PROBLEM TO BE SOLVED: To provide a camera operating while switching between an imaging-surface phase difference AF and a contrast AF.SOLUTION: A camera comprises: an imaging device in which pixels for imaging and pixels for focus detection are two-dimensionally arranged on an imaging surface, the pixels for imaging being arrayed over the entire imaging surface and the pixels for focus detection being arrayed on a part of the imaging surface; an imaging optical system; first focusing means which performs focusing by a phase difference detection method on the basis of output signals of the pixels for focus detection; second focusing means which performs focusing by a contrast method on the basis of output signals of the pixels for imaging; image processing means which recognizes a main object; switching prediction means which predicts switching from one to the other of the first and second focusing means on the basis of a positional relationship between the main object and a focus detection area; start-up means which, when the switching is predicted, starts the other focusing means; and switching means which, after the other focusing means is started, switching from the one to the other focusing means. |
