    摘要: A code reader comprises a first imager and a second imager configured to capture an image with different field of views, a first illuminator and a second illuminator configured to project a different illumination pattern, and a processor operably coupled to the imagers and the illuminators. The processor configured to activate the first imager and the first illuminator as a receiver pair responsive to detecting a first condition, activate the second imager and the second illuminator as a receiver pair responsive to detecting a second condition, and decode an optical code using an image captured by the selected receiver pair.

    摘要: An optical scanner captures a plurality of images from a plurality of image-capture devices. In response to the activation signal, an evaluation phase is executed, and in response to the evaluation phase, an acquisition phase is executed. In the evaluation phase, a first set of images is captured and processed to produce a virtual frame comprising a plurality of regions, with each region containing a reduced-data image frame that is based on a corresponding one of the plurality of images. Also in the evaluation phase, attributes of each of the plurality regions of the virtual frame are assessed according to first predefined criteria, and operational parameters for the acquisition phase are set based on a result of the assessment. In the acquisition phase, a second set of at least one image is captured via at least one of the plurality of image-capture devices according to the set of operational parameters.

    摘要: A reader contains a housing with a window having a peripheral rim. The housing has a device for reading coded information which generates a field projecting through the window towards the outside of the housing, and has a device for visually indicating the result to a user. The visual indication device generates an indication appearing substantially at least on the window, on a portion of the peripheral rim of the window, or on a portion of the housing adjoining laterally the peripheral rim of the window. The housing portion is at least on the left side, right side, or below the window. Additionally, a camera based checkout security system includes at least a checkout security camera and a fixed position reader of coded information. The checkout security camera generates a camera field of view directed towards the window of the fixed position reader of coded information.

    摘要: An imager module for an optical code reader may include a camera comprising a lens system, and an actuator for moving the lens system operatively connected to the lens system for autofocus adjustment. The actuator for moving the lens system comprises a linear electric motor with a drive shaft, a position sensor device adapted to detect the position of the drive shaft within a predefined stroke length and a control device adapted to control the movement of the drive shaft. The control device and the position sensor device are integrated in a single PCB, the electric motor comprises a frame that supports the drive shaft, and the single PCB constitutes part of said frame. On optical code reader may include such an imager module.
