Abstract
An encoding device, a decoding device, and a storage medium are provided. A reference sample value for a colour component of a current block is determined. A weighting factor is determined according to the reference sample value for the colour component of the current block. A first prediction block for a second colour component of the current block is determined according to the weighting factor and a reference sample value for the second colour component of the current block, where the number of prediction values of the second colour component of the first prediction block is greater than the number of second-colour-component samples in the current block. First filtering is performed on the first prediction block to determine a second prediction block for the second colour component of the current block. A reconstructed value of the second-colour-component sample in the current block is determined according to the second prediction block.
