Abstract
According to an embodiment, an image reading device includes a photoelectric conversion unit, a white reference plate, a rotation unit, and a control unit. The photoelectric conversion unit includes an image reading sensor which converts light from an imaging position into image data. The white reference plate has a reading range which is a white reference value. The rotation unit rotates the photoelectric conversion unit so as to come to an angle at which a plurality of portions in the reading range of the white reference plate become imaging positions. The control unit sets a white reference value using a plurality of pixels on the white reference plate which are read using the photoelectric conversion unit which is rotated using the rotation unit.
