1. A method for decoding an image, the method comprising:
constructing a coding unit group including at least one of a plurality of coding units divided from the image;
obtaining coding information of the coding unit group; and
decoding at least one of the plurality of coding units included in the coding unit group by using the coding information,
wherein the coding information is determined based on a size of the coding unit group,
wherein the plurality of coding units are decoded based on the coding information of the coding unit group,
wherein prediction modes of the plurality of coding units included in the coding unit group are determined to be an identical prediction mode,
wherein the identical prediction mode of the plurality of coding units in the coding unit group is determined to be an intra prediction mode based on the coding information,
wherein the plurality of coding units constructing the coding unit group have a continuous coding order, and
wherein the coding unit group and the plurality of coding units have a square shape.
