摘要

An image reading apparatus detecting scratch and dirt information of a film document without the need for complex structures and complex control in the image reading apparatus. The apparatus can read a transmissive original document and/or a reflective original document. The apparatus includes a first light source that illuminates the transmissive original document, a second light source that illuminates one of the reflective original document and the transmissive original document, an image sensor that generates electronic image data, a detector unit that detects non-image information from the image data, and a correction unit that corrects the image data, based on the non-image information detected by the detector unit.
