Abstract

An imaging elementincludes an imaging pixeland phase difference detecting pixelsR andL. When there is an instruction to start capturing a moving image, a defocus amount calculating unitdetermines a shift amount of two output signal groups at the time of performing a correlation operation in accordance with information of an F value, a focal distance, and a focal position. The defocus amount calculating unitshifts two output signal groups by a unit amount within a range of a determined shift amount to perform a correlation operation and calculates a defocus amount from the result. Thereafter, when the distance to a major subject varies, the defocus amount calculating unit changes the shift amount which has been already set to a larger value.
