A device for processing image data relating to bar codes is described. In one embodiment a bar code verification device is provided having an ergonomic form factor characterized by a domed hand held trigger and a viewing window. The verification device may be disposed in a network that includes a host processor system and other bar code reading devices which may include other bar code verification devices. Processing circuitry for processing image signals corresponding to printed bar codes may be partially disposed within the hand held verification device and partially disposed within a host processor system spaced apart from and associated with the hand held verification device. The hand held verification device may be in wireless communication with the host processor system to which it is associated. The bar code verification system may include signal enhancement modules which interpolate constructed pixel values from actual pixel values and which correct for signal degradation resulting from high frequency spatial sampling.

Device and system for processing image data representing bar codes

The invention is an apparatus configured to provide self-alignment in use when measuring the print quality of an encoded indicium. The apparatus is configured to exclude ambient light, and to align an encoded indicium located at a first aperture defined in a first surface of the apparatus with an imager positioned at a second aperture defined in a second surface of the apparatus. A source of illumination is provided to illuminate the encoded indicium during an interval when the encoded indicium is undergoing a verification process. An illumination control is provided to control the source of illumination. The apparatus can be controlled using a computer and a computer program recorded on a machine-readable medium.

Device and system for verifying quality of bar codes

A hand-held instrument for reading a bar code symbol obtains print quality parameters by analyzing a signal resulting from code reading, using an internal computer having memory contained in the instrument. The instrument includes a graphic display comprising a display device such as a liquid crystal having a matrix of elements arranged in areas which provide a message containing a plurality of dot matrix characters, other areas where the elements are formed into segments for display of alphanumeric characters and still other areas where the elements are formed into legends. The computer has memory for storing fixed or variable text messages which are selectively displayed depending upon the results of the print quality analysis. The display is selectively orientable (flippable) to present messages in the message area, characters in the segment area and graphics in other areas in upright position and in proper orientation for readability by use of the controls to set the display to present the messages either in left or right-handed orientation. The instrument can be handled in either the right or left hand and the display presented in readable position. The areas are arranged so as to be mirror-wise symmetric about a longitudinal axis through the instrument so that when the computer writes data into the array of the graphic driver, it is written in an orientation and ordered so that the display presents the graphics upright and in order (left to right in the American system) for viewing.

Template for hexagonal code symbol area

A print quality, see-through template determines if a hexagonal coded symbol area imprinted on a package falls within allowable limits. The template includes boundaries corresponding to a minimum allowable coded symbol areas and boundaries corresponding to a maximum allowable coded symbol areas. When placed on top of the coded symbol area of the package, it can be determined if the encoded symbol area falls within the bounds shown on the template. The template also includes alignment hexagons for lining up to orientation hexagons that exist on hexagonal code labels. Once these hexagons are lined up, a bull's eye center on the coded symbol area is compared to a dual-size, inverse-color bull's eye on the template, to ensure that the bull's eye meets the specified requirements of the hexagonal code. The template can also be used with a magnifier to make it easier for an operator to align the alignment hexagons on the template with the orientation hexagons on the encoded symbol area, and to allow for the bull's eye pattern to be viewed at a greater size.
