摘要

A CTB coding unit (102) generates a block code string by coding image data of a block to be coded and acquires local decoded image data of the block to be coded. A loop filter (104) filters the local decoded image data on the basis of a filter parameter for the block to be coded. A filter parameter coding unit (105) codes an acquisition flag indicating whether or not the filter parameter for the block to be coded is acquired from an adjacent coded block, and codes the filter parameter for the block to be coded when the acquisition flag indicates that the filter parameter for the block to be coded is not acquired from the adjacent coded block.
