Abstract:
An optical device, provided with a tremble preventing function, comprises:a detector that detects an amount of an optical device tremble;a correcting optical system that corrects a tremble of a focused image due to said optical device tremble; anda driving system that drives said correcting optical system in two directions on a plane perpendicular to an optical axis of said correcting optical system, such that said optical device tremble amount is canceled when a tremble preventing operation is performed, said driving system maintaining a position of said correcting optical system when a power supply to said optical device is stopped;wherein said correcting optical system is driven to a moving center position such that said optical axis of said correcting optical system coincides with an optical axis of another optical system of said optical device, when said power supply to said optical device is stopped.
