image." We note that Appellant does not simply require any
function of interpolation but requires that the N electrical
signals are interpolated to produce a high definition picture
in a video camera. On page 2-3 and 7 of the specification,
Appellant discloses that an interpolating reproduction unit 70
is for compensating for the time differences of the first and
second images signals to produce a video picture. We note
that the time difference is due to the first image taken prior
in time to the second image signal and compensation is
required to produce a composite video picture. Thus,
Appellant's claim language requires that data points are
interpolated so that a high definition video picture is
produced.
Upon a closer review of Takagi, we agree with Appellant
that Takagi teaches a document scanner in which there is no
need for interpolation between data to generate a high
definition picture. In column 3, lines 5-12, Takagi teaches
that Figures 2 and 3 show an image source 11 which is a
document illuminated by light. In column 3, lines 12-32, the
image source 11 is divided into a plurality of image light
