[ first embodiment ]
Referring to fig. 1, fig. 1 is a flowchart of a display screen correction method according to a first embodiment of the present application. The display screen correction method comprises the following steps:
step S1, obtaining brightness data of a target display screen; specifically, the method comprises the steps of adjusting equipment parameters of an acquisition equipment to obtain first shooting parameters, wherein the acquisition equipment is used for measuring brightness and chrominance values, the equipment parameters comprise exposure time and brightness, and specifically, the first shooting parameters are obtained through the selection of the acquisition equipment by a user and the adjustment of the equipment parameters; acquiring a first acquired image of the target display screen, such as an LED display screen, when displaying a target picture by using the acquisition device based on the first shooting parameters, wherein the image information, such as hue information, brightness information and saturation information, of the first acquired image acquired by the acquisition device can be normal by adjusting the acquisition device through the first shooting parameters, namely the information is positioned in an image information acquisition range which can be acquired by the acquisition device based on the first shooting parameters, so that acquisition precision is improved; acquiring the brightness data of the target display screen based on the first acquired image;
step S2, calculating a brightness correction coefficient of the target display screen according to set target brightness data such as a brightness attenuation ratio and the brightness data, wherein the target brightness data can also be a specific brightness value after sacrificing brightness, for example, the brightness before correction is 100, and the brightness after correction is set to 80; the brightness correction coefficient of the target display screen is, for example, the brightness correction coefficient of each pixel point in the target display screen, that is, for the whole target display screen, the brightness correction coefficient includes a plurality of brightness correction coefficients, and one brightness correction coefficient is the brightness correction coefficient for one pixel point in the target display screen;
s3, carrying out brightness correction on the target display screen according to the brightness correction coefficient;
step S4, obtaining chromaticity data of the target display screen after brightness correction, wherein the chromaticity data can be represented by means of chromaticity representation such as color coordinates, wavelength, tristimulus values and the like, and the chromaticity representation is not limited herein;
step S5, calculating a chromaticity correction coefficient of the target display screen after brightness correction according to the set target chromaticity data and the chromaticity data, wherein the chromaticity correction coefficient is only a coefficient when correcting the color; the chromaticity correction coefficient mentioned herein is, for example, a chromaticity correction coefficient of each pixel point in the target display screen, and the chromaticity of each pixel point in the target display screen is adjusted by the chromaticity correction coefficient so that each pixel point can display the same chromaticity, thereby solving the problem of color blocks and achieving chromaticity correction; and
