Provided are an image reading apparatus and the like for accurately determining the position where an extraneous substance exists. An image reading apparatus comprises: a first unit having an image capture section for capturing a first image and a second image; a second unit having a reference member placed at a position opposed to the image capture section; a conveying mechanism for conveying an original between the first unit and the second unit such that a front end of the original is in contact with one of the first unit and the second unit; an extraneous substance determination unit that determines whether an extraneous substance is included in the first image and the second image; and a position determination unit that, if an extraneous substance is included in the first image, determines whether the position where the extraneous substance exists is on the first unit side or on the second unit side, on the basis of whether the extraneous substance is included in an area of the second image corresponding to an area of the first image in which the extraneous substance is included. The first image is an image obtained by capturing an image of the reference member, while the second image is an image obtained by capturing an image of the reference member after the first image is captured and further the original is conveyed thereafter.
An image reading apparatus comprising:
A control method of an image reading apparatus including a first unit including an image capturing device for capturing a first image and a second image, a second unit including a reference member provided at a position facing the image capturing device, and a conveyance mechanism for conveying a document between the first unit and the second unit so that a leading edge of the document comes into contact with one of the first unit and the second unit, the method comprising:
A computer-readable, non-transitory medium storing a computer program, wherein the computer program causes an image reading apparatus including a first unit including an image capturing device for capturing a first image and a second image, a second unit including a reference member provided at a position facing the image capturing device, and a conveyance mechanism for conveying a document between the first unit and the second unit so that a leading edge of the document comes into contact with one of the first unit and the second unit, to execute a process, the process comprising:
