Abstract
A mark detection apparatus includes a reading unit, a converter, and a determination part. The reading unit reads an image on a document. The converter compares respective portions of the image read by the reading unit with a plurality of preset reference patterns, and converts a portion of the image to a character associated with a corresponding reference pattern. The determination part determines that the portion of the image to have been compared on the document is a mark in a case in which the character converted by the converter is a preset first reference character, and that the portion of the image to have been compared on the document is not a mark in a case in which the character converted by the converter is not a preset first reference character.
