According to one embodiment, a video signal interpolation apparatus has: a correlation calculating unit calculating correlation calculation values by correlating each of a plurality of peripheral pixels with another plurality of peripheral pixels existing in a periphery of an object interpolation pixel; a sub-pixel estimation unit estimating a position of sub-pixel having an equivalent luminance value to that of the respective peripheral pixel based on the plurality of correlation calculation values calculated for each of the plurality of peripheral pixels; and a weighted average calculating unit calculating a weighted average of a pixel value in accordance with distances between each of the sub-pixel and the object interpolation pixel to determine a pixel value of the object interpolation pixel.
