Title:
METHOD AND APPARATUS FOR ENCODING INTRA PREDICTION MODE FOR EACH CHROMA COMPONENT
Document Type and Number:
WIPO Patent Application WO/2023/219290
Kind Code:
A1
Abstract:
A method and an apparatus for encoding an intra prediction mode for each chroma component are disclosed. In the present embodiment, an image decoding apparatus decodes, from a bitstream, first intra prediction mode information for a first chroma channel of a current chroma block. In addition, the image decoding apparatus decodes, from a bitstream, second intra prediction mode information for a second chroma channel of a current chroma block. Here, the first intra prediction mode information includes at least one of a first cross-component linear model (CCLM) mode flag, a first CCLM mode index, and a first chroma intra prediction mode indicator. In addition, the second intra prediction mode information includes at least one of a second CCLM mode flag, a second CCLM mode index, and a second chroma intra prediction mode indicator.
