Abstract
A lens barrel comprises a vibration detecting device for detecting a vibration, a correcting optical device for correcting the vibration on the basis of an output of the vibration detecting device, and a diaphragm unit having a variable aperture diameter, and the vibration detecting device is disposed in a plane which is approximately flush with a driving part for the diaphragm unit and perpendicular to an optical axis, or the vibration detecting device is formed on or integrally with a lens barrel portion which holds an optical member other than the correcting optical device.
Claims18
A lens barrel comprising:
- a plurality of optical elements;
- vibration detecting means for detecting a vibration of said lens barrel;
- correcting means for correcting a vibration of an image due to the vibration, on the basis of an output of said vibration detecting means;
- and
- a diaphragm unit having a variable aperture diameter,
- said vibration detecting means being disposed in a plane approximately flush with a driving portion of said diaphragm unit and perpendicular to an optical axis of said lens barrel.
A lens barrel comprising:
- a plurality of optical elements;
- vibration detecting means for detecting a vibration of said lens barrel;
- correcting means for correcting a vibration of an image due to the vibration, on the basis of an output of said vibration detecting means;
- a diaphragm unit having a variable aperture diameter;
- and
- holding means for holding said vibration detecting means, said holding means having a shield part for preventing disturbance of said vibration detecting means,
- said holding means and said diaphragm unit being provided integrally with each other.
A lens barrel comprising:
- vibration detecting means for detecting a vibration of said lens barrel;
- correcting means for correcting a vibration of an image due to the vibration, on the basis of an output of said vibration detecting means;
- first holding means for holding said vibration detecting means, said holding means having a shield part for preventing disturbance of said vibration detecting means;
- and
- second holding means for holding a lens element,
- said first and second holding means being formed integrally with each other.
A lens barrel comprising:
- vibration detecting means for detecting a vibration of said lens barrel;
- correcting means for correcting a vibration of an image due to the vibration, on the basis of an output of said vibration detecting means;
- and
- a lens holder for holding a lens element,
- said vibration detecting means being provided on said lens holder.
A lens barrel comprising:
- vibration detecting means for detecting a vibration of said lens barrel;
- correcting means for correcting a vibration of an image due to the vibration, on the basis of an output of said vibration detecting means, said correcting means having a movable optical element;
- and
- holding means for holding an optical element other than said movable optical element,
- said vibration detecting means being disposed on said holding means.
