US Patent 7812801 Imaging apparatus

An aspect of the present invention provides an imaging apparatus comprising: a solid-state image sensor having an effective pixel area and an optical black area; a smear detection device which detects smear intensity and smear occurrence position in a smear occurrence area, in which a smear occurs, in the effective pixel area, based on an output signal obtained from the optical black area of the solid-state image sensor; and a smear correction device which performs smear correction by subtracting a smear correction value corresponding to the smear intensity from an output signal of the smear occurrence area and the vicinity thereof in the effective pixel area.
