  • Publication number: 20120242896
    Abstract: A video image processing apparatus has a determination unit that determines whether an interpolation pixel generation position is an edge portion in an oblique direction, and determines a direction of the edge; and a generation unit that generates an interpolation pixel at an interpolation pixel generation position at which there is video image motion and which has been determined, by the determination unit, to be an edge portion in an oblique direction, in use of a pixel that is present in the edge direction, wherein the determination unit determines whether the interpolation pixel generation position is an edge portion in an oblique direction on the basis of whether or not a pixel value one line above or one line below the interpolation pixel generation position increases or decreases locally at positions that are adjacent, in a vertical direction, to the interpolation pixel generation position.
