INTRA PREDICTION METHOD AND APPARATUS AND IMAGE ENCODING/DECODING METHOD AND APPARATUS USING SAME

摘要

The present invention relates to an intra prediction method, an intra prediction apparatus, and a method and an apparatus for encoding/decoding an image using the same. The present invention provides an intra prediction apparatus which takes a weighted average of a pixel value of at least one adjacent pixel included in an adjacent block according to distances between each pixel of a current block and at least one adjacent pixel in order to predict pixel values of each pixel of the current block. According to the present invention, since the current block to be coded is more exactly predicted, the difference between a current block and a predicted block may be reduced to improve the coding efficiency, so that the compression efficiency may be improved.
