Abstract
An image reading apparatus reads an image from a document being simultaneously fed by the apparatus. A document feeder unit feeds the document on a original plate. A first image reading unit reads an image from the fed document at a first document-read position on the original plate. A second image reading unit reads an image from the fed document at a second document-read position located at a predetermined distance from the first document-read position in a document feeding direction. An abnormal pixel detection unit detects abnormal pixels resulting from rubbish moved between the first document-read position and second document-read position on the original plate together with the document.
