Abstract
An image vibration reduction apparatus comprises a correction lens, a first moving member having a lens frame that holds the correction lens, a second moving member having an aperture portion in which the lens frame is slidably fitted, a first actuator that drives the first moving member, a second actuator that drives the second moving member, and a holding member that supports the first moving member and the second moving member. Driving direction of the first actuator and the second actuator is oriented in a first direction that is perpendicular to the optical axis of the correction lens, and a second direction in which the second actuator displaces the lens frame via the second moving member is perpendicular to the first direction.
