Appeal No. 2000-2184
Application 08/629,626
the invention reads images from a film and extracts signals
caused by the graininess of the film. These signals are used to
calculate a contrast value which, in turn, is used to adjust the
focus of the film.
Representative claim 1 is reproduced as follows:
1. A film image reading method, comprising:
reading the film image to create image signals,
extracting signals caused by a graininess of the film
from the image signals read, wherein film grainess is a
characteristic attributed to particles forming the film,
calculating an image contrast value based on the signals
extracted, and
adjusting a focus of the film using said image contrast
value.
The examiner relies on the following references:
Yamada et al. (Yamada) 5,212,516 May 18, 1993
The admitted prior art described in appellant’s specification.
Claims 1-26 and 30-32 stand rejected under 35 U.S.C.
§ 103. As evidence of obviousness the examiner offers Yamada in
view of the admitted prior art.
Rather than repeat the arguments of appellant or the
examiner, we make reference to the brief and the answer for the
respective details thereof.
