Abstract
A video-signal processor includes: a first correlation detector obtaining a correlation value of every symmetric pair of pixels positioned in point-symmetry around an interpolation pixel on an interpolation line interpolated between two real lines; a second correlation detector obtaining a correlation value of every pair of pixels for the symmetric pair of pixels and parallel pair(s) of pixels positioned in a direction parallel to a direction of the symmetric pair of pixels; a correlation-direction deciding unit deciding one of a correlation direction based on the correlation value from the first correlation detector and that based on the correlation value from the second correlation detector as a correlation direction which is a direction of the pair of pixels used for generating the interpolation pixel; and an interpolation pixel generator generating a pixel signal of the interpolation pixel using a pair of pixels based on decision result of the correlation-direction deciding unit.
