Appeal No. 2000-2057
Application 08/838,791
Gahang. Finally, appellant argues that there is no teaching of
the claimed storing step during a first mode of operation in
Gahang [brief, pages 20-23].
The examiner responds that the portion of Augusti relied
on in the rejection relates to shading correction and not to
half-tone processing [answer, pages 13-14].
We will not sustain this rejection of claims 1-10 because
we agree with appellant that the values stored in advance in
EPROM 32 of Augusti do not constitute a preset maximum brightness
value as claimed. Augusti describes these preset values as
resulting from a ratio between the direct reading signal of a
pixel and that recorded in the RAM 31 in the preliminary reading
of the corresponding pixel of the sample strip 29 [page 5]. Both
of these values which make up the ratio are measured values and
not maximum values preset by the user. Although these stored
values may have a theoretical maximum, the system of Augusti does
not preset this theoretical maximum in the memory. As noted
above, one of the key features of appellant’s invention is to
avoid the calculation of shading factors based on measured
parameters.
