It can be seen that when the electronic device performs color correction according to the color perception curve of a standard observer, the displayed colors will still cause different observers to see different colors, which cannot solve the problem of color perception color difference between different observers, thereby reducing the The display effect of the electronic device is poor, and the intelligence is poor.

Detailed ways

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It should be understood that the specific embodiments described herein are only used to explain the related application, but not to limit the application. In addition, it should be noted that, for the convenience of description, only the parts related to the relevant application are shown in the drawings.

The electronic device needs to perform color correction to establish a corresponding relationship between the digital signal of the display channel and the display color, wherein the displayed color needs to be represented by the color perceived by the human eye. Color-corrected monitors display accurate colors.

It should be pointed out that in order to quantitatively characterize the human eye's perception of color, the International Commission on Illumination (CIE) in 1931 recommended the human eye's sensitivity spectrum curve for color by measuring the data of thousands of people, as shown in Figure 1. The CIE 1931 tristimulus spectral response curve, shown in Figure 1, is the average response to color for thousands of observers. The XYZ tristimulus response of the human eye can be obtained by integrating the spectrum reflected by the light source or the object and the corresponding wavelength of the XYZ tristimulus spectral response curve.

The human eye has receptors (called cones) for short (S), medium (M) and long (L) wavelengths of light, so in principle only three parameters can describe color perception. In the three-color additive color model, if a color and another color mixed with different weights of the three primary colors make humans look the same, we call the weights of the three primary colors the color. the tristimulus value. The CIE 1931 color space usually gives the tristimulus values of a color, represented by X, Y, and Z.

A color space refers to any method of relating each color to three numbers (or tristimulus values), and the CIE 1931 color space is one such color space. But the CIE XYZ color space is special because it is based on a direct measurement of human color vision and serves as the basis for the definition of many other color spaces.

In the CIE XYZ color space, tristimulus values do not refer to the human eye's response to short, medium, and long wavelengths (S, M, and L), but rather a set of values called X, Y, and Z, roughly corresponding to red , green and blue (where the X, Y and Z values do not really appear to be red, green and blue, but are parameters derived from red, green and blue), and use the CIE 1931 XYZ colors matching function to calculate. Two light sources made up of a mixture of different wavelengths of light can exhibit the same color, which is called "metamerism". When two light sources have the same apparent color to a standard observer (CIE 1931 standard chromaticity observer), they have the same tristimulus value, regardless of the spectral distribution of the light that generated them.

Taking a traditional red (R), green (G), and blue (B) three-channel display as an example, the general calibration process is as follows:

a. Put the display in a completely dark environment to avoid the interference of ambient light on the calibration process;

b. Arrange the color measurement sensor. Figure 2 is a schematic diagram of the color sensor measuring the brightness of the display. As shown in Figure 2, the color measurement sensor can be attached to the central surface of the display;

c. Display the R channel according to a certain grayscale interval, and measure the color of the R channel displayed each time to obtain the XYZ tristimulus values; Figure 3 is a schematic diagram of the brightness level, as shown in Figure 3, the display can be from small to large to Display the R channel at a certain grayscale interval, for example, display the R channel with 0, 1, ..., 255;

d. Perform the operation of step c on the G channel, the B channel, the R+B channel, the R+G channel, the B+G channel and the R+G+B channel in turn;

e. Establish the corresponding relationship between RGB electronic signal strength and XYZ tristimulus values. Table 1 shows the brightness levels and corresponding XYZ values displayed by the bit numbers of different channels of the display. As shown in Table 1, RGB can be established in the form of a 3D comparison table. Corresponding relationship between electronic signal strength and XYZ tristimulus value;

Table 1

f. After the above-mentioned comparison table is corrected, when any RGB color is displayed, the 3D comparison table can be called for color display.

Currently, the prior art uses CIE 1931XYZ tristimulus values to define the human eye's response to color. But as mentioned earlier, this response is the average of thousands of normal observers' responses to color, Figure 4 is the tristimulus X spectral response, Figure 5 is the tristimulus Y spectral response, and Figure 6 is the tristimulus Z spectrum Response, as shown in Figure 4, Figure 5, and Figure 6, even for people with normal vision, each person's spectral response to color may vary greatly. For example, with age, the human eye responds to blue. The spectral response is getting weaker and weaker. The difference in perception of color by different human eyes can reach more than 6, (calculated by the CIE-DE2000 color difference formula), and 6 represents a large color difference.

When the monitor performs color correction according to the color perception curve of a standard observer, the displayed colors will make different observers see different colors, especially for very saturated colors, the color perception color difference between different people will further increase .

It can be seen that when the electronic device performs color correction according to the color perception curve of a standard observer, the displayed colors will still cause different observers to see different colors, which cannot solve the problem of color perception color difference between different observers, thereby reducing the The display effect of the electronic device is improved, and at the same time, the individual requirements for color display cannot be met, resulting in poor intelligence of the electronic device.

In order to solve the above problems, the present application proposes a method for establishing a personalized color correction scheme, so that the display can display different RGB values for different observers, and can combine the color responses of different observers, so that they can see the same s color. In some embodiments of the present application, the electronic device may first detect the actual color response of the target observer to obtain corresponding response data, and then use the response data to correct the preset color mapping relationship corresponding to the standard observer, Thereby, the corrected color mapping relationship representing the corresponding relationship between the tristimulus values of the target observer and the RGB values is obtained, and then the personalized color display for the target observer can be realized through the corrected color mapping relationship. It can be seen that the color correction scheme proposed in the present application can solve the problem of color perception color difference between different observers, improve the display effect of the electronic device, meet the individual requirements of color display, and greatly improve the intelligence of the electronic device.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

An embodiment of the present application provides a color correction method. FIG. 7 is a schematic diagram of the first implementation flow of the color correction method. As shown in FIG. 7 , in the embodiment of the present application, the method for performing color correction by an electronic device may include the following steps :

Step 101: Detect response data of the target observer to the reference picture, and generate a color correction instruction based on the response data.

In the embodiment of the present application, the electronic device may first detect the response data of the target observer to the reference picture, and then may generate the color correction instruction based on the response data.

In some embodiments of the present application, after acquiring the detection instruction corresponding to the target observer, the electronic device may respond to the detection instruction and acquire response data corresponding to the target observer according to a preset detection strategy.

It should be noted that, in the embodiments of the present application, the above-mentioned electronic device may be any terminal device configured with a display screen, such as a tablet computer, a mobile phone, an electronic reader, a personal computer (Personal Computer, PC), a notebook computer, Vehicle-mounted equipment, Internet TV, wearable equipment, Personal Digital Assistant (PDA), Portable Media Player (PMP), navigation device, etc.

In some embodiments of the present application, the detection device is configured with a display screen, and the display screen can display colors according to a preset color mapping relationship. The preset color mapping relationship may represent the corresponding relationship between the reference tristimulus values corresponding to the standard observer and RGB.

It can be understood that, in the embodiment of the present application, the electronic device may acquire a detection instruction corresponding to the target observer, where the detection instruction is used to perform personalized detection instructions on the spectral response data corresponding to the target observer.

Exemplarily, in the embodiment of the present application, the electronic device may acquire the detection instruction corresponding to the target observer through the touch operation detected on the display screen. For example, FIG. 8 is the first schematic diagram of acquiring the detection instruction. As shown in FIG. 8 , the electronic device calls out the display interface corresponding to the detection function through the touch operation detected on the display screen, and acquires the detection instruction in the display interface.

Exemplarily, in the embodiment of the present application, the electronic device may also acquire the detection instruction corresponding to the target observer through a preset trigger mechanism. For example, FIG. 9 is a second schematic diagram of acquiring a detection instruction. As shown in FIG. 9 , when the electronic device detects a pressing operation with a pressure greater than a preset threshold on the physical buttons on both sides, the detection function is triggered, that is, the target observer is acquired detection command.

Further, in the embodiment of the present application, after acquiring the detection instruction corresponding to the target observer, the electronic device can detect the color response of the target observer according to the preset detection strategy, so as to obtain the corresponding response of the target observer. data.

It can be understood that, in the embodiment of the present application, the response data of the target observer detected by the electronic device to the reference picture may be spectral response data corresponding to the target observer.

In some embodiments of the present application, the preset detection strategy may be used to detect the actual color response of the target observer in combination with the Gamma value of the display screen in the electronic device.

Among them, the tristimulus value is the amount of three primary color stimuli required to match the color of the avenue to be measured in the three-color system, which can be represented by XYZ, X is the red primary color stimulus, Y is the green primary color stimulus, Z For the blue primary color stimulus. In the red, green and blue three primary color system, the stimulus amount of red, green and blue can be represented by R, G, and B respectively. Since the three primary colors of red, green and blue selected from the actual spectrum cannot be mixed with all the colors that exist in nature, CIE It is assumed that there are three primary colors in nature, that is, the theoretical three primary colors, which are represented by XYZ, in order to theoretically mix colors together, thus forming the XYZ color measurement system.

Further, in the embodiment of the present application, the reference tristimulus value corresponding to the standard observer may be expressed as XYZ, and the tristimulus value corresponding to the target observer may be expressed as (XYZ)′.

Further, in the embodiment of the present application, after detecting the response data of the target observer to the reference picture, the electronic device may further generate a color correction instruction based on the response data.

It can be understood that, in the embodiment of the present application, if the response data corresponding to the target observer is different from the reference color response data corresponding to the standard observer, the electronic device can adjust the preset color mapping relationship. In some embodiments of the present application, the electronic device may start the correction process of color display by receiving a color correction instruction corresponding to the target observer. That is, the color correction instruction can be used as an instruction to perform personalized adjustment processing of color display for the target observer.

Further, in the embodiment of the present application, before the electronic device generates the color correction instruction based on the response data, the method for performing color display by the electronic device may further include the following steps:

Step 104: Generate a detection result according to the response data and the reference color response data.

Step 105, displaying the detection result.

In the embodiment of the present application, after completing the color response detection of the target observer and obtaining the response data corresponding to the target observer, the electronic device can respond to the color detection result according to the response data and the reference color data corresponding to the standard observer, and then The detection result can be displayed.

It can be understood that, in the embodiment of the present application, after the electronic device completes the detection of the color response of the target observer, the detection result can be generated by using the response data and the reference color response data, that is, the electronic device can pass the detection result. Indicates the difference and difference between the response data and the reference color response data, so that after the detection results are displayed, the target observer can more intuitively understand their own personalized needs.

It should be noted that, in the embodiments of the present application, the form of the detection result generated by the electronic device may include various forms such as graphics and tables, which are not specifically limited in the present application.

Exemplarily, in the present application, FIG. 10 is a schematic diagram of the detection result. As shown in FIG. 10 , the detection result generated by the electronic device according to the response data and the reference color response data may be a comparison diagram of different colors. It is more intuitive to reflect the difference between the response data of the target observer and the reference color response data of the standard observer.

That is to say, in the embodiment of the present application, after detecting the response data of the target observer to the reference picture, the electronic device may directly obtain the correction instruction corresponding to the target observer, or may first respond to the data based on the response data and the reference color. Generate and display the detection results, and then obtain the correction instructions corresponding to the target observer.

Exemplarily, in the embodiment of the present application, the electronic device may acquire the correction instruction corresponding to the target observer through a touch operation detected on the display screen. For example, FIG. 11 is a schematic diagram 1 of obtaining a calibration instruction. As shown in FIG. 11 , the electronic device calls out the display interface corresponding to the calibration function through a touch operation detected on the display screen, and obtains the calibration instruction in the display interface.

Exemplarily, in the embodiment of the present application, the electronic device may also acquire the correction instruction corresponding to the target observer through a preset trigger mechanism. For example, FIG. 12 is the second schematic diagram of obtaining the correction instruction. As shown in FIG. 12 , when the electronic device corrects the pressing operation with the pressure greater than the preset threshold on the physical buttons on both sides, the correction function is triggered, that is, the target observer is obtained. correction command.

Step 102: In response to the color correction instruction, perform correction processing on the preset color mapping relationship based on the response data, and obtain the corrected color mapping relationship.

In the embodiment of the present application, after generating the color correction instruction based on the response data, the electronic device may respond to the color correction instruction, and perform correction processing on the preset color mapping relationship based on the response data, so as to obtain the corrected color mapping relationship .

It can be understood that, in the embodiments of the present application, before the calibration is performed, the electronic device displays colors according to a preset color mapping relationship, wherein the preset color mapping relationship can be used for the reference corresponding to the standard observer. The corresponding relationship between the tristimulus values and the RGB values is determined, that is, the reference color response data is the standard spectral response data corresponding to the standard observer; correspondingly, the preset color mapping relationship is the reference three corresponding to the standard observer. Correspondence between stimulus values and RGB values.

Further, in the embodiment of the present application, if the response of the target observer and the standard observer to the color is different, then when the electronic device continues to display the color according to the preset color mapping relationship, the color seen by the target observer will be the same. There will be errors, so personalized correction of the color display for the target observer is required. In some embodiments of the present application, the electronic device can correct the preset color mapping relationship according to the response data corresponding to the target observer, that is, change the corresponding relationship between the reference tristimulus value and the RGB value, and finally obtain the corrected color Mapping relations.

It can be understood that, in the present application, the corrected color mapping relationship can be used to determine the correspondence between the tristimulus values corresponding to the target observer and the RGB values. That is to say, the response data is the spectral response data corresponding to the target observer; correspondingly, the corrected color mapping relationship is the corresponding relationship between the tristimulus values corresponding to the target observer and the RGB values.

Further, in the embodiment of the present application, the electronic device performs correction processing on the preset color mapping relationship based on the response data, and the method for obtaining the corrected color mapping relationship may include the following steps:

Step 102a: Determine a correction matrix according to the response data and the reference color response data.

In the embodiment of the present application, the electronic device may first determine a correction matrix according to the response data and the reference color response data, wherein the correction matrix is used to convert the reference color response data into response data, and the response data is the target observation data The spectral response data corresponding to the observer; the reference color response data is the standard spectral response data corresponding to the standard observer.

Exemplarily, in this application, the conversion between the spectral response data corresponding to the standard observer and the standard spectral response data corresponding to the target observer may be implemented by a 3×3 conversion matrix. In some embodiments of the present application, the standard spectral response data of a standard observer can be expressed as

The spectral response data corresponding to the target observer can be expressed as

Then, when using the transformation matrix for transformation, the following formula can be used:

where the transformation matrix can be expressed as

It can be known from the above formula (1) that the conversion matrix can be obtained by calculating the value of a _ij (i, j=1, 2, 3) in the conversion matrix.

Step 102b: Based on the calibration matrix, establish a conversion relationship between the tristimulus values corresponding to the target observer and the reference tristimulus values corresponding to the standard observer.

In the embodiment of the present application, after determining the correction matrix according to the response data and the reference color response data, the electronic device can use the correction matrix to establish the tristimulus value corresponding to the target observer and the standard observer. Refer to the conversion relationship between tristimulus values.

Further, in the embodiment of the present application, after the conversion matrix is obtained by calculation, the difference between the reference tristimulus value XYZ corresponding to the standard observer and the tristimulus value (XYZ)' corresponding to the target observer can be determined based on the conversion matrix. The conversion relationship is expressed as the following formula:

Among them, the reference tristimulus value XYZ can be expressed as

The tristimulus values (XYZ)' corresponding to the target observer can be expressed as

Step 102c: Determine the corrected color mapping relationship based on the conversion relationship and the preset color mapping relationship.

In the embodiment of the present application, after completing the conversion relationship between the tristimulus value corresponding to the target observer and the reference tristimulus value, the electronic device can use the conversion relationship and the preset color mapping relationship to further determine the corrected value Color mapping relationship.

It can be understood that, in the embodiment of the present application, the preset color mapping relationship is pre-stored by the electronic device and used to determine the corresponding relationship between the reference tristimulus values and the RGB values. Therefore, when establishing the target observation On the basis of the conversion relationship between the corresponding tristimulus value and the reference tristimulus value, the electronic device can complete the correction of the color display, and convert the preset color mapping relationship into the corrected color mapping relationship, wherein the color mapping relationship uses The corresponding relationship between the tristimulus values corresponding to the target observer and the RGB values is determined.

FIG. 13 is a schematic diagram of color display calibration. As shown in FIG. 13 , the corresponding relationship between the RGB values of the electronic device and the reference tristimulus values corresponding to the standard observer is the preset color mapping relationship. After the conversion relationship between the corresponding tristimulus value and the reference tristimulus value is established, the corresponding relationship between the tristimulus value corresponding to the target observer and the RGB value of the electronic device can be further obtained based on the conversion relationship, that is, the corrected color can be obtained. Mapping relations.

It should be noted that, in the embodiments of the present application, the reference color response data and the preset color mapping relationship are all pre-stored by the electronic device.

Further, in the embodiment of the present application, after the correction matrix is determined according to the response data and the reference color response data, that is, after step 103a, the method for performing color display by the electronic device may further include the following steps:

Step 102d: If the correction matrix satisfies the preset correction condition, perform correction processing on the preset color mapping relationship according to the correction matrix, and obtain the corrected color mapping relationship.

Step 102e: If the calibration matrix does not meet the preset calibration condition, directly determine the preset color mapping relationship as the corrected color mapping relationship.

In the embodiment of the present application, after calculating the conversion matrix between the response data and the reference color response data, the electronic device may first determine whether correction processing is required, and then perform the next processing according to the determination result.

In some embodiments of the present application, the electronic device can determine the degree of deviation between the response data and the reference color response data through the transformation matrix, that is, the difference in the color response between the target observer and the standard observer. If the deviation between the reference color response data is large, the electronic device may consider that the display effect will be reduced, so it is determined that correction processing is required; if the deviation between the response data and the reference color response data is small enough, the electronic device may consider that It will not affect the display effect, so it is determined that correction processing is not required.

Exemplarily, in this application, the electronic device may preset a calibration condition, that is, a preset calibration condition, and if the calibration matrix satisfies the preset calibration condition, it is determined to perform calibration processing, and then the calibration process can be performed according to the calibration matrix. The preset color mapping relationship is corrected, and the corrected color mapping relationship is obtained. For example, the methods of the above steps 102b and 103c are performed to perform the correction; The electronic device may directly determine the preset color mapping relationship as the corrected color mapping relationship, that is, continue to perform color display according to the preset color mapping relationship.

Further, in the embodiment of the present application, FIG. 14 is a schematic diagram 2 of the implementation flow of the color correction method. As shown in FIG. 14 , after detecting the response data of the target observer to the reference picture, and generating a color correction instruction based on the response data, That is, after step 101, and in response to the color correction instruction, the preset color mapping relationship is corrected based on the response data, and before the corrected color mapping relationship is obtained, that is, before step 102, the method for performing color display by the electronic device may further include the following steps :

Step 106: Determine a deviation parameter between the response data and the reference color response data.

Step 107: If the deviation parameter is greater than the preset deviation threshold, perform correction processing.

In the embodiment of the present application, after detecting the response data of the target observer to the reference picture, the electronic device may compare the response data with the pre-stored reference color response data, calculate and obtain the deviation parameter between the two, and then according to The deviation parameter judges whether correction of color display is required.

Further, in the embodiment of the present application, the deviation parameter can determine the degree of deviation between the response data and the reference color response data, that is, the deviation parameter can determine the difference between the target observer and the standard observer on the color. Response gaps are determined.

It can be understood that, in the embodiment of the present application, the electronic device presets a threshold value to determine whether the correction process needs to be determined. In some embodiments of the present application, the electronic device can compare the deviation parameter between the calculated response data and the reference color response data with a preset deviation threshold, and if the comparison result is that the deviation parameter is greater than the preset deviation threshold, it can It is considered that for the target observer, the display effect of color display according to the original preset color mapping relationship is not ideal, so it is determined that correction processing is required; if the comparison result is that the deviation parameter is less than or equal to the preset deviation threshold, according to the original Some preset color mapping relationships for color display will not reduce the effect for the target observer, so it is determined that correction processing is not required.

That is to say, in the present application, when the electronic device performs the correction process for color display, it may first detect the correction instruction corresponding to the target observer, and then respond to the correction instruction, based on the response data corresponding to the target observer. The original preset color mapping relationship is adjusted to obtain the corrected color mapping relationship, so as to complete the correction processing.

Correspondingly, in this application, when the electronic device performs the correction process for color display, it can also directly determine whether to perform the correction process according to the obtained response data corresponding to the target observer. For calibration, the original preset color mapping relationship is adjusted based on the response data corresponding to the target observer, and the corrected color mapping relationship is obtained to complete the calibration process.

Step 103: Perform color correction processing on the image according to the corrected color mapping relationship to provide a color corrected image.

In the embodiment of the present application, after the electronic device responds to the color correction instruction, performs correction processing on the preset color mapping relationship based on the response data, and obtains the corrected color mapping relationship, it can adjust the color mapping relationship according to the corrected color mapping relationship. The image is color-corrected to provide a color-corrected image to complete the personalized color display for the target observer.

It should be noted that, in the embodiment of the present application, the electronic device first performs color display processing according to the preset color mapping relationship corresponding to the standard observer, and after completing the acquisition of the response data for the target observer, the electronic device can use The response data completes the conversion of the preset color mapping relationship, obtains the corrected color mapping relationship corresponding to the target observer, and then performs color correction processing on the image according to the corrected color mapping relationship to provide the color-corrected image, thus completing the Correction processing of color display for target observers.

That is, in the present application, before performing color correction processing on an image according to the corrected color mapping relationship and providing a color corrected image, the electronic device displays colors according to the preset color mapping relationship.

In some embodiments of the present application, when the electronic device performs color correction processing on the image according to the corrected color mapping relationship and provides a color corrected image, it can first determine the initial RGB values corresponding to the image; and then according to the corrected color mapping The relationship and the initial RGB value are used to determine the target tristimulus value; finally, the display driving voltage can be adjusted according to the target tristimulus value, thereby obtaining a color-corrected image.

In some embodiments of the present application, when the electronic device displays an image, it may first determine the RGB value of the image itself, that is, the initial RGB value, and then use the corrected color mapping relationship corresponding to the target observer to determine the initial RGB value The tristimulus value corresponding to the value is the target tristimulus value. Based on the correspondence between the RGB electronic signal strength and the XYZ tristimulus values shown in Table 1 above, the brightness level displayed by the number of bits of different channels corresponding to the target tristimulus values can be further determined.
