Abstract

An imaging device and a focusing control method are provided. The imaging device includes: an imaging element, having pixels including phase-difference detecting pixels and imaging a subject through an imaging optical system including a focus lens; and a focusing controller, selectively performing focusing control using a phase difference AF method or focusing control using a contrast AF method in a mode in which focusing control for focusing on a main subject by driving the focus lens is continuously performed multiple times. The focusing controller performs the focusing control using the contrast AF method in a case where a state in which a degree of reliability of the focusing control using the phase difference AF method is equal to or less than a threshold value persists N times (N=2 or more), while the focusing control using the phase difference AF method is continuously performed.
