An image is freely enlarged/reduced in accordance with a user's control instruction to be displayed by reducing noises such as jaggy. An image processing device includes an affine transforming unit for affine transforming coordinates of a control point based on at least an enlarging ratio or a reducing ratio, a number of divisions setting unit for obtaining a ratio of a drawing range of a B'ezier curve after the affine transformation to an actual drawing range and setting the number of divisions of the parameter of the B'ezier curve in accordance with the obtained ratio, a B'ezier curve calculating unit for obtaining the number of curve defining points corresponding to the number of divisions on the basis of the set number of divisions and a coefficient based on a degree and the Bernstein base function, and a B'ezier curve drawing unit for drawing the B'ezier curve to an image memory based on the obtained curve defining point. Particularly, subsequent calculation of the B'ezier curve is canceled, when the actual drawing range does not include the B'ezier curve.
