| 20100078481 | Imaging reader and method with enhanced aiming pattern detection - An image capture system for, and a method of, reading an optical code during a reading mode, comprise an aiming assembly including a laser for emitting a laser beam having a variable intensity, and for generating an aiming pattern from the laser beam during an aiming mode prior to the reading mode, and an imager for detecting and capturing an image of the aiming pattern and the code over a field of view by exposure over an exposure time period during the aiming mode, and for detecting and capturing an image of the code over the field of view during the reading mode. A controller is operative for controlling the intensity of the laser beam during the aiming mode by increasing the intensity of the laser beam during the exposure time period to enhance detection and capture of the aiming pattern by the imager, and by decreasing the intensity of the laser beam frame outside the exposure time period for user safety. | 04-01-2010 |
| 20110089240 | IMAGING READER WITH ASYMMETRICAL MAGNIFICATION - A solid-state imager is mounted in a reader, such as a bi-optical, dual window, point-of-transaction workstation, for capturing light along an optical axis over a field of view from coded indicia. An optical assembly including non-rotationally symmetrical optics is operative for optically modifying and asymmetrically magnifying an image of the indicia and the field of view of the imager along mutually orthogonal directions generally perpendicular to the optical axis, and for increasing resolution of the imager along one of the directions. Preferably, the non-rotationally symmetrical optics includes a cylindrical lens having an aspherical profile along the one direction, and a planar profile along the other of the directions. | 04-21-2011 |
| 20110127333 | MULTIPLE CAMERA IMAGING-BASED BAR CODE READER WITH OPTIMIZED IMAGING FIELD - A multicamera imaging-based bar code reader wherein for least one camera assembly of the reader, a sensor array of the camera assembly is non-orthogonal with respect to an optical axis of an imaging lens assembly of the camera assembly such that an imaging or scanning volume of the camera assembly more closely conforms to a desired imaging field or region of the reader. In one exemplary embodiment the reader features: a housing supporting first and second transparent presentation windows and defining an interior region; an imaging system including a plurality of camera assemblies within the interior region, at least one camera assembly includes a sensor array and an imaging lens assembly, the sensor array being positioned with respect to the imaging lens assembly at an angle so as to be non-orthogonal with respect to an optical axis of the imaging lens assembly of the camera assembly. | 06-02-2011 |
