Abstract
In the present invention, the appearance frequency of all image information items to be encoded is determined, short code words are allocated from predetermined code words in accordance with leaves of a bifurcating scheme to image information items having an appearance frequency up to a predetermined ranking, in sequential fashion starting from the image information item having the highest appearance frequency, and a predetermined identifier is appended to the beginning of each of the remaining image information items, the resulting codes being taken as the respective code words allocated to said remaining image information items. Thereby, it is possible to provide an image information encoding method whereby decoding by hardware can be performed readily.
