The video input device may be, but not limited to, a camera.
Meanwhile, based on the face recognition technology, the video input device at the front end of the display device can be used for acquiring the face information of a target object in front of the display device, and the eyeball focusing region can be determined based on the face information. For example, determining the eyeball focus region based on the face information may include: determining a face orientation of the target object based on the face information; and determining the eyeball focusing region of the target object according to the face orientation of the target object.
In the embodiment of the present disclosure, after determining the eyeball focus region on the display device based on the eyeball tracking technique, the display device may acquire the first color data from the image information of the eyeball focus region. In addition, the display device may acquire a projection area in which an eyeball focus area is vertically projected on the background through a rear sensor thereof, and then acquire background color data from image information of the projection area.
The first color data may be RGB values of an eyeball focus region. The background color data may be RGB values of a background area in a background of the display device; wherein, the vertical projection of the eyeball focusing region to the background covers the background region.
For example, as shown in fig. 2, which shows the positional relationship of a target object, a display device, and a background, the display device is located between the target object and the background, wherein a focusing area of an eyeball of the target object on the display device forms the eyeball focusing area; the projection of the eyeball focus region onto the background forms the background region on the background.

Therefore, the first color data of the eyeball focusing region can be adjusted to the second color data through the background color data, so that the color data of the eyeball focusing region can adapt to the change of the background, the influence of the changed background on the display effect of the display device is reduced, and better visual experience of a target object is provided.
In one embodiment of the present disclosure, step 120 may be implemented in a variety of different ways.
A specific embodiment is shown below. It should be noted that the following list is only an example and is not meant to be limiting.
Fig. 3 is a second flowchart of a color adjustment method according to an embodiment of the disclosure. Referring to fig. 3, step 120 in the color adjustment method provided in the embodiment of the present disclosure may include the following steps:

In step 121, the preset transparency may be a transparency of the display device, for example, the preset transparency may be 40%. The third color data may be color data of the first color data and the background color data adjusted based on a preset transparency; for example, the third color data may be represented by R n G n B n And (3) representing.
In the presently disclosed embodiments, transparency may be set with Alpha in the cascading style sheet (Cascading Style Sheets, CSS) filter. Wherein, the identifier of the CSS filter is "filter", and the CSS filter can be classified into a basic filter and an advanced filter. The CSS filter class can act directly on the object and the immediately effective filter is called the base filter; the filter is called a high-level filter which can generate more changeable effects by matching with a script language.
In an embodiment, the specific process of adjusting the first color data to obtain the adjusted third color data in step 121 based on the preset transparency and the background color data may include:
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;
Obtaining a 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;
and obtaining the third color data based on the first calculation result and the second calculation result.
Therefore, each color component in the third color data, namely the third color data, can be obtained through the first calculation result of each color component in the preset transparency and the background color data and the second calculation result of each color component in the preset transparency and the first color data, so that the color data of the eyeball focusing region can be prepared for the subsequent adjustment of the color data of the eyeball focusing region based on the color data after the adjustment of the preset transparency.
Here, the color component may be R, G or B in RGB; among them, the RGB mode is an additive color mode, and any color can be described by the irradiation amount of R, G, B. The range of values of the three components R, G, B is 0-255 when the color is defined by a computer, 0 indicates no stimulation, and 255 indicates that the stimulation reaches the maximum value. White was synthesized when R, G, B was 255, and black was formed when R, G, B was 0. This mode is often employed when displaying color definitions on a display device. For example, images are used for televisions, slides, networks, multimedia, and RGB modes are generally used.
In an embodiment of the disclosure, the obtaining the 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 may include: obtaining a difference value between a preset value and preset transparency; and obtaining a first calculation result of each color component in the background color data based on the product of the difference and each color component in the background color data.

For example, the preset transparency is calculated to be 40% and the preset value is 1 based on the preset transparency and the background color data R b G b B b For the first color data R a G a B a Adjusting to obtain third color data R n G n B n The calculation process of (2) may be equation (1).
Wherein R is a 、G a 、B a May be three color components of the first color data; r is R b 、G b 、B b May be three color components of the background color data; r is R n 、G n 、B n May be three color components of the third color data.
In step 122, a preset conversion matrix may be used to convert the RGB values into three-dimensional space coordinates in the color space model. The color space model is formed by reflecting the relation among brightness, hue and purity of colors in a three-dimensional space form by a color system; the color system can be a color system which is formed by orderly arranging and classifying colors according to three attributes.
It should be noted that the preset conversion matrix may be set according to an actual application, and the embodiments of the present disclosure are not limited. For example, the preset conversion matrix may be:
in the embodiment of the present disclosure, the fourth color data may be corresponding color data in a three-dimensional space obtained by converting the first color data and the background color data based on a preset conversion matrix. For example, the fourth color data may be represented by R x G x B x And (3) representing. Specifically, the first color data and the background color data can be converted into three-dimensional space coordinates based on a preset conversion matrix, then the space coordinates of the fourth color data are calculated in a color space model, and finally the fourth color data are obtained based on inverse matrix inverse conversion of the preset conversion matrix.
In an embodiment, the adjusting the fourth color data in step 123 based on the preset transparency and the third color data, to obtain the adjusted second color data may include:
obtaining a third calculation result of each color component in the third color data based on each color component in the third color data and the preset transparency;
obtaining a 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;
and obtaining the second color data based on the third calculation result and the fourth calculation result.
Therefore, each color component in the second color data, namely the second color data, can be obtained through presetting a third calculation result of each color component in the transparency and the third color data and presetting a fourth calculation result of each color component in the transparency and the fourth color data, so that the color data displayed in an eyeball focusing area can be better obtained, and better visual experience is provided for a target object.
In an embodiment of the disclosure, the obtaining the third calculation result of each color component in the third color data based on each color component in the third color data and the preset transparency may include: obtaining a difference value between a preset value and preset transparency; and obtaining a third calculation result of 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 practical situations, and the embodiments of the present disclosure are not limited. For example, the preset value may be set to 1.
The obtaining the 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: and obtaining a 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.
The obtaining the second color data based on the third calculation result and the fourth calculation result may include: obtaining a calculation result of each color component in the second color data based on a sum of a third calculation result of each color component in the third color data and a fourth calculation result of each color component in the fourth color data; the second color data is constructed based on the calculation result of each color component in the second color data.
For example, the preset transparency is calculated to be 40% and the preset value is 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 Adjusting to obtain second color data R a′ G a′ B a′ The calculation process of (2) may be the formula (2).
Wherein R is n 、G n 、B n May be three color components of the third color data; r is R x 、G x 、B x May be three color components of the fourth color data; r is R a′ 、G a′ 、B a′ May be three color components of the second color data.
In one embodiment of the present disclosure, step 122 may be implemented in a variety of different ways.
A specific embodiment is shown below. It should be noted that the following list is only an example and is not meant to be limiting.
Fig. 4 is a flowchart illustrating a color adjustment method according to an embodiment of the disclosure. Referring to fig. 4, step 122 in the color adjustment method provided in the embodiment of the present disclosure may include the following steps:
step 122a, based on the preset conversion matrix, converting the first color data and the background color data respectively to obtain a spatial coordinate of the first color data and a spatial coordinate of the background color data;
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;
And step 122c, performing inverse conversion on the space coordinates of the fourth color data based on the inverse matrix of the preset conversion matrix to obtain the fourth color data.
According to the color adjustment method provided by the embodiment of the disclosure, the first color data and the background color data can be adjusted from the dimension of the space coordinate to obtain the fourth color data, so that preparation can be made for subsequent adjustment of the color data of the eyeball focusing region, the influence of the background element on the display effect of the display device is reduced better, and better visual experience of a target object is provided.
In step 122a, the converting 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 space coordinates of the first color data based on the product of a 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 space coordinates of the background color data based on the product of the preset conversion matrix and the second column vector.
It will be appreciated that a column vector may be formed based on each color component of the first color data, and the spatial coordinates corresponding to each color component of the first color data may be obtained by multiplying the column vector by a predetermined conversion matrix. Similarly, a column vector may be formed based on each color component of the background color data, and then a predetermined conversion matrix may be multiplied by the column vector to obtain spatial coordinates corresponding to each color component of the background color data.
For example, the first color data may be represented by R a G a B a The background color data can be represented by R b G b B b A representation; accordingly, the spatial coordinates of the first color data may be represented by X a Y a Z a The spatial coordinates of the background color data can be represented by X b Y b Z b And (3) representing. The process of converting the first color data and the background color data based on the preset conversion matrix may be formula (3).
It will be appreciated that the color component R of the first color data a 、G a 、B a Input into formula (3) for calculation, and can output the space coordinate X of the first color data a Y a Z a . Similarly, the color component R of the background color data b 、G b 、B b Inputting into the formula (3) for calculation, and outputting background colorSpatial coordinates X of data b Y b Z b 。
In step 122b, the spatial locations of the first color data and the background color data may be determined based on the spatial coordinates of the first color data and the spatial coordinates of the background color data; then, in the three-dimensional space coordinate system, a point on the reverse extension of the first color data and the background color data is taken and set as the space position of the fourth color data. For example, the spatial coordinates of the fourth color data may be represented by X x Y x Z x And (3) representing.
In an embodiment, the specific process of determining the spatial coordinates of the fourth color data in step 122b based on the spatial coordinates of the first color data and the spatial coordinates of the background color data may include:
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;
and determining the space coordinates of the fourth color data based on the preset transparency and the first space distance.
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 spatial coordinate system, and then the fourth color data of the other dimension after the first color data is adjusted can be obtained later, so that preparation is made for the subsequent adjustment of the color data of the eyeball focusing region.
In an embodiment of the disclosure, determining the spatial coordinates of the fourth color data based on the preset transparency and the first spatial distance may include: determining a spatial distance between the first color data and the third color data and a spatial distance between the background color data and the third color data based on a preset transparency and the first spatial distance; determining a spatial distance between fourth color data and the first color data based on a preset proportional relationship and the spatial distance between the first color data and the third 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, the spatial coordinates of the fourth color data are calculated.
The preset proportional relationship may 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.
For example, as shown in FIG. 5, the third color data R can be recorded n G n B n And the first color data R a G a B a The space distance between them isThird color data R n G n B n And background color data R b G b B b The space distance between them is->Fourth color data R x G x B x And the first color data R a G a B a The space distance between them is->The preset proportional relationship may be expressed as:
in an 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:
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;
