Abstract
An illumination device for an image capture system according to one example embodiment includes an integrating light pipe having an input face and an output face. The integrating light pipe is positioned to receive light from a light source at the input face and transmit the light at the output face. A projection element is positioned to focus the light from the output face to a document plane to be imaged by an image sensor. A uniformity correction device is positioned to attenuate the light from the output face so that the light has a substantially uniform intensity at the image sensor and a less uniform intensity at the document plane than at the image sensor.
