Abstract: An imaging device includes: a solid-state image sensor including: a plurality of pixels that are arranged in a two-dimensional array; and a signal processing device that processes an output signal from the solid-state image sensor. The imaging device generates a corrected image by: generating a correction signal based on a difference between a first temporary correction signal and a second temporary correction signal, the first temporary correction signal being obtained by directly applying a first voltage amplitude to a signal storage provided in each of the plurality of pixels, and the second temporary correction signal being obtained by applying, to the signal storage, a second voltage amplitude that is different from the first voltage amplitude; acquiring an image signal upon a photographing drive operation being performed by the solid-state image sensor; and applying the correction signal to the image signal.
