Patent number: 9380204Abstract: An imaging element 5 includes an imaging pixel 51 and phase difference detecting pixels 51R and 51L. When there is an instruction to start capturing a moving image, a defocus amount calculating unit 19 determines 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 unit 19 shifts 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.Type: GrantFiled: September 28, 2015Date of Patent: June 28, 2016Assignee: FUJIFILM CorporationInventor: Hiroshi Endo
