摘要： A two-dimensional matrix code, method of producing the code and a method and device for reading the code are presented. The code is a round, compact and distinct code that stores an error-corrected 64-bit number, embedded targets, and quality control information within a space small enough for imaging using a compact, hand-held code finder. The code incorporates white space both between the data areas and targets for easy identification of the code and to aid in image processing, and within the data area to correct for errors that sometimes occur when printing using low-quality techniques. Additionally, the code includes features to correct for other printing errors, such as variations in printing press speed and intentional aspect ratio stretching to fill copy space. The code is thus robust enough to be incorporated within newsprint and is also easily imaged using specially constructed code finders. A code finder device and a method of using the finder for acquiring a code of the present invention is also presented. The finder is portable and easy to use, requiring no rotational orientation for correct acquisition. Several embodiments are described, in which the finder contains illumination and communications electronics and means to notify the user of correct operation of the finder.

摘要： An improved card scanner for imaging and decoding indica such as bar codes on a side surface of an inserted card. The device is electrically powered and features a double scanning method using an electronic imaging element and processor which turns off unnecessary power when not required. This is accomplished through the use of a processor and software to determine if a complete image of the bar code on the inserted card has been captured and allowing immediate removal of the card. Should the image of the bar code be incomplete, a second scan is conducted of the bar code as it is removed and a complete image formed from the two individual scans. The device can also be used to compare photographs scanned from a card with the digital photograph scanned from a two dimensional bar code and to display both photos for viewing.

摘要： A method and apparatus for aligning a scan pattern to a two dimensional bar code having parallel rows of codewords. The two dimensional bar code is scanned with a scanning pattern oriented such that a plurality of lines thereof cross the bar code rows. A determination if there is a non-zero angle between at least one of the plurality of lines and the rows by decoding codewords in rows intersected by the at least one line is made and the orientation of the scanning pattern is adjusted to reduce the absolute value of the angle.

摘要： An image processing system has a host computer to which a scanner and a printer are connected. A color space conversion module, for converting a color space of a device input-output image into a predetermined color space, likewise a resolution conversion module, for converting the resolution of the image into a predetermined resolution, and a counterfeit determination module, which determines a degree of a match between the image signal converted into predetermined color space and resolution and a particular image, are included in the OS of the host computer. The OS further includes an anti-counterfeiting module for preventing or suppressing counterfeiting based on the results of the matching determination. By providing the various modules in the OS instead of the device, the system is able to provide counterfeiting prevention and anti-counterfeiting capabilities designed to accommodate a plurality of different types of input-out devices efficiently.

摘要： A barcode with enhanced visual quality may be used with an item such as a document. The barcode includes a background field having an embedded graphic. The background caries data related to the item. The embedded graphic may obscure some background data. A bar coding apparatus, system and a corresponding method involve two basic functions: encoding and decoding. The encoding function uses an encoding algorithm to generate the barcode. The graphic is then embedded onto the barcode and the thus-generated enhanced visually significant barcode is placed on the item. Decoding involves machine-reading the barcode using a decoding algorithm. The decoding algorithm can operate with or without an original bit map that was used to generate the graphic. The graphic may be enhanced in a manner that may make at least a portion of the encoded information within the graphic readable by a human.

A reading method of this bar code includes a process for correcting the distortion of the image of the two-dimensional bar code obtained from the area sensor by the projection transform, a process for correcting bright spots appearing in the image, and a process for decoding the two-dimensional bar code based on the image data of the two-dimensional bar code corrected by the two processes. This invention enables size-reduction of the reading device of the two-dimensional bar code and also achieves a higher reading speed of the reading device.

摘要： To facilitate the decoding of a 2D symbol (e.g., PDF417), a plurality of positioning lines are attached to the 2D symbol. Depending on implementation, these substantially parallel positioning lines may be provided on at least one side of the symbol or superimposed on the symbol. A scanning device is provided to capture an image of the symbol together with these positioning lines that are then detected to determine an orientation of the 2D symbol. In some cases, these positioning lines are used to correct images with distortion.
