Abstract
A device for encoding/decoding the image according to the present invention includes an intra prediction module configured to: determine an intra prediction mode of a current block; determine a scanning order of multiple sub blocks in the current block on the basis of the determined intra prediction mode; and perform intra prediction of the current block on the basis of the determined scanning order.
Claims6
An intra prediction method comprising:
- determining an intra prediction mode of a current block;
- determining a scanning order of multiple sub blocks in the current block on the basis of the determined intra prediction mode;
- and
- performing intra prediction of the current block on the basis of the determined scanning order.
An inter prediction method comprising:
- deriving a motion vector of a current block;
- determining a reference block of the current block on the basis of the motion vector of the current block, the reference block belonging to the same picture as the current block;
- and
- performing motion compensation of the current block on the basis of the determined reference block.
An intra prediction method comprising:
- specifying a nearby sample for intra prediction of a current block;
- performing predetermined filtering on the specified nearby sample;
