An image reading apparatus has a scan quality parameter extraction part, a scan quality evaluation part and a notification part. The scan quality parameter extraction part extracts scan quality parameters representing the quality of a scanned image from image data based on a scan error detection algorithm. The scan quality evaluation part determines whether a scan error occurs, based on the scan error detection algorithm and the scan quality parameters. Also, the notification part notifies a result determined by the scan quality evaluation part to a user.
