Abstract
A focusing control device that can keep a moving subject in focus and can prevent significant defocusing of a low contrast subject or under a low-light intensity condition during continuous shooting. The focusing control device determines whether an in-focus position of a focusing lens can be obtained, predicts an in-focus position for the current exposure operation based on an in-focus position for the previous exposure operation when continuous main exposure operation is performed for shooting, and determines whether prediction of an in-focus position is possible. When prediction of an in-focus position for the current exposure operation is determined to be not possible, the focusing control device performs a scan operation to obtain an in-focus position based on an in-focus position of the previous exposure operation where obtaining of an in-focus position of the focusing lens was determined to be possible.
