Appeal No. 98-1396
Application 08/300,666
flexible, variable scaler means for storing a number of different selectible
[sic] scaling algorithms; scaler-output means; and input means for receiving
scanned lines of pixel data and feeding it sequentially line-by-line, pixel-by-pixel to
said scaler means; and input means also including "scale factors" for selecting a
said algorithm; said scaler means including mapping means for executing a two-
dimensional mapping of adjacent pixel values and adjacent scan line values; said
arrangement also including command store means for storing said scaling
algorithms with a command register input for said scale factors;
wherein said scaler means also includes a First ROM R-1 input by said input
means for storing pixel values at prescribed addresses; a Second ROM R-2 for
similarly storing previous pixel values, being input in parallel with First ROM R- 1;
Latch means to which said ROMs are output; and pixel Count means reset with
each new scan line;
wherein a "current pixel" value is input to a prescribed address in said First
ROM, along with a "pixel count" number from said Count means, and an associated
scale factor; and
wherein Adder means is interposed between said ROMs and said Latch
means to execute addition mapping.
The prior art references of record relied upon by the Examiner in rejecting the
appealed claims are:
Ohuchi 4,907,284 Mar. 06, 1990
Hackett et al. 5,140,648 Aug. 18, 1992
Claims 2, 7-10, 14, 15, 17, and 23-29 stand rejected under 35 U.S.C. § 103 as
being unpatentable over Ohuchi in view of Hackett.
Claims 7-10 stand rejected under 35 U.S.C. § 112 first paragraph, as being based
upon a lack of written description.
