A Bezier curve drawing device is configured as follows. A control point coordinate acquiring unit (10) acquires the coordinates of a plurality of control points of a Bezier curve. An inter-control point distance calculation unit (11) selects, using the minimum distance of a resolution for displaying the Bezier curve as a unit, either the horizontal distance or the vertical distance of adjacent control points of the Bezier curve, whichever is greater, adds up thus selected distances between adjacent control points, the added-up value being calculated as an indicator of the length of the Bezier curve. A division number setting unit (12) sets, based on the indicator of the length, the number of divisions to be used when the Bezier curve is divided and drawn. A Bezier division apex calculation unit (16) calculates, according to the number of divisions set by the division number setting unit (12), the coordinates of the end-points of each interval obtained by dividing the Bezier curve. |
