Abstract:
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.

Claim (Index 1):
An apparatus for decoding video by applying a filter on prediction target pixels of a prediction block selectively based on a size of a current block, the apparatus comprising:\n a prediction block generating unit to generate the prediction block by performing intra prediction on the current block for a DC mode, and a reconstructed block generating unit to generate a reconstructed block based on the prediction block and a reconstructed residual block corresponding to the current block, wherein the prediction block generating unit generates prediction values of the prediction target pixels of the prediction block using the filter for the DC mode during the intra prediction when the size of the current block is smaller than a predetermined block size, the prediction target pixels are located in a vertical pixel line at a leftmost side of the prediction block and located in a horizontal pixel line at an uppermost side of the prediction block, and wherein the filter has at least one of a predetermined fixed filter shape, a predetermined fixed filter tap and a plurality of predetermined fixed filter coefficients regardless of the size of the current block.
