Abstract:
A filtering method according to the present invention is for filtering a plurality of blocks included in an image, and comprises: determining whether each of the blocks is an IPCM block or not; filtering a non-IPCM block that is not an IPCM block among the blocks to generate filtered data; outputting the filtered data as pixel values of the non-IPCM block, and outputting pixel values of the unfiltered IPCM block as pixel values of the IPCM block.

Claim (Index 1):
A decoding method of decoding an image from an encoded bitstream on a block-by-block basis, the decoding method comprising:\n filtering two adjacent blocks to generate filtered data, using values of pixels respectively included in the two adjacent blocks; determining whether each of the two adjacent blocks is an Intra Pulse Code Modulation (IPCM) block or a non-IPCM block; and when the two adjacent blocks are an IPCM block and a non-IPCM block, generating a reconstructed image by replacing a filtered value of the pixel in the IPCM block with an unfiltered value of the pixel in the IPCM block.
