摘要

An image scanning apparatus according to the invention includes: a scanning unit configured to scan each of plural images from plural originals that are inputted; a rotation designating unit configured to designate rotation of the plural images that are scanned, so that an orientation of the plural images that are scanned coincides with a desired image orientation; a first image rotating unit configured to rotate the image that is scanned, in accordance with the designated rotation of the image; an orientation determining unit configured to determine whether the image orientation rotated by the first image rotating unit coincides with the desired image orientation or not; and a second image rotating unit configured to, for an image determined as not coinciding by the orientation determining unit, further rotate the orientation of the image so that the orientation coincides with the desired image orientation.
