Appeal No. 95-2827
Application 07/983,211
Figure 2B of Itoh shows a linear representation of pixel
density from 0 to 255 with various intermediate numerical
values associated with it. As to this Figure, column 4, lines
1 to 3 states that “since the density data is expressed by
eight bits, 0 to 255 denote the density gradation of the
pixel.” Finally, this reference states at column 5, line 65
through column 6, line 2 that “the density data of each pixel
is constituted by eight bits so that it is possible to express
the density data of the pixel by 256 (integer) density
gradations (from 0 to 255). That is, the minimum density is
the integer 0, and the maximum density is the integer 255.”
It appears that the examiner is intending to correlate
some type of distance value associated with the rather linear,
straight line-like determination of pixel density values from
0 to 255. However, as asserted by appellant, pixel density
does
not equal distance between pixels. The examiner’s view that
Itoh teaches the determination of any distance from any pixel
to another pixel because it teaches Laplacian calculations
(initially expressed in the abstract) is also misplaced.
