Intra prediction method and apparatus, and image encoding/decoding method and apparatus using same
A video encoding apparatus using an intra prediction, includes: an intra predictor to predict a current block from a plurality of neighboring blocks of the current block; a subtractor to generate residual signals by subtracting predicted pixels in the predicted block from pixels in the current block; a transformer to transform the residual signals into a frequency domain; a quantizer to quantize the transformed residual signals; and an encoder to encode the quantized residual signals into a bitstream, wherein the intra predictor includes: a weighted pixel calculator configured to calculate a plurality of weighted pixel values of pixels selected in the neighboring blocks by applying weights to the pixels selected in the neighboring blocks.
