20120257371 | ILLUMINATION DEVICE FOR AN IMAGE CAPTURE SYSTEM - 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. | 10-11-2012 |
20130003140 | Image Capture System Having a Folded Optical Path - An image capture system including a platen for receiving a media sheet bearing an image to be captured; an illumination system for illuminating the media sheet; a mirror disposed in optical communication with the platen, for reflecting light from the illumination system reflected from the media sheet; and an optical sensor for receiving the light reflected by the mirror. The interrelationship between the platen, mirror and optical sensor is such that a location of a top edge of the mirror's primary reflection projected onto the platen is lower than a location of a bottom edge of the image's secondary reflection projected onto the platen. In this way, the image captured by the optical sensor is free of secondary reflections. | 01-03-2013 |
