    • A feature point calculating device 21 calculates feature points with a sequence of input coordinate points. A symmetrical axis alternative calculating device 22 references the feature points and calculates symmetrical axis alternatives. A first determination symmetrical axis determining device 23 extracts the most horizontal symmetrical axis alternative and the most vertical symmetrical axis alternative from the symmetrical axis alternatives calculated by the symmetrical axis alternative calculating device 22. A first symmetry input point set calculating device 24 calculates symmetry determination segments of one of the horizontal and vertical symmetrical axis alternatives. A first symmetrical axis distance calculating device 25 calculates the distance between the center point of each symmetry determination segment and the symmetrical axis alternative. A first symmetry determining device 26 calculates a deviation of the calculated distances. When the deviation does not exceed a predetermined threshold value, the first symmetry determining device 26 determines that the input figure is line symmetrical to the symmetrical axis alternative. A symmetrizing process device 27 compensates the input figure so that sets of input coordinate points calculated by the first symmetry input point set calculating device 24 become line symmetrical to the symmetrical axis alternative.
