ABSTRACT:
Provided is an amplification type solid state image pickup device capable of increasing a saturation charge amount even when an increase in circuit scale is suppressed. In a pixel of the amplification type solid state image pickup device, a power source voltage is supplied to a signal output line to change a potential of the signal output line at transfer operation that a signal charge accumulated in a photo diode is transferred to a gate of an amplification transistor. Then, a potential of an FD portion which is capacitively coupled to the signal output line and used for supplying the signal charge to the gate of the amplification transistor increases, so that the saturation charge amount can be set to a large value.
