Abstract:
1. A document reading apparatus comprising: a reading unit configured to read an image of a document and output multivalued data of the read image of the document; a moving unit configured to relatively move the document and the reading unit; a storage unit configured to store multivalued data or binary data of the image of the document; and a control unit configured, in reading the image of the document in a monochromatic document reading mode, to execute magnification by causing the reading unit to read the document while the moving unit relatively moves the document and the reading unit at a speed determined according to a magnification ratio, binarize the multivalued data output from the reading unit and store the binary data on the storage unit and configured, in reading an image of the document in a color document reading mode, to execute magnification on data output from the reading unit by causing the reading unit to read the document while the moving unit relatively moves the document and the reading unit at a predetermined speed, and store the multivalued data output from the reading unit on the storage unit and executed magnification on the multivalued data stored on the storage unit.
