Appeal No. 96-0650
Application No. 08/117,591
The disclosed invention relates to a color copier that
processes marker data during a single pass scan of a document.
The color copier also performs a thinning operation on the
marker data during the single pass scan.
Claim 36 is illustrative of the claimed invention, and it
reads as follows:
36. A copier for thinning buffered marker data during a
single pass scanning of a document, comprising:
first analyzing means for analyzing, during the single
pass scanning of the document, buffered marker data associated
with pixels adjacent to a first pixel, the first pixel being a
pixel in a first scanline, the first scanline having been
scanned prior in time to a scanline being presently scanned in
the single pass scanning of the document, to determine a
connectivity relationship of a marker line, the connectivity
relationship being between the first pixel and pixels adjacent
the first pixel; and
thinning means for eliminating, during the single pass
scanning of the document, buffered marker data associated with
the first pixel when said first analyzing means determines
that elimination of the buffered marker data associated with
the first pixel maintains connectivity of the marker line.
