Image stabilizing apparatus and image pickup apparatus
The image stabilizing apparatus includes a base member, a first member shiftable with respect to the base member in a direction orthogonal to an optical axis direction, a first actuator shifting the first member with respect to the base member, an image-pickup element constituted by a photoelectrical conversion element, a second member holding the image-pickup element. The second member is shiftable together with the first member in the direction orthogonal to the optical axis direction and rotatable with respect to the first member in a plane orthogonal to the optical axis direction. The apparatus further includes a second actuator rotating the second member with respect to the first member.
