<p>Disclosed are a method and an apparatus to encode an image and a method and an apparatus to decode the image. The method to encode an image comprises: splitting a current picture into maximum coding units; determining a split structure of the maximum coding units and a prediction mode and reduction of each split coding unit by encoding image data of the maximum coding units based on the depths of the coding units; setting reduction information and skip mode information about each of the coding units and the reduction information containing whether a coding unit of a lower depth, whereby each of the coding units is included, is split or not; and encoding the reduction information and skip mode information set according to each coding unit.</p> |
