Abstract
A solid-state image pickup device includes a plurality of common output lines receiving signals from a plurality of pixels, a plurality of column amplifier units amplifying the signals, a plurality of storage capacitors storing the amplified signals, a first transistor controlling electrical conduction between the output node of the column amplifier unit and the input node of a storage capacitor, a switch switching current for operating the column amplifier unit between a first current and a second current smaller than the first current, and a controller inhibiting, while the second current is flowing through the column amplifier unit, a potential at the output node of the column amplifier unit from approaching an off-state voltage supplied to a gate of the first transistor in an OFF state of the first transistor.
