20130181055 | DECODING BARCODES DISPLAYED ON CELL PHONE - A method of decoding a barcode includes generating a first illumination towards a target object with a first illumination level, capturing a first image during a first exposure time period, and determining a first location and a second location on a scan line in the first image to find a switchover condition. If the switchover condition indicates the presence of a mobile display device, the method further includes generating a second illumination towards the target object with a second illumination level, capturing a second image during a second exposure time period, and decoding the barcode in the second image. Here, at least one of the second illumination level and the second exposure time period is determined based on values of pixels on the scan line between the first location and the second location. | 07-18-2013 |

20140048684 | HIGH PERFORMANCE SCAN ENGINE WITH REAR-FACING IMAGE SENSOR IN HANDHELD ARRANGEMENT FOR, AND METHOD OF, IMAGING TARGETS USING THE SCAN ENGINE - An arrangement for, and a method of, electro-optically reading a target by image capture, employ a scan engine in a handheld housing having a tilted handle. A single tilted printed circuit board (PCB) in the handle has front and rear surfaces that respectively face toward and away from the target during reading. An optical assembly having a pair of fold mirrors is mounted on the rear surface, for receiving return light from the target through an aperture in the PCB along the horizontal, and for directing the return light along a folded path. An imaging lens assembly projects the return light onto a solid-state, two-dimensional, image sensor to enable the return light to be detected over a field of view, and to generate an electrical signal indicative of the detected return light. | 02-20-2014 |

20150048165 | APPARATUS FOR AND METHOD OF MINIMIZING SPECULAR REFLECTIONS IN IMAGING FIELD OF VIEW OF WORKSTATION THAT READS TARGETS BY IMAGE CAPTURE - A workstation electro-optically reads targets by image capture, and includes a housing, a generally planar window, an imaging module, and a generally planar fold mirror between the window and the module. The module has an illuminating light assembly for directing illumination light along an illumination path through the window at a target for return therefrom during reading, and an image sensing assembly for detecting return illumination light through the window along an imaging path over an imaging field of view during reading. The fold mirror folds the illumination and the imaging paths. The fold mirror and the window lie in planes that are substantially parallel to each other to prevent reflections of the illumination light off of the fold mirror and the window from entering the imaging field of view as virtual images that degrade target detection by the image sensing assembly. | 02-19-2015 |
