An optical reader having a picture taking mode and a decode mode. In a picture taking mode, the reader captures and outputs a frame of image data without attempting to decode a decodable symbol in the frame. In the decode mode, the reader captures a frame of image data and attempts to decode a decodable symbol represented in the frame. The reader may have a decode mode in which light from an aiming light source is received by an image sensor.

A method of operating an image reader includes the steps of: searching a digital image for nominally straight edges; characterizing the nominally straight edges in terms of length and/or direction; determining a predominant orientation of the nominally straight edges; establishing a group of edges as a function of their proximity to the center of the image; establishing a group of edges as a function of their proximity to other remaining edge positions; and, transmuting a rectangle bounding those edges into a rectified image; wherein a rectified image is an image that is cropped or rotated.

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.

The invention relates to an imaging device of the type having an imaging assembly including a two dimensional image sensor. In one embodiment an imaging device can be used to obtain an area image representation. In one embodiment, the image representation can be processed. The processing of the image representation can include recognition of an indicia represented in the image representation. In one embodiment an image imaging device can output image data to a first external processing system responsively to reorganization of first indicia and can output image data to a second external processing system responsively to recognition of second indicia.

The invention relates to a microprocessor-based decoder board for an optical reader having in one embodiment a plurality of imaging modules that provide frames of image data having a plurality of formats. In one method for operating the decoder board of the invention, and a multiple imaging module reader comprising the decoder board, a frame of image data captured by a selected imaging module is decoded. The decoder board determines the format of the frame of image data from information about which of the plurality of imaging modules provided the frame of image data or from information about the frame of image data, activates as necessary a command to prepare the decoder board to decode the frame of image data according to the format provided by the imaging module, and performs the decoding.
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.
