[0074] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0075] In one embodiment, Figure 1 As shown, a display parameter adjustment method is provided. Although a logical order is shown in the step diagram, in some cases, the steps shown or described may be performed in an order different from that shown in the figure. Specifically, the display parameter adjustment method may be applied to an electronic device, wherein the electronic device may include but is not limited to one or more of a smart phone, a smart TV, a tablet computer, a portable computer, a desktop computer, and a car computer.

[0076] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0077] according to Figure 1 The display parameter adjustment method shown in the figure includes at least steps S110 to S130, which are described in detail as follows:

[0078] In step S110, the number of viewers watching the screen is obtained, and the attributes of each of the viewers are obtained.

[0079] The screen may be a display screen of an electronic device. The electronic device may have its own image acquisition device, or communicate with the image acquisition device to obtain the user image in front of the screen acquired by the image acquisition device. The image acquisition device may periodically acquire the user image in front of the screen, or acquire the user image in front of the screen in real time.

[0080] In one embodiment, obtaining the number of viewers viewing the screen may include: capturing user images, performing user recognition on the user images, and matching the recognized users with saved target users; determining users matched with the target users as viewers viewing the screen; and obtaining the number of the viewers.

[0081] The image of the target user saved in advance is obtained, and the image acquisition device acquires the user image in front of the screen. The acquired user image is subjected to image recognition, and the recognized user is matched with the target user saved in advance, and the user in the user image that matches the target user is determined as the audience viewing the screen, and the number of the audience viewing the screen is acquired.

[0082] The user may be identified from the user image by a target detection algorithm, and the difference between the identified user and each target user is calculated, and the user whose difference is less than a difference threshold is determined as a user matching the target user.

[0083] In this way, only the pre-saved target users will be regarded as viewers, which realizes the differentiation of users and ensures the priority of target users.

[0084] In another embodiment, image recognition is performed on user images, each identified user is directly determined as an audience viewing the screen, and the number of the identified users is determined as the number of audience viewing the screen.

[0085] The attributes of the audience may include, but are not limited to, the audience's vision, the distance between the audience and the screen, age and / or position. The distance between the audience and the screen and the position of the audience may be determined based on binocular ranging method or monocular ranging method.

[0086] In one embodiment, when the image of the target user is saved in advance, the static attributes of the target user such as vision and age can also be saved in advance. The static attributes of the target user can be input in advance by the user, or tested and saved in advance through the display screen. After matching the user in the user image with the target user, the vision and age of the viewer are directly obtained from the pre-saved static attributes of the target user.

[0087] In another embodiment, the age of the audience can be obtained by analyzing the appearance features of the user in the user image. The audience's vision can be determined by extracting the information of the eye position and gaze point of the audience in the user image, and then using a machine learning algorithm based on the information of the eye position and gaze point of the audience; the machine learning algorithm can refer to related technologies. The audience's vision can also be obtained by displaying a vision test chart on the display screen and testing the audience's vision using the vision test chart.

[0088] In step S120, when the number is multiple, the attributes of the target audience are determined according to the attributes of the multiple audiences.

[0089] The target audience may be one of multiple audiences, or a virtual audience determined based on the attributes of multiple audiences. When the target audience is one of multiple audiences, the attributes of the audience are directly determined as the attributes of the target audience. When the target audience is a virtual audience, the attributes of the target audience are determined based on the attributes of multiple audiences.

[0090] In step S130, the display parameters of the screen are adjusted according to the attributes of the target audience.

[0091] According to the attributes of the target audience, the display parameters of the screen are adjusted to adapt the display parameters of the screen to the attributes of the target audience.

[0092] By adopting the technical solution of the embodiment of the present application, when there are multiple viewers watching the screen, the attributes of the target audience can be determined according to the attributes of the multiple viewers, and the display parameters of the screen can be adjusted according to the attributes of the target audience. In this way, the scene with multiple viewers is taken into consideration, and the attributes of the target audience are determined according to the attributes of the multiple viewers, and the attributes of the multiple viewers are comprehensively considered. Therefore, the adjustment of the display parameters of the screen based on the attributes of the target audience is more reasonable.

[0093] Based on the above technical solution, as an embodiment, determining the attributes of the target audience according to the attributes of multiple audiences may include but is not limited to: displaying an option to select the target audience from multiple audiences, and in response to selecting any audience, determining the attributes of the selected audience as the attributes of the target audience; determining the attributes of the target audience according to statistical values ​​of the attributes of multiple audiences; or obtaining default attributes, and determining the default attributes as the attributes of the target audience.

[0094] The attributes of the target audience can be determined through at least the following three options.

[0095] In solution 1, options for selecting target audiences may be displayed on the screen, and each option is a viewer currently viewing the screen. When the user selects any of the options, the viewer corresponding to the option is determined as the target audience, and the attributes of the viewer are determined as the attributes of the target audience. The operation of selecting an option may be implemented through a TV remote control, voice, or gesture.

[0096] In the second solution, the attributes of multiple viewers can be directly obtained, and the statistical values ​​of the attributes of the multiple viewers can be obtained, and the statistical values ​​of the attributes of the multiple viewers can be determined as the attributes of the target audience. The statistical value can be an average value or a median value.

[0097] For example, there are two viewers, whose vision is 0.8 and 1.0 respectively, and whose distance is 2 meters and 2.2 meters respectively. When the statistical value is the average value, the attributes of the target audience may be: vision is 0.9, and distance is 2.1 meters.

[0098] In solution three, the default attributes can be directly obtained and determined as the attributes of the target audience. The default attributes can be attributes pre-configured in the system. The default display parameters of the screen are adjusted according to the default attributes, which can be vision-friendly display parameters derived from big data or scientific theories.

[0099] In one embodiment, the default display parameters of the screen corresponding to the default attributes may be directly saved. When the third solution is adopted, it is not necessary to obtain the default attributes, but directly obtain the saved default display parameters and adjust the display parameters of the screen to the default display parameters.

[0100] In one embodiment, when multiple viewers are detected, the above three options can be displayed on the screen first. When the user selects any option, the attributes of the target audience are obtained according to the selected option, and the display parameters of the screen are adjusted according to the attributes of the target audience.

[0101] In another embodiment, it is possible to determine which scheme should be adopted based on the attributes of multiple viewers. When the variance of the attributes of multiple viewers does not exceed the variance threshold, it is proved that the attributes of multiple viewers are relatively average. At this time, whether the attributes of the target audience are determined according to scheme one or scheme two, it will not cause too much burden on the eyes of each audience. Therefore, when the difference in the attributes of each dimension of multiple viewers does not exceed the difference threshold of the dimension, the options of scheme one and scheme two can be displayed on the screen. When the user selects any one of schemes one and two, the attributes of the target audience are obtained according to the selected scheme, and the display parameters of the screen are adjusted according to the attributes of the target audience.

[0102] When the variance of the attributes of multiple viewers exceeds the variance threshold, if the attributes of the target audience are determined according to the attributes of one viewer or the statistical value of the attributes of the audience, it may cause greater pressure on the eyes of some viewers. Therefore, when the variance of the attributes of multiple viewers exceeds the variance threshold, the attributes of the target audience can be determined according to solution three, and the display parameters of the screen can be adjusted to the default display parameters.

[0103] By adopting the technical solution of the embodiment of the present application, the attributes of multiple viewers are comprehensively considered, and the attributes of the determined target audience are relatively reasonable. The display parameters of the screen are subsequently adjusted according to the attributes of the target audience, which can ensure that the display parameters of the adjusted screen are also relatively reasonable.

[0104] On the basis of the above technical solution, if there is only one viewer watching the screen, the attributes of the viewer can be directly obtained, and the display parameters of the screen can be adjusted according to the attributes of the viewer. The method of obtaining the attributes of the viewer can refer to the method of obtaining the attributes of multiple viewers. When there is only one viewer, the method of adjusting the display parameters of the screen according to the attributes of the viewer can refer to the method of adjusting the display parameters of the screen according to the attributes of the target viewer described later.

[0105] Based on the above technical solution, Figure 2 As shown, the display parameter adjustment method may further include step S140 and step S150.

[0106] In step S140, when it is detected that the audience has changed and the number of the changed audience is plural, the display parameters of the screen are adjusted according to the attributes of the changed audience.

[0107] In step S150, when it is detected that the audience has changed and the number of the changed audience is one, the display parameters of the screen are adjusted according to the attributes of the changed audience.

[0108] The number of viewers corresponding to each user image captured by the image capture device may be recorded, and when the number of viewers changes, the display parameters of the screen may be readjusted.

[0109] When the audience changes and becomes multiple, the attributes of the target audience can be re-determined according to the attributes of the multiple audiences after the change, and the display parameters of the screen can be re-adjusted according to the attributes of the target audience. The method of re-determining the attributes of the target audience and the method of re-adjusting the display parameters of the screen can refer to the method of determining the attributes of the target audience and the method of adjusting the display parameters of the screen mentioned above.

[0110] The audience changes and becomes multiple, which may be that the number of the audience increases or decreases, or the number of the audience remains unchanged but some or all of the audience become other audiences, or the audience remains unchanged but the audience moves or other operations cause the attributes of the audience to change. The number of the audience before the change is not limited.

[0111] When the number of viewers changes and becomes one, the display parameters of the screen can be adjusted directly according to the attributes of the changed viewer. The number of viewers changes and becomes one, which may be an increase or decrease in the number of viewers, a change from one viewer to another, or a change in the viewer attributes caused by the viewer moving while the viewer remains unchanged. The number of viewers before the change is not limited.

[0112] On the basis of the above technical solution, when the audience changes and becomes multiple or one, a countdown reminder can be displayed on the screen, and the countdown reminder is used to remind the user that the display parameters of the screen will change. After the countdown ends, the display parameters of the screen are readjusted. Before the countdown ends, the user can choose to cancel the countdown. In response to canceling the countdown, the display parameters of the screen will not be readjusted, but the original display parameters will be maintained.

[0113] Optionally, when the audience changes and becomes only one, the countdown reminder may not be displayed, and the display parameters of the screen are automatically readjusted according to the attributes of the changed audience.

[0114] The technical solution of the embodiment of the present application takes into account various situations in which the audience may change, and provides different display parameter adjustment solutions for different changing situations, thereby improving user satisfaction.

[0115] On the basis of the above technical solution, the attributes of the target audience may include the eyesight of the target audience; adjusting the display parameters of the screen according to the attributes of the target audience may include: obtaining the ambient light intensity; adjusting the display brightness and / or contrast of the screen according to the eyesight of the target audience and the ambient light intensity.

[0116] The electronic device may have a built-in or external light sensor, so as to obtain the ambient light intensity based on the light sensor.

[0117] In one embodiment, the correspondence between vision and ambient light intensity and the display brightness and / or contrast of the screen is pre-configured. After the vision and ambient light intensity of the target audience are obtained, the display brightness and / or contrast of the screen can be determined by querying the configured correspondence, and the display parameters of the screen can be adjusted according to the display brightness and / or contrast.

[0118] In one embodiment, the most suitable display brightness and / or contrast for each visual acuity and each ambient light intensity can be predetermined based on big data or relevant scientific theories. After the visual acuity and ambient light intensity of the target audience are determined, the most suitable target display brightness and / or target contrast for the visual acuity and ambient light intensity of the target audience are found, and the display brightness of the screen is adjusted to the target display brightness, and / or the contrast of the screen is adjusted to the target contrast.

[0119] In another embodiment, the ambient light intensity is inversely proportional to the display brightness of the screen. If the ambient light is bright, the display brightness needs to be increased, and if the ambient light is dark, the display brightness needs to be reduced. The user's vision is proportional to the contrast of the screen. A higher contrast will produce a more vivid image, but it will be more difficult for people with poor vision to see. A lower contrast will produce a softer image, but it will be easier for people with poor vision to see. Therefore, the display brightness and / or contrast of the screen is adjusted according to the ambient light intensity and the vision of the target audience, the inverse relationship between the ambient light intensity and the display brightness of the screen, and the proportional relationship between the audience's vision and the contrast of the screen.

[0120] By adopting the technical solution of the embodiment of the present application, it is possible to ensure that the display brightness and / or contrast of the screen is suitable for the current audience, thereby optimizing the audience's visual experience and reducing the eye pressure of the audience when watching the screen.

[0121] On the basis of the above technical solution, the attributes of the target audience include the eyesight of the target audience and the distance between the target audience and the screen; adjusting the display parameters of the screen according to the attributes of the target audience may include: calculating a screen adaptive scaling factor and a text adaptive scaling factor according to the eyesight of the target audience and the distance; scaling the display image of the screen and / or adjusting the pixel density of the screen according to the screen adaptive scaling factor; scaling the text on the screen according to the text adaptive scaling factor.

[0122] In one embodiment, the screen adaptive zoom factor can be determined according to the following method: obtaining the current screen size and obtaining the recommended distance corresponding to the current screen size. Obtaining the distance of the target audience, and determining the first zoom factor according to the ratio of the distance of the target audience to the recommended distance corresponding to the current screen size. Obtaining the current environment brightness and the eyesight of the target audience, obtaining a preset comparison relationship table, and storing the second zoom factor corresponding to different environment brightness and different eyesight in the preset comparison relationship table. According to the current environment brightness and the eyesight of the target audience, query the comparison relationship table to obtain the second zoom factor. Determine the screen adaptive zoom factor according to the first zoom factor and the second zoom factor.

[0123] The current screen size can be obtained from the product manual of the electronic device or the server. The server can pre-store various parameters of the electronic device, and the server can also store a preset comparison table and a preset correspondence between different screen sizes and recommended distances. For example, the recommended distance corresponding to a 65-inch screen may be 2.5 meters, and the recommended distance corresponding to a 75-inch screen may be 3 meters, etc. According to the preset correspondence and the current screen size, the recommended distance corresponding to the current screen size can be obtained. The first scaling factor is equal to the quotient of the distance of the target audience divided by the recommended distance.

[0124] The comparison relationship table may be a comparison relationship of the second scaling factors corresponding to different ambient brightnesses and different visions obtained based on a large amount of statistical data. For example, when the ambient brightness is standard brightness and the vision is standard vision, the corresponding second scaling factor may be 1; when the ambient brightness is standard brightness and the vision is in the y1-y2 vision interval, the corresponding second scaling factor may be z1; when the ambient brightness is in the x1-x2 brightness interval and the vision is standard vision, the corresponding second scaling factor may be z2; when the ambient brightness is in the x1-x2 brightness interval and the vision is in the y1-y2 vision interval, the corresponding second scaling factor may be z3. Among them, the standard brightness and standard vision may be preset. The comparison relationship table may be obtained by the electronic device from the server, and the server may maintain and update the comparison relationship table.

[0125] The product of the first scaling factor and the second scaling factor is determined as the screen adaptive scaling factor.

[0126] In another embodiment, a recommended screen size, a recommended text size, a recommended viewing distance, and a standard vision may be predetermined.

[0127] The screen adaptive scaling factor is determined according to a first proportional relationship between the current screen size and the recommended screen size, a second proportional relationship between the distance of the target audience and the recommended viewing distance, and a third proportional relationship between the vision of the target audience and the standard vision.

[0128] Optionally, the screen adaptive scaling factor may be determined according to the following formula: screen adaptive scaling factor = second proportional relationship ÷ (first proportional relationship × third proportional relationship). If the screen adaptive scaling factor is greater than 1, it indicates that the display image of the screen needs to be enlarged and / or the pixel density of the screen needs to be increased, and if the screen adaptive scaling factor is less than 1, it indicates that the display image of the screen needs to be reduced and / or the pixel density of the screen needs to be reduced.

[0129] For example, the current screen size is 1.2, the recommended screen size is 1, the first proportional relationship is 1.2, the distance of the target audience is 1 meter, the recommended viewing distance is 2 meters, the second proportional relationship is 0.5, the target audience's vision is 0.8, the standard vision is 1, and the third proportional relationship is 0.8, then the screen adaptive scaling factor = 0.5 ÷ (1.2 × 0.8) = 0.52, then it is necessary to adjust the display picture on the screen to 0.52 times the original display picture, and / or adjust the pixel density of the screen to 0.52 times the original pixel density.

[0130] Optionally, weights may be set for the first proportional relationship, the second proportional relationship, and the third proportional relationship according to actual conditions, and the screen adaptive scaling factor may be determined using the weighted first proportional relationship, the second proportional relationship, and the third proportional relationship.

[0131] In one embodiment, the text adaptive scaling factor is determined based on a second proportional relationship between the distance of the target audience and the recommended viewing distance, a third proportional relationship between the vision of the target audience and the standard vision, and a fourth proportional relationship between the current text size and the recommended text size.

[0132] Optionally, the text adaptive scaling factor may be determined according to the following formula: text adaptive scaling factor = second proportional relationship ÷ (fourth proportional relationship × third proportional relationship). If the text adaptive scaling factor is greater than 1, it indicates that the text on the screen needs to be enlarged, and if the text adaptive scaling factor is less than 1, it indicates that the text on the screen needs to be reduced. The text on the screen may be a bullet screen, subtitles of a video, and / or text on a setting page, etc.

[0133] Optionally, the text adaptive scaling coefficient can also be determined according to the following formula: text adaptive scaling coefficient = α×second proportional relationship ÷ (β×fourth proportional relationship×γ×third proportional relationship), wherein α, β and γ are weights of the second proportional relationship, the fourth proportional relationship and the third proportional relationship, respectively, and the text adaptive scaling coefficient is determined using the weighted fourth proportional relationship, the second proportional relationship and the third proportional relationship.

[0134] By adopting the technical solution of the embodiment of the present application, the display image of the screen and the text on the screen can be scaled according to the eyesight of the target audience and the distance between the target audience and the screen, thereby ensuring that the target audience can clearly see the display image of the screen and the text on the screen, thereby reducing the eye pressure of the audience when watching the screen.

[0135] On the basis of the above technical solution, the attributes of the target audience may include the position of the target audience; adjusting the display parameters of the screen according to the attributes of the target audience may include: calculating a picture offset coefficient according to the position of the target audience; and offsetting the display picture of the screen according to the picture offset coefficient.

[0136] When the display picture of the screen is offset, the display picture on the screen may be a picture that is not displayed in full screen or a video picture played in a small window, etc. The picture that is not displayed in full screen is a picture that has been scaled and therefore does not fill the full screen. If the display picture of the screen is a full screen picture, the display picture of the offset screen will result in a partial loss of the picture.

[0137] In one embodiment, when determining the screen offset coefficient, it is necessary to determine the viewable range of the screen according to the position of the target audience and the width of the screen. Specifically, the viewable range of the screen corresponding to different offset distances and different screen widths is preset, and the corresponding relationship can be obtained in advance based on a large amount of statistical data. According to the position of the target audience, the vertical offset distance of the target audience from the electronic device is determined; and then the viewable range of the screen is determined according to the offset distance of the target audience and the width of the screen.

[0138] Determine the image offset coefficient based on the offset distance of the target audience and the viewable interval of the screen. Here, the offset distance of the target audience is a, the width of the viewable interval of the screen is z, the distance from the viewable interval to the leftmost side of the screen is c, and the distance from the viewable interval to the rightmost side of the screen is d. When the target audience is offset to the left by a, the image offset coefficient is (a÷z×2)×c; when the target audience is offset to the right by a, the image offset coefficient is (a÷z×2)×d. This ensures that the image is completely offset to the left or right edge of the screen, and the image can be fully displayed, improving the audience's visual experience.

[0139] In another embodiment, the distance between the target audience and the vertical plane of the plane where the screen is located can be determined according to the position of the target audience. The distance represents the offset distance of the target audience from the center of the screen. The offset distance is proportional to the picture offset coefficient, and the picture offset coefficient is determined according to the offset distance. The display picture of the screen is offset according to the picture offset coefficient.

[0140] For example, when the target audience is 1 meter to the left of the screen, the display image of the screen may be offset 0.1 meter to the left of the screen; when the target audience is 1.5 meters to the right of the screen, the display image of the screen may be offset 0.15 meter to the left of the screen.

[0141] Optionally, an offset distance threshold may be set. When the offset distance of the target audience from the center of the screen is less than the offset distance threshold, the screen is not offset. The screen offset coefficient is determined based on the difference between the offset distance and the offset distance threshold, and the difference between the offset distance and the offset distance threshold is proportional to the screen offset coefficient.

[0142] By adopting the technical solution of the embodiment of the present application, the displayed image on the screen is offset according to the image offset coefficient, which can enhance the audience's sense of immersion, make the audience feel that they are more in the displayed image, and improve the audience's visual experience.

[0143] Based on the above technical solution, the attributes of the target audience may include the eyesight and age of the target audience; adjusting the display parameters of the screen according to the attributes of the target audience may include: adjusting the color vision assistive function of the screen according to the eyesight of the target audience; adjusting the anti-blue light parameters of the screen according to the age and eyesight of the target audience.

[0144] When the target audience's vision indicates that the target audience is a user with color vision impairment, the color vision assistance function of the screen can be turned on. Color vision assistance function is a technology or tool that helps users with color vision impairment improve their visual experience. Color vision assistance function mainly adjusts the color parameters of the screen to replace the colors that the color vision impairment users cannot perceive with the colors that they can perceive, so that the color vision impairment users can see and distinguish colors more clearly.

[0145] Audiences of different ages are harmed by blue light to varying degrees. The lenses of children and adolescents' eyes are clearer, allowing more blue light to enter the eyes, so children and adolescents' eyes are more susceptible to blue light damage than adults. As we age, the lenses of our eyes begin to turn yellow, which naturally blocks some blue light. Adults' eyes are less sensitive to blue light than children and adolescents.

[0146] Because the eyes of people with myopia have to work harder to focus, they are more sensitive to blue light. People with hyperopia have to work harder to see close objects, so they are less sensitive to blue light.

[0147] Therefore, the screen's blue light protection parameters can be adjusted based on the audience's age and vision. The screen's blue light protection parameter level is inversely proportional to the audience's age. The younger the audience, the higher the corresponding blue light protection parameter, and the older the audience, the lower the corresponding blue light protection parameter; the more severe the audience's myopia, the higher the blue light protection parameter, and the more severe the audience's hyperopia, the lower the blue light protection parameter.

[0148] The technical solution of the embodiment of the present application takes into account the needs of viewers with color vision impairment, and the damage caused by the blue light of the screen to viewers of different age groups, and adjusts the display parameters of the screen to best meet the needs of the audience, thereby reducing the eye pressure of the audience and improving the audience's visual experience.

[0149] In one embodiment, Figure 3As shown, the static attributes of the target user are saved in advance. When the screen is turned on, the camera is called to collect the user image, and the dynamic attributes such as the position of the audience and the distance between the audience and the screen are determined based on the user image, and face recognition is performed on the user image. The audience is determined based on face recognition, and the saved static attributes of the audience are obtained. The ambient light intensity is obtained based on the light sensor. The display parameters of the screen are adjusted according to the static attributes, dynamic attributes and ambient light intensity of the audience. When the attributes of the audience change, the display parameters of the screen are readjusted.
