Appeal No. 1998-0740
Application 08/627,838
speed transfer decoded signal 84a. The decoded signals are
applied to decoder 85 to produce CCD drive signals E1-E4.
According to the examiner, Fig. 7 of Nagai shows that, like
appellant’s accordion clock signal, signals E1-E4 have a constant
number of transitions for a given period of time and have variable
periods for at least some of the transitions.
As to appellant’s second argument, the examiner avers that
control circuit 42 in Nakajima does alter exposure time in
response to image data. Referring to Fig. 4, the position is
taken that image data from device 31 is detected by detection
device 35, compared to the reference voltage in amplifier 36,
converted by A/D converter 41, and is supplied as shutter
controlling voltage data to the controlling circuit 42.
Lastly, as to appellant’s third argument, the examiner
contends that “In this case, One [sic] of ordinary skill in the
art would include [sic: the] clock signal driving circuit of
Nagai, in the clock signal controlling shutter speed, shutter
speed control 18 of Nakajima, to provide [sic: an] improved high
speed video camera”. Opinion
