Claim Text:
1. A focusing control device comprising: a scan control unit configured to perform a scan operation to sequentially acquire a focus evaluation value from an image signal by moving a focusing lens; a focus determination unit configured to determine whether an in-focus position of the focusing lens can be obtained based on the focus evaluation value; a prediction unit configured to predict an in-focus position for a current exposure operation based on an in-focus position for a previous exposure operation, the prediction of an in-focus position being performed when a continuous main exposure operation is performed for shooting an image; and a prediction determination unit configured to determine whether prediction of the in-focus position is possible, wherein, when the prediction determination unit determines prediction of in-focus position for the current exposure operation is not possible, the scan control unit performs the scan operation to obtain an in-focus position based on an in-focus position of the previous exposure operation at which obtaining of an in-focus position was determined to be possible by the focus determination unit.
