There is stored information on a position of a focus lens corresponding to a position of a zoom lens, which is dependent on an object distance. The focus lens is moved based on the stored information when the zoom lens is moved. When a moving direction of the zoom lens is switched, the focus lens is stopped, and then the moving direction of the zoom lens is switched. The focus lens is moved based on the stored information after the switching."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image pickup apparatus and storage medium including focus lens control","description":"An image pickup apparatus which is capable of being downsized and being power-saved, and is capable of following the focal plane and controlling the exposure during the variably-magnifying operation.
