EVALUATION APPARATUS USING UNIFORM ILLUMINATION AND DATA CAPTURE
First Claim
1. An evaluation apparatus for digital data gathering devices that can ensure uniform evaluation results from two or more of said digital data gathering devices, said digital data gathering devices accepting incoming light through a lens, said evaluation apparatus comprising:
- a light shroud having an enclosing wall, said enclosing wall substantially surrounding said lens and extending a predetermined distance outwardly therefrom and defining a distal edge portion;
an illumination source in selective communication with an interior of said light shroud thereby preventing ambient light from entering said interior of said light shroud when a substantial entirety of said distal edge portion of said enclosing wall is in touching contact with an object;
a calibration device arranged within said light shroud, said calibration device selectively reflecting light from said illumination source; and
wherein said evaluation apparatus alters subsequent digital data gathering by said evaluation device in dependence upon said reflected light, thereby ensuring said uniform evaluation results from any of said digital data gathering devices having said calibration device.

Abstract
An evaluation apparatus is proposed for a digital data gathering device that accepts incoming light through a lens of the digital data gathering device. The evaluation apparatus includes a light shroud having an enclosing wall, which substantially surrounds the lens and extends a predetermined distance outward, forming a distal edge portion. An illumination source is provided to be in selective communication with an interior of the light shroud. The light shroud prevents ambient light from entering the interior of the light shroud when a substantial entirety of the distal edge portion of the enclosing wall is in touching contact with an object.

12. A method for uniform evaluation of light entering through a lens of two or more digital data gathering devices, said method comprising the steps of:
-
forming a light shroud to have an enclosing wall, said enclosing wall substantially surrounding said lens and extending a predetermined distance outwardly therefrom, said light shroud further defining a distal edge portion; positioning an illumination source to be in selective communication with an interior of said light shroud; placing a substantial entirety of said distal edge portion of said light shroud in touching contact with an object, thereby preventing ambient light from entering said interior of said light shroud; arranging a calibration device within said light shroud and selectively illuminating said calibration device by said illumination source during an initial exposure operation; and performing subsequent exposure operations of said digital data gathering devices, said subsequent exposure operations enabling said digital data gathering devices to gather digital data pertaining to said object, wherein said digital data is altered in dependence upon said initial exposure operation, thereby ensuring said uniform evaluation results from any of said digital data gathering devices having said calibration device. - View Dependent Claims (13, 14, 15, 16, 17, 18)

19. A method of enabling uniform digital data gathering and evaluation by light entering through a lens of two or more digital data gathering devices, to assist in product matching, said method comprising the steps of:
-
selectively affixing a light shroud to substantially surround said lens of said digital data gathering devices; calibrating said digital data gathering devices in dependence upon an initial illumination and data capture by said digital data gathering device; performing a subsequent illumination and data capture of an object, said subsequent illumination and data capture reflecting a product value of said object; altering said product value of said subsequent illumination and data capture in dependence upon said initial illumination and data capture, thereby ensuring said uniform digital data gathering and evaluation from any of said digital data gathering devices having said calibration device; and searching for products that match said altered product value. - View Dependent Claims (20, 21)
