Abstract
In curve fitting with respect to a series of data points representing a figure, control points are set for a parameter in accordance with a start point, an end point, and a passing point, and gradients of the respective points. A gradient of a Bezier curve specified on the basis of the start and end points and the control points is obtained for the parameter. If a difference value between the gradient of the Bezier curve and the gradient of the passing point is within a desired value, the curve specified by the start and end points and the control points for the parameter is determined to be a Bezier curve passing the passing point.
