Techniques for converting mechanical markings on hardcopy textual content into digital annotations in a digital document file. In accordance with some embodiments, the techniques include identifying at least one block of text in a digital (scanned) image of a hardcopy document, and identifying at least one mechanical marking in the digital image of the hardcopy document. The mechanical marking, such as an underline, strike-through, highlight or circle, covers or lies adjacent to the corresponding block of text. An annotated digital document file is generated from the digital image of the hardcopy document. The annotated digital document file includes computer-executable instructions representing the original text of the hardcopy document and at least one annotation corresponding to the mechanical marking in the hardcopy document.

In accordance with an embodiment, an image processing apparatus comprises a scanner; a designation section configured to designate a color presented in an original document as the object to be removed; extraction section configured to extract color information of the color to be removed based on image data which is obtained by reading, using the scanner, a color information extraction sheet on which an image is formed with a material of the color to be removed; and a conversion section configured to form, based on the designation of the designation section and the color information extracted by the extraction section, an image by removing the image data in the color designated to be removed from the image data of the original document.
