    Abstract: To improve the correction accuracy in a solid-state image sensor that performs dark current correction. A solid-state image sensor includes a bias voltage supply unit and a signal processing unit. The bias voltage supply unit supplies a bias voltage of a predetermined value to a light-shielded pixel impervious to light in a period in which a light-shielded pixel signal is output from the light-shielded pixel, and supplies a bias voltage of a value different from the predetermined value to a photosensitive pixel not impervious to light in a period in which a photosensitive pixel signal is output from the photosensitive pixel. The signal processing unit executes processing of removing dark current noise from the photosensitive pixel signal using the light-shielded pixel signal.
