Claims
- 1. A blur correction apparatus of camera, comprising:
- a photographing optical axis system having a plurality of shutter blades;
- a blur correction optical system, positioned coaxially with respect to an optical axis of said photographing optical system, and movable in a plane normal to the optical axis;
- means for moving said blur correction optical system to keep an optical image, formed on a focal plane, stationary with respect to said focal plane; and
- means for manually selecting an activation and deactivation condition of said means for moving, said deactivation condition being one of a termination of movement of a trailing blade of said plurality of shutter blades and a photometering switch being turned off,
- whereby a user can confirm operation of said means for moving at least after an exposure sequence when said deactivation condition is said photometering switch being turned off.
- 2. The blur correction apparatus of claim 1, wherein said blur correction optical system is positioned between said photographing optical system and said focal plane.
- 3. The blur correction apparatus of claim 1, wherein said moving means comprises two motors having output shafts extending substantially perpendicular to each other.
- 4. The blur correction apparatus of claim 1, wherein said selecting means comprises a manually-operable switch.
- 5. The blur correction apparatus of claim 1, wherein said selecting means comprises two manually-operable switches, one of said two manually-operable switches selecting said activation condition, and the other of said two manually-operable switches selecting said deactivation condition of said plurality of deactivating conditions.
- 6. The blur correction apparatus of claim 1, wherein said camera comprises an SLR camera.
- 7. A blur correction apparatus of a camera, comprising:
- a photographing optical system having a plurality of shutter blades;
- a blur correction optical system, positioned coaxially with respect to an optical axis of said photographing system, and movable in a plane normal to the optical axis;
- means for moving said blur correction optical system to keep an optical image, formed on a focal plane, stationary with respect to said focal plane;
- means for activating said means for moving responsive to a first condition, said first condition being one of a commencement of movement of a leading one of said plurality of shutter blades and a time prior to said commencement;
- means for deactivating said means for moving responsive to a second condition, said second condition being one of a termination of movement of a trailing blade of said plurality of shutter blades and a time after said termination of said movement; and
- means for manually selecting said first and second conditions,
- whereby a user can confirm operation of said means for moving at least after an exposure sequence when said second condition is said time after termination of said movement.
- 8. The blur correction apparatus of claim 7, wherein said blur correction optical system is positioned between said photograph and optical system and said focal plane.
- 9. The blur correction apparatus of claim 7, wherein said means for moving includes first and second motors having substantially perpendicular shafts.
- 10. The blur correction apparatus of claim 7, wherein said first condition further comprises a photometering switch being activated, and said second condition further comprises said photometering switch being deactivated.
- 11. A blur correction apparatus of a camera, comprising:
- a photographing optical system having a plurality of shutter blades;
- a blur correction optical system, positioned coaxially with respect to an optical axis of said photographing optical system, and movable in a plane normal to the optical axis;
- means for moving said blur correction optical system to keep an optical image, formed on a focal plane, stationary with respect to said focal plane;
- said means for moving having at least first, second and third selectable modes of operation;
- said first mode of operation comprising activating said means for moving at a time prior to a commencement of movement of a leading one of said plurality of shutter blades, and deactivating said means for moving responsive to a termination of movement of a trailing blade of said plurality of shutter blades;
- said second mode of operation comprising activating said means for moving responsive to a photometering switch being activated, and deactivating said means for moving responsive to a termination of movement of a trailing blade of said plurality of shutter blades, whereby a user can confirm operation of blur correction at least prior to movement of said plurality of shutter blades; and
- said third mode of operation comprising activating said means for moving responsive to a release switch being activated, and deactivating said means for moving responsive to said photometering switch being deactivated, whereby a user can confirm operation of blur correction at least following exposure.
- 12. The blur correction apparatus of claim 11, wherein said plurality of modes includes a fourth mode of operation which activates and deactivates said means for moving responsive to said photometering switch being activated and deactivated, respectively, whereby a user can confirm operation of blur correction following exposure.
