Patent attributes
A lens barrel includes: an image pickup optical system; an image pickup element; and a plurality of reflection members including first to n-th reflection members in order from the subject. The first reflection member is arranged at a position to bend an optical path of an incident light flux to enter the image pickup optical system. An (n−1)-th reflection member is arranged at a position to bend an optical path in a direction in a plane perpendicular to the optical path of the incident light flux. The n-th reflection member is arranged at a position closest to the image plane to bend an optical path in a direction parallel to the optical path of the incident light flux. The lens barrel further includes an actuator for moving the image pickup element in a plane perpendicular to an optical path bent by the n-th reflection member for stabilizing an image.
