A video signal processing device according to an embodiment of the present invention includes a motion vector detection unit and a plurality of interpolated image generation units. The motion vector detection unit detects an interpolated motion vector which represents a motion between a first broad image and a second broad image. Each of the interpolated image generation units generates an interpolated partial image corresponding to a divided area by using a first partial image of a first frame, a second partial image of a second frame, and the interpolated motion vector.
