  • Publication number: 20050161511
    Abstract: The invention relates to an optical reading system comprising an optical reader and a host processor. In one aspect of the invention, the host processor may be configured to transmit a component control instruction in response to a user input command input by a user of the host processor to remotely control the reader. The optical reader subsequently receives the transmitted component control instruction and executes the component control instruction substantially on receipt thereof. In one embodiment, execution of the component control instruction by the optical reader has the same effect as the reader trigger being manually pulled by a reader operator.

  • Publication number: 20050001035
    Abstract: An optical reader having a picture taking mode and a decode mode. In a picture taking mode, the reader captures and outputs a frame of image data without attempting to decode a decodable symbol in the frame. In the decode mode, the reader captures a frame of image data and attempts to decode a decodable symbol represented in the frame. The reader may have a decode mode in which light from an aiming light source is received by an image sensor.

  • Patent number: 6834807
    Abstract: The present invention relates to an optical reader that includes a color imaging assembly that generates color imaging data. An image analysis circuit determines if the acquired image should be characterized as a color photograph or as including a graphical symbol. A processing circuit processes the imaging data based on the image analysis circuit's determination of whether the image is a graphical symbol or a color photograph. The present invention allows a user to acquire and process both color images and graphical symbols, such as bar codes, text, OCR symbols or signatures. The optical reader of the present invention is also configured to associate an acquired image with at least one other acquired image.

  • Patent number: 6832725
    Abstract: An imaging module in one embodiment includes at least one multiple color emitting light source comprising a plurality of different colored LED dies each independently driveable so that the overall color emitted by the light source can be controlled and varied. The multiple color emitting light source can be controlled so that the color emitted by the light source is optimized for imaging or reading in a present application environment of the module. Further, the module can be configured so that control of the multiple color emitting light source automatically varies depending on a sensed condition, such a color present in a field of view of the module, the distance of the module to a target, and/or a predetermined criteria being met so that feedback is provided to a user. The module in a further aspect can include illumination light sources and aiming light sources which project light in different wavelength emission bands.

  • Publication number: 20040155110
    Abstract: The present invention relates to a method for managing mail/parcel item delivery. The mail/parcel item includes an optical indicia disposed thereon. The method includes capturing a first color image of the item. The first color image is stored in an electronic memory. A second color image of the optical indicia is captured. The optical indicia is decoded to thereby generate decoded data. The first color image is associated with the second color image and/or the decoded data. As a result, the first color image and the second color image and/or the decoded data are linked in the electronic memory. An image is displayed that includes the first color image and at least the decoded data.

  • Publication number: 20040004128
    Abstract: The invention relates to methods and systems for analyzing and decoding image data captured with a one dimensional image sensor using N-bit mathematical methods. The analysis comprises converting a sequence of analog pixel data values to a corresponding sequence of data in an N-bit digital format and processing the data. The data can be analyzed using any or all of filtering, adaptive threshold determination, edge position interpolation, searching for distinctive barcode patterns, and detailed barcode decoding and checking. In alternative embodiments, the data is manipulated using a pre-scan of stored sequences of values. In another embodiment, the data is directly scanned and processed for qualifications, searching for, and decoding barcode patterns.
