Abstract: A scanner includes a reference backing member, a scanning module, a transmission mechanism and a processing module. The scanning module scans the reference backing member and an original including first and second documents. The transmission mechanism moves one of the original and the scanning module relatively to the other. The scanning module scans the reference backing member and the original and successively obtains a first reference image signal representative of an image of the reference backing member, a first image signal representative of an image of the first document, a second reference image signal representative of the image of the reference backing member and a second image signal representative of an image of the second document. The processing module, coupled to the scanning module, compensates the first and second image signals according to the first and second reference image signals, respectively, to obtain first and second resulting signals.

Abstract: An image scanning apparatus moves a copyboard provided between an original document and three line sensors and the three line sensors relatively to each other at a speed different from the speed of conveying an original document. An in-line correction portion allows three data output by three line sensors to be synchronized so that a foreign object on the copyboard appears at different positions of the original document in chromatic color. A foreign object position detection portion detects a position on the copyboard of a foreign object before an original document is conveyed, and a color determination portion decides a determination pixel for use in determination from a plurality of pixels included in each of scanned data obtained while the original document is conveyed, based on the position of the foreign object, and determines whether the original document is color or black-and-white based on the determination pixel.
