Classification: CPC H | IPC H

Claim 7:
8. An image encoding method performed by an encoding apparatus, the method comprising:
determining whether or not lossless coding is used for a current block;
generating prediction information on the current block based on a result of the determination;
generating residual information on the current block based on the result of the determination; and
encoding image information including at least one of the prediction information, the residual information and information on whether or not the lossless coding is used,
wherein based on the determination that the lossless coding is used for the current block, an Intra Sub-Partitions (ISP), a luma dependent chroma residual scaling, a luma mapping with chroma scaling (LMCS), a Decoder-side motion vector refinement (DMVR), a Bi-directional optical flow (BDOF), and a prediction refinement with optical flow (PROF) are not applied to the current block.
