IMAGE DECODING DEVICE AND IMAGE ENCODING DEVICE

摘要

There is provided an image decoding device capable of removing block distortion even when the block decoding sequence is modified. The image decoding device (100) includes: a variable length decoding unit (111) for successively decoding the blocks; a frame memory (102); a deblocking filter processing unit (119) for subjecting each of the blocks which has been decoded to filter processing; first execution state switches (103, 104) for causing the frame memory (102) to store each block decoded and execute filter processing on the block stored; second execution state switches (103, 104) for causing to execute filter processing on the block decoded; and a control unit (101) for switching between the first execution state and the second execution state of the switches (103, 104).
