<p><P>PROBLEM TO BE SOLVED: To stably continue decoding even when a picture with an error generated is designated as an anchor picture. <P>SOLUTION: A moving image decoding device includes a picture memory 103 which stores macro block information including motion vector information and described at a macro block unit and image data in which a picture including the macro block is already decoded in association with each other, an error determining unit 104 which determines whether a decoding object picture has an error, an image data replacing unit 109 which, if determined to have an error, replaces the image data of the decoding object picture with the image data of the picture already decoded, a macro block information replacing unit 113 which, if determined to have an error, replaces the macro block information in association with the decoding object picture including the error with macro block information stored in association with a picture already decoded, or a macro block information storing unit 111 which stores information indicating that the decoding object picture includes the error in association with the image data of the decoding object picture. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
