ABSTRACT:
An operational state of C-AF processing is judged. If the operational state is judged to not be a focused state, when the operational state is a state of fine adjustment, only a range in a vicinity of a current position of a focus lens is searched, and a focused state is set. When the operational state is a state where the focus lens is being driven to a focus position, only a range in a vicinity of a focus position already been detected is searched, and the focused state is set. When the operational state is a state during searching for a peak, searching is carried out in a current driving direction from a current position of the focus lens, and the focused state is set. When the operational state is none of above states, an entire region is searched, and the focused state is set.
