Appeal No. 96-2440
Application 08/099,289
appellants correctly point out that the synchronization signals
of Hunt are not added to the video data signals during Hunt’s
vertical blanking intervals. In the reply brief on page 4, the
appellants state:
Col. 6, lines 30-36 in Hunt et al. only discloses
adding synchronization signals to the image signal, but
these synchronization signals are not added and in fact
could not be added during the vertical blanking period.
The vertical blanking period is the time at which
charge which has just been stored in optically
sensitive portions of an array is shifted out of the
array to generate data representative of the image.
Only when the charge has been shifted out of the array
to form the image signal could information signals be
added to the image signal and this would be after the
vertical blanking period. Hunt et al. does not teach
or suggest anyway to add information signals into the
optically sensitive portions of the array to be
transferred during the vertical blanking period.
We agree with the appellants that in connection with Hunt,
the examiner has recognized the vertical blanking interval as
that time period during which the charges on the photosensitive
image section 22 are shifted to a storage section 24. See
examiner’s answer at page 4, lines 12-16, and page 7, lines 9-14.
The examiner nowhere explained how the synchronization signals of
Hunt can be deemed as being added to the video data signals
during the vertical blanking interval. Thus, the appellants are
correct that even under the examiner’s unreasonable
interpretation of the claim term "non-useful or dead (i.e., dark)
