Abstract
There are provided an image processing apparatus, an image processing method and an image processing program for transforming a target image having no contour of straight line portions. An ellipse Eby which the target image is approximated is calculated (S), a center candidate O.sub.A of the target image is decided (S), a first polygon Passociated with the ellipse and the center candidate is calculated (S), a projective transformation matrix for projectively transforming the first polygon into a second polygon P' associated with an ellipse whose center is a point where the center candidate is projectively transformed is calculated (S), and the target image is projectively transformed based on the projective transformation matrix to obtain a transformation image (S).
