  • Functional aiming system for an automatic data collection device, such as an image acquisition device
    Patent number: 7967206
    Abstract: An automatic data collection device is provided for reading barcodes, matrix codes, stacked codes, or other machine-readable symbol. The data collection device generates an aiming beam that serves a dual purpose of target locating and data acquisition, such as data acquisition using imaging methods. The aiming beam defines the field of view of the data collection device for imaging. The illumination pattern provided by the aiming beam for imaging can have its shape, size, and/or intensity adaptively changed depending on conditions.

  • Detecting barcodes on two-dimensional images using frequency domain data
    Patent number: 7451931
    Abstract: A system and method of detecting a barcode involves obtaining a two-dimensional source image and converting it into a frequency domain image (FDI). Frequency trends in the FDI are then analyzed to determine whether barcode information is present in the FDI. In this way, the presence, location, orientation, size and symbology of a barcode can be quickly and accurately determined.
