PROBLEM TO BE SOLVED: To provide a method and apparatus for encoding a coding unit of a picture boundary.SOLUTION: A method of encoding an image includes, when a current encoding unit does not include a region that deviates from the boundary of a current picture, a step of encoding the current coding unit when split information parsed from a bit stream indicates a non-split of the current coding unit, and, when the current coding unit includes a region that deviates from the boundary of the current picture, a step of determining at least one split coding unit. The current picture is divided into a plurality of maximum coding units. The maximum coding units are split hierarchically by the split information. When the split information indicates a split of a current depth, the current coding unit of the current depth is split into four rectangular coding units of the lower depth, independently from neighboring coding units. When the split information indicates a non-split of the lower depth, one or more prediction units are obtained from a coding unit of the lower depth. |
