Appeal No. 1997-4047 Page 4
Application No. 08/309,508
Claim 1, which is representative for our purposes,
follows:
1. An apparatus for converting color signals
comprising:
means for converting color signals in a first
color space into corresponding color signals in a
second color space,
means for reconverting converted color signals
in said second color space into corresponding color
signals in said first color space, and
means for compensating at least one of said
converted color signals in said second color space
in order to confine each component of reconverted
color signals in said first color space in a dynamic
range allowable for said component.
Besides the appellant’s admitted prior art (AAPA), the
references relied on in rejecting the claims follow:
Walowit 4,941,038 Jul. 10, 1990
McColl et al. (McColl) “Compression of colour image date using
histogram analysis and clustering techniques”, Electronics &
Communication Engineering Journal, March/April 1989, pp. 93-
100.
Claim 1 stands rejected under 35 U.S.C. § 103 as obvious
over McColl in view of Walowit. Claims 2 and 3 stand rejected
under § 103 as obvious over AAPA in view of Walowit. Rather
