Image processing apparatus including image rotator for correcting tilt of the image data

A method for processing image data comprising the steps of:

• receiving image data;
• setting a desired rotation angle based on the image data;
• modifying the image data according to a relationship between the set desired rotation angle and a predetermined value, wherein
• tilt of an image is corrected by rotation of the image data.

An image processing apparatus comprising:

• a rotator which rotates image data by a set desired rotation angle;
• and
• a controller which controls the rotation by said rotator according to a characteristic of the image data, wherein
• tilt of an image is corrected by rotation of the image data.

A method for processing image data comprising the steps of:

• rotating image data by a set desired rotation angle;
• and
• controlling the rotation according to a characteristic of the image data, wherein
• tilt of an image is corrected by the rotation of the image data.

An image processing apparatus comprising:

• an image reading unit which reads a document put on a set position to generate image data, said image reading unit including a detector which detects a tilt angle of the document put on the set position;
• a calculator which calculates a first magnifying power for reading the document by said image reading unit according to the tilt angle detected by said detector;
• and
• a rotator which rotates image data of the document by the tilt angle detected by said detector to correct tilt of the image data, the image data to be rotated by said rotator being image data which has been read at the first magnifying power by said image reading unit.

A method of processing image data comprising the steps of:

• detecting a tilt angle of each document put on a set position;
• calculating a magnifying power for reading the document to the detected tilt angle;
• reading the document at the magnifying power to generate image data;
• and
• rotating the image data of said each document at the magnifying power by a desired rotation angle set in accordance with the detected tilt angle to correct tilt of an image.

An image processing apparatus comprising:

• a rotator which rotates image data by a set desired rotation angle;
• a modifying section which modifies the image data which have been rotated by said rotator;
• and
• a controller which controls the modification by said modifying section according to a characteristic of said image data, wherein
• tilt of an image is corrected by the rotation of the image data the.

A method for processing image data comprising the steps of:

• receiving image data;
• rotating the image data by a set desired rotation angle based on the image data;
• determining a characteristic of the image data;
• and
• modifying the rotated image data according to the characteristic thereof, wherein
• tilt of an image is corrected by rotation of the image data.
