摘要： Es wird ein kamerabasierter Codeleser (10) zum Lesen eines optischen Codes (44) auf einem Objekt (40) in Relativbewegung zu dem Codeleser (10) angegeben, der einen zeilenförmigen Bildsensor (18) zum Aufnehmen einer jeweiligen Bildzeile und eine Steuer- und Auswertungseinheit (24, 25, 26) mit mindestens einer ersten Vorverarbeitungseinheit (24) und einer weiteren Verarbeitungseinheit (25) aufweist, wobei die erste Vorverarbeitungseinheit (24) mindestens mittelbar mit dem Bildsensor (18) verbunden und dafür ausgebildet ist, im Laufe der Relativbewegung Bildzeile für Bildzeile auszulesen, in einer Vorverarbeitung eine jeweilige Bildzeile mit einem Zoomfaktor z neu zu skalieren und dann an die weitere Verarbeitungseinheit (26) weiterzugeben, und wobei die weitere Verarbeitungseinheit (26) dafür ausgebildet ist, aus den Bildzeilen den optischen Code (44) zu lesen. Der Bildsensor (18) weist mehrere Zeilenanordnungen (20a-d) von Lichtempfangselementen (22) auf. Ein Teil der Lichtempfangselemente (22) ist für weißes Licht und jeweils ein anderer Teil der Lichtempfangselemente (22) für Licht jeweils nur einer Farbe empfindlich, und so sind ein Grauwertkanal zur Aufnahme von grauwertigen Bildzeilen und mehrere Farbkanäle zur Aufnahme von farbigen Bildzeilen gebildet. Die erste Verarbeitungseinheit (24) weist mehrere parallele Verarbeitungskanäle (50) auf, mindestens einen Verarbeitungskanal (50) für den Grauwertkanal und mindestens einen Verarbeitungskanal (50) je Farbkanal, um jeweils eine grauwertige Bildzeile und zugehörige farbige Bildzeilen parallel und synchron neu zu skalieren.

摘要： A display device, suitable for collecting fares for example by reading tickets has integrated barcode scanning. It comprises a display 160 configured to display dynamic messages, a first glass layer 110 displaced from the display, a transreflective glass layer 130 positioned between the first glass layer and display. It also has a scanner 140 positioned so that it emits light rays 170 reflected by the transflective glass layer through the first layer and detects light rays reflected by the transflective glass layer from the first glass layer, as well as a processor capable of decoding a scanned barcode to determine a proper fare. There may be a reflector 120 angled from the first glass layer capable of reflecting light from the scanner to the transflective glass layer. The first layer may have one or more portions for mobile device placement and may also have one or more portions for printed barcode placement. The device may also have a radio frequency identification (RFID) reader 150 along with having a portion of the first glass layer allocated for smartcard placement.

摘要： Systems and methods of operation for a machine-readable symbol reader for estimating the distance of a scanned target object or item labeled with indicia, such as a machine-readable symbol. The reader may include an illumination subsystem which projects a light pattern (e.g., line) out from the reader. The reader may capture an image of the target object while the light pattern is projected thereon and analyze at least one detectable characteristic of the pattern to estimate distance of the target object relative to the reader. A one-dimensional sensor array of the reader may be exploited in part for imaging a symbol and in part for imaging detectable characteristics (e.g., edges) of the projected illumination pattern which allows for estimation of the reading distance. A central portion of the one-dimensional sensor array may be dedicated to imaging a machine-readable symbol and lateral portions may be dedicated to implementing a range finder.

摘要： The present invention is directed to systems and methods for configuring network devices that include native scanning or image-reading elements. Network configuration information is provided in a scannable image. A network device reads the scannable image and extracts configuration data from the image. The device then uses the extracted configuration data to configure the device to operate on a desired network.

摘要： The invention provides a block decoding method and system for a two-dimensional code. The block decoding method includes: storing a received two-dimensional code image in an image data backup register; binarizing the received two-dimensional code image based on a gray-scale value of a pixel; searching for a boundary line of the two-dimensional code image based on a position detection pattern; searching for a version number and a correction pattern of the two-dimensional code image; segmenting the two-dimensional code image into regions based on the boundary line of the two-dimensional code image, a straight line where a boundary line of the position detection pattern is located and a straight line where a boundary line of the correction pattern is located; calculating the number of bits in each of the regions based on the position detection pattern, the correction pattern and the version number; segmenting each of the regions into bit regions each of which corresponds to one bit data, based on deformation amount of the position detection pattern and deformation amount of the correction pattern; re-acquiring the received two-dimensional code image stored in the image data backup register; calculating an average gray-scale value of all the pixels in the bit region as a gray-scale value of the bit region; calculating a gray-scale threshold of each of the bit regions based on the gray-scale value of the bit region using the Otsu method; binarizing the bit region based on the gray-scale threshold so as to obtain a binarized two-dimensional code image; and decoding the binarized two-dimensional code image. In the system, the two-dimensional code image is segmented precisely, thereby effecting quick and accurate decoding.
