FIELD: information technology.
SUBSTANCE: image decoding method includes a step of obtaining prediction mode information of the current unit from a bit stream. Further, the method involves determining a unit combined with the current unit from a first unit combined with the current unit in the previous frame, and a second unit combined with the current unit in the next frame to obtain motion vector predictor candidates for the current unit based on the obtained prediction mode information. Motion vector predictor candidates for the current unit are also obtained using the determined unit combined with the current unit.
EFFECT: high accuracy of predicting and encoding a motion vector.
