A phase difference AF processing unit (19) performs a correlation operation with respect to detection signal groups in first pairs P1, and performs a correlation operation with respect to detection signal groups in second pairs P2. A system control unit (11) compares a difference between a first correlation amount M1 which is a minimum correlation amount between the detection signal groups in the first pairs P1, among obtained results of the correlation operation with respect to the first pairs P1 and a second correlation amount M2 which is a minimum correlation amount between the detection signal groups in the second pairs P2, among obtained results of the correlation operation with respect to the second pairs P2 with a threshold value TH, to thereby determine a reliability of a focusing control based on the phase difference AF method."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging device and focusing control method","description":"The present invention provides an imaging device and a focusing control method capable of performing reliability determination of a phase difference AF at high speed.
