Abstract
A method for colour component prediction comprising: determining a neighbouring reference sample set of a current block, and determining a preset parameter value corresponding to the current block, wherein the neighbouring reference sample set comprises at least one reference sample; caching the neighbouring reference sample set and the preset parameter value to create an input reference sample set; determining an input sample matrix using a first preset calculation model according to the reference sample set; and performing colour component prediction on the current block according to the input sample matrix to obtain a prediction block of the current block.
