摘要： A blur prevention device is equipped with first and second drive units which can move a blur prevention lens in a plane orthogonal to an optical axis of a main optical system. First and second transfer units transfer the amount of movement of the drive units to the blur prevention lens and first and second transfer receiving units receive the amount of movement in the respective directions from the respective transfer units. Each of the transfer receiving units can move relative to the one transfer unit other than the respective transfer unit. The blur prevention device has a specified direction for one of the transfer units and allows a degree of freedom outside the movement in the specified direction to the other transfer unit. Restriction gears, which are part of the drive units, restrict the amount of movement of the blur prevention lens in the plane orthogonal to the optical axis. And, by integrating a lens shutter or aperture with the blur prevention device, the blur prevention lens may be easily positioned in a central position of its drive range.

摘要： A vibration correction system in a camera which detects vibration of the camera caused, e.g., by a hand tremor, and corrects for the vibration of an image in an image plane caused by vibration of the camera. The vibration correction system includes a vibration sensor which detects vibration of the camera, and a vibration correction optical system which is driven to correct for the detected vibration. When an anomaly occurs in the vibration detection sensor, in the vibration correction optical system, or in the drive system of the vibration correction optical system, the operation of the vibration correction optical system is inhibited. The vibration correction optical system also adjusts for correction error resulting from chatter in a gear mechanism of the drive system of the vibration correction optical system by controlling shutter timing. The vibration correction optical system further adjusts for correction error resulting from a delay in the output of the vibration detection sensor by controlling shutter timing in order to minimize the error caused by the delay.
