Claim 8:
9. An encoding apparatus for image encoding, the encoding apparatus comprising:
a memory; and
at least one processor connected to the memory, the at least one processor configured to:
generate reconstructed samples including reconstructed luma samples and reconstructed chroma samples of a current block in a current picture;
derive adaptive loop filtering (ALF) filter coefficients for an ALF process;
generate ALF-related information based on the ALF filter coefficients;
derive cross-component filter coefficients for a cross-component filtering process;
generate cross-component filtering-related information based on the cross-component filter coefficients; and
encode image information including information for generating the reconstructed samples, the ALF-related information, and the cross-component filtering-related information,
wherein the cross-component filtering-related information includes information on a number of cross-component filters and information on cross-component filter coefficients.
