These calculations are performed on an object pixel and on
peripheral pixels around the object pixel to obtain corrected
data. This calculation is performed in such a manner that a
difference in density between the object pixel and each of the
peripheral pixels is calculated and all the differences are
summed. Figure 4 of Itoh shows (and each succeeding
embodiment having a corresponding figure shows) that object
pixel Dm,n in memory 11 is surrounded by other pixels in its
periphery, which are respectively operated upon to determine
the Laplacian calculations just mentioned. These calculations
in no way
relate to determinations of distances between the pixels
depicted but rather operate upon the actual density data value
associated with each pixel per se. Thus, the examiner’s
reliance upon Itoh to teach or otherwise suggest to the
artisan some kind of a distance determination between pixels
in any manner is misplaced.
Similarly, at pages 3 and 4 of the answer, the examiner’s
responsive arguments switch to relying upon Eschbach’s
teaching at column 7, lines 65 to column 8, line 10 as a basis
