Abstract
A document scanning method comprises causing relative movement between a document and first and second imaging elements, such that each of a succession of scan lines of the document is exposed in turn to the imaging elements; generating first and second image data words representative of overlapping portions of each scan line; and concatenating at least a portion of the words to generate a third word representative of the scan line, the method being characterised by the steps of cross-correlating at least a portion of each of the words to identify a portion of the second word that is included in the first word; discarding a portion of at least one of words; concatenating the first word or remainder thereof with the second word or remainder thereof to form the third word; and, if necessary, compressing or expanding the third word by linear interpolation so as to obtain a word of a predetermined length.
