IMAGE COLOR PROCESSING METHOD AND APPARATUS

WIPO Patent Application WO/2021/217647

A1

Provided are an image color processing method and apparatus. The method comprises: determining color values of a plurality of color components of a pixel of an image to be subjected to processing (S301); respectively determining the ratios of a brightness value of the pixel to the color values of the plurality of color components (S302); determining a first color adjustment coefficient of the pixel according to the ratios and a first lookup table (S303); and performing color processing on the pixel according to the first color adjustment coefficient, so as to obtain a target image (S304). Accordingly, the color deviation phenomenon of an image subjected to color processing can be reduced, and the quality of the image subjected to color processing is improved. Each step can be implemented by means of a hardware circuit of a terminal device, for example, the processing of integer data can be implemented by means of determining the first color adjustment coefficient by means of the first lookup table, such that the execution process of an image color processing procedure can be implemented into the hardware circuit, and the practical application possibilities of the image color processing method can be increased.
