Title:
IMAGE ENCODING/DECODING METHOD AND APPARATUS, AND RECORDING MEDIUM STORING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2020/184922
Kind Code:
A1
Abstract:
An image encoding/decoding method and apparatus is provided. An image decoding method according to the present invention may comprise the steps of: comparing block vector information included in a history-based candidate list with a block vector of a neighboring block, used as an intra block copy (IBC) block vector candidate for IBC prediction of a current block; and adding the block vector information included in the history-based candidate list to an IBC block vector candidate list on the basis of the comparison, wherein the step of comparison is performed for only a candidate included finally in the history-based candidate list.
