Appeal No. 95-4361

in a first stage and then the results are summed with another
source component in a second stage. Claim 8 specifies the
conversion as being from the YUV format to the RBG format, and
specifies that the product terms involve the U and V components
of the source data and that the logic means takes as input the Y
component. However, claim 8 does not specifically specify
summing as the operation performed by the logic means.
Opinion
We reverse the rejection of claims 1-14 on the grounds as
applied by the examiner.
Contrary to the examiner’s view, Ishii does not disclose a
two-stage format conversion process wherein the product terms are
generated in a first stage and applied to a logic means in a
second stage, which logic means also takes as input a separate
component of the source data. The appellants are correct that in
Ishii, the look-up table 36 and the logic circuit means 37 (see
Figure 7) operate in parallel in the same manner as the prior art
components 5 and 8 shown in Ishii’s Figure 2. The selector 35 in
Ishii’s Figure 7, as is the selector 6 in Ishii’s Figure 2,
selects which data to provide as output (column 8, lines 11-22)
and is not a logic means which receives a separate component of
