For finding an inclination of an image rapidly and correctly, an image processing device includes a CCD picking up an image, an edge detection unit detecting an edge of an image relating to the picked-up image, a rotation unit rotating the detected edge in an image plane, an operation unit deriving a characteristic amount of rotated edge and an inclination detection unit detecting an inclination of the picked-up image based on the derived characteristic amount.
