    producing binary scan spot signals representing the presence or absence of indicia elements at closely-spaced and uniformly-spaced point along each scan line;

    storing said scan spot data signals;

    processing the scan spot data signals representing one of said kinds of indicia to produce corresponding processed data signals;

    storing said processed data signals;
