  • Publication number: 20080041960
    Abstract: An Automatically-triggered digital video-imaging based code symbol reading system providing a high degree of adaptability to ambient illumination levels and having great dynamic range. The system includes an illumination subsystem, having an active illumination mode and an ambient illumination mode. During object illumination and image capturing operations, the exposure quality of a captured frames of digital video image data is analyzed, and based on the results of such exposure quality analysis, system control parameters (SCPs) are automatically reconfigured. In the event that the exposure quality analysis indicates excessive exposure levels in captured frames of digital video image data, then a new set of SCPs is reconfigured, controlling the illumination subsystem to operate in its ambient illumination mode, whereby, ambient illumination is allowed to flood the field of view and form digital images on the image detection array during object illumination and video-imaging operations.

  • Publication number: 20080006698
    Abstract: An automatic digital video image capture and processing system supporting image-processing based code symbol reading during a pass-through mode of system operation at a retail point of sale (POS) station. The system comprises an automatic object direction detection subsystem, disposed in its housing, as well as an illumination subsystem, an image formation and detection subsystem, an automatic illumination control subsystem, a digital image capturing and buffering subsystem, a digital image processing subsystem, and a system control subsystem. During system operation, the automatic object direction detection subsystem automatically detects the presence and direction of movement of the object in the field of view (FOV), and in response thereto, generates a first signal indicating a triggering event and a second signal indicating the direction of movement of the object with respect to the FOV.
