- Abstract
- The invention discloses a video decoding apparatus, a video encoding apparatus, and a computer-readable recording medium. The video decoding apparatus includes: a residual block reconstruction unit that reconstructs a residual block by inverse quantization and inverse transformation of entropy-decoded residual block information; a prediction block generation unit that generates a prediction blockby performing intra prediction on the current block using the reference pixels; and a screen reconstruction unit, wherein the picture is reconstructed by adding the reconstructed residual block to theprediction block, in a case of a vertical prediction mode or a horizontal prediction mode, correction using a final correction value is performed only for a luminance signal, and wherein the reference pixel for the intra prediction is a previously decoded pixel adjacent to a current block.
