Abstract: The present invention provides a method for deriving motion information and a device for encoding an image using depth information. A method for deriving motion information using depth information, according to an embodiment of the present invention, comprises the steps of: comparing each motion information item of a plurality of adjacent blocks that are spatially adjacent to an encoded current block and thereby searching for an adjacent block having the same motion information; comparing, using depth information, whether or not a first object area comprising a block in a reference image temporally corresponding to the current block and a second object area comprising the adjacent block that has been found are the same; and, if the first object area and the second object area are the same, deriving motion information of the adjacent block that has been found as motion information of the current block.
