ABSTRACT:
A method of illuminating objects on a countertop surface using an automatically-triggered digital image capture and processing system having a single array of LEDs disposed near and behind the upper edge portion of its imaging window, which is provided with an illumination-focusing lens structure integrated therein. During object detection, illumination and imaging operations on the countertop surface, typically at a retail point of sale (POS) station, visible illumination generated by the LEDs is focused and projected by the illumination-focusing lens structure so that the system maintains its illumination rays substantially within the field of view (FOV) of said system, and above which the field of view (FOV) of human operator and spectators are positioned, so that the field of illumination extends substantially across the working distance of the FOV of the system, and in a way to illuminate objects located anywhere within the working distance of said system, while minimizing annoyance to the system operator, as well as others in the vicinity thereof during system operation.
