Claims
- 1. An image blur prevention apparatus comprising:
- an image blur prevention device that prevents image blur;
- a predicting portion that anticipates a movement of at least one camera component, the movement of which is responsive to operation of an operating portion of a camera and generates a shock fluctuation; and
- a control device that controls said image blur prevention device so as to limit a range of operation of said image blur prevention device at a time when said predicting portion anticipates a movement of the at least one camera component that generates a shock fluctuation.
- 2. A camera to which an image blur prevention apparatus is adapted, said camera comprising:
- an operation portion;
- at least one component moveable in response to operation of said operation portion, the movement of which generates a shock fluctuation;
- a predicting portion that anticipates a movement of said at least one component; and
- a control portion that controls the image blur prevention apparatus so as to limit a range of operation of the image blur prevention apparatus at a time when said predicting portion anticipates a movement of the at least one component that generates a shock fluctuation.
- 3. An image blur prevention apparatus for use with a camera including a member and with a fluctuation detection sensor that generates an output signal having at least a first frequency component and a second frequency component, said apparatus comprising:
- a control device that modifies the output signal by limiting the second frequency component when the member of the camera enters a state in which the member generates a shock fluctuation, and thereby forms a driving signal, different than the output signal;
- an image blur prevention device for preventing image blur in accordance with the driving signal.
- 4. A camera for use with a fluctuation detection sensor that generates an output signal having at least a first frequency component and a second frequency component and with an image blur prevention apparatus that prevents image blur in accordance with a driving signal, said camera comprising:
- a member capable of generating a fluctuation of said camera; and
- a control portion that modifies the output signal of the fluctuation detection sensor by limiting the second frequency component when said member generates a fluctuation and thereby forms a driving signal that is different than the output signal.
- 5. A camera to which an image blur prevention apparatus and an operating portion is adapted, said camera comprising:
- a predicting portion that anticipates generation of a shock fluctuation in the camera in response to an operation of the operating portion that starts photography in said camera; and
- a control portion that controls operation of the image blur prevention apparatus so as to limit a range of operation of the image blur prevention apparatus during a time when the shock fluctuation is generated in the camera.
- 6. A fluctuation detection apparatus for use with a camera having an operating portion, comprising:
- a fluctuation detection device that detects a fluctuation of a camera and generates an output signal, said fluctuation detection device having a changeable portion;
- a predicting portion that anticipates generation of a shock fluctuation in the camera in response to an operation of the operating portion that starts photography in the camera; and
- a control device that controls the changeable portion of said fluctuation detection device in response to a prediction by said predicting portion, so that the fluctuation detection device suppresses an influence of the shock fluctuation on generation of the output signal by said fluctuation detection device.
- 7. A fluctuation detection apparatus according to claim 6, wherein the changeable portion generates an electromagnetic field.
- 8. A camera to which a fluctuation detection apparatus including a fluctuation detection device for detecting a fluctuation of the camera is adapted and to which an operating portion is adapted, the fluctuation detection device having a changeable portion and producing an output signal, said camera comprising:
- a predicting portion that anticipates generation of a shock fluctuation in the camera in response to an operation of the operating portion that starts photography in said camera; and
- a control portion that controls the changeable portion of the fluctuation detection device in response to a prediction by said predicting portion, so that the fluctuation detection device suppresses an influence of the shock fluctuation on generation of the output signal by the fluctuation detection device.
- 9. A camera according to claim 8, wherein the changeable portion generates an electromagnetic field.
