<p>The present invention, employing a method of obtaining a final focus position by re-driving a lens before an actual image sensing operation in the vicinity of a focus position which has been obtained by the hill-climbing focusing method, has as its object to enable accurate focusing even in a case where a focus position is not yet obtained by the hill-climbing focusing method. To achieve this object, the driving range of the focus lens at the time of actual exposure is changed in accordance with whether or not AF operation in the hill-climbing mode has been completed and a peak position has been detected. Furthermore, a focus evaluation value is compared with a predetermined value, and the driving range of the focus lens at the time of actual exposure is changed in accordance with the comparison result.</p> |
