IMAGE CODING METHOD, IMAGE CODING APPARATUS, IMAGE CODING CIRCUIT, INFORMATION RECORDING MEDIUM, AND COMPUTER PROGRAM

摘要

An image coding method is disclosed by which plural code data sets each having a different code amount are generated from one image data set that includes a target code amount setting step for setting a different target code amount for each of the code data sets; an entropy code generation step for applying entropy coding processing to the image data set or data obtained by applying predetermined processing to the image data set so as to generate plural entropy codes; a code amount control step for specifying one of the entropy codes to be truncated so as to control a code amount for each different target code amount; and a code data generation step for truncating the one of the entropy codes specified in the code amount control step and generating the corresponding code data set.
