<p><P>PROBLEM TO BE SOLVED: To provide technology for interpolating pixels in a correct edge direction including a gently inclined edge direction. <P>SOLUTION: In a pixel interpolation apparatus 3 for interpolating pixels, an edge pixel detection unit 11 detects edge pixels constituting an edge among pixels on lines positioned above/below the interpolation pixel. A continuous edge detection unit 12 detects edge pixels in which two pixels or more consecutively line up among edge pixels detected by the edge pixel detection unit 11 as a continuous edge. A continuous edge pair detection unit 13 determines the combination of the continuous edges detected on each of the lines above and below the interpolation pixel among the continuous edges detected by the continuous edge detection unit 12. An edge direction determination unit 14 determines the edge direction of the interpolation pixel on the basis of the positional relation of one set of continuous edges determined by the continuous edge pair detection unit 13. An interpolation pixel calculation unit 15 calculates an interpolation pixel using the edge direction determined by the edge direction determination unit 14. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
