Abstract

An image reading apparatus includes a conveyance unit and a reading unit. Based on read image data from the reading unit, a tilt amount of an edge of a document on a leading edge side in a conveyance direction in which the document is conveyed is decided. If the decided tilt amount exceeds a first threshold where a setting that performs document digitalization with respect to the image data, notification is given of information indicating that reading of the document for the document digitalization has failed. If the decided tilt amount is smaller than the first threshold, skew correction is executed for correcting the tilt amount based on the decided tilt amount with respect to the image data, and the document digitalization is executed with respect to the image data for which the skew correction has been executed.
