A digital image interpolation method and apparatus for correcting a pixel value of an image to thereby minimize a stair-stepping artifact and emphasize a contrast of the edge pixel. The method and apparatus are provided for calculating an interpolation factor and an edge correction operation value. The method and apparatus then perform a first interpolation and a second interpolation using the calculated interpolation factor, and calculate a correction interpolation pixel value for the interpolation location of the magnified image using adjacent pixel values of the adjacent pixels, a first pixel value obtained by the first interpolation edge correction operation value, an edge correction factor for edge correction, and an edge sharpness factor for distinctly representing an edge to enhance image quality in an edge area of a magnified image.
