Abstract: A method of operating a workstation includes capturing multiple monitoring images each being captured with the imaging sensor while the illumination light source is energized during one of multiple short exposure-time-periods, and detecting a checkup-condition that includes analyzing the multiple monitoring images to determine the presence of any adverse feature on workstation's window. Each of the multiple short exposure-time-periods is shorter than four times of a threshold exposure-time-period but no shorter than 25% of the threshold exposure-time-period. The threshold exposure-time-period is a minimal exposure-time-period needed for the imaging sensor to capture recognizable patterns of a barcode that is in directing contacting with the window while the illumination light source is energized.

Abstract: An imaging barcode scanner and method are provided. The scanner includes a housing defining a work surface, a window supported by the housing, a first array of photosensitive elements having a first field of view traversing the window and intersecting the work surface at a first angle, and a second array of photosensitive elements having a second field of view traversing the window and intersecting the work surface at a second angle. The scanner also includes a processor connected to the first and second arrays of photosensitive elements, and configured to: receive a first image of the work surface from the first array of photosensitive elements, and a second image of the work surface from the second array of photosensitive elements; register the first image with the second image; and generate an enhanced image of the work surface based on the registered first image and second image, the enhanced image having a greater pixel density than the first image and the second image.
