Abstract
An imaging device comprises a number of light sources, a camera, a processor and a platen. As an object is moved over the platen each of the light sources illuminates the platen sequentially, with the principal axis of illumination of each light source intersecting the plane of the platen at a different place. The camera captures a series of images of the object, each captured image corresponding to the illumination of the platen by a different light source. The processor then generates a composite image from the series of images that compensates for the reflection of light from the platen associated with the principal axis of illumination.
