data associated with the same document begins.” According to
the appellant (Reply Brief, page 4):
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 wherein
compression 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 same document using the document
scanner and such that reference and target rows of
pixels defined by the compression algorithm extend
in a direction which is perpendicular to the non-
transposed scan lines of pixels.
We agree with appellant’s arguments. 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 “the compression
steps may take place while further image data is being input
(i.e., ‘before said last column of binary pixels is
received’).” Although “[t]ransposer buffers 300 and 302 [in
the transposer compressor assembly 60] are substantially
always ready to accept image data associated with document 16"
(column 16, lines 29 through 31), this buffer readiness does
not translate into compression of pixel data while the image
