Appeal No. 95-3282
Application No. 07/758,149
1. A method of enhancing a multi-coloured image, defined by a plurality of colour
components represented by electrical signals respectively representing the value of each
colour component of each pixel of a first resolution version of the image, to produce an
enhanced image, the method comprising, for said each colour component of each pixel,
obtaining a fringe value by determining the difference between the component values at
the first resolution and at a second, lower resolution; determining for each pixel the length
of a vector whose components are defined by values related to the fringe values of that
pixel; and modifying one of each original colour component value and a value derived
from each original colour component value by an amount related to the respective fringe
value in accordance with the relationship of said vector length with a threshold to produce
said enhanced image.
The examiner relies on the following reference:
Ellis et al. (Ellis) 4,724,477 Feb. 9, 1988
Claims 1 through 3, 5 and 6 stand rejected under
35 U.S.C. § 102(b) as anticipated by Ellis. Claims 1 through 6 were finally rejected under
35 U.S.C. § 101 as being directed to nonstatutory subject matter but this rejection has
been withdrawn by the examiner in response to a remand by the Board and it is no longer
before us.
Rather than reiterate the arguments of appellant and the examiner, reference is
made to the briefs and answers for the respective details thereof.
OPINION
Anticipation, under 35 U.S.C. § 102, requires that each
element of the claim in issue be found, either expressly
described or under principles of inherency, in a single
prior art reference. Kalman v. Kimberly-Clark Corp., 713
