Appeal No. 1997-0014
Application No. 08/192,937
The examiner’s contentions to the contrary
notwithstanding, memory storage size in image digitizer 50 is
not discussed in column 5 or in any other column of D’Aoust.
The mere fact that D’Aoust’s “entities 48, 52, 56, 60, and 64
represent a single document image pipelined processing
assembly” (column 4, lines 23 through 26; Figure 2) does not
mean that compression and other steps may take place while
image data is still being received from the document scanner.
D’Aoust is completely silent concerning the use of the
“pipeline-based system . . . to perform operations
concurrently rather than sequentially so that maximum
efficiency can be achieved.”
Appellants argue (Reply Brief, page 3) that:
None of the prior art including D’Aoust ‘104
discloses or suggests a combination of elements in
which a standard compression algorithm like the
CCITT compression algorithm is applied to
compressing non-transposed pixel data scanned from a
document using a document scanner in a multiple
processing channel environment wherein . . .
compression in each channel begins after the first
non-transposed scan line of pixels is generated but
before the last non-transposed scan line of pixels
is derived from scanning the document . . . .
We agree with appellants’ arguments. When the teachings
of D’Aoust are considered in toto, it is very clear that the
