Abstract:
1. An imaging device comprises: (a) an imaging element configured to generate an image signal of a subject; (b) a contrast detection information acquisition unit configured to detect contrast focus detection information of a contrast detection system based on the image signal; (c) a phase difference detection unit configured to detect phase difference focus detection information of a phase difference detection system; (d) a processing unit configured to (i) store history information of the contrast focus detection information in each focal position while a focus lens is driven by a driving unit based on the phase difference focus detection information, (ii) drive the focus lens to an in-focus position based on the phase difference detection system, and (iii) drive the focus lens to a final focal position by the contrast detection system using the history information after the focus lens is driven to the in-focus position.
