[0051] The technical solution of the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific embodiments. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "and / or" as used herein includes any and all combinations of one or more related listed items.

[0052] The terms "first", "second", etc. in the specification and claims of the present disclosure are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present disclosure can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects related to each other are in an "or" relationship.

[0053] The technical solutions provided by various embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0054] Figure 1 A schematic diagram of a color adjustment method provided in an embodiment of the present disclosure Figure 1 See also Figure 1 The color adjustment method provided by the embodiment of the present disclosure may include the following steps:

[0055] Step 110: Acquire first color data of the target object's eye focus area and background color data, wherein the eye focus area is the focus area of ​​the target object's eye on the display device;

[0056] Step 120: Adjust the first color data based on the background color data to obtain adjusted second color data;

[0057] Step 130: Display the second color data in the eye focus area.

[0058] In step 110, the target object may be a user using a display device; the display device may be a see-through screen, which may be applied to a home television, an exhibition display screen, a shopping mall display screen, and the like.

[0059] In the embodiments of the present disclosure, eye tracking technology can be used to obtain eye information of a target object in front of the display device using a video input device located in front of the display device. Based on this eye information, the eye focus area can be determined. The video input device can be, but is not limited to, a camera.

[0060] At the same time, facial recognition technology can also be used to obtain facial information of a target subject in front of the display device using a video input device located in front of the display device, and the eye focus area can be determined based on the facial information. For example, determining the eye focus area based on the facial information may include: determining the target subject's facial orientation based on the facial information; and determining the target subject's eye focus area based on the target subject's facial orientation.

[0061] In the disclosed embodiments, after determining the eye focus area on the display device using eye tracking technology, the display device can obtain first color data from the image information of the eye focus area. Furthermore, the display device can use its rear-mounted sensor to obtain a projection area perpendicular to the background of the eye focus area, and then obtain background color data from the image information of the projection area.

[0062] The first color data may be the RGB value of the eyeball focus area. The background color data may be the RGB value of the background area in the background of the display device; wherein the vertical projection of the eyeball focus area onto the background covers the background area.

[0063] For example, if Figure 2 As shown, it shows the positional relationship between the target object, the display device and the background, and the display device is located between the target object and the background, wherein the focusing area of ​​the target object's eye on the display device forms the eye focusing area; the projection of the eye focusing area onto the background forms the above-mentioned background area on the background.

[0064] For example, the first color data can be represented by R a G a B a Indicates that background color data can be used with R b G b B b express.

[0065] In step 120 , the second color data may be color data obtained by adjusting the first color data of the eye focus area of ​​the display device.

[0066] Understandably, after a background change, the display effect of the display device can be improved by adjusting the color data of the eye focus area. Background changes can include those caused by a change in location and scene. For example, if a display device is moved from a living room to a bedroom, the location and scene change, and the background of the display device also changes accordingly. Background changes can also include those caused by a change in the ambient light of the background. For example, if the lighting in the background area switches from a first color to a second color different from the first color.

[0067] In the disclosed embodiments, the display device may adjust the first color data, i.e., adjust the color data of the eye-focusing area on the display device. If the background of the display device changes, the display device may adjust the first color data based on the background color data to obtain new color data displayed in the eye-focusing area, i.e., the second color data.

[0068] It should be noted that adjusting the first color data to obtain the second color data may include at least one of the following: adjusting the transparency of the first color data to obtain the second color data; performing matrix change adjustment on the first color data to obtain the second color data; adjusting the spatial coordinates of the first color data to obtain the second color data; and adjusting the RGB value of the first color data to obtain the second color data.

[0069] In step 130 , the display device displays the second color data in the eye focus area, so that when the background changes, the display device improves its display effect by changing the color data of the eye focus area.

[0070] The color adjustment method provided by the disclosed embodiments obtains first color data and background color data of a target subject's eye-focusing area; adjusts the first color data based on the background color data to obtain adjusted second color data; and displays the second color data in the eye-focusing area. In this way, the first color data of the eye-focusing area can be adjusted to the second color data based on the background color data, allowing the color data in the eye-focusing area to adapt to changes in the background, thereby reducing the impact of the changing background on the display device's display effect and providing the target subject with a better visual experience.

[0071] In one embodiment of the present disclosure, step 120 may be implemented in various ways.

[0072] A specific implementation example is given below. It should be noted that the following is only an example and is not intended to be limiting.

[0073] Figure 3 A schematic diagram of a color adjustment method provided in an embodiment of the present disclosure Figure 2See also Figure 3 , step 120 in the color adjustment method provided in the embodiment of the present disclosure may include the following steps:

[0074] Step 121: Adjust the first color data based on the preset transparency and the background color data to obtain adjusted third color data;

[0075] Step 122: Determine fourth color data based on a preset conversion matrix, the first color data, and the background color data;

[0076] Step 123: Adjust the fourth color data based on the preset transparency and the third color data to obtain adjusted second color data.

[0077] The color adjustment method provided by the embodiment of the present disclosure is such that, during the process of adjusting the first color data, the display device takes into account the influence of the preset transparency and the preset conversion matrix. The adjusted second color data can correspond to more filter effects, thereby better adapting to background changes, reducing the impact of the changing background on the display effect of the display device, and providing a better visual experience for the target object.

[0078] In step 121, the preset transparency may be the transparency of the display device, for example, the preset transparency may be 40%. The third color data may be the color data obtained by adjusting the first color data and the background color data based on the preset transparency; for example, the third color data may be R n G n B n express.

[0079] In the disclosed embodiments, alpha can be used to set transparency in Cascading Style Sheets (CSS) filters. The identifier for a CSS filter is "filter," and CSS filters can be categorized into basic filters and advanced filters. CSS filters are classified as basic filters, which can be applied directly to an object and take effect immediately. Advanced filters require scripting to produce more complex effects.

[0080] In one embodiment, the specific process of adjusting the first color data based on the preset transparency and the background color data in step 121 to obtain the adjusted third color data may include:

[0081] Obtaining a first calculation result of each color component in the background color data based on each color component in the background color data and the preset transparency;

[0082] Obtaining a second calculation result for each color component in the first color data based on each color component in the first color data and the preset transparency;

[0083] The third color data is obtained based on the first calculation result and the second calculation result.

[0084] In this way, each color component in the third color data can be obtained through the preset transparency and the first calculation result of each color component in the background color data, and the preset transparency and the second calculation result of each color component in the first color data, that is, the third color data is obtained, so as to better obtain the color data of the first color data and the background color data after adjustment based on the preset transparency, and prepare for the subsequent adjustment of the color data of the eye focus area.

[0085] Here, the color component can be R, G, or B in RGB. The RGB model is an additive color model, and any color can be described by the amount of radiation emitted by R, G, and B. When a computer defines a color, the values ​​of the three components R, G, and B range from 0 to 255, where 0 indicates no stimulation and 255 indicates maximum stimulation. When R, G, and B are all 255, the result is white, and when R, G, and B are all 0, the result is black. This model is often used when displaying color definitions on a display device. For example, images used in television, slides, the internet, and multimedia generally use the RGB model.

[0086] In the embodiment of the present disclosure, obtaining the first calculation result for each color component in the background color data based on each color component in the background color data and a preset transparency may include: obtaining the difference between the preset value and the preset transparency; and obtaining the first calculation result for each color component in the background color data based on the product of the difference and each color component in the background color data. The preset value may be set according to actual circumstances and is not limited in the embodiment of the present disclosure. For example, the preset value may be set to 1.

[0087] The above-mentioned second calculation result of each color component in the first color data based on each color component in the first color data and the preset transparency may include: obtaining the second calculation result of each color component in the first color data based on the product of each color component in the first color data and the preset transparency.

[0088] The above-mentioned method of obtaining the third color data based on the first calculation result and the second calculation result may include: obtaining the calculation result of each color component in the third color data based on the sum of the first calculation result of each color component in the background color data and the second calculation result of each color component in the corresponding first color data; and constructing the third color data based on the calculation result of each color component in the third color data.

[0089] For example, by calculating the preset transparency of 40% and the preset value of 1, based on the preset transparency and background color data R b G b B b , for the first color data R a G a B a Adjust to obtain the third color data R n G n B n The calculation process can be expressed as formula (1).

[0090]

[0091] Among them, R a , G a 、B a It can be three color components of the first color data; R b , G b 、B b Can be the three color components of background color data; R n , G n 、B n It can be three color components of the third color data.

[0092] In step 122, a preset conversion matrix can be used to convert RGB values ​​into three-dimensional spatial coordinates in a color stereogram model. The color stereogram model is a color system that represents the relationship between lightness, hue, and purity in three-dimensional space. The color system can be a systematic color system that organizes and categorizes colors according to these three attributes.

[0093] It should be noted that the preset conversion matrix can be set according to actual application conditions, and the present disclosure embodiment does not limit this. For example, the preset conversion matrix can be:

[0094]

[0095] In the embodiment of the present disclosure, the fourth color data may be the corresponding color data in the three-dimensional space obtained by converting the first color data and the background color data based on a preset conversion matrix. x G x B x Specifically, the first color data and the background color data can be converted into three-dimensional space coordinates based on a preset conversion matrix, and then the spatial coordinates of the fourth color data are calculated in the color stereo model. Finally, the fourth color data is obtained by reverse conversion based on the inverse matrix of the preset conversion matrix.

[0096] In one embodiment, in step 123, the fourth color data is adjusted based on the preset transparency and the third color data to obtain the adjusted second color data. The specific process may include:

[0097] Obtaining a third calculation result for each color component in the third color data based on each color component in the third color data and the preset transparency;

[0098] Obtaining a fourth calculation result for each color component in the fourth color data based on each color component in the fourth color data and the preset transparency;

[0099] The second color data is obtained based on the third calculation result and the fourth calculation result.

[0100] In this way, each color component in the second color data can be obtained by the preset transparency and the third calculation result of each color component in the third color data, and the preset transparency and the fourth calculation result of each color component in the fourth color data, that is, the second color data is obtained, so as to better obtain the color data displayed in the eye focus area and provide a better visual experience for the target object.

[0101] In the embodiment of the present disclosure, obtaining the third calculation result for each color component in the third color data based on each color component in the third color data and a preset transparency may include: obtaining the difference between the preset value and the preset transparency; and obtaining the third calculation result for each color component in the third color data based on the product of the difference and each color component in the third color data. The preset value may be set according to actual circumstances and is not limited in the embodiment of the present disclosure. For example, the preset value may be set to 1.

[0102] The above-mentioned fourth calculation result of each color component in the fourth color data based on each color component in the fourth color data and the preset transparency may include: obtaining the fourth calculation result of each color component in the fourth color data based on the product of each color component in the fourth color data and the preset transparency.

[0103] The above-mentioned obtaining of the second color data based on the third calculation result and the fourth calculation result may include: obtaining the calculation result of each color component in the second color data based on the sum of the third calculation result of each color component in the third color data and the fourth calculation result of each color component in the fourth color data; and constructing the second color data based on the calculation result of each color component in the second color data.

[0104] For example, by calculating the preset transparency of 40% and the preset value of 1, based on the preset transparency and the third color data R n G n B n , for the fourth color data R x G x B x Adjust to obtain the second color data R a′ G a′ B a′ The calculation process can be expressed as formula (2).

[0105]

[0106] Among them, R n , G n 、B n It can be three color components of the third color data; R x , G x 、B x It can be three color components of the fourth color data; R a′ , G a′ 、B a′ It can be three color components of the second color data.

[0107] In one embodiment of the present disclosure, step 122 may be implemented in various ways.

[0108] A specific implementation example is given below. It should be noted that the following is only an example and is not intended to be limiting.

[0109] Figure 4 A schematic diagram of a color adjustment method provided in an embodiment of the present disclosure Figure 3 See also Figure 4 , step 122 in the color adjustment method provided by the embodiment of the present disclosure may include the following steps:

[0110] Step 122a: Based on the preset conversion matrix, convert the first color data and the background color data respectively to obtain the spatial coordinates of the first color data and the spatial coordinates of the background color data;

[0111] Step 122b: determining the spatial coordinates of the fourth color data based on the spatial coordinates of the first color data and the spatial coordinates of the background color data;

[0112] Step 122c: Based on the inverse matrix of the preset transformation matrix, perform inverse transformation on the spatial coordinates of the fourth color data to obtain the fourth color data.

[0113] The color adjustment method provided by the embodiment of the present disclosure can adjust the first color data and the background color data from the dimension of the spatial coordinate to obtain the fourth color data, thereby preparing for the subsequent adjustment of the color data of the eye focus area, better reducing the impact of background elements on the display effect of the display device, and providing the target object with a better visual experience.

[0114] In step 122a, the above-mentioned conversion of the first color data and the background color data based on the preset conversion matrix to obtain the spatial coordinates of the first color data and the spatial coordinates of the background color data may include: obtaining a first column vector based on each color component in the first color data; obtaining the spatial coordinates of the first color data based on the product of the preset conversion matrix and the first column vector; obtaining a second column vector based on each color component in the background color data; and obtaining the spatial coordinates of the background color data based on the product of the preset conversion matrix and the second column vector.

[0115] It is understood that a column vector can be formed based on each color component of the first color data, and the preset conversion matrix can be multiplied by the column vector to obtain the spatial coordinates corresponding to each color component of the first color data. Similarly, a column vector can be formed based on each color component of the background color data, and the preset conversion matrix can be multiplied by the column vector to obtain the spatial coordinates corresponding to each color component of the background color data.

[0116] For example, the first color data can be represented by R a G a B a Indicates that background color data can be used with R b G b B b Represented; Accordingly, the spatial coordinates of the first color data can be represented by X a Y a Z a Indicates that the spatial coordinates of the background color data can be expressed as X b Y b Z b Based on the preset conversion matrix, the process of converting the first color data and the background color data can be represented by formula (3).

[0117]

[0118] It can be understood that the color component R of the first color data a , G a 、B a Input into formula (3) for calculation, and the spatial coordinate X of the first color data can be output. a Y a Z aSimilarly, the color component R of the background color data b , G b 、B b Input into formula (3) for calculation, and the spatial coordinate X of the background color data can be output. b Y b Z b .

[0119] In step 122b, the spatial positions of the first color data and the background color data can be determined based on the spatial coordinates of the first color data and the background color data. Then, in the three-dimensional spatial coordinate system, a point on the reverse extension line of the first color data and the background color data is set as the spatial position of the fourth color data. For example, the spatial coordinates of the fourth color data can be expressed as X x Y x Z x express.

[0120] In one embodiment, the specific process of determining the spatial coordinates of the fourth color data based on the spatial coordinates of the first color data and the spatial coordinates of the background color data in step 122b may include:

[0121] obtaining a first spatial distance between the first color data and the background color data based on the spatial coordinates of the first color data and the spatial coordinates of the background color data;

[0122] Based on the preset transparency and the first spatial distance, the spatial coordinates of the fourth color data are determined.

[0123] In this way, the spatial coordinates of the fourth color data can be determined by the spatial coordinates of the first color data and the background color data in the three-dimensional space coordinate system, and then the fourth color data of another dimension after adjusting the first color data can be obtained, preparing for the subsequent adjustment of the color data of the eye focus area.

[0124] In an embodiment of the present disclosure, the above-mentioned determination of the spatial coordinates of the fourth color data based on the preset transparency and the first spatial distance may include: determining the spatial distance between the first color data and the third color data and the spatial distance between the background color data and the third color data based on the preset transparency and the first spatial distance; determining the spatial distance between the fourth color data and the first color data based on the preset proportional relationship and the spatial distance between the first color data and the third color data; and calculating the spatial coordinates of the fourth color data based on the spatial coordinates of the first color data and the spatial distance between the fourth color data and the first color data.

[0125] Among them, the preset proportional relationship can be: the ratio of the spatial distance between the first color data and the third color data to the spatial distance between the background color data and the third color data is equal to the ratio of the spatial distance between the fourth color data and the first color data to the spatial distance between the first color data and the third color data.

[0126] For example, if Figure 5 As shown, the third color data R n G n B n With the first color data R a G a B a The spatial distance between The third color data R n G n B n and background color data R b G b B b The spatial distance between Fourth color data R x G x B x With the first color data R a G a B a The spatial distance between Then the preset proportional relationship can be expressed as:

[0127] In one embodiment, the specific process of determining the spatial coordinates of the fourth color data based on the preset transparency and the first spatial distance may include:

[0128] determining a second spatial distance between the fourth color data and the first color data based on the preset transparency and the first spatial distance;

[0129] The spatial coordinates of the fourth color data are determined based on the second spatial distance and the spatial coordinates of the first color data.

[0130] In this way, the spatial coordinates of the fourth color data can be calculated in the three-dimensional space coordinate system based on the spatial coordinates of the first color data and the second spatial distance between the fourth color data and the first color data, and then the fourth color data of another dimension after adjusting the first color data can be obtained, preparing for the subsequent adjustment of the color data of the eye focus area.

[0131] In an embodiment of the present disclosure, determining the second spatial distance between the fourth color data and the first color data based on the preset transparency and the first spatial distance may include: determining the spatial distance between the first color data and the third color data and the spatial distance between the background color data and the third color data based on the preset transparency and the first spatial distance; and calculating the second spatial distance based on a preset proportional relationship and the spatial distance between the first color data and the third color data. The preset proportional relationship may be such that the ratio of the spatial distance between the first color data and the third color data to the spatial distance between the background color data and the third color data is equal to the ratio of the second spatial distance to the spatial distance between the first color data and the third color data.

[0132] For ease of understanding, combined Figure 5 and Figure 6 , here is an example:

[0133] For example, the first color data R a G a B a and background color data R b G b B b The first spatial distance between them can be d. n G n B n is the first color data R a G a B a and background color data R b G b B b Based on the color data after the preset transparency, when the preset transparency is 40%, the third color data R n G n B n With the first color data R a G a B a The spatial distance between It can be 0.6d, the third color data R n G n B n and background color data R b G b B b The spatial distance between It can be 0.4d.
