More Information
Summary:In an example embodiment, there is disclosed herein an apparatus comprising first and second light sources, a sensor, and an image processor. The sensor obtains image data from the first and second light sources, wherein the image data from the first light source is a composite image of light passing through the sheet and the near side image data from the second light source is a reflected, near side image. The image processor subtracts the near side image data from the composite image data to obtain far side image data, and can determine textual data on the sheet form either the near side image data, the far side image data, or a combination of the near side image data and the far side image data.
