ABSTRACT:
An apparatus includes a first-acquisition unit acquiring, from target image data, an input image pattern including pixel values within a predetermined range with reference to each of ideal corresponding points, a second-acquisition unit acquiring, as candidate image patterns, from search-image-pattern data, a first candidate image pattern including pixel values within the predetermined range, a finding unit finding, from the search-image-pattern data, an estimated image pattern as a second candidate image pattern of the candidate image patterns which has a smaller difference from the input image pattern than other candidate image patterns, a first setting unit setting pixel values of positions corresponding to the ideal corresponding points in the estimated image pattern as pixel values at the ideal corresponding points, and a conversion unit converting a resolution of the target-image data using the N-dimensional coordinate values and the pixel values corresponding to the N-dimensional coordinate values.
