Abstract
An image capture device, such as a scanner, is built including hardware necessary to capture both reflective and transmissive image data from a transparency. The device may associate the two types of data internally or rely on other hardware, such as a controlling computer, to do the association of the two quantities of data. In one possible embodiment, the device would include the ability to perform optical character recognition (OCR) of the reflective data (or the transmissive data, if desired), converting to a type of text format any printing on the transparency.
Claims24
An image capture device comprising:
- a light source configured to illuminate at least an opaque portion of an object in an imaging plane, and at least a transmissive portion of an object in said imaging plane,
- a transmissive sensor positioned relative to said light source to capture transmissive image data from said transmissive portion of an object;
- a reflective sensor positioned relative to said light source to capture reflective image data from said opaque portion of an object, wherein said transmissive image data and said reflective image data are captured concurrently;
- and
- an association device that associates said reflective image data with said transmissive image data.
