Image processing method and apparatus, computer device, and storage medium

An image processing method, further comprising:

• generating a first image by performing format conversion on an original image, the original image being represented by a first color representation, the first image being represented by a second color representation, and an image dynamic range supported by the second color representation being wider than an image dynamic range supported by the first color representation;
• acquiring a second image that is based on the original image, the second image being represented by the second color representation, and an image dynamic range of the second image being wider than an image dynamic range of the original image;
• determining a first image area from a source image, the source image being one of the first image and the second image;
• determining a second image area from a destination image according to a position of the first image area in the source image, the destination image being another one of the first image and the second image;
• smoothing an original weight value of each pixel of a plurality of pixels in the destination image, to obtain target weight values of the plurality of pixels in the destination image;
• and
• generating a fusion image corresponding to the original image based on the destination image, the source image, and the target weight values of the plurality of pixels in the destination image.

An image processing apparatus, comprising:

• processing circuitry configured to:
• for each video image of a plurality of video images of an original video,
• acquire a first image generated by format conversion of the respective video image, the respective video image being represented by a first color representation, the first image being represented by a second color representation, an image dynamic range supported by the second color representation being wider than an image dynamic range supported by the first color representation, and an image dynamic range of the first image being the same as an image dynamic range of the respective video image,
• acquire a second image that is based on the respective video image, the second image being represented by the second color representation, and an image dynamic range of the second image being wider than the image dynamic range of the respective video image,
• determine a fusion weight value of each pixel of a plurality of pixels in a target image according to a display order of the respective video image in the original video, the target image being one of the first image and the second image,
• generate a fusion weight map based on the fusion weight value of each pixel of the plurality of pixels in the target image, and
• generate a fusion image corresponding to the respective video image based on the target image, a base image, and the fusion weight map, the base image being another one of the first image and the second image;
• and
• generate a fusion video based on the fusion images corresponding to the plurality of video images.
