Abstract
A defocus amount is corrected according to the difference between the focus state of an imaging optical system that corresponds to the accumulation period of multiple image signals used to generate an added image signal and the focus state of the imaging optical system when the focal point is adjusted. Here, when calculating the focus state of the imaging optical system that corresponds to the accumulation period of the image signals used to generate the added image signal, the focus state of the imaging optical system that corresponds to the accumulation period of an image signal used to generate the added image signal is weighted higher the higher the sharpness of that image signal is.
