Classification: CPC H | IPC H

Claim 0:
1. An image decoding method performed by a decoding apparatus, the method comprising:
receiving image information through a bitstream;
generating luma prediction samples of a current block based on the image information; and
performing a reshaping process for the luma prediction samples,
wherein the performing the reshaping process includes:
deriving reshaper model indices for the reshaping; and
generating reshaped luma prediction samples based on the luma prediction samples and the reshaper model indices,
wherein the image information includes adaptation parameter set (APS),
wherein the APS includes reshaper model field,
wherein a reshaper model is derived based on the reshaper model field,
wherein the reshaper model indices are derived based on the reshaper model.
