Appeal No. 96-0654
Application 08/103,207
includes four windows 14A, 14B, 14C and 14D which are opened
in turn in a predetermined time order so that a component of
image light passes through the opened window and focuses on
light sensor 12. In column 3, lines 44-49, Takagi discloses
that the light sensor 12 can generate four partial image
signals corresponding to the four partial image sources 11A,
11B, 11C and 11D which composed into one image signal in a
memory not shown. Takagi teaches in column 3, lines 50-60,
that the apparatus has four times the resolution of an
apparatus which does not have shutter 14 and compound eye lens
14. Takagi further states in column 3, lines 57-60, that
"[a]s a result, by use of the method of this embodiment, a
light sensor equivalent to a high density light sensor can be
obtained by use a low density light sensor." In other words,
Takagi teaches that a high resolution is obtained by
increasing the resolution of light sensor 12 by sensing only
one fourth of the document at a time. Takagi does not teach
or suggest the use of interpolation to increase the resolution
of the apparatus nor does Takagi recognize any problem of time
differences between the when each one fourth of the document
is sensed. It is clear that Takagi does not suggest that time
