Abstract:
1. An image reading device, comprising: an image reading portion that reads an original document; a blank elimination processing portion that, based on image data of a page of an original document obtained through the reading by the image reading portion, judges whether or not a preset blank detection area in the page is blank, and performs blank elimination processing for prohibiting a printout of the page if the preset blank detection area in the page is blank; and a frame erasure processing portion that performs frame erasure processing for correcting image data of an original document obtained through the reading by the image reading portion so that any image in an area other than a preset effective image area in the original document does not appear, wherein in a case of having accepted a command to execute both of blank elimination processing and frame erasure processing, when performing the blank elimination processing in a case where the frame erasure processing portion is to perform the frame erasure processing, the blank elimination processing portion performs resetting in which a superimposition area where the preset blank detection area and the preset effective image area are superimposed on each other is set as a new blank detection area, and designates the new blank detection area after the resetting as a target area for blank detection.
