System and method for decoding optical codes read by an imager-based optical code reader

摘要

A system and method for reading an optical code is provided. The method comprises the steps of imaging at least one target, including acquiring and processing image data corresponding to a series of at least one frame; storing image data corresponding to respective acquired frames of the at least one frame, including at least image data corresponding to a current frame (Frame(N)) and image data corresponding to a previous frame (Frame(N-1)); receiving an actuation signal during Frame(N) indicating initiation of a read operation; retrieving at least a portion of the image data corresponding to Frame (N-1); and performing a decode operation on the retrieved image data.
