Abstract
An intra prediction method according to the present invention comprises the following steps: deriving neighboring prediction mode information from a left neighboring prediction mode and a top neighboring prediction mode; deriving an intra prediction mode for a target unit to be decoded, using the derived neighboring prediction mode information; and performing intra prediction for the target unit to be decoded, based on the intra prediction mode. According to the present invention, video encoding/decoding efficiency may be improved.
