An image processing method comprising:
- dividing a picture of an image into a plurality of coding units which are basic units in which an inter prediction or an intra prediction is performed;
- and
- selectively configuring a prediction mode list for deriving a prediction direction of the decoding target block from an intra prediction direction of an decoding target object from an intra prediction direction of a neighboring block adjacent to the decoding target object for an intra predicted unit among the divided coding units;
- wherein includes the picture or the divided coding units is/are divided into a binary tree structure in the step of dividing the coding units.
An image processing method comprising:
- receiving an encoded bit stream;
- performing inverse quantization and inverse transform on the input bit stream and obtaining a residual block;
- obtaining a prediction block by performing an inter prediction or an intra prediction;
- reconstructing an image by summing the obtained residual block and a prediction block;
- and
- performing adaptive loop filtering by each coding unit for the reconstructed image;
- wherein a coding unit, which is a basic unit in which an inter prediction or an intra prediction is performed, is a block divided from a coding tree unit using a binary tree structure, and
- a prediction mode list for deriving a prediction direction of the decoding target block from an intra prediction direction of a neighboring block adjacent to the decoding target block is selectively configured for an intra predicted unit of the divided coding units in the step of obtaining the prediction block.
