Claims
- 1. An image stabilizing device comprising:
- photographic lens means having a first lens unit movable along an optical axis of said photographic lens means and a second lens unit movable in a direction having a component transverse to the optical axis;
- first detection means for detecting the position of said first lens unit;
- second detection means for detecting a displacement of said photographic lens means;
- calculation means for calculating the amount of movement of said second lens unit on the basis of the detection result of said first and second detection means; and
- driving means for driving said second lens unit on the basis of the result of the calculations of said calculation means.
- 2. An image stabilizing device according to claim 1, wherein the lateral magnification of said first lens unit varies with movement along the optical axis and wherein said calculation means calculates the amount of movement of said second lens unit taking into consideration said variable lateral magnification.
- 3. An image stabilizing device according to claim 2, wherein said first lens unit is a lens unit for focusing.
- 4. An image stabilizing device according to claim 3, wherein said photographic lens means further comprises a front lens unit provided in front of said first lens unit.
- 5. An image stabilizing device according to claim 1, wherein said second lens unit is provided behind said first lens unit.
- 6. An image stabilizing device according to claim 5, wherein said second lens unit is provided at the rear end of said photographic lens means.
- 7. An image stabilizing device comprising:
- photographic lens means having a compensation mechanism for stabilizing an image of an object;
- focus detecting means for detecting the focusing condition of said photographic lens means in accordance with a photographing light flux of said photographic lens means;
- detection means for detecting a displacement of said photographic lens means;
- calculation means for calculating the amount said compensation mechanism is to be driven on the basis of the detection result of said detection means;
- driving means for driving said compensation mechanism on the basis of the calculation result of said calculation means during the operation of said focus detecting means; and
- a shutter unit which permits an exposure to be made by said photographic lens means at an imaging plane.
- 8. An image stabilizing device according to claim 7, wherein said photographic lens means further comprises a movable lens unit movable in a direction having a component transverse to an optical axis of said photographic lens means and wherein said compensation mechanism moves said movable lens unit.
- 9. An image stabilizing device according to claim 7, further comprising first switching means for outputting a first signal to said focus detecting means and second switching means for outputting a second signal to said shutter unit.
- 10. An image stabilizing device according to claim 9, wherein said photographic lens means further comprises a movable lens unit movable in a direction having a component transverse to an optical axis of said photographic lens means, and wherein said driving means drives said movable lens unit in response to said first or second signals.
- 11. An image stabilizing device comprising:
- photographic lens means having a compensation mechanism for stabilizing a vibrating image of an object;
- focus detecting means for detecting the focusing condition of said photographic lens means in accordance with a photographing light flux of said photographic lens means;
- detection means for detecting a displacement of said photographic lens means, the displacement being externally induced by shaking of said photographic lens means and causing image blur;
- calculation means for calculating the amount that said compensation mechanism is to be driven on the basis of the detection result of said detection means; and
- driving means for driving said compensation mechanism on the basis of the calculation result of said calculation means during the operation of said focus detecting means.
- 12. An image stabilizing apparatus comprising:
- objective lens means, including a focusing lens and an optical unit, for focusing an image and for stabilizing an image focused by said focusing lens;
- first detection means for detecting a position of said focusing lens;
- second detection means for detecting a displacement of said objective lens means induced by external shaking of said objective lens means and causing image blur; and
- determining means for determining a drive amount of said optical unit for stabilizing the image obtained by said objective lens means based on position information pertaining to said focusing lens and detection information obtained by said second detection means.
- 13. An image stabilizing apparatus according to claim 12, further comprising decentered means for decentering said optical unit relative to an optical axis of said objective lens, wherein said decentering means is responsive to an output of said determining means.
