Claims
- 1. An image-shake correcting device comprising:
- detecting means for detecting a vibration;
- correcting means for correcting a motion of an image due to the detected vibration;
- limiting means for limiting a response of said correcting means to an output of said detecting means;
- switching means for switching between an operating state and a non-operating state of said correcting means; and
- control means for temporarily shifting a cut off frequency of a frequency response characteristic of said limiting means to a higher side in response to said correcting means being switched from the non-operating state to the operating state by said switching means.
- 2. A device according to claim 1, wherein said correcting means includes a variable angle prism.
- 3. A device according to claim 1, wherein said detecting means includes a vibration gyro sensor.
- 4. A device according to claim 1, wherein said detecting means includes an angular velocity sensor.
- 5. An image-shake correcting device comprising:
- detecting means for detecting a vibration;
- correcting means for correcting a motion of an im a ge due to the detected vibration;
- limiting means for limiting a response of said correcting means to an output of said detecting means;
- switching means for switching a operating state and a non-operating state of said correcting means;
- means for temporarily shifting a cut off frequency of a frequency response characteristic of said limiting means to a higher side in response to said correcting means being switched from the operating state to the non-operating state by said switching means; and
- control means for controlling said correcting means according to said switching means.
- 6. An image-shake correcting device according to claim 5, wherein said means for changing increases a cutoff frequency of said limiting means up to a predetermined value when said correcting means is switched from the non-operating state to the operating state by said switching means, and then gradually decreases the cutoff frequency to a steady value.
- 7. An image-shake correcting device according to claim 5, wherein said means for changing increases a cutoff frequency of said limiting means on a step-by-step basis when said correcting means is switched from the operating state to the non-operating state by said switching means, and returns the cutoff frequency to a steady value after said correcting means is stopped.
- 8. An image-shake correcting device according to claim 5, wherein said control means includes position detecting means for detecting a driving position of said correcting means based on an output of said limiting means, and wherein said control means confirms through said position detecting means a return of said correcting means to a central position after an initial variation of the characteristic of said limiting means by the means for changing and brings said correcting means to the non-operating state.
- 9. An image-shake correcting device according to claim 5, wherein said control means includes position detecting means for detecting a driving position of said correcting means based on an output of said limiting means.
- 10. An image-shake correcting device according to claim 5, wherein said control means includes position detecting means for detecting a driving position of said correcting means from an.
- 11. An image-shake correcting device according to claim 5, wherein said control means includes position detecting means for detecting a driving position of said correcting means on the basis of an output from said limiting means.
- 12. An image stabilizing apparatus comprising:
- detecting means for detecting a motion of an image;
- correcting means for correcting the detected motion;
- processing means for computing control information for driving said correcting means to correct the motion of the image;
- selecting means for selecting between a power-on state and a power-off state of said correcting means; and
- control means for temporarily shifting a cut off frequency of a frequency characteristic of a system comprising said detecting means, said correcting means, and said computing means, to a higher side in response to a selecting operation by said selecting means.
- 13. Apparatus according to claim 12, wherein said control means changes the response of the system in response to switching the correcting means from the non-operating state to the operating state.
- 14. Apparatus according to claim 13, wherein said control means resets the change of the response after a predetermined time has passed since the switching operation.
- 15. Apparatus according to claim 12 or 14, wherein the response comprises a frequency response characteristic.
- 16. Apparatus according to claim 12, wherein said detecting means includes an angular velocity sensor, and wherein said correcting means includes a variable angle prism.
