Abstract:
A device for correcting a tremble of a focused image comprising:a tremble detector that detects a tremble of optical axes of an optical device; correction optical systems that correct said tremble of said optical axes; driving devices that drive said correction optical systems; a controlling system that controls said driving devices in such a manner that a tremble of a focused image of an object due to said tremble can be canceled; a reverse detector that detects a reverse of a direction of said optical axes tremble, detection of said reverse detector being repeatedly performed at a predetermined time interval; and a measuring system that measures a time interval, from a previous moment at which said reverse was detected, to a present moment at which said reverse is detected; wherein said controlling system stops said driving devices if said time interval is shorter than a predetermined value.
