Abstract: A method of operating an image reader typically includes: 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. The rectified image is typically an image that is cropped or rotated.

Abstract: 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.

Abstract: There is described a device having a two dimensional imager. The device having a two dimensional image sensor can be a hand held device. Imaging optics can be provided for focusing light reflected from a target onto the two dimensional imager. An image including imaging data can be obtained utilizing the hand held device.

Abstract: The invention relates to decoding utilizing image data. The image data can be received from a source. A processor can process the image data for decoding. Processing for decoding can be responsive to determined information. The format of a frame of image data may be recognized. The recognizing may include determining the source of the frame of image data. The recognizing may include determining a parameter associated with the frame of image data.
