According to an embodiment, a method of predicting and encoding a motion vector includes: (a) obtaining a motion vector of a target partition in a frame image of an encoding target; (b) determining one first predicted motion vector candidate from motion vectors of one or more partitions belonging to the left adjacent region of the target partition; (c) determining one second predicted motion vector candidate from motion vectors of at least one partition belonging to an upper adjacent region of the target partition; (d) selecting an optimal prediction motion vector based on a comparison of the motion vector of the target partition with one or more prediction motion vector candidates including the first prediction motion vector candidate and the second prediction motion vector candidate, and selecting the selected optimal prediction motion vector. Outputting predictive motion vector indication information for specifying a; And (e) encoding the predicted motion vector indication information.
