PROBLEM TO BE SOLVED: To provide an improved mechanism for repairing degradation in picture quality at the boundary of blocks.SOLUTION: There is provided an image processing device comprising: a stream acquisition unit which acquires a first code stream containing encoded transfer coefficient data for the frequency component of an image including one or more blocks and a second code stream containing encoded error data including errors which occurred when the low order bits of the transfer coefficient data were destructed for the purpose of rate control; a first decode unit which decodes the transfer coefficient data from the first code stream; a second decode unit which decodes the error data from the second code stream; and a synthesis unit which synthesizes the transfer coefficient data and the error data to correct errors in the transfer coefficient data. |
