In one embodiment, the apparatus includes a decoder configured to obtain quantization information of a first block, and determine a filtering coefficient based on values obtained from a table using the quantization. Four successive filtered pixel values in horizontal direction are obtained by the decoder based on the filtering coefficient, and four successive filtered pixel values in the vertical direction are obtained by the decoder based on the filtering coefficient after obtaining the four successive filtered pixel values in the horizontal direction.
