Zusammenfassung:A fixed-pattern noise elimination apparatus 4 eliminates a fixed-pattern noise component resulting from dark current out of an image signal outputted from an effective pixel of a solid-state image sensor 2 during image sensing, by using: a first dark current that is calculated based on a previously acquired signal outputted from a light-shielded pixel of the solid-state image sensor 2 and that is stored in a compensation data memory 6; a second dark current that is calculated based on a previously acquired signal outputted from the effective pixel of the solid-state image sensor 2 with no incident light and that is stored in the compensation data memory 6; and a third dark current that is calculated based on a signal outputted from the light-shielded pixel of the solid-state image sensor 2 during image sensing. With this configuration, a fixed-pattern noise component resulting from dark current can be effectively eliminated irrespective of the temperature of the solid-state image sensor.
