ABSTRACT:
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.
