ABSTRACT:
An image expanding apparatus is disclosed, that comprises a coding parameter detecting portion for detecting coding parameters from an image code; an expanding parameter designating portion for designating expanding parameters; an extracting parameter calculating portion for calculating an extracting parameter based on the coding parameters and the expanding parameters; and a code extracting portion for extracting a code necessary for obtaining an expanded image designated by the expanding parameters from the image code with reference to the extracting parameter.
