Abstract
Provided are methods and apparatuses for encoding and decoding an image. The method of encoding the image includes calculating the number of times that encoding information of each of a plurality of sub-blocks included in a current block is exactly predicted, determining whether or not to predictably encode the encoding information of each sub-block, based on the calculated number of times, and predictably encoding the encoding information of each sub-block according to the determination. Using the method can prevent the case in which many bits are required to encode the encoding information due to inexact prediction about the encoding information, thereby decreasing the compression ratio of the image encoding process, and can compress the image with a higher efficiency.
