摘要： Digital-imaging based code symbol reading system employing a micro-computing platform supporting an event-driven multi-tier modular software architecture the system comprises: an image formation and detection subsystem; an illumination subsystem; an illumination control subsystem; an image processing subsystem; an input/output subsystem; and a system control subsystem. The image formation and detection subsystem has an area-type image sensing array for detecting digital images of objects formed thereon by image formation optics providing a field of view (FOV) for the system. Within the FOV of the image formation and detection subsystem, the illumination subsystem produces a field of illumination that illuminates the object during the image capture mode of operation, and one or more 2d digital images thereof are detected by an area-type image sensing array. A micro-computing platform is provided for implementing the digital image processing subsystem, the input/output subsystem and the system control subsystem. The micro-computing platform includes a microprocessor, a memory architecture, and a three-tier modular software architecture characterized by an operating system layer, a system core layer, and an application layer and responsive to the generation of a triggering event within the digital-imaging based code symbol reading system. Triggering events can be generated by an automatic object detector or a manually actuated trigger switch.

摘要： A digital-imaging based code symbol reading system comprising an image sensing array with a field of view (FOV), an illumination subsystem with an LED illumination array, an automatic illumination measurement subsystem, an illumination control subsystem, and programmed imager processor supporting an image-processing based illumination metering program. The automatic illumination measurement subsystem automatically measures the illumination level at a particular region of the FOV and determines the illumination duration necessary to achieve a desired spatial intensity in the detected digital image. The illumination metering program automatically analyzes and measures, in real-time, the spatial intensity distribution of the digital image and determines whether or not a corrected illumination duration is required or desired when detecting the next or subsequent digital images, during the current or subsequent object illumination and imaging cycle. The previously determined illumination duration is over-written with the corrected illumination duration, which is used to drive the illumination subsystem and form and detect one or more subsequent digital images of the illuminated object.

摘要： A portable digital image capturing and processing system comprising: an image formation and detection subsystem; a narrow-band illumination subsystem; a narrow-band transmission-type optical filter subsystem; an automatic light exposure measurement subsystem; and an automatic illumination control subsystem. The image formation and detection subsystem has an area-type image sensing array for detecting digital images of objects formed thereon by image formation optics providing a field of view (FOV) for the system. Within the FOV of the image formation and detection subsystem, the narrow-band illumination subsystem produces a field of narrow-band illumination consisting essentially of a narrow band of wavelengths of visible illumination. The narrow-band transmission-type optical filter subsystem transmits substantially only the narrow band of wavelengths of visible illumination produced from the narrow-band illumination subsystem, and rejects all other optical wavelengths outside the narrow band however generated by ambient illumination sources. The automatic light exposure measurement subsystem employs a photo-detector operated independently from the area-type image sensing array, for automatically measuring the light exposure incident upon a selected portion of the FOV, and producing an electrical signal representative of the light exposure measurement. Only when all sensor elements in the image-sensing sensing array are activated and in state of integration, then narrow-band illumination is produced for illuminating objects in FOV of the system and simultaneously detected by a photo-detector for measuring light exposure within the FOV, and also by an area-type image sensing array for detecting a digital image of said illuminated object.
