Abstract
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.
Claims19
An image processing device comprising:
- an image receiving unit to receive an original image data;
- an edge detection unit to detect an edge data included in an image data related to said received original image data;
- a rotation unit to rotate said detected edge data;
- an operation unit to derive a characteristic amount of said rotated edge data;
- and
- an inclination detection unit to detect an inclination angle of said received original image data based on said derived characteristic amount.
