<P>PROBLEM TO BE SOLVED: To provide an imaging device which can correct focus with constant sensitivity by moving an imaging element. <P>SOLUTION: An imaging device comprises: a zoom lens for zooming movement; a focus lens for focus adjustment; an imaging element which moves in the optical axis direction with the zooming movement; memory means to store, for a plurality of subject distances, position information of the focus lens which corresponds to a zoom position to maintain a focus position at the time of the zooming movement, and position information of the imaging element which corresponds to the zoom position to maintain the focus position at the time of the zooming movement; an optical filter configured to be inserted into and retreated from an optical path; optical filter detection means which detects a state of the optical filter; and correction means which corrects focus by moving the imaging element in the optical axis direction according to the optical filter state detected by the optical filter detection means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
