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.
