Abstract:
1. An optical code scanner system for reading at least one optical code comprising: an imager module for acquiring a series of at least one frame of image data, image data of respective frames including an array of pixel data corresponding to imaging of a field of view of the imager module; an aiming assembly having at least one light source for generating at least one beam forming an aiming pattern visible in the field of view; an aiming controller for controlling the aiming assembly for controlling generation of the aiming pattern during acquisition of at least one frame of image data in response to receipt of an actuation signal indicating initiation of a read operation; an optical code selector module executable on at least one processor for performing in accordance with a read operation processing of at least a portion of a first frame of image data acquired while the aiming pattern was generated for determining a location of a pixel of the array of pixel data that is a digital representation of a photosensitive sensor pixel as illuminated by the aiming pattern during acquisition of the first frame, wherein the photosensitive sensor pixel is included in the imager module for imaging the field of view of the imager module; and processing of at least a portion of a second frame of image data of the at least one frame of image data acquired while the aiming pattern was not generated, including selecting at least one optical code acquired in the acquired image data that is located at a respective location, wherein the respective location meets a predetermined condition relative to a second digital representation of the photosensitive sensor pixel in the second frame of image data as determined utilizing the determined location, and providing the selected at least one optical code for further processing in accordance with the read operation, wherein the second frame of image data does not include the image of the aiming pattern.
