ABSTRACT:
An image reader operative to correct the decay of image caused by an optical imaging system comprises position detection means for detecting the position of an image signal on an image sensor, by which the image signal is produced, along its scanning direction, imaging performance setting means for setting imaging performance information of the optical imaging system for the position of image signal detected by the position detection means, and decay correction means for correcting the decay of image signal in accordance with the imaging performance information set by the imaging performance setting means. For a color image reader, the imaging performance information is set by the imaging performance setting means for each color component detected by a color component detection means, and decay correction means corrects the decay of image signal of each color component.
