according to address signal from the address

for data processing can be significantly reduced
(column 4, lines 2 through 9).
While we agree with the examiner that Iwasaki discloses
"an image display means for reproducing the respective images
from image signals which represent the respective images and

represented by only the image signal components of a
corresponding image which have signal values "larger than a
predetermined threshold value" (claims 1 and 9). Iwasaki is

21 and 22 are superposed to form one synthesized simple image
23, and not "a" simple image for "each" of the two images 21
