Abstract
In curve fitting for straight short vectors representing an original figure, an internally dividing point setting section sets, on two adjacent vectors, internally dividing points at which the vectors are divided internally in predetermined ratios. An interpolation point setting section sets the intersection of the straight line passing the internally dividing points of the two adjacent vectors and the perpendicular passing the connecting point of the two adjacent vectors as an interpolation point. In a curve-fitting process section, the curve fitting is performed on the basis of the acquired interpolation point.
