1. A method for processing a plurality of motion vectors for a video frame to be interpolated using a first reference frame and a second reference frame, each reference frame having a content map, the method comprising: partitioning the video frame to be interpreted into a plurality of areas; determining a number of motion vectors passing through one area of the plurality of areas based on the content maps of the first reference frame and the second reference frame; and generating a motion vector for assigning to the one area based on the number of motion vectors passing through the one area.
