摘要： This relates to a system for sensing the presence of an object in the field of view of an imaging assembly of a stationary position optical reader. The system includes a light source disposed in a field of view of the imaging assembly, which is configured to emit light in the direction of the imaging assembly according to a predetermined light pattern. A determination as to whether an object is present in a presentation area of the reader system is made by detecting for the presence of the light pattern in image information generated by the imaging assembly.

摘要： The invention relates to a system for imaging a scene comprising an optical reader and a specially structured symbol configured complementarily with the reader so that when the reader reads the symbol, the reader reads image data in an image data reading region. The image reading instruction symbol of the system may include indicators for controlling various aspects of the image reading process such as the dimension of the image capture region, the relative position of the image reading region. If the image reading instruction symbol is of a type whose actual size, orientation, and distortion can be determined, scaling, orientation, and distortion characteristics determined from the image reading instruction symbol can be used to improve the image reading process. A feedback feature may be included in the reader for indicating to a user whether the reader should be moved in order to improve image reading.

摘要： The invention is a method for omnidirectional recognition of recognizable characters in a captured two-dimensional image. An optical reader configured in accordance with the invention searches for pixel groupings in a starburst pattern, and subjects located pixel groupings to a preliminary edge crawling process which records the pixel position of the grouping's edge and records the count of edge pixels. If two similar-sized pixel groupings are located that are of sizes sufficient to potentially represent recognizable characters, then the reader launches “alignment rails” at pixel positions substantially parallel to a centerline connecting the center points of the two similarly sized groupings. A reader according to the invention searches for additional recognizable characters within the rail area, and subjects each located pixel grouping within the rail area to a shape-characterizing edge crawling process for developing data that characterizes the shape of a pixel grouping's edge. After adjusting the orientation representation of the shape-characterizing data the reader compares the developed shape-characterizing data to previously stored shape-characterizing data to determine the character represented by the grouping on the basis of the best fit data.

摘要： An optically readable two dimensional symbology employed to encode a string of characters belonging to a source string alphabet. The two dimensional symbol can comprise an ordered plurality of printable elements. The printable elements can be arranged in a rectangular array. The printable elements can be positioned on a grid diagonal to the longitudinal axis of the rectangular array, and sequenced according to a pre-defined pattern. Each character of the character string can be encoded into a sequence of printable elements using an encoding scheme comprising at least one code set. A code set can include a plurality of bit sequences. Each bit sequence can correspond to a group of one or more characters of the source string alphabet. Each bit sequence can comprise one or more binary digits. The first binary digit can be encoded by a printable element printed in a printable element position, and a second binary digit can be encoded by a vacant printable element position.

摘要： A TTR time of a reading apparatus can also be reduced by designing an apparatus to exhibit a certain timing relationship between a receipt of a trigger signal and/or more of image capture and decoding. An apparatus in one embodiment can be configured to continuously capture frames of image data prior to receipt of a trigger signal and can further be configured so that an output decoded message is decoded from a frame of image data having a capture initiation time of prior to the time of receipt of a trigger signal. An apparatus configured to output a decoded message from a frame of image data having a capture initiation time of prior to a time of receipt of a trigger signal can have a TTR time of less than a frame capture period of the apparatus.
