Abstract
A hand-supportable digital image capture and processing system including a hand-supportable housing having an imaging window. A printed circuit (PC) board is mounted in the hand-supportable housing, and has front and rear surfaces and a light transmission aperture formed centrally therethrough. An image formation and detection subsystem has image formation optics for projecting a field of view (FOV) through the imaging window and upon an object within the FOV, and an area-type image detection array for forming and detecting 2D digital images of the object during object illumination and imaging operations. A first FOV folding mirror is supported above the rear surface of the PC board over the light transmission aperture, and a second FOV folding mirror is supported above the rear surface of the PC board and over the area-type image detection array. These mirrors fold and project the FOV through the light transmission aperture and the imaging window. An automatic targeting illumination subsystem is disposed in the hand-supportable housing, and has a plurality of visible light sources mounted on the rear surface of the PC board for generating a targeting illumination beam, which refle…
