Appeal No. 2001-0924
Application No. 08/885,415
Representative claim 1 is reproduced below:
1. An image compression apparatus comprising:
a first look-up table configured to provide a
quantized code upon being indexed by a single address;
a second look-up table configured to provide the
length of said code upon being indexed by said single
address; and
a predictive coding circuit coupled to said first
look-up table and to said second look-up table, said
predictive coding circuit generating said single
address;
a difference circuit, said difference circuit
configured to generate said single address by
difference said input pixel value and a predicted pixel
value; and
a third look-up table coupled to said difference
circuit, said third look-up indexed by said single
address to provide an inverse quantized code to said
predictive coding circuit.
The following references are relied on by the examiner:
Gonzales et al. (Gonzales) 4,725,885 Feb. 16, 1988
Barrett 5,341,442 Aug. 23, 1994
Claims 1, 2, 5, 6 and 9 through 13 stand rejected under
35 U.S.C. § 103 as being obvious over Barrett alone. As to
claims 7 and 8, the examiner rejects these claims on the basis of
Barrett in view of Gonzales.
