Appeal No. 2003-0350
Application 08/771,399
motivation for the Examiner’s proposed combination of references
has not been set forth.
After reviewing the arguments of record from both Appellants
and the Examiner, we are in general agreement with Appellants’
position as stated in the Briefs. In particular, we agree with
Appellants that none of the Parulski, Ozaki, and Nishimura
references is concerned with the problems associated with noise
created by differences in gain among output amplifiers. In this
regard, our interpretation of the disclosure of Nishimura
coincides with that of Appellants, i.e., while Nishimura
discloses the setting of amplification factors of amplifiers 71-
74 associated with color sensing elements to counteract aliasing,
there is no disclosure of any concern with noise frequency
problems caused by the differences in gains among the amplifiers.
Further, while the Juen reference does indeed address
problems associated with the disparity of gains in amplifier
output channels of an image processing system, Juen’s solution is
to generate offsetting voltages, not to filter out the noise
frequencies caused by the amplifier gain mismatch. Given the
disparity of problems addressed by the applied prior art
references, and the differing solutions proposed by them, it is
our view that any attempt to combine them in the manner proposed
