PROBLEM TO BE SOLVED: To provide a method for positioning as designed irrespective of a magnitude of the error of an unfixed quantity such as variations of parts, an assembling error in lens moving. SOLUTION: In this method for correcting a lens position in an image pickup device 2, capable of varying a magnification, comprising a lens moving in the optical axis direction and a controller 58A moving a lens based on control data indicating a lens moving amount in correspondence with each of a plurality of setting magnifications, the control data are stored in a memory 61 writable at least once, and an actual magnification is measured when moving the lens, based on the control data stored in the memory 61A, and the control data are corrected in correspondence with an error between the measured magnification and the setting magnification in correspondence with the control data, and the corrected control data are stored in the memory 61A instead of the control data prior to correction.
