Classification: CPC H | IPC H

Claim 4:
5. A non-transitory computer-readable digital storage medium for storing encoded image information generated by a method, the method comprising:
deriving whether a matrix-based intra prediction (MIP) is applied to a current block;
generating intra prediction samples for the current block based on a determination that the MIP is applied to the current block;
generating residual samples for the current block based on the intra prediction samples; and
encoding image information including flag information on the MIP and information on the residual sample,
wherein a matrix for the MIP is derived based on a width and a height of the current block,
wherein the intra prediction samples are generated based on the matrix,
wherein the image information includes MIP mode information based on the flag information on the MIP,
wherein the matrix is derived further based on the MIP mode information,
wherein for the current block with a size of 32×4 in which a ratio of the width and the height of the current block is larger than four, the flag information on the MIP is included in the image information, and
wherein based on a value of the flag information on the MIP being equal to 1, it is determined that the MIP is applied to the current block with the size of 32×4 in which the ratio of the width and the height of the current block is larger than four.
