FIELD: radio engineering, communication.
SUBSTANCE: disclosed is a deblocking which includes: a step for detecting direction of an edge, which indicates the direction of change in pixel value of each block, a step for determining direction of a deblocking filter to be applied to a block boundary in accordance with the detected direction of an edge, a target process block containing a block boundary to be deblocked, and a block in contact with the target process block, and a step for applying the deblocking filter to the block boundary in accordance with the determined direction.
EFFECT: providing deblocking, wherein texture is preserved in inclined directions which must be retained in the image, and block noise can be efficiently reduced, and improved efficiency of encoding all video information.
