Abstract
To suppress voltage variations due to transistor switching noise in a solid-state image sensor including a transistor that initializes a differentiating circuit. A capacitance supplies a charge corresponding to an amount of variation in a predetermined pixel voltage to a predetermined input terminal. A voltage output unit outputs, as an output voltage, a voltage corresponding to an input voltage at the input terminal from a predetermined output terminal. A reset transistor supplies one of a positive charge or a negative charge during a predetermined period to control the output voltage to an initial value in a case where initialization is instructed. A charge supply unit supplies the other of the positive charge or the negative charge when the predetermined period elapses.
