Abstract
An image processing method and apparatus are disclosed, to improve quality of an image on which color processing is performed. The method includes: determining color values of N color components of each pixel of a to-be-processed image, where N is a natural number greater than 1; determining N ratios of a luminance value of each pixel to the color values of the N color components; determining N first color adjustment coefficients based on the N ratios; and performing color processing on each pixel based on the N first color adjustment coefficients and the color values of the N color components to obtain a target image.
