Abstract
A multi-imaging scanner (12) and method for imaging indicia (14) located on target objects (16) is featured in the present disclosure. The multi-imaging scanner (12) includes one or more cameras (30) for imaging indicia (14) on target objects (16) and a sensor array (48) associated with each of the one or more cameras (30) for capturing a series of frames (FR1-FR6) within a respective field of view of each of the one or more cameras (30). The multi-imaging scanner (12) further includes a processor (44) coupled the one or more cameras (30) for imaging and decoding the indicia (14) on the target objects (16) captured in the frames by the one or more cameras. The frames (FR1-FR6) include a first frame having a first pre-set exposure time and a second frame having a second pre-set exposure time such that first and second pre-set exposure times are of different duration.
