Classification: CPC H | IPC H

Claim 1:
2. An image decoding apparatus comprising at least one processor configured to
when a prediction mode of a first coding unit is a combined inter-intra prediction mode, to determine a first prediction block of the first coding unit by using a weighted sum of a first sample value according to intra-prediction and a second sample value according to inter-prediction,
when the prediction mode of the first coding unit is the combined inter-intra prediction mode, to determine a value of a boundary filtering strength applied to a boundary between a first reconstruction block and a second reconstruction block, wherein the value of the boundary filtering strength is equal to a value of a boundary filtering strength used when the prediction mode of the first coding unit is an intra prediction mode, and
to perform deblocking filtering on samples adjacent to the boundary based on the determined value of the boundary filtering strength,
wherein the first coding unit and a second coding unit are obtained by splitting an upper coding unit.
