Claims53
An image stabilizing apparatus, comprising:
- image stabilization means for compensating image blur by moving in an optical path of the image stabilizing apparatus, said image stabilization means being movable in at least two different directions;
- and
- restriction means for restricting movement of said image stabilization means, wherein said restriction means becomes inoperable when a driving state of said image stabilization means does not satisfy a predetermined relationship of the two different directions, and becomes operable when the driving state satisfies said predetermined relationship, so that the driving state in said two different directions does not exceed the predetermined relationship.
A camera system, comprising:
- image stabilization means for compensating for image blur by moving in an optical path of the camera system, said image stabilization means being movable in at least two different directions;
- restriction means for restricting movement of said image stabilization means, wherein said restriction means becomes inoperable when a driving state of said image stabilization means in said two different directions does not satisfy a predetermined relationship and becomes operable when the driving state satisfies said predetermined relationship, so that the driving state in said two different directions does not exceed the predetermined relationship.
