METHOD AND EQUIPMENT FOR ENCODING/DECODING IMAGES FOR PERFORMING INTERNAL PREDICTION AND METHOD FOR TRANSMITTING BIT STREAM Russian patent published in 2024 - IPC H04N19/186 H04N19/96 H04N19/11 

FIELD: physics.

SUBSTANCE: invention relates to a method and equipment for encoding/decoding an image using internal prediction. Disclosed is a method and equipment for encoding/decoding images. Image decoding method comprises determining whether or not to apply internal prediction to a current block of chroma signals, based on the information relative to the prediction of the current of chroma signals, extracting the intra prediction mode of the current block of chroma signals based on the intra prediction mode of the corresponding luminance block, corresponding to current block of chroma signals, and the chroma signal internal prediction mode information of the current block of chroma signals when the internal prediction is applied to the current block of chroma signals, and generating a prediction block of the current block of chroma signals by performing intra prediction based on the intra prediction mode of the current block of chroma signals. When the intra prediction mode of the corresponding luminance block is not present, the intra prediction mode of the current block of chroma signals is derived based on the default intra prediction mode.

EFFECT: high efficiency of encoding/decoding.
