An interchangeable lens acquires position information regarding a focus lens and a zoom lens at a predetermined time interval during an exposure time period of detection information acquisition pixels for use in calculation of a defocus amount (DF), and outputs the position information to an imaging device. The imaging device calculates the defocus amount (DF) by using information regarding the detection information acquisition pixels, calculates a reference focus lens position (Ref_fc) by using points, on a cam curve, corresponding to the inputted lens position information, calculates a target focus lens position (Tgt_fc) in an in-focus position, from the reference focus lens position (Ref_fc) and the defocus amount (DF), and outputs the target focus lens position (Tgt_fc) to the interchangeable lens."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Interchangeable lens device, imaging device, imaging system, method, and program","description":"Provided are a device and a method by which high-precision auto focus (AF) processing can be performed while a focus lens or a zoom lens is being operated.
