Appeal No. 2003-0350
Application 08/771,399
20, 2002 after final rejection was approved for entry by the
Examiner.
The claimed invention relates to image sensing control
in which signals from first and second scan lines are output in
parallel to first and second output amplifiers, respectively,
with each of the amplifiers having different gain
characteristics. A plurality of component signals for forming
image signals from the signals of the plurality of scan lines are
generated and output to a filter. The filter removes the noise
frequency components contained in the component signals caused by
the gain difference between the first and second amplifiers.
Claim 1 is illustrative of the invention and reads as
follows:
1. An image sensing apparatus comprising:
readout unit having a first output amplifier for
outputting a first signal of a first scan line and a second
output amplifier for outputting a second signal of a second scan
line in parallel, from an image pickup unit, wherein said first
and second output amplifiers have different gain characteristics;
generation unit for generating a plurality of component
signals for forming image signals from the signals of the
plurality of scan lines; and
a filter which removes noise frequency components,
caused by gain difference between said first and second
amplifiers, contained in said component signals by removing at
least one of predetermined frequency components in the
