A first computation unit computes a contrast determination index that indicates contrast of an object based on an image obtained through an image pickup optical system. A second computation unit computes a focusing degree that indicates a degree of a focusing state to the object based on the image. A first setting unit sets up a contrast determination threshold according to the focusing degree. A second setting unit sets up an image pickup cycle for picking up the object according to the contrast determination index and the contrast determination threshold. A focusing unit focuses on the object by driving a focusing lens of the image pickup optical system along an optical axis based on the contrast determination index and the focusing degree."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focusing device, control method therefor, storage medium storing control program therefor, and image pickup apparatus","description":"A focusing device that is capable of shortening focusing time even when contrast AR is started for an object in a defocus state.
