An image reading device (100) includes a blank elimination processing portion (330) that performs blank elimination processing for eliminating image data of an original document if a preset blank detection area (BA) in the original document is blank and a frame erasure processing portion (330) that performs frame erasure processing for correcting image data of an original document so that any image in an area other than a preset effective image area (PA) in the original document does not appear. The blank elimination processing portion (330) performs resetting in which a superimposition area where the preset blank detection area (BA) and the preset effective image area (PA) are superimposed on each other is set as a new blank detection area (BA1). |
