Abstract
The read out of a signal from an imaging device is conducted during a voltage read out mode, and resetting of a signal output line is carried out each time a signal of a plurality of pixels is read out. Signal charge is accumulated on the signal output line, and is then read out. The accumulated signal is differenced or differentiated at a later stage to reproduce an original signal.
