Abstract
A solid-state image pickup device includes a pixel including a photoelectric conversion element that converts light into an electric signal, a feedback amplifying circuit that amplifies a signal of the pixel using an amplification factor that is based on a variable feedback capacitor, a storage capacitor connected to an output node of the amplifying circuit via a first switch, and a load element connected to the output node of the amplifying circuit via a second switch. The second switch is in an on state during any one of or both of a period in which the feedback capacitor is reset and a period in which the first switch is in an on state.

A solid-state image pickup device comprising:
- a pixel including a photoelectric conversion element;
- an amplifying circuit configured to amplify a signal of the pixel and to have a variable amplification factor;
- a storage capacitor connected to an output node of the amplifying circuit via a first switch;
- and
- a load element connected to the output node of the amplifying circuit via a second switch,
- wherein the second switch is in an on state during any one of or both of a period in which the amplifying circuit is reset and a period in which the first switch is in an on state.
