PROBLEM TO BE SOLVED: To provide a curved line correction apparatus, method, and program which, when a correction target point on a curved line is selected and the curved line is corrected by moving the correction target point, allows a user to select a correction target point and change a correction target range by a series of user operations, thereby improving the easiness and efficiency of the curved line correction procedure.SOLUTION: A curved line correction apparatus comprises: a correction target receiving unit 12 for receiving selection of a correction target point when an indication mark is placed on an arbitrary point on a curved line which is formed by a plurality of points arranged thereon; a correction target range setting unit 13 for setting a specific range of the curved line, which includes the correction target point, as a correction target range; and a correction unit 14 for correcting the curved line within the correction target range by moving the correction target point and a point within the correction target range by receiving a move of the indication mark. The size of the correction target range is changed by the correction target range setting unit 13 receiving an input of an instruction for changing the range while the indication mark is still being placed on the correction target point.SELECTED DRAWING: Figure 1 |
