Abstract:
The present disclosure relates to deblocking filtering which is applicable to smoothing the block boundaries in an image or video coding and decoding. In particular, the deblocking filtering is either strong or weak, wherein the clipping is performed differently in the strong filtering and the weak filtering.

Claim (Index 1):
An image decoding method for decoding an encoded image on a per block basis, the image decoding method comprising:\n determining, on a per line basis, (i) whether or not a filter is to be applied to a boundary between a block and a neighboring block adjacent to the block, the block and the neighboring block being included in a reconstructed image corresponding to the encoded image, and (ii) a width of the filter when the filter is determined to be applied; and filtering, on a per line basis, the boundary when the filter is determined to be applied, wherein in the filtering, when the width of the filter is a first width, sample pixels in a second width are used, the first width being narrower than the second width, in the filtering, when the width of the filter is a third width, the third width being narrower than the first width, sample pixels in a fourth width are used, the third width being narrower than the fourth width, and in the determining, when determining whether or not the filter is to be applied to a current line using only results of comparing between a value calculated using pixel values and a threshold, the pixel values are in the current line and included in the block or the neighboring block.
