INTRA PREDICTION METHOD AND DEVICE FOR PREDICTING PREDICTION UNIT AND DIVIDING PREDICTION UNIT INTO SUB-UNITS

WIPO Patent Application WO/2020/185004

A1

A reference sample construction method and an image decoding device are disclosed. An image decoding method according to an embodiment of the present invention comprises the steps of: determining whether or not a current block is to be divided into a plurality of sub-blocks; when the current block is divided into the plurality of sub-blocks, on the basis of division information decoded from a bitstream, and the width and height of the current block, determining the number of sub-blocks and the division direction in which the current block is divided from among horizontal division and vertical division; reconstructing the current block by sequentially reconstructing, by using intra prediction, the plurality of sub-blocks divided according to the division direction and the number of sub-blocks; and setting up a grid at N sample intervals in the horizontal and vertical directions and deblocking-filtering boundaries matching a boundary of the grid from among boundaries between the plurality of sub-blocks in the current block.
