ABSTRACT:
The scanning method of the invention enables a user to scan transparencies with a duplex scanner having a moveable camera, and a mirror or light source associated with the camera on each side of the document path. The scanner, in its normal mode of operation, is a duplex reflective scanner which means the image, per side, is captured by reflecting light from a light source located on the same side of an opaque flat object as the CCD of the camera that captures the image. In order to scan transparencies, a mechanism is provided which allows an opposing camera light source to be aligned (moved at runtime) with the aperture of the camera opposite the opposing camera light source. This allows the light of the opposing camera light source to project through a transparent object while the opposite camera CCD captures an image of the transparency. The opposite camera, which captures the image, has its light source turned off while in the transparent scanning mode.
