Abstract
An image-capturing apparatus includes an image-acquiring unit which acquires an image that is captured by photographing a photographic subject which is laid on an arbitrary place, a difference image producing unit which produces a difference image between the captured image that is acquired by the image-acquiring unit and an image which is captured before the photographic subject is laid, a contour extraction unit which extracts contour information of the photographic subject from the difference image that is produced by the difference image producing unit, and an image conversion unit which corrects a distortion of the captured image on the basis of the contour information that is extracted by the contour extraction unit.
