PURPOSE:To shorten a processing time by thinning a point string which is redundant as against object of a curve approximating out of the point strings inputted from a locus data input means and executing curve approximation after adding the point being effective for curve approximation. CONSTITUTION:A locus data input means 10 inputs a pen locus in a characteristic point pick-up means 11 as the coordinate position string of the point string. The characteristic point pick-up means 11 thins the point being redundant in generating the curve approximating the point strings out of the point strings inputted from the locus data input means 10 and gives the remaining point strings to a characteristic point compensating means 12. The characteristic point compensating means 12 generates the point being suitable for generating the approximating curve in addition to the point strings from the point strings given from the characteristic point pick-up means 11, adds the generated point as the new characteristic point and inputs it to a curve generating means 13. The curve generating means 13 generates curve data being the set of parameters stipularing plural Bezier curves from the inputted characteristic points and generated curve data is stored in a curve storage means 14. |
