Abstract
An intra prediction image decoding apparatus is provided with a prediction parameter derivation circuitry that derives prediction parameters of multiple luminance blocks. A Cross-component Linear Model (CCLM) is used to specify the model and the prediction parameter is obtained, and thus an intra prediction image with reference to the prediction parameters is generated.
