- Abstract
- The invention discloses a video decoding apparatus, a video encoding apparatus, and a computer-readable recording medium. The video decoding apparatus includes: an entropy decoding unit for entropy decoding of the residual block information; and a residual block reconstruction unit for performing inverse quantization and inverse transformation on the entropy-decoded residual block information to reconstruct a residual block; a prediction block generating unit that performs intra prediction on a current block using a reference pixel to generate a predicted block; and an image reconstruction unit that adds the reconstructed residual block to the predicted block to reconstruct the image, wherein in the vertical prediction mode or the horizontal prediction mode, correction using the final correction value is performed only for a luminance signal.
