1. An image enhancement method, performed by a network device, comprising:
obtaining an original image;
performing synthesis processing on features of the original image to obtain a first illumination map corresponding to the original image, a resolution of the first illumination map being lower than a resolution of the original image;
obtaining, based on the first illumination map, a mapping relationship between an image and an illumination map;
generating a second illumination map from the original image based on the mapping relationship, a resolution of the second illumination map being equal to the resolution of the original image; and
performing image enhancement processing on the original image according to the second illumination map to obtain a target image.
