A controller controls to move a focus position to a lens position obtained from the defocus value and the stored correction value. The first mode is to make a user select an amount for shifting the focus position, and the correction value is obtained according to the selection. In the second mode, imaging and detection of the defocus value are performed at each of different focus positions, and the correction value is obtained from a defocus value corresponding to selected one of obtained images. A minimum unit of the correction value in the second mode is larger than that in the first mode."},"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 detection unit detects a defocus value, a correction value for shifting an in-focus position that is based on the defocus value is obtained by first or second method and stored in a memory.
