Application No. 08/061,225
set in the setting step of gradation characteristic," though
as stated above he believes that Asada does not disclose
selecting such coefficients.
Appellants assert (Brief, page 9) that
Asada does not describe how the basic masking
circuit operates or how the masking coefficients are
chosen. Asada does not disclose that the masking
coefficients used by the masking circuit are changed
at all and certainly does not disclose that the
masking coefficients are changed according to the
gradation curve. (emphasis in original)
We agree. The examiner refers to column 4, lines 50-65, of
Asada (Final Rejection, page 6) as support for his assertion
that Asada discloses setting the masking coefficients
according to the gradation characteristic. However, the
portion cited in Asada merely discloses that "gradation curves
are determined" first in the color correction circuit.
Nowhere does Asada describe selecting or changing the masking
coefficients. Consequently, we must agree with appellants
that Asada does not disclose changing the masking coefficients
according to the gradation curve, nor
any correspondence between the coefficients and the gradation
curve.
