Abstract: This application provides an image processing method and apparatus, a device, and a computer-readable storage medium for use in the field of computer vision. The image processing method includes the following steps: a first image device obtains a compressed image of a raw image and decompresses the compressed image to obtain a first decompressed image; the first image device determines target difference information based on difference information between the raw image and the first decompressed image; the first image device further compresses the target difference information to obtain compressed target difference information; and the first image device sends the compressed image and the compressed target difference information to a second image device. The second image device restores an image based on the received compressed image and target difference information. This application reduces a precision loss between the image restored by the second image device and the raw image.
