To correctly correct exposure amount difference in a frame even in the case of continuously operating a diaphragm within one frame in an imaging device for driving an imaging element by a rolling shutter method during moving image recording and photographing.
An imaging device having an imaging element in which a plurality of photoelectric conversion elements for photoelectrically converting light made incident through an aperture and outputting an image signal are two-dimensionally arranged calculates a reference integrated value (ΔS(n)) being a time integrated value of a relative aperture stopping amount to a reference aperture stopping amount of the aperture during an accumulation time in a reference row of the imaging element and a row integrated value (ΔS(k)) being a time integrated value of a relative aperture stopping amount during an accumulation time in each row other than the reference row about a frame with the aperture changed in the case where the aperture changes when driving the imaging element by a rolling shutter method, and corrects an image signal outputted from the frame so as to correct a difference between the reference integrated value and the row integrated value on the basis of the reference integrated value and the row integrated value.
