<P>PROBLEM TO BE SOLVED: To solve such a problem that in a lens position detection device, it happens that a lens position is not accurately detected because chattering occurs in a detection signal of detection means. <P>SOLUTION: In a lens position detection device including detection means arranged in a reference position where the movable range of a focus lens group is divided into a first voltage level side and a second voltage level side and detecting the reference position, first, control means stabilizes the operation of drive means of the focus lens group, further, the focus lens group is moved from the vicinity of the switching position of a voltage where a voltage value is unstable, and after the initial excitation of the drive means is completed, the interruption permission of the detection means is performed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
