Abstract
An image reading apparatus includes an original tray, a conveyer, a reading unit, an acquisition unit, one or more processors, an acquisition unit, a setting unit, and a corrector. The acquisition unit is configured to acquire information relating to a length of the original to be read by the reading unit in a main scanning direction orthogonal to the conveying direction, and the setting unit is configured to set an ineffective region based on the information acquired by the acquisition unit, wherein the ineffective region is a region in the main scanning direction of the pixel data which is not to be used for determination of an inclination amount corresponding to an inclination angle, with respect to the main scanning direction, of a side at a leading edge of the original in the conveying direction.
