Abstract: An image forming apparatus includes a storage device for storing a source image, a character region identifier that identifies a character region in the source image, an image acquirer that acquires an image of the character region from the source image, an annotation line identifier that detects an annotation lines in the character region, and identifies a position of the annotation line, and a generator that generates, from the source image, a modified image not containing an image located outside the character region in the source image, and in which the annotation lines have been deleted from the image of the character region.

Abstract: An image processing device includes a storage device that previously stores a document image, a plurality of registered words, and a plurality of font characters, and a control device that functions as: a character region identifier that identifies a character region in the document image; an image acquirer that acquires an image of the character region; a text extractor that extracts a text from the image of the character region; a word identifier that identifies each of words in the text; a word determiner that determines whether each of the words is matched with one of the registered words; and a generator that generates a corrected text by replacing a target character of a non-matching word in the text with, among the font characters, a font character having a first degree of matching not lower than a first rate with the target character and a highest first degree of matching.
