DYNAMIC IMAGE DECODING METHOD, DYNAMIC IMAGE DECODING APPARATUS, AND PROGRAM RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To enhance a picture quality by eliminating deterioration of the quality thereof due to an error in correction procedures without a noticeable deterioration in the picture quality caused by decoded image data correction procedures.

SOLUTION: A dynamic image decoding apparatus comprises: an decoding device 1 for decoding an input stream for each macroblock to generate decoded image data; a transmission error detecting device 3 for detecting a transmission error of the input stream; and a stream error detection device 6 for detecting a stream error of the input stream, wherein when a transmission error is detected, the decoded picture data is corrected in macroblock unit, and when a stream error is detected, the decoded picture data is corrected in video packet unit.
