A solid-state imager is mounted at a point-of-transaction workstation for capturing images of one- and two-dimensional indicia and is operated at high speed to resist image blurring due to relative movement between the target and the imager. Dedicated hardware assistance and computation resources are allocated to decode multiple, continuous and simultaneous video streams from multiple imagers at the workstation.

An imaging optical code reader is adapted for use in producing video displays and for use in motion detection surveillance using video compression and narrow band width communication links. An optical system including a plane parallel plate may be employed to change the system focal distance.

Optical code reader for producing video displays

A system and method for reading an optical code is provided. The optical code reader system includes a dual aim/illumination assembly including a single light source generating: a) light having a first intensity for providing an aim pattern visible to a user for aiming the aim pattern at a target during an aim period of a scan cycle having at least an aim period and an exposure period; and b) light having a second intensity greater than the first intensity for providing illumination during the exposure period of the scan cycle. An imager module having an array of photo sensors senses incident light and generating image signals corresponding to the sensing during the exposure period.

Optical code reader system and method for control of illumination for aiming and exposure

A system and method for performing a read operation including acquiring a series of frames of image data; processing a first frame of image data including an array of pixel data acquired while an aiming pattern was generated for determining a location L of at least one pixel of the array of pixel data that corresponds to the aiming pattern; and processing a second frame of image data acquired while the aiming pattern was not generated. The processing of the second frame of image data includes the steps of selecting at least one optical code acquired in the second frame of image data that is located at a respective location; wherein the respective location meets a predetermined condition relative to the determined location L; and providing the selected at least one optical code for further processing in accordance with the read operation.

A bar code scanning system and method for reading and processing bar code symbology uses a scanning station installed above the check-out stand and a receiving station at some distance away from the scanning station. The scanning station projects light onto a surface of the check-out stand. The projected light can have a well defined border indicating where a user should place items to be scanned. Alternatively, a pattern coincident with the projected light can be projected onto the surface and which includes a target indicating where items should be placed for scanning. Light reflected by items in the target region is processed to decode optical symbology on the item and produce a signal that is representative of said sensed symbology. Information about the scanned item can be processed and displayed by the receiving station for use in, e.g., a point-of-sale transaction. The system can also be configured to capture images of a user's payment card for use in payment processing and to store images of at least selected scanned items for use in subsequent processes.

Methods and apparatus for swipe image scanning comprising a scan stand and an imaging scanner. An exemplary scan stand comprises an illumination module and a receiving structure to receive the imaging scanner. Other embodiments further comprise a scan module, an illumination module, a processing unit, a detection component and memory. In an embodiment, the scan stand illuminates target dataforms brighter than the illumination from the scanner allowing for shorter exposure times and improved scanner performance.
