Abstract:
A decoding method includes: predicting a current block in an image using a reference block, to generate a prediction block; and generating a reconstructed block using the prediction block, wherein the generating includes: filtering for a boundary between the reconstructed block and a decoded neighboring block, using a first filter strength set using first prediction information for prediction of the current block and second prediction information for prediction of the decoded neighboring block; filtering for the boundary using a second filter strength set without using the second prediction information of the current block and the decoded neighboring block; and switching whether to execute the second filtering, based on the boundary, wherein the first filtering is in-loop filtering in which a filtered reconstructed block is used as a reference block for another block, and the second filtering is post filtering outside the loop.

Claim (Index 15):
An image decoding method for decoding an image from a bitstream on a per block basis, the image decoding method comprising:\n predicting a current block in the image using a reference block different from the current block, to generate a prediction block; and generating a reconstructed block using the prediction block, wherein the generating includes:\n first filtering for filtering a boundary between the reconstructed block and a decoded neighboring block neighboring the current block, using a first filter strength which is set using information of the current block and information of the decoded neighboring block; \n second filtering for filtering the boundary using a second filter strength which is determined according to a predetermined method; and \n switching whether or not to execute the second filtering, based on the boundary, \n wherein the reconstructed block whose boundary has been filtered in the first filtering is used as a reference block for another block, and wherein the reconstructed block whose boundary has been filtered in the second filtering is not used as a reference block for another block.
