Appeal No. 96-0281
Application 08/248,625
a compressed signal when said amount exceeds a predetermined
threshold. We recognize that Sakata's abstract states that
based upon the remaining amount of capacity, image data is
compressed and reduced. However, Sakata teaches in column 13,
lines 26 through 31, that the operator enters a desired
compression ratio on the operation board by using numerical
keys or dip switches. In column 13, lines 45 through 49,
Sakata teaches that if one tries to store data in the memory
without compressing them, despite the limited memory capacity,
a code indicative of short memory capacity is applied to the
main controller so as to provide such a message on the opera-
tion board. Therefore, Sakata does not teach a system which
determines the compression ratio, but instead this is deter-
mined by the operator. Therefore, Sakata fails to teach or
suggest a memory management unit determining the amount of
data stored within the memory means and generating a com-
pressed signal when said amount exceeds a predetermined
threshold as claimed by Appellant.
