Abstract
A solid-state image sensor circuit includes a solid-state image sensor, an optical system, an amplifier, a hold circuit, and an A/D converter. In the solid-state image sensor, some of light-receiving elements are shielded from light. The optical system forms an image on the solid-state image sensor. The amplifier amplifies an output from the solid-state image sensor. The hold circuit holds an output from a shielded portion of the solid-state image sensor. The A/D converter A/D-converts an output voltage from the hold circuit using the output from the amplifier as a lowest analog reference voltage.
