Abstract
An image decoding method is disclosed in the present specification. An image decoding method according to the present invention may include: determining a prediction mode of a current block as IBC (Intra Block Copy) mode, deriving a candidate list for deriving a block vector of the current block and deriving a block vector of the current block by using the candidate list, wherein the candidate list is derived based on a size of the current block.
Claims20
A decoding method, comprising:
- determining a prediction mode for a current block;
- generating a prediction block by performing a prediction according to the prediction mode;
- and
- generating a reconstructed block using the prediction block.
An encoding method, comprising:
- determining a prediction mode for a current block;
- generating a prediction block by performing a prediction according to the prediction mode;
- and
