Abstract: A video coding apparatus including a dividing part that outputs the coding target picture divided for each coding unit (basic CU); a prediction processor that generates a prediction image by performing one of intra prediction and inter-screen prediction; a difference calculator that generates a difference image by calculating a difference between the generated prediction image and an image corresponding to the prediction image in the coding target picture; a residual coder that generates a residual coefficient by performing transform processing and quantization processing on the generated difference image; an integration unit that integrates a plurality of basic CUs included in an N×N-pixel region into one new CU, and a code string generator that generates a code string corresponding to the post-integration new CU by performing variable-length coding and arithmetic coding on coding information and the residual coefficient.
