ABSTRACT:
A focus evaluation value representing a focusing state of a taking lens is repeatedly calculated on the basis of an image signal output from an imaging section of a digital camera, a change in the focus evaluation value generated by the movement of the taking lens is detected, when a predetermined change in the focus evaluation value is detected in manual focusing, at least one of a first mode for continuing manual focusing and a second mode for making the transition to auto-focusing, in which the taking lens is automatically moved, is selected, when the predetermined change in the focus evaluation value is detected in the case in which the second mode is selected, the focusing operation is automatically switched to auto-focusing, whereby the taking lens is automatically moved such that the focus evaluation value is the peak value.
