Abstract
A subject detection unit detects a subject and characteristic area included in the subject from an image, a setting unit sets focus detection areas of a predetermined size in the subject and characteristic area, a detection unit detects a focus state in each focus detection area, and a selection unit selects a first area that satisfies a predetermined condition and a second area that includes the characteristic area from the focus detection areas. A prediction unit predicts a focus state of the second area at an arbitrary time based on a first history of focus state of the first area based on the focus states and a second history of difference between the focus states of the first and second areas, and an acquisition unit acquires an actuation amount for focusing on the second area based on the focus state thereof.
