Application 08/838,791
perform half-tone processing in view of the admitted prior art
[answer, pages 3-6].
Appellant argues that the white shading corrected signal
of Nosaki does not correspond to the claimed preset maximum
brightness, and the white shading value for subscanning does not
correspond to the claimed image data sequentially read from said
shading memory unit as asserted by the examiner. Specifically,
appellant argues that the result of averaging in Nosaki does not
constitute a preset value as claimed. Appellants argue that the
features of the controller as recited in claim 1 are not obvious
in view of the proposed combination of Ito, Nosaki and the
admitted prior art. Appellant also argues that the examiner has
provided no support for his statement that combining the
teachings as proposed would increase the utility of the Ito-
Nosaki apparatus. Finally, appellant argues that none of the
applied prior art teaches producing a half-tone image from said
shading compensated image data produced from said shading
compensation unit [brief, pages 7-15].
The examiner responds that the admitted prior art clearly
establishes that prior art systems performed both half-tone
processing and shading compensation. The examiner also responds
that the average of 16 white pixels in Nosaki is ideally a preset
