The imaging unit receives and photoelectrically converts a light flux passed through a photographing optical system including a focus lens. The first detection unit detects a phase difference between a pair of image signals output from the imaging unit. The second detection unit detects contrast information from a signal output from the imaging unit. The control unit controls driving of the focus lens based on a detection result of at least one of the first detection unit and the second detection unit. If the detection result of the first detection unit satisfies a first condition, the control unit controls driving of the focus lens by using the detection result of the first detection unit, and changes the first condition according to the contrast information detected by the second detection unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focus adjustment apparatus, method for controlling focus adjustment apparatus, and storage medium","description":"A focus adjustment apparatus includes an imaging unit, a first detection unit, a second detection unit, and a control unit.
