Abstract: Disclosed herein is a method of decoding an image. The method includes acquiring intra chroma prediction information of a current block from a bitstream, deriving an intra chroma prediction mode of the current block based on the intra chroma prediction information, and performing intra prediction with respect to the current block based on the intra chroma prediction mode. The intra chroma prediction mode may be any one of a linear model (LM)) mode, a derived luma (DM) mode, a Planar mode, a Vertical mode, a Horizontal mode and a DC mode, and a first bit of the intra chroma prediction information may be used to determine whether the intra chroma prediction mode is an LM mode.

Abstract: An image decoding method according to the present invention includes reconstructing a residual block by inverse-quantizing and inverse-transforming an entropy-decoded residual block, generating a prediction block by performing intra prediction on a current block, and reconstructing an picture by adding the reconstructed residual block to the prediction block, wherein generating the prediction block includes generating a final prediction value of a prediction target pixel included in the current block based on a first prediction value of the prediction target pixel and a final correction value calculated by performing an arithmetic right shift on a two's complementary integer representation for an initial correction value of the prediction target pixel by a binary digit of 1. Accordingly, upon image encoding/decoding, computation complexity may be reduced.
