Abstract
A method for eliminating discontinuity of block boundaries of an image encoded in units of blocks and an apparatus thereof. A filter for eliminating discontinuity of block boundaries of an image encoded in units of blocks with a predetermined size includes: a vertical edge filtering unit which eliminates the discontinuity in the vertical direction of the blocks, by filtering sequentially in units of blocks; a determination unit which determines a start point of discontinuity filtering in the horizontal direction according to a filtering mode of a macroblock formed with the blocks; and a horizontal edge filtering unit. If the vertical direction discontinuity filtering of the blocks is finished to the filtering start point determined by the determination unit, discontinuity filtering in the horizontal direction of the blocks is sequentially performed for which the vertical direction discontinuity filtering is finished. Accordingly, time taken for filtering is reduced and unnecessary memory is not required.
