In one embodiment of the present application, a frame interpolation circuit performs frame interpolation on an input video signal, and outputs a drive video signal containing original and interpolation frames. A motion determination circuit outputs a control signal in accordance with the amount of motion, based on a motion vector obtained by a motion detection circuit. In accordance with the control signal, the frame interpolation circuit increases the proportion of interpolation frames contained in the drive video signal as motion in an image increases, while increasing the proportion of original frames contained in the drive video signal as the motion in the image decreases. As a result, any moving image blur due to following line of sight and noise generated in the interpolation frames are reduced.
