Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that prediction may be impossible when a motion vector that is applied by an error concealment for an error block on a boundary of a frame is used as it is for motion compensation since, when there is an error in an inputted encoded bit line in a digital image decoding device, error concealment is performed by using only a motion vector of a macro block in a line positioned just above a macro block, by one line, that has caused an error.  <P>SOLUTION: When an error is detected by an error detecting part 101, a motion vector of a block near an error block stored in a motion vector storage part 102 is set in a motion vector setting part 103. In the motion vector storage part 102, a zero vector is stored as the motion vector of the error block. A motion compensating/decoding part 105 compensates/decodes the motion based on the motion vector set in the motion vector setting part 103.  <P>COPYRIGHT: (C)2003,JPO
