Abstract
The present disclosure relates to an intra prediction method and apparatus and an image encoding/decoding method and apparatus using the same. The disclosure provides the intra prediction apparatus that predicts the pixel values of respective pixels in a current block by weight-averaging the pixel values of one or more adjacent pixels in neighboring blocks to the current block according to the distances between each pixel in the current block and the adjacent pixel(s). According to the disclosure, the current block to be encoded can be predicted more accurately so that the encoding efficiency is improved by reducing the difference between the original block and the predicted block, and thereby video compression efficiency can be improved.
