Appeal No. 2000-0979
Application 08/767,743
The original video signal and the scaling signal coexist. The
scaling signal does not change or affect the original video
signal.
It is the examiner’s position that Inoue’s automatic
exposure/white balance (AE/AWB) arithmetic circuit 42, along
with elements 25-30 provide a means for inserting a scaling
signal into the video signal. (Answer at 4). The examiner
states the following:
[E]lement 42 of Inoue et al, by calculating exposure
control values, the gain of the amplifier 25 and the
white balance correction value used during the
reproduction based on the exposure data, provides the
same scaling signal that is inserted into a video signal
as claimed (see Figure 1, and columns 13-15 and 17 of
Inoue et al). (Answer at 7).
The examiner has failed to demonstrate that elements 42
and 25-30 of Inoue insert a scaling signal into the video
signal as claimed. Inoue describes the AE/AWB arithmetic
circuit 42 as controlling iris driver 40 and CCD driver 41,
and sending gain AG and WB correction values to amplifier 25
and WB circuit 26 to set the gains of the amplifier 25 and the
WB circuit 26. (Inoue, column 18, lines 4-12).
The signals coming from the AE/AWB arithmetic circuit 42
control the gains and drivers of other circuits. Controlling
