摘要： A line-scan imaging camera can scan an object at a near field and a far field using a low F-stop value by reading out different rows on an imager. A line LED provides a line illumination over an object. Additionally, the imaging camera captures the illumination portion of the object through an optical path that includes mirrors that allow folded optics. The optical path is longer than the distance between the object and the camera. A mirror is located close to or adjacent to the line LED to provide efficient illumination and to align the initial leg of the optical path with the line illumination.

摘要： A method for glare reduction may be implemented by a graphical code reader. The graphical code reader includes an optic system, a plurality of light sources, and a control system. The control system is configured to determine that glare is present in an image captured by the optic system by identifying reflection from at least one of the plurality of light sources. The control system may take a corrective action to reduce the glare in subsequent images. The control system may be configured to take a first corrective action if a diffraction pattern is present at a periphery of the glare, and take a second corrective action if a diffraction pattern is not present at the periphery of the glare.

摘要： A method 100 maximizes the contrast between light and dark markings 13 that carry information. The markings are illuminated by a variable output light source 16, and a reflected image is received by a detector 18 and processed by a controller 20. The method calculates a histogram of the reflected image at step 102, and the method determines at step 104 if the histogram has one peak or two peaks. The method increases at step 110 or decreases at step 112 the output of the light source 16 by adding or subtracting a small step amount to or from the current light level of the light source 16. The method 100 is a continuously repeating loop, and the method increases or decreases the light level of the source of illumination with substantially every loop to oscillate about an equilibrium light level that provides maximum contrast.

摘要： A bar code reader 10 includes a housing 20 including one or more transparent windows H, V and defining a housing interior region. As a target object is swiped or presented in relation to the transparent windows an image of the target object is captured. Cameras C1-C6 have an image capture sensor array with a global shutter is positioned within the housing interior region for capturing an image of a bar code within a camera field of view. All the cameras produce images in a sequential manner during an image frame time period. An image processing system has a processor for decoding a bar code carried by the target object. The processing system responds to signals from a light sensor to terminate object illumination when an adequate image exposure has transpired.

摘要： An imaging engine includes a plurality of linear imaging arrays, image formation optics, one or more illumination module and supporting circuitry that are embodied within a modular engine housing. The plurality of linear imaging arrays and image formation optics are mounted on an optical bench and provide field of views corresponding to the plurality of linear image arrays. The one illumination module produces planar light illumination that substantially overlaps the field of views corresponding to the plurality of linear imaging arrays. The imaging engine can compensate for aspect ratio distortions that result from variations in velocity of engine with respect to target object(s). The engine can adjust the optical power level and/or illumination time period for the illumination that overlaps one or more of the FOVs of the linear imaging arrays of the engine for speckle reduction/constant white levels. The engine also supports image velocity estimation, aspect ratio compensation, jitter estimation and compensation, bar code detection, OCR, and image lift operations.

摘要： A code symbol reading device includes a portable housing that contains a source of optical energy. This optical energy is projected into a scan field external to the housing and is incident upon a code symbol situated on an object located within the scan field. Optical energy reflected off the code symbol is detected within the housing to produce scan data that is indicative of the detected optical energy. The scan data is processed to detect and decode the code symbol and to produce symbol character data that are representative of the decoded code symbol. A data packet utilizing the symbol character data is constructed and then used to modulate an electromagnetic carrier sign that is transmitted to a base unit. At the base unit, the carrier signal is demodulated and the data packet is recovered. The received data packet is processed to recover the symbol character data, and an acknowledgment signal is generated to acknowledge the receipt of the symbol character data at the base unit.
