components of the edge region of the input image. In the
Examiner’s view, the skilled artisan would find it obvious to
integrate the high frequency components of Takemoto for
normalization purposes in view of the image sharpening
teachings of Yamada.
In response, Appellant asserts (Brief, page 11) a lack of
motivation for modifying the prior art in the manner suggested
by the Examiner. We agree. As discussed previously, the
Examiner relies on Yamada for teaching the integration of
extracted high frequency components of an image signal to
sharpen the image of such signal. Despite the Examiner’s
assertions (Answer, page 6) to the contrary, however,
Takemoto’s edge detecting and filtering feature makes no
mention of the extraction of high frequency components. This
reason alone makes the Examiner’s suggested motivation for
adding the integrator of Yamada to Takemoto problematical at
best.
Further, aside from the general assertion that it would
be obvious to add an integrator to Takemoto, the Examiner has
not indicated how and where such integrator would be coupled
to the prior art circuitry of Takemoto to achieve the claimed
