Title:
IMAGE ENCODING/DECODING METHOD AND DEVICE FOR SIGNALING CHROMA COMPONENT PREDICTION INFORMATION ACCORDING TO WHETHER PALETTE MODE IS APPLICABLE, AND METHOD FOR TRANSMITTING BITSTREAM
Document Type and Number:
WIPO Patent Application WO/2021/015537
Kind Code:
A1
Abstract:
Provided are an image encoding/decoding method and device. An image decoding method performed by an image decoding device according to the present disclosure may include the steps of: dividing an image and determining the current block; identifying whether a palette mode is applicable to the current block on the basis of a palette mode flag acquired from a bitstream; acquiring palette mode encoding information about the current block from the bitstream on the basis of the tree type of the current block and whether the palette mode is applicable to the current block; and acquiring chroma component prediction information about the current block from the bitstream, when the palette mode is not applicable to the current block.
