Abstract:
According to the present invention, an image decoding method performed by a decoding device comprises the steps of: deriving a prediction mode of a current block; generating a prediction block of the current block on the basis of the prediction mode of the current block; deriving a neighboring block of the current block; deriving correlation information on the basis of a reconstruction block of the neighboring block and a prediction block of the neighboring block; deriving a modified prediction block of the current block on the basis of the prediction block of the current block and the correlation information; and deriving a reconstruction block of the current block on the basis of the modified prediction block. According to the present invention, a current block can be predicted in consideration of the correlation between a prediction sample and a reconstruction sample of a neighboring block, and a complicated image can be more efficiently reconstructed through the prediction.

Claim (Index 11):
The video decoding method of  claim 10 , wherein:\n the difference value corresponding to each prediction sample included in the prediction block of the current block is derived based on an equation as below: \u2003 \u0394 1 = Rec A \ue8a0 ( 0 , 0 ) - Pred A \ue8a0 ( 0 , 0 ) \u0394 2 = Rec A \ue8a0 ( 0 , 1 ) - Pred A \ue8a0 ( 0 , 1 ) \u22ee \u0394 N = Rec A \ue8a0 ( N , N ) - Pred A \ue8a0 ( N , N ) where RecA(x,y) denotes a reconstructed sample value at coordinates (x,y) of a reconstructed block of the neighboring block, PredA(x,y) denotes a prediction sample value at coordinates (x,y) of a prediction block of the neighboring block, \u0394N denotes a Nth difference value, and a final prediction block comprises N number of samples.
