Abstract:
A photographing apparatus and method are provided that can reduce power consumption by detecting a high precision focusing position for a predetermined range and controlling light emission according to a driving mode when performing focus control. The photographing apparatus includes: a lens movable in an optical axis direction and that focuses a subject image on an imaging surface; a photoelectric converter that converting the subject image into an electric signal; a focusing position detector for detecting a focusing position of the focus lens when at least one main subject image of the subject images is focused on the imaging surface; a focus control unit for controlling a first drive of the focus lens and a second drive of the focus lens that is different from the first drive; a light emitting unit; and a light emitting control unit for controlling for different light emissions during the first and second drive.
