Patent number: 11570353Abstract: There is provided a focus adjustment apparatus. A selection unit repeatedly executes selection processing for selecting a main subject from one or more subjects included in a shooting range based on an autofocus (AF) setting. A focus adjustment unit performs focus adjustment on a target position determined based on the selected main subject. A change unit changes the AF setting. In a case where the AF setting is changed after a previous execution of selection processing, the selection unit determines whether to execute selection processing based on a main subject selected in the previous execution of selection processing or whether to execute the selection processing independently of the main subject selected in the previous execution of selection processing according to a change content of the AF setting.Type: GrantFiled: May 2, 2022Date of Patent: January 31, 2023Assignee: Canon Kabushiki KaishaInventor: Akiko Wada
