[0075] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0076] The screen brightness adjustment method provided in the embodiment of the present disclosure is executed by an electronic device with a display screen, and the electronic device is a terminal device such as a mobile phone, a tablet computer, a laptop computer, a wearable smart device, etc.

[0077] Figure 1 is a flowchart of a method for adjusting screen brightness according to an exemplary embodiment, which is executed by an electronic device, see Figure 1 The method comprises the following steps S101-S102:

[0078] Step S101, based on the displayed content on the screen of the electronic device, determine the category corresponding to at least one display area in the displayed content, different display areas correspond to different categories, and the category corresponding to the display area is used to represent the category to which the content displayed in the display area belongs.

[0079] In the disclosed embodiments, a variety of contents may be displayed on the screen of the electronic device. For example, the contents displayed on the screen may be at least one of videos, images, text, game screens, and the like. Under the same ambient light illumination, if different contents are to be displayed in a clearer manner, a single display brightness on the screen obviously cannot meet the requirement. For example, a video and text are displayed on the screen. Since the video is dynamically changing and contains more colors and details than the text, under the same display brightness, if the text can be displayed clearly, some details in the video may not be displayed clearly, or, if the video can be displayed clearly, the display brightness will be too bright for the text. Therefore, different display brightness adjustment methods may be applied to different contents.

[0080] The display area in the displayed content refers to the area where the content belonging to any category is located. The content displayed in the same display area belongs to the same category, and the content displayed in different display areas belongs to different categories. The category corresponding to the display area is the category to which the content displayed in the display area belongs. The category is a pre-set category of the displayed content, for example, the category includes a video category, an image category, a text category, a game category, etc.

[0081] Step S102: adjusting the display brightness of each display area based on the category corresponding to each display area.

[0082] After determining the category corresponding to each display area, for each display area, based on the category corresponding to the display area, the display brightness of the display area is adjusted; here, there is no specific limitation on how to adjust the display brightness of the display area based on the category corresponding to the display area, such as determining the brightness adjustment curve corresponding to the current display area category based on the pre-set correspondence between the display area category and the brightness adjustment curve, so as to adjust the display brightness of the display area according to the determined brightness adjustment curve. Among them, the way different categories are used to adjust the display brightness of the corresponding display areas can be the same or different.

[0083] The method provided by the embodiment of the present disclosure determines, based on the display content on the screen of the electronic device, a category corresponding to at least one display area in the display content, the category corresponding to the display area is used to characterize the category to which the content displayed in the display area belongs, and then adjusts the display brightness of each display area based on the category corresponding to each display area, that is, it is possible to implement regional display brightness adjustment for display content belonging to different categories, so that the display brightness of different display areas is more matched with the display content in the display area, thereby improving the display effect of the display content on the screen. Moreover, for the user, it is possible to avoid the situation where there are multiple display contents on the screen but the display brightness of different display areas is the same, so that some display contents appear to the user to have too high display brightness, or some display contents appear to the user to have too low display brightness, thereby having a better eye protection effect and improving the user experience.

[0084] Figure 2 is a flowchart of another method for adjusting screen brightness according to an exemplary embodiment, which is executed by an electronic device, see Figure 2 , the method comprises the following steps:

[0085] Step S201 , starting a target function, where the target function is a function of adjusting display brightness based on the category to which the displayed content on the screen belongs.

[0086] In the embodiment of the present disclosure, in order to achieve the purpose of adjusting the display brightness of display content belonging to different categories in different regions, a target function is provided, that is, a function of adjusting the display brightness based on the category to which the display content on the screen belongs. Before adjusting the display brightness, the target function is turned on first.

[0087] In some embodiments, a brightness adjustment switch is provided in the electronic device, and when the brightness adjustment switch is turned on, the target function is determined to be turned on, and when the brightness adjustment switch is turned off, the target function is determined to be turned off. For example, the brightness adjustment switch is provided in the system settings of the electronic device.

[0088] Optionally, when the target function is turned off, the electronic device adjusts the display brightness of each display area in the screen based on the single brightness adjustment information, and the display brightness of each display area is the same after the adjustment. The single brightness adjustment information may be a brightness adjustment curve for adjusting the display brightness of the screen, and the brightness adjustment curve is used to uniformly adjust the display brightness of each display area in the screen.

[0089] In the disclosed embodiment, the user can freely choose whether to adjust the display brightness in different regions or to uniformly adjust the brightness of the entire screen, thereby improving the flexibility of display brightness adjustment.

[0090] It should be noted that step S201 is an optional operation. In some embodiments, step S201 may not be performed. The electronic device turns on the target function by default and directly performs the following screen brightness adjustment process.

[0091] Step S202: determining, based on the displayed content on the screen of the electronic device, a category corresponding to at least one display area in the displayed content.

[0092] For the displayed content on the screen, the displayed content may include content belonging to at least one category.

[0093] In some embodiments, when the electronic device displays the display content on the screen, it reads at least one category corresponding to the display content and the display area where the content belonging to each category is located from the program running in the background, thereby determining the category corresponding to at least one display area in the display content. For example, if the electronic device displays both video and text, the text category to which the text belongs and the video category to which the video belongs, as well as the display area where the text is located and the display area where the video is located can be read from the program running in the background.

[0094] In some embodiments, the electronic device identifies the displayed content on the screen, identifies the category to which each content in the displayed content belongs, and the display area where the content belonging to each category is located.

[0095] In some embodiments, the screen includes a first display area and a second display area, the content displayed in the first display area belongs to a first category, and the content displayed in the second display area belongs to a second category. The first category is different from the second category, and under the same ambient light illumination, the display brightness of the display area corresponding to the first category is greater than the display brightness of the display area corresponding to the second category. For example, the first category is a video category, and the second category is a text category, or the first category is an image category, and the second category is a text category, or the first category is a video category, and the second category is an image category.

[0096] In this case, based on the displayed content on the screen of the electronic device, determining the category corresponding to at least one display area in the displayed content includes: obtaining a first proportion of the first display area in the screen; when the first proportion is less than or equal to a preset proportion, determining that the first display area and the second display area correspond to the second category; when the first proportion is greater than the preset proportion, determining that the first display area corresponds to the first category and the second display area corresponds to the second category. The preset proportion is a preset proportion, for example, the preset proportion is 35%, 30% or other smaller proportions.

[0097] When the first ratio is less than or equal to the preset ratio, it means that the first display area occupies a smaller area on the screen, and the second display area occupies a larger area on the screen, and under the same ambient light illumination, the display brightness of the display area corresponding to the first category is greater than the display brightness of the display area corresponding to the second category, that is, under the same ambient light illumination, the first display area is brighter than the second display area, which will lead to a problem that the display brightness is brighter but the user cannot see the details of the content because the displayed content is too small. In order to avoid this problem, it is determined that the first display area and the second display area correspond to the second category, that is, the display brightness of the first display area and the second display area are adjusted according to the second category, so that the display brightness of the first display area will not be too bright, thereby saving some power consumption while ensuring the user experience as much as possible.

[0098] For example, see Figure 3 In the schematic diagram of the display interface shown in FIG. 1 , a “video playback area” is displayed in the upper left corner of the display interface. The video playback area is the first display area, which corresponds to the video category. The other display areas except the video playback area are the second display areas, which correspond to the text category. Figure 3 It can be seen that the first display area occupies a relatively small area in the entire display interface. In this case, the display brightness of the video playback area and other display areas is adjusted according to the text category.

[0099] When the first ratio is greater than the preset ratio, it means that the first display area occupies a larger area of ​​the screen, and the user can clearly see the details of the content displayed in the first display area. Therefore, it is determined that the first display area corresponds to the first category and the second display area corresponds to the second category, that is, the display brightness of the first display area is adjusted according to the first category, and the display brightness of the second display area is adjusted according to the second category, so that the user can better view the details of the content displayed in the first display area.

[0100] For example, see Figure 4 The schematic diagram of the display interface shown in the figure is a video playback interface. In the video playback interface, most of the area is the video playback area, and a small part of the area displays other information. The video playback area is the first display area, and the first display area corresponds to the video category. The other display areas except the video playback area are the second display areas, and the second display area corresponds to the text category. Figure 4 It can be seen that the first display area occupies a relatively large area in the entire display interface. In this case, the video playback area is adjusted for display brightness according to the video category, and the brightness of other display areas is adjusted according to the text category.

[0101] In some embodiments, the first proportion of the first display area in the screen is obtained using the following formula:

[0102]

[0103] Ratio1 represents the first ratio, W1 represents the length of the first display area, H1 represents the width of the first display area, and W Screen Indicates the length of the screen, H Screen Indicates the width of the screen.

[0104] Among them, W1, H1, W Screen and H Screen It can be read from the program code running in the background, or recognized by the electronic device.

[0105] It should be noted that the above-mentioned embodiment is only described by taking the screen including the first display area and the second display area, that is, the screen having two display areas corresponding to the categories as an example. In another embodiment, when the screen includes three, four or even more display areas, the proportion of each display area in the screen is determined respectively. For each display area, when the proportion of the display area in the screen is less than or equal to the preset proportion, the display brightness of the display area is adjusted according to the second category, and when the proportion of the display area in the screen is greater than the preset proportion, the display brightness of the display area is adjusted according to the category corresponding to the display area. Among them, the second category is a text category, or the second category is the category with the darkest display brightness among the categories corresponding to multiple display areas, that is, under the same ambient light illumination, the display brightness of the display area corresponding to the second category is less than the display brightness of the display areas corresponding to other categories.

[0106] Step S203, obtaining brightness adjustment information of a category corresponding to each display area.

[0107] The brightness adjustment information of different categories is different, and the brightness adjustment information of a category is used to represent: the display brightness of the display area corresponding to the category under each ambient light illumination.

[0108] In some embodiments, the brightness adjustment information is a brightness adjustment curve, which represents the corresponding relationship between each ambient light illumination and the display brightness, wherein each category has a corresponding brightness adjustment curve.

[0109] For example, referring to the following Table 1, the categories of displayed content include video category, image category and text category:

[0110] Table 1

[0111] Display content categories Brightness adjustment curve Video Category Curve A Image Category Curve B Text category Curve C

[0112] See also Figure 5 The schematic diagram of the brightness adjustment curve shown in FIG. 1 is a diagram of the brightness adjustment curve of the video category. Figure 5 Curve A in the figure, the brightness adjustment curve of the image category is Figure 5 Curve B in the figure, the brightness adjustment curve of the text category is Figure 5 Curve C in .

[0113] Optionally, for the above Figure 5 The curves A, B and C shown can be determined by the following formula:

[0114] For the video category, since the video is dynamically changing and contains more colors and content details than images and text, the color or content details of the video may not be presented at a lower brightness. Therefore, the video category corresponds to the brightest brightness adjustment curve A, from Figure 5 It can be seen that under the same ambient light illumination, the display brightness corresponding to curve A is greater than the display brightness corresponding to curve B and curve C. The expression of curve A is shown in the following formula, which shows that the display brightness corresponding to the video category is controlled by the functional relationship composed of ambient light illumination and three constants:

[0115]

[0116] Among them, Lv A Indicates the display brightness corresponding to the video category, I env Indicates the ambient light intensity, A A , B A and C A There are three preset constants.

[0117] For the image category, since the image is static, the color and details of the image can be clearly seen without reaching the display brightness of the video category. Therefore, the image category corresponds to the brightness adjustment curve B with moderate brightness. Figure 5 It can be seen that under the same ambient light illumination, the display brightness corresponding to curve B is greater than the display brightness corresponding to curve C, but less than the display brightness corresponding to curve A. The expression of curve B is shown in the following formula, which shows that the display brightness corresponding to the image category is controlled by the functional relationship composed of ambient light illumination and three constants:

[0118]

[0119] Among them, Lv B Indicates the display brightness corresponding to the image category, I env Indicates the ambient light intensity, A B , B B and C B There are three preset constants.

[0120] For the text category, all display contents except videos and images are defined as text. Since most scenes use white background and black font to display text, it has a very high contrast and does not require high brightness. Therefore, the text category corresponds to the darkest brightness adjustment curve C. Figure 5 It can be seen that under the same ambient light illumination, the display brightness corresponding to curve C is smaller than the display brightness corresponding to curve A and curve C. The expression of curve C is shown in the following formula, which shows that the display brightness corresponding to the text category is controlled by the functional relationship composed of ambient light illumination and three constants:

[0121]

[0122] Among them, Lv C Indicates the display brightness corresponding to the text category, I env Indicates the ambient light intensity, A C , B C and C C There are three preset constants.

[0123] It should be noted that the three constants preset in the above three formulas are different.

[0124] In some embodiments, the brightness adjustment information is a correspondence table, which includes a plurality of ambient light illuminations and a display brightness corresponding to each ambient light illumination, wherein each category has its own correspondence table.

[0125] In some embodiments, brightness adjustment information of each category is stored in the electronic device, and when the display brightness needs to be adjusted, the stored brightness adjustment information is called.

[0126] It should be noted that in the embodiments of the present disclosure, the brightness adjustment information is only described as a brightness adjustment curve or a corresponding relationship table. In another embodiment, the brightness adjustment information can also be in other forms. The embodiments of the present disclosure do not limit the specific form of the brightness adjustment information.

[0127] Step S204: adjusting the display brightness of each display area based on the brightness adjustment information of each category.

[0128] In the disclosed embodiment, since each category has its own brightness adjustment information, when adjusting the display brightness of the display area corresponding to each category, the display brightness of the display area corresponding to the category can be adjusted directly based on the brightness adjustment information of the category.

[0129] In some embodiments, for each category, the display brightness of the display area corresponding to the category is adjusted to the display brightness represented by the brightness adjustment information of the category.

[0130] In some embodiments, for the above-mentioned implementation of determining the categories corresponding to the first display area and the second display area, when it is determined that the first display area and the second display area correspond to the second category, the display brightness of the first display area and the second display area is adjusted based on the brightness adjustment information of the second category; or, when it is determined that the first display area corresponds to the first category and the second display area corresponds to the second category, the display brightness of the first display area is adjusted based on the brightness adjustment information of the first category, and the display brightness of the second display area is adjusted based on the brightness adjustment information of the second category. By adjusting the display brightness according to the determined category, it can be ensured that the display brightness of each display area is suitable for the display brightness of the display area, so that the user can better view the display content at the display brightness.

[0131] In the embodiments of the present disclosure, it is taken into consideration that when adjusting the display brightness, if the display brightness of the screen in hardware does not reach the required maximum display brightness, then no matter how the pixel value is adjusted, the display brightness cannot reach the maximum display brightness. Therefore, it is necessary to first make the display brightness reach the required maximum display brightness in hardware, and then reduce the display brightness of certain display areas by adjusting the pixel value, so that the display brightness of each display area can be adjusted to an appropriate display brightness.

[0132] In some embodiments, there are multiple display areas in the display content, and based on the brightness adjustment information of each category, the display brightness of each display area is adjusted, including: selecting the first brightness adjustment information from the brightness adjustment information of multiple categories, wherein, under the same ambient light illumination, the display brightness represented by the first brightness adjustment information is greater than the display brightness represented by other brightness adjustment information. Based on the first brightness adjustment information, the screen backlight parameter of the electronic device is adjusted, and the screen backlight parameter is a parameter for adjusting the display brightness on the hardware of the electronic device. The display brightness can be adjusted on the hardware by adjusting the screen backlight parameter. Then, based on the first brightness adjustment information and the second brightness adjustment information, the pixel value of the third display area is adjusted, wherein the third display area is the display area where the content belonging to the third category is located, and the third category is the category corresponding to the second brightness adjustment information, that is, after the overall display brightness of the screen is adjusted on the hardware, for some display areas whose display brightness does not need to reach the display brightness, the display brightness of the display area is dimmed according to the brightness adjustment information corresponding to the display area.

[0133] In some embodiments, based on the first brightness adjustment information and the second brightness adjustment information, the pixel value of the third display area is adjusted, including: obtaining the first pixel value of the fourth display area, the fourth display area is the display area where the content belonging to the fourth category is located, and the fourth category is the category corresponding to the first brightness adjustment information; obtaining the first display brightness and the second display brightness, the first display brightness is the display brightness represented by the second brightness adjustment information under the current ambient light illumination, and the second display brightness is the display brightness represented by the first brightness adjustment information under the current ambient light illumination; determining the ratio between the first display brightness and the second display brightness; determining the second pixel value based on the first pixel value and the ratio, and adjusting the pixel value of the third display area to the second pixel value. The ratio can represent the difference in display brightness between the third display area and the fourth display area, and the second pixel value is determined according to the ratio and the first pixel value of the fourth display area, and the second pixel value is the pixel value of the third display area.

[0134] Optionally, the pixel value is an RGB value, and the pixel value of the third display area is determined by the following formula:

[0135]

[0136]

[0137]

[0138] Among them, R1, G1 and B1 represent the RGB values ​​of the third display area, R0, G0 and B0 represent the RGB values ​​of the fourth display area, It represents the ratio between the first display brightness and the second display brightness, Lv1 is the first display brightness, and Lv0 is the second display brightness.

[0139] For example, see Figure 6 Schematic diagram of different display areas shown in FIG. 1 . For the video playback area and the comment area, the video playback area corresponds to curve A, and the comment area corresponds to curve C. When the ambient light remains unchanged, curve A is always higher than curve C. When adjusting the display brightness of the screen, the screen backlight parameters are adjusted based on curve A. At this time, the display brightness of the video playback area is adjusted to Figure 6 The display brightness shown in , and the display brightness of the comment area is adjusted based on curve C. At this time, the screen backlight parameters are fixed. Then, according to the display brightness difference between curve A and curve C, the display brightness difference is converted into RGB value difference. The pixel value of the comment area is determined based on the above formula, and the pixel value of the comment area is adjusted to the determined pixel value. At this time, the display brightness of the comment area is adjusted to Figure 6 The display brightness shown in Figure 6 It can be seen that the display brightness of the video playback area is significantly higher than that of the comment area.

[0140] Step S205 , in response to detecting a brightness bar display operation, displaying a corresponding brightness bar in each display area, wherein the brightness bar is used to adjust the display brightness of the display area where the brightness bar is located.

[0141] In the disclosed embodiment, when there are multiple display areas, if the user needs to manually adjust the display brightness, after triggering the brightness bar display operation, the electronic device displays a corresponding brightness bar in each display area, each brightness bar is used to adjust the display brightness of the display area where the brightness bar is located, that is, for multiple display areas, when the display brightness of a display area is adjusted through the brightness bar corresponding to the display area, the display brightness of other display areas remains unchanged. By setting the brightness bar in different areas, the user can flexibly adjust the display brightness of each display area, thereby improving the flexibility of manually adjusting the display brightness.

[0142] For example, see Figure 6 , corresponding brightness bars are displayed in the video playback area and the comment area respectively. The display brightness of the video playback area can be adjusted through the brightness bar of the video playback area. When the display brightness of the video playback area changes, the display brightness of the comment area remains unchanged; or, the display brightness of the comment area can be adjusted through the brightness bar of the comment area. When the display brightness of the comment area changes, the display brightness of the video playback area remains unchanged.

[0143] It should be noted that the above step S205 is an optional implementation.
