken as an ordinate, so as to draw an interference curve corresponding to each frame of image.
In an alternative embodiment, for each frame of image in the preset image set, an interference curve is drawn, the interference curve takes the screen brightness as an abscissa, and the interference curve takes the total interference data generated by the image and the screen brightness as an ordinate.
The determining of the total interference data generated by the target image and the screen brightness currently used by the screen on the detection result of the light sensor may include: and acquiring an interference curve drawn for the target image, and determining total interference data corresponding to the brightness of the screen currently used by the screen on the interference curve.
