`select a first filter for a first block based at least on a prediction mode used for the
`
`first block;
`
`select a secondfilter for a second block; and
`
`change valuesofpixels in the first block and the second block by using thefirst
`
`filter and the secondfilter such that change amounts of the respective values are within
`
`respective clip widths, the pixels in the first block and the second block being arranged along a
`
`line across a boundary betweenthefirst block and the second block, and the clip widths_applied
`
`to the pixels arranged along the line are asymmetric with respect to the boundary.
