Disclosed are a video encoding method for generating a restored image which minimizes the disparity from an original image and an apparatus therefor, and a video decoding method and an apparatus therefor. The video decoding method, according to the present invention, comprises: parsing offset merge information of the present block from a received bitstream; restoring offset types and offset values from among offset parameters of the present block on the basis of the offset merge information; and, on the basis of an edge type or a pixel value band type of the current block, selecting, from among the offset values, an offset value corresponding to the edge class or the pixel value band of the restored pixel that has been determined, and adjusting the pixel value of the restored pixel by the amount of the offset. |
