<p><P>PROBLEM TO BE SOLVED: To provide an image coding method and an image decoding method or the like by which an image can be restored correctly even if part of memory management information is lost by a transmission channel error, and an image coding method and an image decoding method or the like by which a candidate of a reference image that can be referred to is selected more appropriately and coding efficiency is improved. <P>SOLUTION: The image coding method includes: a step (Step 100) for executing coding of an image; a step (Step 102) for judging whether an unneeded memory exists; a step (Step 103) for coding the memory management information for releasing the unneeded memory when the unneeded memory exists; a step (Step 104) for releasing the unneeded memory; a step (Step 105) for judging whether the memory management information that releases the unneeded memory by coding of an image immediately before; and a step (Step 106) for coding again the memory management information that releases the unneeded memory when the memory management information is coded. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
