An imaging device includes an imaging unit having an imaging element to conduct photoelectric conversion on incident light from a subject and output an electric signal, a signal gain control unit for controlling an output signal level of the imaging unit, a plurality of defective pixel correction units for correcting defective pixels contained in a signal output from the signal gain control unit, an image signal processing unit for generating an image signal from a signal which is output from the defective pixel correction units, a temperature measurement unit for measuring temperature in the vicinity of the imaging element, and a system control unit for generally controlling the imaging unit, the signal gain control unit, the correction units, and the image signal processing unit. The system control unit uses the plurality of defective pixel correction units jointly and causes them to operate according to occurrence causes of defective pixels. |
