<p>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 (8) that amplifies a signal of the pixel using an amplification factor that is based on a variable feedback capacitor (Cf1, Cf2), a storage capacitor (Ctn, Cts) connected to an output node of the amplifying circuit (8) via a first switch (12, 13), and a load element (C11, C12) connected to the output node of the amplifying circuit (8) via a second switch (16, 17). The second switch (16, 17) is in an on state during any one of or both of a period in which the feedback capacitor (Cf1, Cf2) is reset and a period in which the first switch (12, 13) is in an on state.</p> |
