Abstract: A deblocking filtering control involves deciding whether to apply deblocking filtering to sample values in a sample block in a picture and in a neighboring sample block in the picture based on i) whether illumination compensation is enabled for sample prediction values in a first prediction block in a reference picture for said sample block and/or ii) whether illumination compensation is enabled for sample prediction values in a second prediction block in said reference picture or another reference picture for said neighboring sample block. The sample block and the neighboring sample block are separated in the picture by a block boundary. This decision to apply deblocking filtering based on whether illumination compensation is enabled reduces blocking artefacts that may otherwise arise in certain pictures of a video sequence.
