LENS BARREL, IMAGE-CAPTURING DEVICE, AND METHOD FOR CONTROLLING LENS BARREL

摘要

A lens barrel in which tilt adjustment can be made depending on the position of a lens unit in the optical axis direction. This lens barrel includes: at least three guide bars provided so as to extend along the optical axis direction; a driving unit that respectively drives the at least three guide bars in the optical axis direction; a lens frame holding unit that holds an image-capturing lens, the lens frame holding unit being attached to at least three guide bars and being driven in the optical axis direction by the at least three guide bars; and a control unit that controls said at least three linear actuators so as to adjust the respective drive amounts in the optical axis direction of the at least three guide bars and to tilt the lens frame holding unit from a direction orthogonal to the optical axis.

1. A lens barrel comprising:
a first lens; a second lens different from the first lens; and a driving unit, which moves at least one of the first lens and the second lens in an optical axis direction, and which changes a tilt of the second lens in relation to the optical axis direction, based on a position of at least one of the first lens and the second lens in the optical axis direction.
