1. A method for image encoding, comprising:
obtaining first coding information for a first coding unit in a first image, the first coding information indicating a scheme for encoding the first coding unit into a first bitstream of the first image;
determining, based on a relative position relationship between a target region in a second image obtained from the first image and a second coding unit in the second image, a reuse mode for the second coding unit regarding the first coding information, the second coding unit corresponding to the first coding unit, the target region indicating a region in the second image that is different from the first image;
determining second coding information for the second coding unit based on the reuse mode; and
generating a second bitstream for the second image based on the second coding information.
