Zusammenfassung:Disclosed is a residual signal inter-channel intra prediction encoding method between a residual signal of a luminance component of an image and a residual signal of a chrominance component thereof. It is possible to improve an intra prediction encoding performance when the inter-channel prediction is performed between residual signal of the luminance component and the chrominance component of HEVC, and derive a prediction coefficient for linear prediction at a high speed while the quadtree block structure of the HEVC is not changed. In addition, it is advantageous to avoid degradation in inter-channel prediction performance, which is caused when quadtree block structures of prediction units (PUs) of the luminance component and the chrominance component are different.
