Abstract
A multi-mode scanning device for scanning an original includes a background element, a first light source, a second light source and an optical module. The first light source outputs visible light to irradiate the background element and the original to generate first light and second light, respectively. The second light source outputs invisible light to irradiate a combination of the background element and the original to generate third light and fourth light, wherein the background element reflects the invisible light. The optical module receives the first to fourth light and generates sensing signals representative of visible light information and invisible light information of the original. The original is disposed between the background element and the optical module. The first light source, the second light source and the optical module are disposed on a same side of the background element.
