摘要

A filtering method according to the present invention is for performing deblocking filtering on the boundary between an IPCM block and a non-IPCM block adjacent to each other in an image and including: determining a first quantization parameter for the non-IPCM block (S401); determining a second quantization parameter for the IPCM block, using the first quantization parameter (S402); determining a filter strength for the boundary, using the first quantization parameter and the second quantization parameter (5403); and performing the deblocking filtering on the boundary using the determined filter strength (S404).
