Imaging device
An object of the present invention is to provide an imaging device which can reliably correct dark current components that locally occur in an imaging sensor, such as those caused by an FDA. The imaging device includes: a storage unit which pre-stores information representing a relation between one of dark current components and an output signal of an optical black pixel arranged in a predetermined optical black area on an imaging sensor, the dark current components being superimposed on pixel signals of effective pixels, respectively, arranged in a predetermined effective pixel area on the imaging sensor; a dark current obtaining unit which obtains dark current components based on both the information stored in the storage unit and output signal of the optical black pixel; and a correcting unit which corrects the dark current components obtained by the dark current obtaining unit according to the pixel signals.
