ABSTRACT:
In the solid state image pickup apparatus, in order to achieve complete transfer of the charge from the photodiode to the floating diffusion area, there is provided a pickup apparatus having a photoelectric conversion element, a transfer switch consisting of a MOS transistor for transferring the signal charge generated in the photoelectric conversion element, a floating diffusion capacitance for receiving the signal charge through the transfer switch, and a reset switch consisting of a MOS transistor for resetting the potential of the floating diffusion capacitance, the device comprising at least a potential setting circuit for generating a voltage different from the power supply voltage, wherein the output of the potential setting circuit is applied as a pulse to the gate of the transfer switch and/or the gate of the reset switch.
