  • receiving a user-initiated start signal;

    in response to said user-initiated start signal, determining if the distance between said imager and said surface is within a predetermined range of distances, said predetermined range of distances corresponding to the operating range of the imager;

    in response to said surface not being within said predetermined range of distances, again determining if the distance between said imager and said surface is within said predetermined range of distances; and

    in response to said surface being within said predetermined range of distances, performing the steps of;

    determining a proper shutter speed for said imager;

    obtaining an image of said information indicia using said proper shutter speed, thereby providing image data; and

    providing output data corresponding to said image data.
