Therefore, in the present embodiment, the pre-acquired reference coordinates need to be set, the pre-acquired reference coordinates can be set to (0.33 ), and the actually acquired screen color coordinates are (0.321, 0.329), and there is a deviation therebetween, so that the present embodiment needs to debug the actually acquired screen color coordinates (0.321, 0.329) to generate the debugging parameters, where the debugging parameters are parameters when the color coordinates (0.321, 0.329) are debugged to be the reference coordinates (0.33 ). In practical applications, the pre-acquired reference coordinate may be other coordinate values, and may be determined according to actual display requirements, and the embodiment is not limited specifically, and the above specific numerical values are only used to explain specific details of the embodiment, and do not limit the embodiment.

In the prior art, when a picture is displayed on a screen, the screen has manufacturing errors, and the display effects of screens with different specifications can deviate. Therefore, in the embodiment, the color coordinates of the screen are firstly acquired, the debugging parameters are generated based on the difference between the color coordinates and the reference coordinates, and when the screen is displayed, the debugging parameters can debug the color coordinates into the reference coordinates, so that the display effects of the screens with different specifications can be consistent.

In practical applications, the plurality of display areas may be divided in a matrix manner, however, in this embodiment, the dividing manner of the plurality of display areas is not limited, and in this embodiment, the plurality of display areas may be divided according to actual display needs.
Specifically, after acquiring the color coordinates of each display area, generating debugging parameters corresponding to the color coordinates, wherein the debugging parameters need to be determined according to pre-acquired reference coordinates; it should be noted that, in practical applications, the debugging parameter should be a set of data, and the corresponding color coordinate can be debugged to be the reference coordinate. That is, the debugging parameters and the color coordinates are in a one-to-one correspondence relationship, and the debugging parameters can only be applied to the corresponding color coordinates.
In practical application, when a picture needs to be displayed on a screen, the debugging parameters are applied to the corresponding color coordinates, the corresponding color coordinates are debugged into reference coordinates, and the picture is displayed in a screen display area corresponding to the color coordinates.
In this embodiment, the color coordinates of each display area are obtained, and the debugging parameters corresponding to each color rendering area are generated, so that the debugging accuracy is further improved.
A third embodiment of the present invention relates to a debugging method. The third embodiment is substantially the same as the second embodiment, with the main differences being: in the third embodiment of the present invention, after acquiring the color coordinates of each display area, the method further includes: and searching a marginal color coordinate, a typical color coordinate and a common color coordinate in the plurality of color coordinates. In addition, those skilled in the art can understand that this embodiment is a further refinement of the second embodiment, and the specific details of the second embodiment are still valid in this embodiment, and are not described herein again to avoid repetition.
The flowchart of the debugging method of the embodiment is shown in fig. 3, and specifically includes the following steps:
Specifically, after acquiring the color coordinates of each display area, searching a marginal color coordinate, a typical color coordinate and a common color coordinate in a plurality of color coordinates; wherein, any parameter of the marginal color coordinate is the upper limit value or the lower limit value of the standard value of the color coordinate in the standard deviation range, and the typical color coordinate is the standard value of the color coordinate; the normal color coordinates are color coordinates other than the borderline color coordinates and the typical color coordinates among the plurality of color coordinates.
For example, the standard value of the white color coordinate of the screen is (0.33 ), the standard error range is ± 0.003, that is, the first parameter of the white color coordinate of the screen is within a range of 0.327 to 0.333, the second parameter is within a range of 0.327 to 0.333, and any one of the marginal color coordinates is a coordinate having a standard value within an upper limit value or a lower limit value of the standard deviation range, for example, the first parameter is a coordinate having a first value of 0.327 or 0.333, the second parameter is a coordinate having a second value of 0.327 to 0.333, or the second parameter is a coordinate having a second value of 0.327 or 0.333, the first parameter is a coordinate having a first value of 0.327 to 0.333, and the typical color coordinate is a standard value of the white color coordinate, that is (0.33 ), and the normal color coordinate is a color coordinate excluding the edge color coordinate and the typical color coordinate.

Specifically, the mode of generating the tuning parameters corresponding to the normal color coordinates is different from the mode of generating the tuning parameters corresponding to the border color coordinates and the typical color coordinates. Debugging parameters corresponding to the marginal color coordinates and debugging parameters corresponding to the typical color coordinates can be directly obtained through calculation of the processor; the obtaining mode of the debugging parameters of the common color coordinates is as follows: marking positions of a marginal color coordinate and a typical color coordinate in a chromaticity diagram coordinate system, marking the position of the common color coordinate in the chromaticity diagram coordinate system after the value of the common color coordinate is determined, and searching a target color coordinate closest to the common color coordinate in the marginal color coordinate and the typical color coordinate, wherein the target color coordinate is one of the marginal color coordinate and the typical color coordinate; after the target color coordinate is determined, the debugging parameters corresponding to the target color coordinate and the debugging parameters corresponding to the common color coordinate are determined.
It should be noted that, because the pressure of obtaining the debugging parameter calculation is large, the pressure of calculating the color coordinate distance is small; therefore, the embodiment obtains debugging parameters of all color coordinates by obtaining debugging parameters of the marginal color coordinates and the typical color coordinates, thereby reducing the calculation pressure of the processor.
In one example, the same color coordinates may be set as a set of color coordinate modules before the marginal color coordinates, the representative color coordinates, and the normal color coordinates are found in the plurality of color coordinates. After the same color coordinates are set as a set of color coordinate modules, a marginal color coordinate module, a typical color coordinate module and a common color coordinate module are searched in the plurality of color coordinate modules. By the method, the same color coordinates are divided into the modules, and the debugging parameters corresponding to all the color coordinates can be obtained only by calculating the debugging parameters corresponding to the marginal color coordinate module and the typical color coordinate module, so that the calculation pressure can be further reduced.
A fourth embodiment of the present invention relates to a debugging method. The fourth embodiment is substantially the same as the second embodiment, with the main differences being: in the fourth embodiment of the present invention, after acquiring the color coordinates of each region, the method further includes: the same color coordinates are set as a set of color coordinate modules. In addition, those skilled in the art can understand that this embodiment is a further refinement of the second embodiment, and the specific details of the second embodiment are still valid in this embodiment, and are not described herein again to avoid repetition.
The flowchart of the debugging method of the embodiment is shown in fig. 4, and specifically includes the following steps:
And 403, generating debugging parameters corresponding to each set of color coordinate modules.
In this embodiment, the same color coordinates are summarized into a set of color coordinate modules, and since the set of color coordinate modules is only debugged once, the calculation burden of the camera module in the debugging process can be reduced, thereby improving the speed of the debugging process. In practical application, when a picture needs to be displayed on a screen, the debugging parameters are applied to the corresponding color coordinates, the corresponding color coordinates are debugged into reference coordinates, and the picture is displayed in a screen display area corresponding to the color coordinates.
