A digital camera includes a phase difference calculation unit which calculates the phase difference between a signal group output from a plurality of pixels 52A and a signal group output from a plurality of pixels 52B, a lens drive control unit which drives a focus lens according to a drive amount corresponding to the phase difference, a phase difference prediction unit which, based on a coefficient for converting a phase difference calculated at an arbitrary time to a drive amount and the difference between a movement amount of the focus lens and the drive amount, calculates a predicted value of the phase difference."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Focusing control device, focusing control method, focusing control program, lens device, and imaging device","description":"Disclosed are a focusing control device which performs focusing control by a phase difference AF method with high accuracy, a lens device, an imaging device, a focusing control method, and a non-trans","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9838593","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
