In image data coding and decoding processing, in order to improve efficiency by processing a plurality of factors in one cycle as long as possible, the factors are rearranged, in coding or decoding processing, in a predetermined scan sequence such that significant factors and 0s are paired. In addition, an appropriate scan sequence is selected in accordance with the distribution state of frequencies to further improve the efficiency.
