    摘要： 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).

    摘要： Methods and systems are disclosed for processing of 2-D images of optical code symbols (30, 72) having information bearing characteristics in predominantly a single dimension (such as a linear barcode). In a preferred system, pixel summing or averaging is used to generate virtual scan lines (105, 106, 171, 172) for imaging of encoded symbols to improve the signal to noise ratio (SNR) of the resulting virtual scan lines. For example, pixel summing or averaging of an imaging array may be performed in a direction orthogonal to the virtual scan line direction in order to increase the SNR of the virtual scan line signal over what can be achieved with virtual scan lines created using a single image pixel for each virtual scan line pixel. The increased SNR offered by this technique of pixel summing or averaging of an imaging array may allow capture of images with reduced exposure time, enabling capture of images of objects moving at high speed without the necessity of high intensity light sources.

    摘要： In one form, an imaging system (100) comprises an imager (130) that forms an image of an object (90) in a field of view, a rotationally symmetric lens assembly (110) disposed between the imager (130) and the object (90), and an equalizer (156). The rotationally symmetric lens assembly (110) provides increased collection efficiency for a given depth of field, whereby the rotationally symmetric lens assembly (110) causes aberration, compared to a well-focused lens. The rotationally symmetric lens assembly (110) comprises a front negative lens (112), a rear positive lens (118), and an aperture (116) positioned between the front and rear lenses (112,118). The equalizer (156), which is connected to the imager (130), receives image data and at least partially compensates for the aberration caused by the rotationally symmetric lens assembly (110).

    摘要： A data reader preferably includes an imaging device that operates on a rolling reset basis to capture images of a moving target (540). Images of moving targets (540) are preferably analyzed to determine the ambient light intensity, and a processor (470) in the data reader preferably adjusts operation of the imager and of a light source (460) based on the intensity of the ambient light. Other data readers may use an imager with a mechanical shutter (1200) that is designed for rapid, frequent operation.
