1. A control device, comprising:
a calculation unit configured to calculate a focus position of each phase difference detection region of a plurality of phase difference detection regions of a subject image based on a result of capture of the subject image,
wherein the subject image is captured by an imaging element via a focus lens; and
a determination unit configured to:
determine whether a number of phase difference detection regions, whose focus positions is within a specific range, in a set of phase difference detection regions of the plurality of phase difference detection regions is greater than or equal to a specific threshold; and
determine a position of the focus lens based on:
the determination that the number of phase difference detection regions in the set of phase difference detection regions is greater than or equal to the specific threshold, and
an average value of the calculated focus position of each phase difference detection region of the plurality of phase difference detection regions,
wherein the average value is within a specific range, on an infinity side or macro side, from the focus position.
