Abstract
A multiple non-directional scanning method. A document preview scanning is carried out from one end of the document to the other. The preview image is next analyzed to provide a set of scan parameters. After setting the scan parameters, the scanner performs a backward scanning operation from the other end of the document back to the original start-up position to obtain a final scan image.

- capturing a second portion image from the document as the chassis moves backward, wherein the first portion image and the second portion image has no overlapping sections;
- and
- combining the first and the second image to form a final scan image.
