In an image processing apparatus, a condition for detecting a print position deviation on a print medium in a printed material is set. Based on the condition, data obtained by reading the print medium for the print position deviation is inspected. In the condition, in a case where a width of the print medium is larger than a readable width for reading the print medium, a settable range is small relative to a case where the width of the print medium is smaller than the readable width.

Medium conveying apparatus for determining whether a conveyed medium is ID card

A reading portion generates an original image including an image of a document sheet. A first document sheet end detection portion, in a case where the thickness of the document sheet is equal to or greater than a threshold value, identifies a peripheral edge shape of the document sheet by detecting a shadow portion that occurs at a peripheral edge portion of the document sheet in the original image. A second document end detection portion, in a case where the thickness of the document sheet is less than a threshold value, identifies the peripheral edge shape based on a specification by the user. A document sheet size determination portion determines a size of the document sheet according to a result of shape identification by the first document sheet end detection portion or a result of shape identification by the second document sheet end detection portion.
