摘要： A system and method are provided for performing a read operation including acquiring a series of frames of image data; processing a first frame of image data including an array of pixel data acquired while an aiming pattern was generated for determining a location L of at least one pixel of the array of pixel data that corresponds to the aiming pattern; and processing a second frame of image data acquired while the aiming pattern was not generated. The processing of the second frame of image data includes the steps of selecting at least one optical code acquired in the second frame of image data that is located at a respective location; wherein the respective location meets a predetermined condition relative to the determined location L; and providing the selected at least one optical code for further processing in accordance with the read operation.
