Interpolation method of digital image data and a circuit therefor
 A method of interpolating digital image data includes steps for calculating an absolute value of the difference between two neighboring pixels of image data, among four neighboring pixels of image data, determining maximum and second-most maximum values among the thus-calculated absolute values and interpolating the image data using the results. An interpolation circuit for performing above-described method includes an edge detector, a pre-filter, a zero-order interpolation area controller, a zero-order interpolator, a movement averaging device, a magnification factor controller and a post-filter.
