摘要： An ambient illumination shielding apparatus for an imaging-based scanner adapted to read direct part marking (DPM) bar codes. The shielding apparatus includes an illumination shield extending from a housing of the scanner and extending along at least a portion of a path of travel of an aiming pattern generated by an aiming apparatus of the scanner. The shield passes illumination within a predetermined wavelength range and impedes passage of illumination outside of the predetermined wavelength range. The predetermined wavelength range of the shield includes a wavelength range of the aiming pattern generated by the aiming apparatus. The shielding apparatus further includes a filter disposed in proximity to an imaging system of the scanner and passing illumination within a predetermined wavelength range to the pixel array and impeding the passage of illumination outside of the predetermined wavelength range. The predetermined wavelength range of the filter includes a wavelength range of an illumination system of the scanner.

摘要： Processing an analog electrical signal containing information representative of reflected light from indicia including regions of different light reflectivity, wherein the analog electrical signal contains edge transitions corresponding to boundaries between adjoining regions of different light reflectivity of the indicia. The edge transitions of at least a part of the analog electrical signal are analyzed to determine a level of blur in that part of the electrical signal. Based on the determined level of blur, one of a plurality of different techniques is selected for processing that part of the electrical signal to produce a digitized electrical signal in which transitions in the digital level of the signal correspond to boundaries between adjoining regions of different light reflectivity of the indicia.

摘要： A miniature imager for reading target images. The optical and electrical systems of the miniature imager are optimized to reduce one or more dimensions or the volume of the imager. In accordance with one embodiment the pixel pitch and focal length are decreased for that of a larger imager to maintain a comparable field of view for each pixel. The decreased pixel pitch allows the area of the aperture and the instantaneous field of view of the pixel to remain constant while decreasing the overall size of the imager. In other embodiments apparatus and techniques reduce and/or eliminate the need for illumination of a target by the imager thereby reducing the overall power consumed by the imager and/or its overall size. The imager has an increased working range.

摘要： Optical image readers have a two-dimensional image sensor and an auto-discrimination function. The auto-discrimination function identifies optical codes by type for pixel clusters and, in some cases, tilt angle and start/stop coordinates. The clustered pixel data is passed to an appropriate decoder identified by the auto-discrimination function based upon a likelihood that the cluster contains an optical code of a particular type. Line drawing technique provide for adequate sampling of the clustered pixel data code based on the tilt angle of the code relative to an image sensor array.
