Hand-supportable digital image capture and processing system having a printed circuit board with a light transmission aperture, through which the field of view (FOV) of the image detection array and visible targeting illumination beam are projected using a FOV-folding mirror
First Claim
1. A hand-supportable digital image capture and processing system comprising:
- a hand-supportable housing having an imaging window;
a printed circuit (PC) board mounted in said hand-supportable housing, and having a front surface and a rear surface and a light transmission aperture formed centrally through said PC board;
an image formation and detection subsystem, disposed in said hand-supportable housing, and having image formation optics for projecting a field of view (FOV) through said imaging window and upon an object within said FOV, and an area-type image detection array for forming and detecting one or more 2D digital images of the object within said FOV during object illumination and imaging operations;
a first FOV folding mirror disposed in said hand-supportable housing, and supported above the rear surface of said PC board and over said light transmission aperture, and a second FOV folding mirror supported above the rear surface of said PC board and over said area-type image detection array, and cooperating with said first FOV folding mirror, for folding and projecting said FOV through said light transmission aperture and said imaging window;
a LED-based illumination subsystem, disposed in said hand-supportable housing, for generating and projecting a field of illumination through said light transmission aperture and said imaging window and into said FOV so that light transmitted through said imaging window towards said object is reflected off said object and detected by said area-type image detection array;
an automatic targeting illumination subsystem disposed in said hand-supportable housing having a plurality of visible light sources mounted on the rear surface of said PC board, for generating a visible targeting illumination beam which is reflected off said first FOV folding mirror and projected through said light transmission aperture and said imaging window and into a portion of said (FOV) extending outside of said hand-supportable housing; and
an automatic illumination control subsystem, disposed in said hand-supportable housing, for controlling the operation of said LED-based illumination subsystem during object illumination and imaging operations, so that said visible targeting illumination beam is momentarily ceased when said LED-based illumination subsystem produces said field of illumination within said FOV.

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. An automatic targeting illumination subsystem is disposed in the hand-supportable housing for projecting a targeting illumination beam into a portion of the FOV extending outside of the hand-supportable housing.
