Abstract:
1. An interpolation pixel value determining method for dividing a unit region including the contour of an object into reference unit sections for each line along a predetermined direction, and finding, using a region interposed between the two reference unit sections as an interpolation unit section, interpolation pixel values in the interpolation unit section, comprising the steps of calculating a luminance total, a moment and a center of gravity in each of the two reference unit sections with the interpolation unit section interposed therebetween; finding from the luminance totals, the moment and the centers of gravity in the two reference unit sections the estimated values of a luminance total, a moment and a center of gravity in the interpolation unit section; and determining each of the interpolation pixel values in the interpolation unit section such that the luminance total, the moment and the center of gravity in the interpolation unit section are respectively values close to the estimated values.
