摘要： Disclosed herein is a method of decoding an image. The method includes generating an inter prediction block by performing inter prediction with respect to a current block, generating an intra prediction block by performing intra prediction with respect to the current block, determining a first weight and a second weight, and generating a final prediction block by respectively applying the first weight and the second weight to the inter prediction block and the intra prediction block. The generating of the intra prediction block includes generating the intra prediction block using a predefined intra prediction mode.

摘要： The present specification discloses a method of decoding an image. The method includes performing dequantization on a current block to obtain a transform coefficient of the current block; performing at least one inverse transform of primary inverse transform and secondary inverse transform on the transform coefficient of the current block to obtain a residual block of the current block; and adding the residual block of the current block and a prediction block of the current block to obtain a reconstructed block of the current block, wherein the secondary inverse transform is performed only when the current block is in an intra prediction mode.
