Abstract
A scanner includes a scanning module, a processor and an output port. The scanning module scans a document to generate a first signal representative of a composite visible light image of the document and a background element, and a second signal representative of a transmitting light image transmitting through the document. The processor generates a first final image file having first pixels and first complementary pixels according to the first signal, and generates a second final image file having second pixels and second complementary pixels according to the second signal. The first pixels are representative of a visible light image of the document. The first complementary pixels are representative of a remaining visible light image other than the document. The second pixels are representative of a transmitting light image of the document. The second complementary pixels are representative of a remaining transmitting light image other than the document. The output port outputs the first and second final image files to an external device.
