Claim One:
1. A digital image capture apparatus configured to capture an image of a document at least partially illuminated by ambient light, the apparatus comprising: an image capture device comprising a detector adapted to capture an image of said document; an illumination source for illuminating said document, a detector read-out circuit for capturing image data from said detector in response to a control signal; a controller for controlling said detector read-out circuit and said illumination source, wherein said controller provides a first control signal to said read-out circuit to capture a first image of said document when illuminated by said illumination source at a first intensity and by said ambient light to produce a first image, and wherein said controller further provides a second control signal to said read-out circuit to capture a second image of said document when said document is illuminated by said illumination source at a second, lower, intensity and by said ambient light, said second, lower, intensity having a value greater than or equal to zero intensity but less than the first intensity; and a processor arranged to process said first captured image with said second captured image to produce a final image of said document.
