Claim 14:
15. A non-transitory computer-readable storage medium, wherein the computer-readable storage medium stores computer program instructions; and when the computer program instructions are run on a computer, the computer is enabled to perform:
obtaining encoded information of a coding block in a video stream, wherein the coding block belongs to an image frame in the video stream; one image frame in the video stream comprises a plurality of coding blocks; the encoded information comprises a reference image frame index, a matched coding block index, and an inter-frame prediction marker; and a matched coding block identified by the matched coding block index is a coding block that is in a reference image frame identified by the reference image frame index and that has a minimum pixel difference from the coding block;
determining an inter-frame prediction mode of the coding block based on the inter-frame prediction marker, and determining a super-resolution pixel block of the coding block based on the inter-frame prediction mode and pixel information of the matched coding block, wherein the super-resolution pixel block is a pixel block obtained after a super-resolution processing is performed on pixel information of the coding block; and
stitching super-resolution pixel blocks of coding blocks that belong to a same image frame in the video stream to obtain a super-resolution image, wherein the super-resolution image is used for generating a super-resolution video.
