Appeal No. 1999-2019
Application No. 08/646,810
As explained on pages 5 and 6 of the Karasawa translation, control section 6 sends
transmission parameter N to read timing control section 13, which instructs data control
section 14 of the “read timing” (T x N), which is the minimum scanning time required by the
1
scanning components times the parameter “N,” to lengthen the scan cycle if necessary
should the external equipment 16 require more time to receive the data. Note Figure 5
and compare Figure 6a (N=1) with Figure 6b (N=2); in Figure 6b the “read timing” is
effectively doubled to allow for the longer time the external apparatus requires for receiving
data from “Memory A read” and “Memory B read.”
Instant claim 45 requires, inter alia, a discriminator which discriminates “whether
transfer of an image signal from the image pickup device to the memory is in operation,”
and a controller which controls the timing “of next exposure of the image pickup device in
accordance with a result of the discriminator.” Although there inherently must be some
sensing of the image signal being written to memory 14b or 14c (Fig. 5), there is no
disclosure that this sensing, or discrimination, affects the timing for the next exposure
cycle. The timing for the next cycle is determined, in contradistinction, by the time that is to
be required for the external apparatus to receive the data to be transferred in the next
cycle. The determination occurs prior to any operations which concern the data output
buffers.
