A solid-state image pickup device comprises for each pixel a photoelectric converter
PD, an input terminal FD of a signal amplifier and a transfer switch TX for transferring
an optical signal from the photoelectric converter to the input terminal. The device
additionally comprises means for resetting the photoelectric converter by opening
the transfer switch TX under a condition of holding the voltage of the input terminal
FD to a fixed high level before storing the optical signal in the photoelectric
converter PD. With this arrangement, any residual electric charge in the photoelectric
converter can be eliminated without paying the cost of reducing the manufacturing
yield and degrading the chip performance.
