There is provided an image decoding method for decoding a picture to be decoded by referencing an appropriate picture even when random access reproduction is performed. The method includes: a first storage step (S 100 -S 104 ) for successively decoding respective pictures contained in a stream and storing the pictures used for reference in a picture memory ( 103 ), thereby performing management; a judgment step (S 106 ) for judging whether a random access reproduction has been specified; a state modification step (S 108 ) used when it is judged that the random access reproduction has been specified, for modifying the management state for managing the pictures in the picture memory ( 103 ); and a storage step (S 100 -S 104 ) for successively decoding the respective pictures from the random access reproduction destination assuming that the modified management state is the initial state and storing the pictures used for reference in the picture memory ( 103 ), thereby performing management.
