Abstract
A digital image capture and processing system including a housing having an imaging window; and an image formation and detection subsystem with an area-type image detection array having a periodic snap shot mode of the operation supporting the periodic occurrence of snap-shot type image acquisition cycles at a high-repetition rate, during object illumination and imaging operations. The system also includes an illumination subsystem, with a LED illumination array, for producing a field of illumination within the FOV, and illuminating the object detected in the FOV. In the illustrative embodiment, the time duration of illumination of an object within the FOV by the illumination subsystem while the area-type image detection array detects each 2D digital image frame of the object formed on the area-type image detection array, is substantially equal to the time duration that the digital image processing subsystem is allowed to process the detected 2D digital image frame and read a 1D and/or 2D code symbol graphically represented therein.
