Abstract:
A mechanism correcting a trembling of a focused image comprises:a detector that detects an angular speed of a trembling of an optical axis of an optical device;an integrator that converts said angular speed to an angular data of said optical axis by integrating outputs from said detector;a correction optical system that corrects a trembling of a focused image;driving systems that drive said correction optical systems;obtaining systems that obtain a position data of said correction optical systems; anda controlling system that controls said driving systems such that a difference between said angular data of said optical axis and said position data of said correction optical system is canceled; whereinsaid controlling system replaces a value outputted from said integrator with a value substantially equivalent to a value outputted from said obtaining systems, on the occurrence of a predetermined condition.
