摘要

In a video coding device, an intra-predict unit (11) predicts a block to be processed on the basis of an adjacent reconstructed image. A first color difference intra-predict mode coding unit (12) codes an intra-predict mode of a first color difference component on the basis of an intra-predict mode of a luminance component. A second color difference intra-predict mode coding unit (13) codes an intra-predict mode of a second color difference component according to the intra-predict mode of the first color difference component.
