1. A method for detecting tape on a document, the method comprising:
- capturing a first image of a document, the first image captured while at least a portion of the document is subjected to a first electromagnetic radiation;
capturing a second image of the document, the second image captured while at least a portion of the document is subjected to a second electromagnetic radiation; and
comparing the first image to the second image to determine whether tape is adhered to the document;
wherein capturing the first image of the document comprises capturing a first plurality of line images of the document to form the first image, and wherein capturing the second image of the document comprises capturing a second plurality of line images of the document to form the second image, andwherein each line image is an image of a vertically spread line of sight of a segment of the document that is less than a whole of the document.

15. An apparatus for detecting tape on a document, the apparatus comprising:
-
a first electromagnetic radiation source to emit a first electromagnetic radiation toward a document; a second electromagnetic radiation source to emit a second electromagnetic radiation toward the document; an imaging device to capture a first image and a second image of the document, each of the first image and the second image being captured while electromagnetic radiation from at least one of the first electromagnetic radiation source or the second electromagnetic radiation source is emitted toward the document; and a controller to compare the first image to the second image to determine whether tape is present on the document; wherein the first image comprises a first plurality of line images of the document, and wherein the second image comprises a second plurality of line images of the document, and wherein each line image is an image of a vertically spread line of sight of a segment of the document that is less than a whole of the document. - View Dependent Claims (16, 17, 18, 19)
