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.

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.
