Abstract: This invention provides a lens device and a correction method therefor whereby the focal position of the lens device can be corrected with high accuracy even if a lens surface shape or the like is not uniform. A ring-shaped lens fixing frame 52 is mounted on the outer periphery of a lens 51. A gear 53 is formed on the lens fixing frame 52 in the circumferential direction. A gear 54, which engages with the gear 53, is rotated by a motor 20A. Then, the lens 51 rotates about the optical axis L thereof. Further, a rack 57, which extends in the direction of the optical axis L, is formed on a part of the lens fixing frame 52. A pinion 58 engages with the teeth 57A of the rack 57, and the pinion 58 is rotated by another motor 20B. Then, the rack 57 moves in the direction of the optical axis L, and thus the lens 51 moves in the direction of the optical axis L. Since the lens 51 rotates about the optical axis L thereof, even if the surface shape or the like of the lens 51 is uneven in the circumferential direction, improvement can be realized.

Abstract: Provided are an imaging controller, an operation method and program of the imaging controller, and a camera capable of presenting a radiation image of a subject to a user in an easy-to-understand manner. An image sensor driving control unit causes an image sensor to image a visible ray to acquire a first image including a reflected image of a subject. The image sensor driving control unit causes the image sensor to image an infrared ray to acquire a second image including the reflected image and a radiation image of the subject. A zoom lens driving control unit moves a zoom lens along an optical axis to correct a difference in angle of view between the first image and the second image. Image processing units output difference images between the first image and the second image acquired in a state in which the difference in angle of view is corrected.
