Appeal No. 95-2827 Application 07/983,211 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 8Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
