Claim 14:
15. The encoder of claim 12, wherein when the prediction mode is an intra block copy, IBC, mode, constructing a motion information candidate list corresponding to the current image block, comprises:
checking each spatial candidate block of the current image block in the checking order to obtain available spatial candidate motion information, and adding the obtained spatial candidate motion information into the motion information candidate list;
if a number of pieces of candidate motion information in the motion information candidate list is insufficient, constructing a motion information list of coded/decoded blocks based on motion information of the coded/decoded blocks, and obtaining motion information from the motion information list of the coded/decoded blocks and adding the obtained motion information as candidate motion information into the motion information candidate list; and/or
if a number of pieces of candidate motion information in the motion information candidate list is still insufficient, filling the motion information candidate list with default motion information.
