  • Axial chromatic aberration auto-focusing system and method
    Patent number: 7478754
    Abstract: A system and method utilizing the principles of axial chromatic aberration for auto-focusing an image onto an image sensor are provided. The system and method are particularly suitable for incorporation within an optical code reader. A signal processor analyzes data signals representative of the intensity or magnitude of wavelength components of an impinged image onto the image sensor for determining a value indicative of the focus quality of the impinged image. An actuator controls movement of a lens in accordance with the determination until obtainment of a desired focus quality. A decoder decodes the image having the desired focus quality.

  • Control of specular reflection in imaging reader
    Publication number: 20090001175
    Abstract: Electro-optical reading failure to read indicia due to specular reflection in the return light captured by a solid-state imager is prevented. An illuminator illuminates the indicia during reading with illumination light directed from an illuminating light source. In one embodiment, a controller is operative for detecting saturation in a captured image, and for reducing an intensity of the illumination light upon detection of the saturation. In another embodiment, the controller captures the return light in successive frames, and causes the illumination light to illuminate the indicia only during some of the frames. In yet another embodiment, the controller turns the illumination light on and off at a flash rate, and signals a user by changing the flash rate upon detection of the saturation to move a housing that supports the imager, illuminator and controller.

  • COMPACT AUTOFOCUS BAR CODE READER WITH MOVING MIRROR
    Publication number: 20080290169
    Abstract: The disclosed bar code reader includes an auto-focusing component for rapidly producing in focus images. An imaging system makes use of an aiming pattern that impinges upon the coded indicia of a target. The imaging system includes a light monitoring pixel array and a focusing lens that is fixed with respect to the pixel array for transmitting an image of the target object onto the pixel array. The imaging system also includes a movable mirror mounted for movement along a path of travel to reflect light passing through the focusing lens onto the pixel array. A drive motor moves the mirror relative the lens to adjust a focus of an image of the object formed at the pixel array. An automatic focusing component of the imaging system analyzes the aiming pattern reflected from the target object and projected onto the pixel array by the lens.
