8, 25 through 29, 42, 44 and 46 remain before us on appeal.
The disclosed invention relates to a method and system
for compressing non-transposed image data derived from a
scanned document.
Claim 3 is illustrative of the claimed invention, and it
reads as follows:
3. A method of processing non-transposed image data
derived from scanning a document using a document scanner,
with the image data presented in the form of successive non-
transposed scan lines of pixels, with said scan lines of
pixels including a first non-transposed scan line of pixels
and a last non-transposed scan line of pixels to be processed
from scanning said document, said method comprising the steps
of:
(a) splitting each non-transposed scan line of pixels
into a plurality of processing channels, with a predetermined
number of pixels being located within each of said processing
channels, and with each of said processing channels having
overlap pixels assigned thereto at the time of said splitting,
with said overlap pixels being located between extremities of
said processing channels; and
(b) initiating thresholding of the pixels in said
processing channels in parallel after a predetermined number
of successive non-transposed scan lines of pixels has been
generated but before the entire document has been scanned
using the document scanner, with said thresholding using said
1Claim 5 improperly depends from canceled claim 4.
