Zusammenfassung:The invention relates to a method for correcting an image acquired by a hand¬ held scanning device. The binarized image of the acquired image is cropped by removing columns on the left end and on the right end of only first components. A work image is created from the cropped image by replacing in each row of components series of first components smaller than a predetermined distance with series of second components. In the work image, a central line is identified. The identified central line in the work image is used to identify the corresponding central line in the cropped image forming a central line image, and in the central line image the central text line is straightened.
