Abstract:
A camera comprising:a photographic optical system having an optical axis;a vibration detection unit that outputs a signal indicative of vibrations in the camera;a photographic focal length detection unit that outputs a signal indicative of a focal length of the photographic optical system;a distance measurement unit that outputs a signal indicative of the distance to an object being photographed;a vibration compensation unit to shift the optical axis of the photographic optical system to compensate for the vibrations detected by the vibration detection unit;a non-volatile rewritable memory that stores a gain-adjustment value which compensates for variation in the individual outputs from the vibration detection unit; anda correct compensating coefficient calculation unit that calculates a correct compensation coefficient based on the output of the photographic focal length detection unit, the output of the distance measurement unit, and the gain-adjustment value stored in the non-volatile rewritable memory, the correct compensation coefficient determining an amount the vibration compensation unit changes the optical axis of the photographic optical system relative to the output of the vibration detection unit.
