Apparatus for eliminating noise in a solid-state image pickup device |
摘要 |
A solid state image pickup apparatus having a selector for selecting a plurality of sensor outputs through predetermined circuits includes a difference processing circuit for calculating a difference between a selected sensor signal and a reference signal selected through the same predetermined circuit as that of the selected sensor signal. The difference processing circuit includes a first holding circuit for holding the sensor signal, a second holding circuit for holding the selected reference signal, and a circuit for receiving the output signals from the first and second holding circuits and outputting a signal corresponding to a difference therebetween.
