To provide a solid-state image pickup device that can image all pixels at the same timing, and allows a poststage circuit to determine whether a pixel output is a black-and-white-inverted output.

When a MOS transistor 5 is turned on, an electric signal obtained by a photoelectric conversion circuit 100 is sampled and held by a capacitor C2. In this case, when light incident to the photoelectric conversion circuit 100 has extra-high luminance, a charge leak occurs from the capacitor C2 for generating the black-and-white-inverted output. However, different read timing is set between continuous frames, thus comparing outputs of the continuous frames, and determining whether the black-and-white-inverted output is generated.
