Claim Text:
1. An object imaging assembly comprising: a source of individual objects which are moved along a given course of travel, and wherein the course of travel has a predetermined width dimension, and opposite first and second sides; an image capturing device which is located on one of the first or second sides of the course of travel, and wherein the image capturing device has a line of sight which extends transversely across the course of travel of the source of objects; a background image reference which is located along the line of sight of the image capturing device, and which is positioned on the opposite side of the course travel relative to the image capturing device; and a first electromagnetic radiation emitter which is located on one of the first or second sides of the course of travel and which, when energized, emits a source of electromagnetic radiation which is projected across the course of travel of the objects, and which is reflected, at least in part, from the respective objects as they move across the line of sight of the image capturing device, and wherein the source of objects passing through the emitted electromagnetic radiation creates individual shadows which are formed in a location which is spatially separated from, and outside the line of sight of the image capturing device, and wherein the background image reference has a given color, and is directly illuminated by a second electromagnetic radiation emitter.
