Abstract:
1. A solid-state image pickup device comprising a photoelectric converter which stores an electric charge, an input terminal for a signal amplifier, a transfer switch for transferring an electric charge from the photoelectric converter to the input terminal, and a reset switch for applying a reset voltage to the input terminal, wherein said device is adapted to operate such that a pulse signal is input to each of the reset switch and the transfer switch to turn on said reset switch and said transfer switch together at least in a predetermined period, thereby first to reset an electric charge at said photoelectric converter, and such that after an electric charge is again stored in the photoelectric converter and then transferred to the input terminal for a signal amplifier, a pulse signal is again input to each of the reset switch and the transfer switch to turn said switches on together at least in a predetermined period, thereby to reset a second time an electric charge at said photoelectric convertor, both said first and said second resetting of an electric charge being carried out for each frame.
