ABSTRACT:
An encoding process is provided which can easily control the compression rate or guarantee a maximum required processing time when representing the factor data, obtained from a wavelet transformation, as codes corresponding to each of the bit planes. To this end, a plurality of sets of table data each specifying the bit planes to be discarded for each of the sub bands are provided, and by selecting one of these sets according to the various conditions set forth such as the desired compression rate or a maximum required processing time, the amount of data to be encoded can be optionally set and/or a maximum required processing time can be optionally set for an apparatus with a predetermined processing speed.
