SCANNER, SYSTEM, AND METHOD FOR A SCANNER IMAGING ILLUMINATION FILTER

Abstract:

A scanner is provided having an integrated or retrofitted amber filter placed in front of white illumination LEDs. When an object/item is placed within a field of view of a lens of the scanner, the white illumination LEDs are illuminated and pass through the amber filter, which filters out light in the light spectrum of approximately 340-500 nm. The object/item is illuminated with light approximately above 500 nm and reflected back through a portion of the lens that covers an imaging sensor resulting in an object/item image in the light spectrum approximately above 500 nm, which improves the user experience by removing the glaring blue light component of the white LEDs illumination while not impacting the performance of the object/item recognition when processed for a transaction being conducted at a transaction terminal that is interfaced to the scanner.
