PROBLEM TO BE SOLVED: To effectively achieve both optical axis control for varying a convergence distance and image blur correction control .SOLUTION: In a lens system, two lens devices each include: vibration detection means; correction command generation means for driving an optical element bending an optical axis so as to correct an image blur; convergence command generation means for driving the optical element so as to form a convergence angle; maximum correction amount arithmetic means for computing an image blur-correctable maximum correction amount on the basis of a convergence command signal; effective maximum correction amount holding means for holding an effective maximum correction amount based upon a maximum correction amount of each lens device; and control means for driving the optical element on the basis of a correction command signal, the convergence command signal, and the effective maximum correction amount, and driving the optical element driving means on the basis of the convergence command signal when the correction command signal exceeds the effective maximum correction amount or the convergence command signal and correction command signal when not. The same effective maximum correction amount is set in an effective maximum correction amount holding means of each lens device for correction in the same direction. |
