1. A digital-imaging based code symbol reading system comprising:

  • a housing having a light transmission aperture;

    an image formation and detection subsystem, disposed in said housing, having image formation optics for producing and projecting a field of view (FOV) through said light transmission aperture and onto an 2D image detection array for detecting narrow-area 2D digital images of any objects present within said FOV during object illumination and imaging operations;

    an illumination subsystem, disposed in said housing, including a planar illumination array for producing planar illumination (beam (PLIB) within said FOV, and illuminating said any objects present in said FOV, so that said PLIB reflects off said objects and is transmitted back through said light transmission aperture and onto said 2D image detection array so to form a narrow-area 2D digital image of said objects,wherein said narrow-area 2D digital image consists of an array of pixels formed on said 2D image detection array;

    an image capturing and buffering subsystem, disposed in said housing, for capturing and buffering said narrow-area 2D digital image detected by said image formation and detection subsystem,a digital image processing subsystem, disposed in said housing, for (i) processing the pixels of said narrow-area 2D digital image so as to composite a linear (1D) image, and also (ii) processing said linear (1D) digital image in order to read a code symbol graphically represented in said linear digital image and generating symbol character data representative of said read code symbol.
