Abstract:
An image reading apparatus capable of efficiently performing shading correction. The image reading apparatus includes a reading unit that is rotatable for reading an original. A CPU causes the reading unit to read, while the reading unit rotates after reading an image of the original, image data for use in correction of the read image. The CPU performs the correction using the image data read by the reading unit.
