    摘要: The exemplary system requires a 2D barcode be located on an object, a portion of which is to be captured in an image. The module size of the 2D barcode is chosen to match the smallest feature to be preserved on the output image. While the target is moving with respect to the imager the 2D bar code is also moving and the resulting image is degraded. The imager will properly decode the 2D barcode only if the bar code is stationary (or moving very slowly) and hence will provide an acceptable image in the region of the 2D bar code.

    摘要: Aiming of an imaging reader at direct part markings (DPM) on workpieces is enhanced by emitting an aiming light beam during aiming, and by optically modifying the aiming light beam during the aiming to generate an aiming light pattern having an outer bright region illuminated by the aiming light beam and visible to an operator to enable the operator to manually position the bright region to entirely surround at least part of the DPM, and an inner dark region not illuminated by the aiming light beam and surrounded by the bright region. The dark region contains the part of the DPM code to be imaged and read by the reader after the aiming.

    摘要: Processing an analog electrical signal containing information representative of reflected light from indicia including regions of different light reflectivity, wherein the analog electrical signal contains edge transitions corresponding to boundaries between adjoining regions of different light reflectivity of the indicia. The edge transitions of at least a part of the analog electrical signal are analyzed to determine a level of blur in that part of the electrical signal. Based on the determined level of blur, one of a plurality of different techniques is selected for processing that part of the electrical signal to produce a digitized electrical signal in which transitions in the digital level of the signal correspond to boundaries between adjoining regions of different light reflectivity of the indicia.

    摘要: A method of identifying or authenticating a product by providing an analog identification indicium including a randomized pattern of identification features on a first part of the product wherein one or more attributes of the randomized pattern of identification features correspond to an item identifier. A digital identification record is provided on a second part of the product including an encoded digital version of the item identifier, the first and second parts being separable when the product is used. The randomized pattern of identification features of the analog identification indicium is read and decoded to generate an item identifier and the digital identification record is read and decoded to generate an item identifier. A blur analysis is performed on the analog identification indicium and the amount of blur is compensated for during processing. The product is deemed authentic if the item identifier from the analog identification indicium substantially matches the item identifier from the digital identification record.

    摘要: An optical code reading system having an auto-exposure system for use with a variable resolution imaging sensor in which very low resolution images are used to determine exposure parameters is presented. The very low resolution images can be transferred much faster than high resolution images which results in a very fast auto-exposure system. The optical code reading system further includes an optical zoom system for zooming in and out of a target without the use of any moveable components. The optical zoom system makes use of a binning and/or subsampling feature of the imaging sensor for zooming in and out of the target. High-speed decoding methodologies are also presented for the optical code reading system. One decoding methodology utilizes low resolution images for performing high-speed decoding. Other methodologies utilize low resolution images and higher resolution images, if the optical code imaged by the low resolution images is not decoded successfully.
