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.

摘要： Systems and methods for successfully decoding optical images of objects of interest when such objects are situated outside a conventional working range of an imaging system, or when such objects are degraded. The systems and methods are based upon a comparison of computed signals corresponding to distorted images that would be obtained from known objects, such as barcodes, when viewed outside a working range, or when degraded, with actual signals obtained from the object of interest. The computed signals in one embodiment are recorded in a lookup table. An advantage of the systems and methods disclosed is that there results a smooth, monotonic probability of correctly decoding the image of interest, even beyond the working distance. A handheld or portable apparatus useful for practicing the invention is also disclosed.

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.
