1. A decoding method comprising:
generating a reconstructed image; and
performing deblocking filtering on a boundary between a first reconstructed block and a second reconstructed block, each of the first reconstructed block and the second reconstructed block including a plurality of segments which are separated along a line that is perpendicular to the boundary,
wherein the deblocking filtering includes:
judging whether or not to apply a deblocking filter to target pixels in adjacent segments on both sides of the boundary, using sample pixels in only the adjacent segments; and
for each respective line of pixels which is perpendicular to the boundary and to which the deblocking filter is to be applied, one type of deblocking filter is selected from among a plurality of types of deblocking filters, using sample pixels in the respective line of pixels included in a segment of the plurality of segments and without using any sample pixels included in other segments of the plurality of segments, and
wherein each respective line of pixels is separated by the boundary by being intersected with the boundary.
