1. An image decoding method to decode a plurality of sub-blocks in a block, comprising:
determining an intra prediction mode;
determining a decoding order among the plurality of the sub-blocks in the block based on the intra prediction mode; and
decoding the plurality of the sub-blocks in the block based on the decoding order, wherein
a width of a sub-block of the plurality of the sub-blocks is equal to a height of the sub-block.
