An object image is formed on the focal plane by the photographing optical system, and when an optical axis of a correction lens is coaxial with an optical axis of other optical systems included in the photographing optical system, the optical axis of the photographing optical system pierces through a center of the focal plane. On the focal plane, a correctable range of the correction lens is defined based on a structure of a correction device. An original point of the correctable range is the center of the focal plane. If a focused image tremble occurs out of the correctable range, an intersection of a boundary of the correctable range and a straight line connecting a position of the optical axis of the photographing optical system and the original point is calculated. The optical axis of the photographing optical system is supposed to be moved to the intersection, then the correction of the focused image tremble is carried out. | |
