Abstract: An imaging support method includes acquiring a focal length of an imaging apparatus, detecting a subject image position of a target subject image showing a target subject in a captured image obtained by capturing an imaging region including the target subject by the imaging apparatus, and performing registration control for setting the detected subject image position to a specific position in the captured image by increasing a ratio of application of an image region movement component compared to a lens moving mechanism in a case where the acquired focal length is greater than or equal to a threshold value, and increasing a ratio of application of the lens moving mechanism compared to the image region movement component in a case where the focal length is less than the threshold value.

Abstract: The lens holding frame is accommodated in the outer tube and is movable with respect to the outer tube in an optical axis direction (OAD) parallel to an optical axis of a lens optical system. The intermediate holding frame is a flexible frame body that constitutes the lens holding frame, is formed of a flexible material, and has a tubular shape. The intermediate holding frame is integrally provided with beam structures as abutments. The beam structures abut onto an inner circumferential surface of the outer tube in a state of being elastically deformed such that a restoring force is generated and prevent vibration caused by a gap between an outer circumferential surface of the lens holding frame and an inner circumferential surface of the outer tube.
