In order to make it possible to reduce the noise which is generated in an imaging device 1 in an accurate manner, after the dark current noise has been eliminated from the signal from the imaging device 1 by a black level compensation section 2, noise reduction processing is performed by a noise reduction section 3 and elimination of shot noise is performed, and subsequently white balance compensation is performed by a white balance compensation section 4. When noise reduction processing is performed with this type of structure, it becomes possible to reduce the noise in an accurate manner, since the noise reduction is performed after the black level compensation and moreover before the white balance compensation.
