Detailed ways

The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, but not to limit the present disclosure.

FIG. 1 is a flow chart of a color adjustment method according to an exemplary embodiment. As shown in FIG. 1 , the method includes S101 to S103.

In S101, the target chromaticity coordinates corresponding to the color to be adjusted of the target device are determined, wherein the display color of the target device is formed by mixing a plurality of reference colors.

In the present disclosure, the target device may be, for example, a projection device, a television, a display device, an ambient light, a lighting lamp, and the like. In addition, the display color of the target device may be formed by mixing multiple reference colors, wherein the number of reference colors may be two, three, four, or even more, which is not specifically limited in the present disclosure.

In addition, the plurality of reference colors may be various colors, which are not specifically limited in the present disclosure. For example, the multiple reference colors include red, green, and blue, that is, the display color of the target device (ie, the color presented by the target device) can be formed by mixing red, green, and blue. For another example, the multiple reference colors include yellow and cyan, that is, the display color of the target device can be formed by mixing yellow and cyan.

In S102, a target color adjustment parameter value corresponding to each reference color is determined according to the number of reference colors, the target chromaticity coordinates, the reference color value of each reference color, and the response relationship corresponding to each reference color.

In the present disclosure, the reference color value may be XYZ data in the XYZ color space. Among them, the XYZ color space is the XYZ color space defined by the International Commission on Illumination (CIE) in 1931, also known as CIE1931.

The response relationship is used to represent the corresponding relationship between the color adjustment parameter corresponding to the reference color and the response parameter of the reference color, wherein the response relationship is established in advance. The target device can adjust the display color of the target device by adjusting the value of the color adjustment parameter corresponding to different reference colors, so that the target device presents the desired color. Analog signals such as empty ratio.

In S103, color adjustment is performed on the target device according to the target color adjustment parameter value corresponding to each reference color, so as to adjust the display color of the target device to the color to be adjusted.

Illustratively, the above-mentioned target device is a projection device, which adjusts the color to achieve white balance, and the multiple reference colors include red, green, and blue, wherein, in S102, the target color adjustment parameter value corresponding to red and the target corresponding to green are obtained in S102. After the color adjustment parameter value and the target color adjustment parameter value corresponding to blue, the gain coefficient of the red channel in the projection device can be adjusted to the target color adjustment parameter value corresponding to red/the upper limit value of the color adjustment parameter (for example, 1024), At the same time, adjust the gain coefficient of the green channel to the target color adjustment parameter value corresponding to green/the above upper limit value, and adjust the gain coefficient of the blue channel to the target color adjustment parameter value corresponding to blue/the above upper limit value, so as to realize the projection The white balance of the device.

For another example, for the lighting lamp, it includes one red lamp bead and one yellow lamp bead, that is, the multiple reference colors include red and yellow, wherein, the color adjustment parameter corresponding to each reference color is current, then the red corresponding color is obtained through S102. After the target current value and the target current value corresponding to yellow, the red lamp beads can be controlled to output the target current value corresponding to red, and the yellow lamp beads can output the target current value corresponding to yellow, so that the lighting lamp can display the color to be displayed.

The specific implementation of determining the target chromaticity coordinates corresponding to the to-be-adjusted color of the target device in the above S101 will be described in detail below.

In one embodiment, the target chromaticity coordinates can be determined according to the user's adjustment operation (for example, the user can adjust the color presented by the target device through a color adjustment button on the target device). For example, the corresponding target chromaticity coordinates may be determined according to information such as target brightness and contrast input by the user.

In another implementation manner, the target chromaticity coordinates may be determined adaptively according to changes in ambient light.

In yet another embodiment, the target chromaticity coordinates may be determined according to the main color of the reference device corresponding to the target device, wherein the display color of the target device changes with the change of the main color of the reference device, wherein the main color is The color with the highest proportion among the multiple colors that make up the reference device. For example, the target device is an ambient light, and the reference device is a projection device, that is, the color of the ambient light changes with the main color of the projection device.

In addition, the above response relationship can be constructed by the following steps:

For each reference color: first, set the color adjustment parameter value corresponding to the reference color as the upper limit value of the color adjustment parameter, at the same time, set the color adjustment parameter value corresponding to other reference colors in the multiple reference colors to zero, then , obtain the first color value of the light projected by the target device; next, set the color adjustment parameter value corresponding to the reference color to several other values (for example, the upper limit of 1/2, the upper limit of 1/3) value, the upper limit value of 2/3, etc.), at the same time, the color adjustment parameter values corresponding to other reference colors in the multiple reference colors are still zero. Two-color value; finally, according to the first color value and each second color value, determine the response relationship corresponding to the reference color, that is, the corresponding relationship between the color adjustment parameter corresponding to the reference color and the response parameter of the reference color

In the present disclosure, the value ranges of the color adjustment parameters corresponding to each reference color may be the same. In addition, the light projected by the target device can be received through the sensing module, so as to obtain the color value (including the first color value and the second color value) of the light projected each time. After that, the target device communicates with the sensing module by The color value of each projected light can be obtained. The sensing module may be a color temperature sensor, a camera, an illuminance meter, an integrating sphere, etc., and the sensing module may be connected to the target device through a wireless network or a wired network.

The above-mentioned response relationship may be a response function. Under each of the above numerical values, the second color value of the light projected by the target device=the first color value of the light projected by the target device*response function (referred to as Equation 1), wherein the independent variable of the response function is the reference The color adjustment parameter corresponding to the color, and the dependent variable of the response function is the response parameter of the parameter color; in this way, for each reference color, the first color value and each second color value of the light projected by the target device can be obtained according to the above steps. The color value is determined, and the response function is determined, that is, the corresponding relationship between the color adjustment parameter corresponding to the reference color and the response parameter of the parameter color is obtained. Specifically, for each second color value, the first color value and the second color value can be substituted into the above equation 1, so as to obtain a set of equations, and then the response function can be calculated according to the set of equations.

For example, the reference color is red, and the response parameter corresponding to red

Among them, IRE _R is the color adjustment parameter corresponding to red, and Gamma is the gamma value of the target device, that is, the color adjustment parameter corresponding to red and the response parameter corresponding to red conform to the Gamma characteristic.

The following is a specific implementation of determining the target color adjustment parameter value corresponding to each reference color according to the number of reference colors, target chromaticity coordinates, the reference color value of each reference color, and the response relationship corresponding to each reference color in the above S102 method is explained in detail. Specifically, it can be implemented through the following steps 1) to 4).

1) For each reference color, determine the reference chromaticity coordinates of the reference color according to the reference color value of the reference color.

Illustratively, the reference color values (X, Y, Z) can be converted to reference chromaticity coordinates (x, y) by the following equation (1):

2) Determine the first target reference color from the plurality of reference colors.

In the present disclosure, the first target reference color is used to form the color to be adjusted, that is, when the target device is working, part of the reference colors in the multiple reference colors can be mixed to form the color to be displayed, and the other part of the reference color does not play any role in the color to be displayed , that is, the target color adjustment parameter values corresponding to another part of the reference color are all zero. Wherein, the first target reference color is used to form the color to be adjusted, and the target color adjustment parameter of the first target reference color is not zero. In addition, the to-be-adjusted colors may all be composed of the first target reference color, or may be composed of the first target reference color and other reference colors.

3) Determine the target color adjustment corresponding to each first target reference color according to the target chromaticity coordinates, the corresponding response relationship of each first target reference color, and the reference color value and reference chromaticity coordinates of each first target reference color parameter value.

4) If the multiple reference colors also include other reference colors other than the first target reference color, at least according to the number of reference colors, determine the target color adjustment parameter values corresponding to the other reference colors.

For example, if the number of the multiple reference colors is greater than the number of the first target reference color, the multiple reference colors also include other reference colors except the first target reference color. In this case, according to the number of reference colors, Determine the target color adjustment parameter values corresponding to other reference colors; if the number of multiple reference colors is equal to the number of the first target reference color, the multiple reference colors do not include other reference colors except the first target reference color, that is, The number of other reference colors is zero, and in this case, the step of determining the target color adjustment parameter values corresponding to the other reference colors at least according to the number of reference colors is no longer performed.

The specific implementation of determining the first target reference color from a plurality of reference colors in the above step 2) will be described in detail below.

In one embodiment, when the number of reference colors is less than or equal to 3, each reference color is determined as the first target reference color. Specifically, if the number of reference colors is 2, the 2 reference colors are determined as the first target reference colors respectively, that is, the number of the first target reference colors is 2; if the number of reference colors is 3, then The three reference colors are respectively determined as the first target reference colors, that is, the number of the first target reference colors is three.

In another embodiment, when the number of reference colors is greater than 3, three first target reference colors are determined from the plurality of reference colors, so that the point corresponding to the target chromaticity coordinates falls on the three first targets Inside the triangle formed by the points corresponding to the reference chromaticity coordinates of the reference color.

In the present disclosure, if the point corresponding to the target chromaticity coordinates falls within the triangle formed by the points corresponding to the reference chromaticity coordinates of the three first target reference colors, it indicates that the color to be adjusted can be determined only by the three first target reference colors. The reference colors are mixed. At this time, among the multiple reference colors, other reference colors except the three first target reference colors may not participate in the color mixing, that is, the target color adjustment parameter values corresponding to these other reference colors are all zero. Of course, the color to be adjusted may also be formed by mixing the three first target reference colors and other reference colors among the multiple reference colors. In addition, the number of triangles formed by the points corresponding to the reference chromaticity coordinates of the multiple reference colors is multiple, and the points corresponding to the target chromaticity coordinates may fall within two or even more triangles among the above-mentioned multiple triangles. , it is only necessary to determine the reference colors corresponding to the coordinates of the three vertices of any one of the above two or even more triangles as the three first target reference colors.

For example, as shown in FIG. 2 , the display color of the target device is formed by mixing five reference colors (ie, G, B, R, A, K). It can be seen from FIG. 2 that the target chromaticity coordinates corresponding to the color M to be adjusted are mixed. The point M1 corresponding to (x _m , y _m ) falls into the triangle G1B1R1, the triangle B1R1A1, and the triangle B1R1K1, wherein the triangle G1B1R1 is defined by the reference color G of the reference chromaticity coordinates (x _g , y _g ) corresponding to the point G1, the reference color The point B1 corresponding to the reference chromaticity coordinates (x _b , y _b ) of B and the point R1 corresponding to the reference chromaticity coordinates (x _r , y _r ) of the reference color R are formed. The triangle B1R1A1 is composed of the reference chromaticity coordinates of the reference color B. The point B1 corresponding to (x _b , y _b ), the point R1 corresponding to the reference chromaticity coordinates (x _r , y _r ) of the reference color R, and the point corresponding to the reference chromaticity coordinates (x _a , y _a ) of the reference color A A1 is formed, the triangle B1R1K1 is composed of the point B1 corresponding to the reference chromaticity coordinates (x _b , y _b ) of the reference color B, the point R1 corresponding to the reference chromaticity coordinates (x _r , y _r ) of the reference color R, and the reference color K The reference chromaticity coordinates (x _k , y _k ) are formed by the point K1 corresponding to the point K1, therefore, the reference color G1, the reference color B1, and the reference color R1 can be determined as the above-mentioned three first target reference colors, or the reference color B1, The reference color R1 and the reference color A1 are determined as the above three first target reference colors, and the reference color B1, the reference color R1, and the reference color K1 can also be determined as the above three first target reference colors.

In the following step 3), according to the target chromaticity coordinates, the corresponding response relationship of each first target reference color, and the reference color value and reference chromaticity coordinates of each first target reference color, determine each first target reference The specific implementation of the target color adjustment parameter value corresponding to the color will be described in detail. Specifically, the target response parameter value of each first target reference color can be determined according to the reference color value, reference chromaticity coordinates and target chromaticity coordinates of each first target reference color; then, for each first target reference color, the target response parameter value can be determined. For the target reference color, a target color adjustment parameter value corresponding to the target response parameter value of the first target reference color is determined according to the response relationship corresponding to the first target reference color.

In the present disclosure, the target response parameter value of each first target reference color can be determined through the following steps ① and ② according to the reference color value, reference chromaticity coordinates, and target chromaticity coordinates of each first target reference color :

① According to the reference color value of each first target reference color, the reference chromaticity coordinates, and the target chromaticity coordinates, determine the proportional relationship between the target response parameter values of each first target reference color.

② Determine the target response parameter value of each first target reference color according to the upper limit value and proportional relationship of the color adjustment parameter.

For example, the target response parameter value of each first target reference color can be determined by the following equation (2) according to the upper limit value and proportional relationship of the color adjustment parameter:

Wherein, R(IRE _R ) is the response parameter of the first target reference color R; G(IRE _G ) is the response parameter of the first target reference color G; B(IRE _G ) is the response parameter of the first target reference color B; R1(IRE _R ) is the proportional value corresponding to the first target reference color R in the proportional relationship; G1(IRE _G ) is the proportional value corresponding to the first target reference color G in the proportional relationship; B1(IRE _B ) is the first target reference color G in the proportional relationship A proportional value corresponding to the target reference color B; Max is the maximum value among R1 (IRE _R ), B1 (IRE _B ), and G1 (IRE _G ); N is the upper limit of the color adjustment parameter.

For example, the above proportional relationship is R1(IRE _R ): B1(IRE _B ): G1(IRE _G )=1:3:4, then R1(IRE _R )=1, B1(IRE _B )=3, G( IRE _G )=4, Max=4, N=1024, then R(IRE _R )=256, G(IRE _G )=768, and B(IRE _G )=1024.

Below for the above-mentioned step ①, according to the reference color value of each first target reference color, the reference chromaticity coordinate, the target chromaticity coordinate, determine the specific ratio relationship between the target response parameter value of each first target reference color Embodiments are described in detail.

In one embodiment, the display color of the target device is mixed by 2 reference colors, that is, the number of the first target reference color is 2. Wherein, when the colors are mixed, the point corresponding to the chromaticity coordinates of the mixed color is located on the connecting line of the points corresponding to the chromaticity coordinates of the two colors, so that the point corresponding to the target chromaticity coordinates corresponding to the color to be adjusted is located on the two On the connecting line of the points corresponding to the reference chromaticity coordinates of the first target reference color (as shown in FIG. 3 , the point M1 corresponding to the target chromaticity coordinates (x _m , y _m ) corresponding to the color M to be adjusted is located on the first target reference On the connecting line between the point G1 corresponding to the reference chromaticity coordinates (x _g , y _g ) of the color G and the point B1 corresponding to the reference chromaticity coordinates (x _g , y _g ) of the first target reference color B, that is, the point M1 is located at on line segment G1B1), and satisfy the following equation (3):

Wherein, (x _g , y _g ) are the reference chromaticity coordinates of the first target reference color G; (x _b , y _b ) are the reference chromaticity coordinates of the first target reference color B; (x _m , y _m ) are Target chromaticity coordinates; (X _B , Y _B, , Z _B ) are the reference color values of the first target reference color B; (X _G , Y _G, , Z _G ) are the reference color values of the first target reference color G .

Therefore, according to the reference color value of each first target reference color, the reference chromaticity coordinates, and the target chromaticity coordinates, the above equation (3) can be used to determine the target response parameter value of each first target reference color. proportional relationship.

In another implementation manner, the display color of the target device is formed by mixing three or more reference colors, that is, the number of the first target reference color is three. At this time, according to the reference color value of each first target reference color, the reference chromaticity coordinates, and the target chromaticity coordinates, the proportional relationship between the target response parameter values of each first target reference color can be determined in the following manner:

First, one of the three first target reference colors is determined as the second target reference color, and the other two are respectively used as the third target reference color and the fourth target reference color; then, the second target reference color and the third target reference color are determined. The first mixed chromaticity coordinates of the mixed color of the reference color, and the second mixed chromaticity coordinates of the mixed color of the second target reference color and the fourth target reference color; Next, according to the reference color value of the third target reference color and With reference to the chromaticity coordinates, the reference color value and reference chromaticity coordinates of the second target reference color, and the first mixed chromaticity coordinates, determine the difference between the target response parameter value of the second target reference color and the target response parameter value of the third target reference color. The first ratio, at the same time, according to the reference color value and reference chromaticity coordinates of the fourth target reference color, the reference color value and reference chromaticity coordinates of the second target reference color, and the second mixed chromaticity coordinates, determine the second target reference color The second ratio of the target response parameter value of the fourth target reference color to the target response parameter value of the fourth target reference color; finally, according to the first ratio and the second ratio, determine the proportional relationship between the target response parameter values of each first target reference color .

Illustratively, according to the reference color value and reference chromaticity coordinates of the third target reference color, the reference color value and reference chromaticity coordinates of the second target reference color, and the first mixed chromaticity coordinates, by the following equation (4) Determine the first ratio G(IRE _G )/B(IRE _G ) of the target response parameter value of the second target reference color and the target response parameter value of the third target reference color:

The three first target reference colors are respectively color G, color B, and color R, wherein the second target reference color is the first target reference color G, the third target reference color is the first target color B, and the fourth target reference color is the first target color B. The reference color is the first target reference color R; (x _c , y _c ) is the first mixed chromaticity coordinate.

Illustratively, according to the reference color value and reference chromaticity coordinates of the fourth target reference color, the reference color value and reference chromaticity coordinates of the second target reference color, and the second mixed chromaticity coordinates, by the following equation (5) Determine the second ratio G(IRE _G )/R(IRE _R ) of the target response parameter value of the second target reference color to the target response parameter value of the fourth target reference color:

Among them, (x _r , y _r ) is the reference chromaticity coordinate of the fourth target reference color R; (x _y , y _y ) is the second mixed chromaticity coordinate; (X _R , Y _{R ,} , Z _R ) is the first The reference color value of the four target reference color R.

The specific implementation manner of determining the first mixed chromaticity coordinates of the mixed color of the second target reference color and the third target reference color will be described in detail below. Specifically, the first straight line where the point corresponding to the reference chromaticity coordinate of the third target reference color and the point corresponding to the reference chromaticity coordinate of the second target reference color and the reference color of the fourth target reference color may be determined. The second straight line where the point corresponding to the degree coordinates and the point corresponding to the target chromaticity coordinate are located; then, the coordinates of the intersection of the first straight line and the second straight line are determined as the mixed color of the second target reference color and the third target reference color The first mixed chromaticity coordinates of .

In the present disclosure, the second target reference color and the third target reference color are first mixed, and it can be known that the point corresponding to the mixed chromaticity coordinates of the mixed color of the two is located at the point corresponding to the second target reference color and the third target reference color. On the first straight line where the corresponding point is located; since the color to be adjusted can be obtained by mixing the second target reference color and the third target reference color first, then the mixed color of the two is mixed with the fourth target reference color. The colors are mixed to obtain the color to be adjusted. Therefore, the point corresponding to the target chromaticity coordinate of the color to be adjusted is located on the connecting line between the point corresponding to the reference chromaticity coordinate of the fourth target reference color and the above-mentioned first straight line. The point corresponding to the mixed chromaticity coordinates of the mixed color of the second target reference color and the third target reference color is the intersection of the first straight line and the second straight line, wherein the second straight line is the reference chromaticity of the fourth target reference color The line between the point corresponding to the coordinates and the point corresponding to the target chromaticity coordinates. Therefore, the coordinates of the intersection of the first straight line and the second straight line can be used as the first mixed chromaticity coordinates. Specifically, the equation of the first straight line can be determined according to the reference chromaticity coordinates of the third target reference color and the reference chromaticity coordinates of the second target reference color, and at the same time, according to the reference chromaticity coordinates of the fourth target reference color and The reference chromaticity coordinates of the second target reference color are used to determine the equation of the second straight line. A mixed chromaticity coordinate.

For example, as shown in FIG. 4 , the second target reference color is the first target reference color G, the third target reference color is the first target color B, the fourth target reference color is the first target reference color R, and the third target reference color is the first target reference color R. The reference chromaticity coordinates of a target reference color G are (x _g , y _g ); the reference chromaticity coordinates of the first target reference color B are (x _b , y _b ); the reference chromaticity coordinates of the first target reference color R is (x _r , y _r ); at this time, the first mixed chromaticity coordinates (x _c , y _c ) of the mixed color C of the second target reference color G and the third target reference color B can be determined by the following steps: First, determine where the point B1 corresponding to the reference chromaticity coordinates (x _b , y _b ) of the third target reference color B and the point G1 corresponding to the reference chromaticity coordinates (x _g , y _g ) of the second target reference color G are located. The first straight line (ie straight line B1G1), and the point R1 corresponding to the reference chromaticity coordinates (x _r , y _r ) of the fourth target reference color R and the point M1 corresponding to the target chromaticity coordinates (x _m , y _m ) are located. Then, the coordinates of the intersection C1 of the first straight line B1G1 and the second straight line R1M1 are determined as the first and second target reference color G and the third target reference color B mixed color C Mixed chromaticity coordinates (x _c , y _c ).
