PROBLEM TO BE SOLVED: To provide the data input method and its device which generate feature data coordinates of high efficiency on the basis of input data based upon oversampling and have a minimum process load regarding the correction of feature data. SOLUTION: Point coordinates are inputted (21, 22, and 24) through oversampllng. Then a tertiary spline curve is calculated (25) from the inputted point coordinates. Then feature points of a curved are acquired (27 and 26) on the basis of respective points on the calculated tertiary spline curved. Then those obtained feature points are outputted (23). |
