ABSTRACT:
A deblocking filter arithmetic apparatus and a deblocking filter arithmetic method employed for removing block noises generated at decoding image data which have been subjected to the encoding process. Successive pixel data are input to eight arithmetic blocks (101˜108) every two data, a filtering processing arithmetic for removal of the block noises is carried out in parallel so as to conclude the filtering processing arithmetic in a unit of the combination of two arithmetic blocks in an order successively, thereby the pixel data obtained by performing the filtering processing are output by a pipeline system in a unit of the combination of the arithmetic blocks from an output selection circuit (8).
