摘要： An image decoding method, apparatus and program for decoding coded picture data is disclosed. In the method, apparatus and program, the coded picture data is entropy-decoded to derive four transform coefficient strings each comprising entropy-decoded sixteen (16) transform coefficients. The four transform coefficient strings are combined into an 8x8 block of entropy-decoded sixty four (64) transform coefficients by de-interleaving the four strings in such a manner as to select a lower frequency transform coefficient alternately from the four strings and arrange it in the 8x8 block in an order of a low frequency to a high frequency. An inverse orthogonal transform is then performed on the 8x8 block of the entropy-decoded sixty four (64) transform coefficients.

摘要： Image encoding apparatus 10 according to the present invention is an image encoding apparatus 10 for dividing image signals into blocks, performing an orthogonal transform of each block, reading resultant orthogonal transform coefficients to obtain a coefficient string, and performing entropy coding, which has block selector 14 for selecting a size of a block for the orthogonal transform, out of a plurality of blocks of different sizes; coefficient string divider 12 for, when a block of a size larger than a minimum size is selected by block selector 14, dividing a coefficient string in the block into a plurality of coefficient strings of a length equal to that of a coefficient string in a block of the minimum size; and encoder 13 for performing entropy coding adapted to the coefficient string in the block of the minimum size. This substantializes the image encoding apparatus capable of achieving efficient entropy coding in the orthogonal transform of variable sizes.
