Abstract:
A method of imaging a target object with an imaging reader. The method includes the following: (1) detecting light from the target object through a lens arrangement with an image sensor to generate light-field data; (2) generating a stream of image data including image data representing an expected in focus image of the target object, and (3) processing the expected in focus image of the target object to decode a barcode on the target object. The image sensor includes an array of photosensitive elements and an array of microlenses that overlays the array of photosensitive elements located at a focus plane of the microlens.
Abstract:
Method and apparatus of detecting orientation of document using a barcode decoding. The method includes (1) capturing an image of the document with an imaging arrangement having a solid-state imager; (2) determining a presence of a barcode in the captured image of the document; (3) decoding the barcode; (4) determining an up-direction of the document as a function of an orientation of the barcode in the document; and (5) setting an orientation of the document in the captured image based upon the up-direction of the document. In one implementation, the barcode is configured with orientation data indicating the up-direction of the document.
Abstract:
An optical scanner such as a bar code scanner includes a segmented fold mirror, the individual sections of which have different profiles. By directing the scanning laser beam across the fold mirror, plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.
Abstract:
An imaging system comprises a module, focusing lens and an aperture sized to allow a target, such as a bar code, to be imaged without being illuminated by light sources on the module. The system further comprises an array of rows of pixels, the pixels in each row being spaced apart and the pixels in successive rows being offset from one another by one-half of a pixel. The array 510 may also lie in an imaging plane that lies at an angle other than a right angle with respect to an optical axis of the focusing lens. There may also be a dark room 250 in the module for enclosing the image sensor.
Abstract:
The disclosed techniques for reading postal code are adapted for processing data from an optical imager and identifying and decoding various types of postal code found in such data. A baseline is employed.
Abstract:
An imaging engine and signal processing devices and methods are disclosed for reading various kinds of optical codes. The compact structure may include a two dimensional image sensor, apparatus for focusing images at different focal disclosures, an aiming system, a hi-low beam illumination system and related signal processing circuits.
Abstract:
An optical scanner such as a bar code scanner includes a segmented mirror (14), the individual sections of which have different profiles (16,18,20). By directing the scanning laser beam across the mirror, a plurality of scan lines are created, at different distances from the scanner. This provides increased flexibility by extending the scanner's working range. In alternative embodiments, a collector mirror and/or a scanning mirror may be segmented. In addition, beam shaping may be provided by reflecting the beam from one or more aplanar surfaces.

Abstract:
A data capture device is described. The data capture device includes an imager simultaneously capturing a barcode and an image associated with the barcode. A memory is coupled to the imager for storing the barcode and the image. A processor is coupled to the memory for decoding the barcode and processing the image. A notification system notifies a user that the image is being processed prior to the processor completing the processing of the image.
