Abstract: An imaging device acquires first dark image data in a state where an image sensor has been light shielded, acquires second dark image data in a state where the image sensor has been light shielded, based on completion of exposure, corrects fixed pattern noise of a reference combined image data based on at least one of the first dark image data and the second dark image data, and stores the reference combined image data that has been subjected to correction.
