Disclosed herein is a barcode reading system that includes an image decoding system, a communication interface, and an image sensor system package. The image decoding system may include a processor, memory, and a decoder stored in the memory. The image sensor system package may be coupled to the image decoding system via the communication interface. The image sensor system package may include a photo sensor array and pre-processing circuitry. The photo sensor array may be configured to capture image frames at a first speed. The pre-processing circuitry may be configured to perform one or more operations on the image frames captured by the photo sensor array.

The first speed may be greater than the second speed.

A code reading device for the parallel reading of a plurality of codes on a plurality of objects arranged next to one another is provided that has a camera unit having at least one camera head for recording an image of the objects, a control and evaluation unit that is configured to localize code zones of the codes in the image and to read the code information of the codes, and a display unit to present the image and to mark the read codes and/or objects having read codes, Here a hand reading unit for reading codes is provided to subsequently read codes not read by means of the camera unit and to transfer the subsequently read code information to the control and evaluation unit.

A method and apparatus for correcting auto-exposure settings of a barcode reader based on modifying an auto-exposure region at a barcode reader for decoding a barcode in response to identifying a barcode and failing to decode the barcode due to incorrect initial exposure parameters, wherein the modified auto-exposure region is based at least in part on the barcode location.

A method and apparatus for the focus stabilization of an imaging system with variable focus lenses is disclosed herein. As example imaging system includes a variable focus (VF) lens for imaging an object of interest (OOI), a controller configured to provide a voltage to the VF lens, an imaging sensor, and a processor. The processor obtains a calibration parameter, and the imaging system obtains a plurality of images of the OOI. The processor identifies a region of interest of one or more of the images, and an alignment parameter is determined from the images. The processor then determines a tuning parameter from comparing the determined alignment parameter with the obtained calibration parameter. The controller tunes the VF lens according to the determined tuning parameter.

A barcode reader configured to capture interleaved frame types optimized for vision capture and barcode capture are disclosed herein. An example barcode reader is configured to operate in a pre-determined repetitive pattern of capturing a first frame and capturing a second frame over a reading cycle having a fixed duration after a triggering event, wherein the first frame is captured over a first exposure period having a first duration, and the second frame is captured over a second exposure period having a second duration, and wherein the first frame is associated with a first brightness parameter, and the second frame is associated with a second brightness parameter.

An encoded information reading (EIR) terminal can comprise a microprocessor, a memory, and an EIR device including a two-dimensional imager. The EIR device can be configured to output raw message data containing an encoded message and/or outputting a decoded message corresponding to an encoded message. The EIR terminal can be configured, responsive to acquiring an image containing decodable indicia, to pre-process the acquired image and transmit the pre-processed image to an external decoding computer for decoding the decodable indicia.

A method and apparatus for correcting auto-exposure settings of a barcode reader based on modifying an auto-exposure region at a barcode reader for decoding a barcode in response to identifying a barcode and failing to decode the barcode due to incorrect initial exposure parameters, wherein the modified auto-exposure region is based at least in part on the barcode location.

An apparatus for controlling a depth of field for a reader in a vision system includes a dual aperture assembly having an inner region and an outer region. A first light source can be used to generate a light beam associated with the inner region and a second light source can be used to generate a light beam associated with the outer region. The depth of field of the reader can be controlled by selecting one of the first light source and second light source to illuminate an object to acquire an image of the object. The selection of the first light source or the second light source can be based on at least one parameter of the vision system.

The parameters of an optical code are optimized to achieve improved signal robustness, reliability, capacity and/or visual quality. An optimization program can determine spatial density, dot distance, dot size and signal component priority to optimize robustness. An optical code generator employs these parameters to produce an optical code at the desired spatial density and robustness. The optical code is merged into a host image, such as imagery, text and graphics of a package or label, or it may be printed by itself, e.g., on an otherwise blank label or carton. A great number of other features and arrangements are also detailed.
