Abstract:
1. An imaging device comprising: a lens unit including a zoom lens and a focus lens; an imaging element adapted to receive light from a subject at a subject distance from the lens unit input through the lens unit to perform imaging; a zoom drive section adapted to move the zoom lens in an optical axis direction to vary a focal distance; a focus drive section adapted to move the focus lens in the optical axis direction to vary a focus state; a focus control section adapted to make the imaging element perform imaging while making the focus drive section change a position of the focus lens to detect a focal position based on an imaging result of the imaging element, and perform focusing based on the focal position detected; and a storage section that stores a plurality of focal positions each corresponding to a subject distance and a zoom lens position, wherein the focus control section detects the focal position and obtains the subject distance corresponding to the detected focal position and current zoom lens position from the storage section, in a state in which the zoom lens is positioned on a telephoto side of a predetermined reference position using the zoom drive section, and then moves the zoom lens to the predetermined reference position after the detection, and adjusts the focal position of the focus lens to a focal position, which is obtained from the storage section, that corresponds to the obtained subject distance and the predetermined reference position of the zoom lens.
