A method of processing image information in which the image information is encoded by the bit plane and compressed by truncating one or more of the bit planes. Since the index parameter indexing the effect of the truncation on the quality of the image information is generated before the truncation, one can determine the bit planes to be truncated based on the index parameter without decoding the image information.
