indicate that it was known in the art to use spotwise and average
photometric techniques to control the exposure in accordance with
the average brightness of the object viewed. As relied upon by
the examiner in formulating this rejection, the teachings at
column 2, lines 39-48 of Tsunefuji indicate that cameras having
automatic exposure control were known in the art. Since the
brightness of an object was stated to be one of the exposure
factors originally discussed at the bottom of column 1 of
Tsunefuji, an automatic exposure control camera relying upon a
variation of the exposure period is indicated as a means to
control the level of exposure such as to make it constant over
variable brightness conditions. The artisan would have well
recognized that the exposure period is effected by the shutter
speed of the camera. Even though the specific teachings of
Tsunefuji relate to a film-type camera rather than a CCD type
camera of Iwai's element 10 in Figure 1, the generic or generally
known teachings about automatic exposure control relied upon by
the examiner and noted at columns 1 and 2 of Tsunefuji would have
been obvious to have been incorporated in the processing of the
image relative to the exposure times of the CCD camera 10 in
Iwai. Thus, we consider that it would have been obvious for the
artisan to have combined the teachings of Tsunefuji with those of
