Abstract

Disclosed are a method and a device for encoding/decoding an image, which perform prediction according to at least two prediction methods in an encoding block. According to an embodiment of the present invention, the method for decoding an image comprises the following steps of: decoding coding mode information of a current encoding block; dividing the current encoding block into at least one prediction block; and generating a prediction sample of the at least one prediction block based on the decoded coding mode information. The coding mode information can be information indicating one among an intra mode, an inter mode and a hybrid mode.
