Claim 3:
4. The method of claim 3, before creating the candidate list corresponding to the coding mode for the coding mode used for the coding block in the original picture, further comprising:
when the reference frame corresponding to the coding block is the original picture and the coding block is coded by Intra Block Copy (IBC) with Affine (IBCAffine), determining that the coding mode used for the coding block is the first affine motion mode, and setting a value of a merge flag Merge_Flag of the coding block to a first value; and
when the reference frame corresponding to the coding block is the original picture and the coding block is coded by IBC with Affine Merge (IBCAffineMerge), determining that the coding mode used for the coding block is the second affine motion mode, and setting the value of the merge flag Merge_Flag of the coding block to a second value, the first value being different from the second value.
