A digital image capture and processing system includes a housing having an imaging window with an illumination-focusing lens structure integrated therewithin. A printed circuit (PC) board is mounted in the housing and has a front surface, a rear surface, and a light transmission aperture spatially aligned with the imaging window. An area-type image detection array is mounted on the rear surface of the PC board. A linear array of light emitting diodes (LEDs) is mounted on the front surface of the PC board, adjacent the light transmission aperture and aligned with the illumination-focusing lens structure. The LEDs produce a plurality of illumination beams which are transmitted through the illumination-focusing lens structure to generate a field of illumination that is projected within the FOV of the system. Illumination reflected and/or scattered off an object within the FOV is retransmitted through the imaging window and the light transmission aperture, and detected by the area-type image detection array.
