Embodiment 1
[0062] see figure 1 Shown, a kind of image color adjustment method of the present invention comprises:
[0063] S101, acquire the input original image, and acquire the RGB value of each pixel in the original image;
[0064] S102. If the brightness and contrast parameters of the original image are adjusted, obtain adjusted brightness and contrast parameters, and obtain a first color matrix based on the adjusted brightness and contrast parameters;
[0065] S103, if the saturation parameter of the original image is adjusted, obtain the adjusted saturation parameter, and obtain a second color matrix based on the adjusted saturation parameter;
[0066] S104. If the picture color temperature parameter of the original image is adjusted, obtain the adjusted picture color temperature parameter, and obtain a third color matrix based on the adjusted picture color temperature parameter;
[0067] S105, if two or more of the brightness and contrast parameters, saturation parameters, and p...
Embodiment 2
[0166] The difference between this embodiment and the first embodiment is that only one of the parameters of brightness and contrast, saturation and picture color temperature is adjusted.
[0167] Specifically, see Figure 7 As shown, assuming that only the brightness and contrast parameters are adjusted (only the saturation parameter and the picture color temperature parameter are adjusted similarly), for example, the image color adjustment method includes:
[0168] S701, acquire the input original image, and acquire the RGB value of each pixel in the original image;
[0169] S702. Acquire adjusted brightness and contrast parameters, and obtain a first color matrix based on the adjusted brightness and contrast parameters;
[0170] S703, converting the first color matrix into a fifth color matrix corresponding to the operating system;
[0171] S704. Obtain a new RGB value based on the RGB value of the original pixel and the fifth color matrix.
[0172] Further, after obtain...

Abstract
The invention discloses an image color adjusting method and system, and the method comprises the steps: obtaining an input original image, and obtaining the RGB value of each pixel point in the original image; obtaining a first color matrix based on the adjusted brightness and contrast parameters; obtaining a second color matrix based on the adjusted saturation parameter; obtaining a third color matrix based on the adjusted picture color temperature parameter; performing superposition processing on the first color matrix, the second color matrix and the third color matrix to obtain a fourth color matrix; converting the fourth color matrix into a fifth color matrix corresponding to the operating system; and generating a new image based on the RGB values of the original pixels and the fifth color matrix. According to the method and the system, the phenomenon that the display effects of the same work are inconsistent due to display equipment difference and / or operating system difference can be eliminated or weakened, and a real image is restored.
Description
technical field [0001] The invention relates to the technical field of image processing and the field of screen display, in particular to an image color adjustment method and system. Background technique [0002] Due to the differences in production technology and materials, there will be inconsistencies in the display effect of the terminal screen (for example, the effect of the same image on different display screens is different), and because the parameters such as brightness and color temperature of the display screen are different from those of the original film. There are certain differences in brightness and color temperature, which will also cause differences between the displayed effect and the original color, and these differences will have a greater impact on some usage scenarios. For example: art teaching, art teaching in art, art and other industries, and color-related industries require that the color effect of the image displayed on the display screen be highl...
