Claim 9:
10. An image encoding method performed by an encoding apparatus, the method comprising:
generating luma prediction samples of a current block in a current picture;
deriving reshaper model indices for reshaping on the luma prediction samples;
generating reshaped luma prediction samples based on the luma prediction samples and the reshaper model indices;
generating reshaping related information; and
encoding image information including prediction mode information for generating the luma prediction samples and the reshaping related information,
wherein the image information includes an 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.
