The correction value obtained by the second method is converted to a correction value of the first method by changing units, and the correction value obtained by the first method or the converted correction value is stored in a storage unit. A control unit controls driving of a focus lens to a lens position based on a value obtained by correcting the defocus value by the stored correction value. In the second method, a user selects one of a plurality of images obtained by driving the focus lens, and the correction value is calculated based on the defocus value of the selected image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focus detection apparatus and control method for the same","description":"A focus detection unit detects a defocus value, and a correction value for shifting an in-focus position based on the defocus value is obtained by a first method or by a second method.
