Abstract

See full text

A focus adjusting apparatus detects a first area of a subject and reliability of a tracking position from an image signal output from an image sensor on which a subject image is formed by an optical system, detects focus states of focus detection areas based on the image signal, determines an in-focus area for which focus adjustment of the optical system is to be performed, predicts a focus state in next focus detection based on a history of focus states of the in-focus area, and selects a second area from the focus detection areas. The first area is determined as the in-focus area in a case where a state in which the reliability is higher than a predetermined first threshold continues for a predetermined time period or longer, and the second area is determined as in-focus area otherwise.
