ABSTRACT:
An apparatus which processes a digital image and a method therefor which can reduce an error when calculating an output value obtained by interpolating pixel values of the input digital image. The apparatus includes an interpolation processing unit which interpolates an input digital image, and a controller which measures an interpolation interval of pixel values of the digital image, calculates a coefficient by substituting the interpolation interval for a coefficient equation stored in a register, and calculates an interpolation node for the digital image by substituting the coefficient and an output pixel position value of the digital image for an interpolation node calculation equation. The controller controls the interpolation processing unit so as to interpolate the digital image to the interpolation node. As a result, it is possible to reduce an error between an interpolated output pixel position value and an output pixel position value for the pixel values of the input digital image.
