Appeal No. 1998-0220
Application No. 08/297,437
BACKGROUND
The invention is directed to two-dimensional digital filters. Claim 1 is reproduced
below.
1. An image processing device for filtering digital image data, comprising:
a plurality of discrete one-dimensional first dimension filters operating concurrently
on real-time digital image data in a first dimension, each of the filters operating on the
digital image data in accordance with predetermined filter coefficients to produce a one-
dimensional output signal;
a single second dimension filter, operating in a second, distinct dimension, for
receiving output signals from one of the plurality of first dimension filters and operating on
the output signals in real-time in accordance with one of a plurality of sets of
predetermined filter coefficients to produce a second filtered output signal therefrom; and
means, operating in conjunction with the first and second dimension filters, for
controlling the non-predetermined selection of the first dimension filter and the set of filter
coefficients to be used as inputs to the second dimension filter.
The examiner relies on the following evidence:
Thompson et al. (Thompson) 4,766,561 Aug. 23, 1988
Kobayashi et al. (Kobayashi) 5,131,059 Jul. 14, 1992
Appellants’ Admitted Prior Art (the APA)
Claims 1, 2, 8-11, 17, 18, 24, 30, and 31 stand rejected under 35 U.S.C. § 103 as
being unpatentable over the APA and Thompson.
Claims 33 and 34 stand rejected under 35 U.S.C. § 103 as being unpatentable
over the APA, Thompson, and Kobayashi.
