Abstract

Digital image capture and processing engine of modular design and employing an optical waveguide structure for collecting and guiding LED-based illumination during object illumination and imaging operations. The digital image capture and processing engine also includes apparatus for automatically controlling the duration of illumination produced from LED illumination arrays during object illumination and imaging operations. Such automatic illumination control involves measuring the amount of illumination to which the object be imaged has been exposed, and controlling the duration of illumination produced from the LED illumination arrays based on such measurements during each object illumination and imaging operation. By virtue of the present invention, the digital image capture and processing engine ensures the reliable formation and detection of high quality images in diverse application environments in the digital image capture and processing engine can be used.
