Abstract: Aspects of the disclosure provide a method and an apparatus including processing circuitry that decodes prediction information indicating a cross-component linear model (CCLM) mode being applied to a chroma block in a current picture. For a first region in the chroma block, the processing circuitry determines a first adjustment value used to modify an offset parameter in the CCLM mode based on a first subset of reconstructed samples in a luma block collocated with the chroma block. The first subset of the reconstructed samples does not include one or more samples in the luma block. The processing circuitry updates the offset parameter based on the first adjustment value. The processing circuitry determines a second adjustment value used to modify a slope parameter in the CCLM mode based on a second subset of the reconstructed samples in the luma block and updates the slope parameter based on the second adjustment value.
