Abstract
A hand-supportable digital imaging-based bar code symbol reading system comprises: an automatic object presence detection subsystem; an image formation and detection subsystem having an area-type image sensing array with a field of view (FOV); a LED-based illumination subsystem having an LED illumination array for producing a field of narrow-band illumination within the FOV; an automatic light exposure measurement and illumination control subsystem; an image capturing and buffering subsystem; an image-processing bar code symbol reading subsystem; an input/output subsystem; and a system control subsystem for controlling the subsystems. The image-processing bar code symbol reading subsystem has a mode of image processing, wherein a captured digital image is automatically processed along a set of parallel virtual scan lines spaced-apart by a number of pixel-offset distances proportional to the maximum pixel height of the region of interest (ROI) in the captured digital image containing a bar code symbol.
