Abstract: A data reader (50) such as for example an imaging reader with a CCD or CMOS imager or the like, that acquires an image of an item to be read. A certain type of sensor (5) has been found to exhibit different outputs depending upon the light intensity level, namely a standard output (20) whereby the sensor outputs a signal corresponding to the image collected; and an inverted output (30) whereby the sensor outputs an inverted signal when the light intensity highly saturates the sensor. Taking advantage of this inverted output, systems and methods are then employed by the data reader to convert or otherwise re-invert this inverted signal in order to read an optical code that, for example, might otherwise have been above the upper exposure limit of the sensor/reader and thus not decodable.

Abstract: An optical code or other data reading device (100) includes a color image sensor array (102) positioned to sense light reflected from an object (114), and to produce image data. In one configuration, the sensor array has multiple sets (e.g., first set (104) and second set (106)) of sensor elements that are sensitive to corresponding visible wavelength bands of light (e.g., first and second wavelength bands), the sets also being sensitive to light within an infrared wavelength band. An artificial illumination source (108) is positioned to illuminate the field of view (116) with light that is reflected off the object toward the sensor array, the illumination source being operable to produce infrared light having wavelengths within the infrared wavelength band so that, upon illumination, at least some sensor elements of each of the sets are sensitive to the infrared light and contribute to production of the image data.

Abstract: An integrated scanner and scale is provided having a thin profile and incorporating imaging technology to scan and read optical codes. The scanner-scale is sufficiently thin to allow a cash drawer to fit beneath the scanner-scale in a check stand. Side imagers are positioned and configured to scan multiple sides of an item. The field of view (FOV) of each imager defines at least a portion of a scan volume, wherein scanning is nearest to optimal. On or more imagers can be positioned on the checker side and the customer side, such that an optical path (or a portion thereof) from the scan volume to the one or more imagers is positioned entirely above a platter of the scanner. Mirrors fold and direct the optical path to direct the FOV of a bottom imager such that the bottom imager is positioned sufficiently close to the platter to allow the scanner-scale to have a thin profile.

Abstract: Various improved imager-based optical code readers (500,800) and associated methods (3200,3300) are disclosed herein. According to one embodiment, an imager-based method reads an optical code (which may be, for example, a linear optical code such as a bar code) on an object in a viewing volume. The method comprises dividing (3310) an image plane (400) into a plurality of strip-shaped sections, viewing (3320) the object in the viewing volume from a plurality of perspectives, forming (3340) a plurality of strip-shaped images corresponding to the plurality of perspectives, respectively, thereby creating a composite image containing data from a plurality of perspectives, and processing at least a portion of the composite image so as to ascertain the information encoded in the optical code on the object in the viewing volume. Certain embodiments can mimic the performance of a laser-based scanner (100) without a laser or moving parts but instead utilizing an electronic imaging device such as an imager (508,808).

Abstract: An imaging system (100,200) comprises a rolling-reset imager (110) that forms an electronic image of an object (160), a light source (130) illuminating the object (160) with pulsed light, and a bandpass optical filter (170) disposed between the object (160) and the rolling-reset imager (110). The pulsed light has an illumination frequency spectrum and an illumination pulse width defining an effective exposure time for forming the image of the object. The bandpass optical filter (170) has a frequency pass band permitting transmission of a significant portion of the illumination frequency spectrum while at least approximately inhibiting transmission of at least some light having frequencies outside the illumination frequency band.
