    摘要： The imager and controller of an information apparatus images the back face of another information apparatus to acquire the manufacturing number of the other information apparatus corresponding to the two-dimensional bar code provided on the back face of the other information apparatus and acquire visible light information corresponding to blinking of light emitted by the light emitter arranged on the back face of the other information apparatus. Furthermore, the controller controls the imager so as to be able to image the two-dimensional bar code and the light emitted by the light emitter.

    摘要： A 2D color barcode layout is disclosed. The barcode includes a 2D array of data cells, four corner locators, and border reference cells forming four borders between the corner locators that substantially surround the array of data cells. Each data cell and border reference cell has one of four primary colors (e.g. CMYK). Most border reference cells have the same size as the data cells, except for yellow ones which are longer. The border reference cells form a repeating color sequence along the borders, and are used during decoding to calculate (1) the channel offset (a spatial offset) of each primary color at different locations along the borders and (2) the reference (average) color values of each primary color. During decoding, the color values of each data cell is measured while taking into account channel offset which is calculated by interpolating the channel offset of the border reference cells.

    摘要： A method and an apparatus for encoding data as a two-dimensional array of pixels, as well as a method and an apparatus for decoding such data are described. Data bits for encoding are received via an input. An encoder determines blocks of pixels corresponding to the received data bits from an alphabet of allowed blocks of pixels. Each allowed block of pixels represents two or more data bits. Values of the pixels within each block of pixels in said alphabet are selected from three or more allowed values and increase continuously from a lowest value of a first pixel to a highest value of a last pixel when considering the pixels along a spiral or represent a plane having an orientation and an inclination. The blocks of pixels determined for the data bits are combined into a two-dimensional array of pixels. For decoding a pixel analyzer determines properties of pixel values of each retrieved block of pixels. A property analyzer then determines data bits for each retrieved block of pixels from the determined properties.

    摘要： A hand-supportable digital image capture and processing system supporting a multi-tier modular software, and plug-in extendable, architecture. The digital image capture and processing system can be realized as an image-capturing cell phone, a digital camera, a video camera, mobile computing terminal and portable data terminal (PDT), provided with suitable hardware platform, communication protocols and user interfaces. A third-party customer can write and install a software plug-in into the application layer so as to enhance or modify the behavior of the hand-supportable digital image capture and processing system without any required knowledge of the hardware platform, communication protocols and/or user interfaces.

    摘要： A retroreflective element, for example a retroreflector or a retroreflective film, includes a regular arrangement of multiple reflective triples, each having three side surfaces that form an angle between 88° and 92°, preferably between 89° 50′ and 90° 10′ relative to one another, and particularly preferably stand perpendicularly on one another. At least one selected triple in the arrangement has a security element having at least one diffractive structure on at least one first side surface. A modulation depth of the security element is selected in such a manner that the security element cannot be perceived when the retroreflective element is illuminated at an illumination angle

    摘要： An optically readable marker comprises a dash and two dots arranged in a pattern to allow detection of the marker, wherein the dash and dots are collinear, and wherein the dots are of the same size and shape and adjacent to each other. Multiple such optically readable markers may be combined into a composite marker, optionally with one element (i.e. a dash or a dot of the marker) being at least partially shared between two or more markers.
