Abstract
In order to provide a solid state image pickup device in which an offset voltage in an image signal from which a noise signal is removed is made to be low, when an image pickup operation is performed while the MOS transistor Tis ON, after a signal φVD with a value Vh is integrated by a capacitor C, the signal φVD is Vm (Vm<Vh) and a pulse signal φV is given so that an image signal is output. When dispersion of sensitivity is detected while the MOS transistor Tis OFF, after the signal φVD with the value Vh is integrated by the capacitor C, the signal φVD is V(V<Vm) and the pulse signal φV is given so that a noise signal is output.
