Abstract
A method for dynamically adjusting alignment of a scanned image includes generating a raw scanned calibration image, processing the raw scanned calibration image so as to determine a correction for each horizontal pixel of the image, and applying the determined correction to the entire scanned image so as to produce an aligned image.
Claims20
A method for dynamically adjusting alignment of a scanned image, the method comprising:
- generating a raw scanned calibration image;
- processing said raw scanned calibration image so as to determine a correction for each horizontal pixel of the image;
- and
- applying said determined correction to the entire scanned image so as to produce an aligned image.
1 more element
A storage medium, comprising:
- a machine readable computer program code for dynamically adjusting alignment of a scanned image;
- and
- instructions for causing a computer to implement a method, the method further comprising:
- generating a raw scanned calibration image;
- processing said raw scanned calibration image so as to determine a correction for each horizontal pixel of the image;
- and
- applying said determined correction to the entire scanned image so as to produce an aligned image.
4 more elements
An image scanning apparatus, comprising:
- an image sensor configured to generate a raw scanned calibration image of a scanned document;
- and
- a correction algorithm configured to process said raw scanned calibration image so as to determine a correction for each horizontal pixel of the image;
- and
- said correction algorithm further configured to apply said determined correction to the entire scanned image so as to produce an aligned image.
