IMAGE ENCODING/DECODING METHOD AND APPARATUS FOR SAME

摘要

According to the present invention, an image encoding/decoding method comprises the steps of: performing an intra prediction on a current block so as to generate a prediction block; performing filtering on a filtering target pixel in the prediction block on the basis of the intra prediction mode of the current block so as to generate a final prediction block; and generating a reconstructed block on the basis of a reconstructed differential block corresponding to the current block and on the final prediction block. According to the present invention, image encoding/decoding efficiency can be improved.

1. An video decoding apparatus comprising:
a prediction block generating unit to generate a prediction block by performing prediction on a prediction target pixel in a current block based on an intra prediction mode of the current block; and a reconstructed block generating unit to generate a reconstructed block based on a final prediction block and a reconstructed residual block corresponding to the current block, wherein the prediction block generating unit performs the prediction on the prediction target pixel based on a first offset when the intra prediction mode of the current block is a vertical mode and the prediction target pixel is a pixel on a left vertical pixel line, and performs the prediction on the prediction target pixel based on a second offset when the intra prediction mode of the current block is a horizontal mode and the prediction target pixel is a pixel on an upper horizontal pixel line, the left vertical pixel line being one vertical pixel line positioned at a leftmost side of the current block and the upper horizontal pixel line being one horizontal pixel line positioned at an uppermost side of the current block.
