pixel size of the display.1 In the examiner’s opinion, transforming the pixels to effect an
increase or a decrease in size would have been equally obvious.
Moreover, by one interpretation that appears consistent with one of the alternative
definitions provided in the specification (at 32), the language of claim 5/1 appears to say
that as the read out image size becomes large -- and, in Sayed, the CCD pixel size
becomes smaller -- then the transformed pixel density is lowered -- and thus the
transformed pixel size is increased, as in the reference, because the pixel size in the
display is presumed to be larger than the 15x15 micrometers basic size in the CCD
device.
We will sustain the rejection of claims 5/1, 6/1, 12/8, and 13/8 under 35 U.S.C.
§ 103 as being unpatentable over Sayed. We do not hold that Sayed teaches all of the
subject matter embraced by representative claim 5/1. Sayed, however, teaches a
“transforming process” having the same input and result that is taught by appellant, with
respect to the displayed output of an image signal that is input from a CCD chip, which is
sufficient to demonstrate the unpatentability of the claim.
1 One inch equals 2.54 cm, 25.4 mm, or 25,400 micrometers. A display of 12 inches in height,
with a resolution of 1024 (horizontal) x 768 (vertical) pixels, has a pixel size of about (12 X 25,400) / 768 =
397 micrometers.
