<P>PROBLEM TO BE SOLVED: To provide a lens position detecting device capable of shortening a lens reference position detecting time. <P>SOLUTION: A lens position detecting device 100 comprises: a lens 101; lens driving means 111 for moving a lens in an optical axis direction; lens drive command means 112 for outputting a drive command to the lens driving means; position detecting means 102 for detecting that the lens is located at a predetermined position; and a first reference position detecting means 105 for moving the lens to a first position upon starting a detecting operation, for receiving thereafter an output signal from the position detecting means while moving the lens in one direction along the optical axis direction from the first position, and for detecting a reference position of the lens, on the basis of the output signal. <P>COPYRIGHT: (C)2013,JPO&INPIT |
