Appeal No. 1998-1395
Application No. 08/606,634
With respect to the section 102 rejection of claims 22 and 28 over Hiratsuka,
appellants argue that there is no anticipation because "[t]he claims as now presented
include the feature of using grey level values of the original pixels and distances between
the original pixels to determine the grey level values of the new pixels." (Brief at 5.)
The Answer's statement of the rejection does not point out where Hiratsuka
discloses the feature of using distances between original pixels in the determination of
grey level values for the new pixels. In the Answer's response to appellants' arguments, the
examiner indicates that Hirasuka "inherently" uses distances between pixels in performing
interpolation, and refers to Fig. 12 and column 9, lines 41 through 63 of the reference. The
examiner further refers to a "ratio of distances" between pixels as shown in Figs. 12a and
12b.
Appellants respond (Reply Brief at 7) that column 9, lines 41 through 63 of
Hiratsuka is not descriptive of the reference's Figure 12, and allege there is no use of
"distance" in interpolation. Appellants further argue (id. at 6-7) that the operation
represented by Figure 12 does not make use of distances between original pixels.
Hiratsuka describes Figure 12 at column 8, line 60 through column 9, line 13.
Dither matrix 2-c is applied to enlarged halftone image 12-a, yielding enlarged, binary
coded dither image 12-e. Dither matrix 12-d is applied to reduced halftone image 12-b,
yielding enlarged, binary coded dither image 12-f.
