An image forming apparatus includes a central processing unit (CPU), a storage device storing a document digitization program, and a reading device that reads an image from an original document. The CPU executes the document digitization program to implement an image acquiring section, an added handwriting extracting section, and a document editing section. The image acquiring section acquires an image of a markup document, which is the original document modified by handwriting, using the reading device. The added handwriting extracting section extracts an added handwriting from the image of the markup document. The document editing section edits a raw original document, which is the original document without the modification, according to a modification instruction given through the added handwriting to generate a digitized document. The document editing section alters a position of at least some of characters and graphics included in the raw original document to generate the digitized document.

An image processing apparatus includes a processor, and memory storing computer readable instructions, when executed by the processor, causing the apparatus to function as a storage destination specifying unit configured analyze original image data generated by optically reading a document, the document including a body area having information written therein, and also including a storage destination specifying area representing information for specifying a storage destination to store target image data representing a target including the body area, so as to specify the storage destination to store the target image data, and a target image data providing unit configured to provide the target image data to the specified storage destination.

An image processor includes a detector, a processor, and a generator. The detector is configured to detect whether a specific pattern is present at a first position in first image data. The processor is configured to generate data information, based on a detection result derived from the detector. The generator is configured to generate second image data by disposing the data information at a second position that corresponds to the first position.
