    Abstract: Disclosed is an encoding device. The present encoding device comprises a processor which: divides a target block of the current frame into a first area and a second area according to a predetermined division method and an interface communicating with a decoding device; searches for a first motion vector for the first area in a first reference frame, so as to generate a first prediction block including an area corresponding to the first area; divides the first prediction block into a third area and a fourth area according to the predetermined division method, and generates boundary information; searches for a second motion vector for the fourth area corresponding to the second area in a second reference frame, and generates a second prediction block including an area corresponding to the fourth area; merges the first prediction block and the second prediction block according to the boundary information so as to generate a third prediction block corresponding to the target block; and controls the interface to transmit the first motion vector and the second motion vector to the decoding device.
