Abstract
A digital image capture and processing system comprising an illumination measurement subsystem for measuring the level of illumination at a particular region of the field of view (FOV) of the system during object illumination and imaging operations, and producing and storing an illumination measure for achieving a desired spatial intensity in a digital image to be formed and detected by the image formation and detection subsystem. An illumination control subsystem uses the illumination measure to control a LED-based illumination array during object illumination and imaging operations. A programmed image processor supports an image-processing based illumination metering program, as well as processes digital images formed and detected by the image formation and detection subsystem so as to read or acquire information graphically represented in the digital images. A computing platform supports the implementation of one or more of the subsystems above, and includes memory for storing at least one code symbol reading application.
