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 15):
The video encoding method of  claim 14 , wherein the modified prediction block is derived based on an equation as below:\n P \u2032( x,y )=\u03b1 P ( x,y )+\u03b2 where P\u2032(x,y) denotes a modified prediction sample value at coordinates (x,y) included in the modified prediction block, P(x,y) denotes a prediction sample value at coordinates (x,y) included in the prediction block of the current block, \u03b1 denotes the weight per block unit, and \u03b2 denotes the offset per block unit.
