Abstract
In a data coding method for obtaining coded data by dividing input data into different-length division blocks, the input data is divided into different-length blocks in accordance with a distortion value indicative of an error between the input data and approximate data based on the input data; variable length quantized data is obtained by quantizing the approximate data associated with the input data of each of the blocks; status data indicative of the state in which the input data is divided into the blocks is obtained; and the coded data is obtained by combining the quantized data and the status data. When the input data is divided into a plurality of blocks of unequal lengths, the amount of the coded data is determined so that it is substantially coincident with a predetermined data amount.
