Abstract: An imaging device includes: an optical system which obtains an optical image of a photographic subject; an image sensor which converts the optical image to an electric signal; a digital signal processor which produces image data based on the electric signal; a display section which displays a photographic subject image expressed by the image data; and an operating section which performs a necessary setting regarding imaging, the digital signal processor including: an autofocus operation section which performs an autofocus operation based on data of an autofocus area set in the photographic subject image; a main area setting section which sets a main area in the photographic subject image; and a blurring operation section which performs a blurring operation on an area other than the main area in the photographic subject image, wherein the autofocus area is set automatically to overlap with at least a part of the main area.

Abstract: According to the present invention, when a lens is moved in an operation of an operation device, the focal information calculated for each travel position of the lens can be graphed corresponding to the lens position, and the focal information about the current lens position can be identified from the focal information about another position. Thus, a manual focus adjustment can be made while checking the graph. Especially, since the history of the focal information calculated for each lens travel position can be graphed, the lens can travel to the lens position in which a desired peak can be obtained when there are a plurality of peaks of focal information on the graph.

Abstract: A high resolution photographic system has a lens, a camera body, a bellows connecting the lens to the camera body, a ground glass designed for use with a microscope for focusing on the aerial image, a magazine configured to store a roll of film, wherein the magazine provides a pneumatic suction of a 9″×18″ frame of the film to a back of the magazine, two supports configured to connect to the camera body at a point coincident with the central horizontal axis of the negative allowing the camera body to tilt a user defined amount, a connection plate configured to connect each of the two supports, wherein the connection plate provides a swivel attachment for horizontal rotation of the camera body relative to the lens, a support rod attached to the connection plate, wherein the support has a bellows support and a front standard, a mirror alignment device, and a tripod which supports the rest of the photographic system.

Abstract: In a camera, a main body is provided with a rotating member, which is rotated along a guide of the main body, and the rotating member is connected with an operating device for rotating the rotating member. A focusing screen is mounted to the rotating member so as to correspond to a luminous flux section of a lens unit. A reflecting member for reflecting a subject image captured from the lens unit to a finder provided in the main body is mounted at a backside of the focusing screen in the rotating member. A case member containing an image pickup member corresponding to the luminous flux section of the lens unit is provided at the other side of the focusing screen via the reflecting member in the rotating member.

Abstract: A camera back having a frame for receiving a camera component and a locking arm pivotally connected to the frame. The locking arm includes an engagement surface for holding the camera component securely to the frame. The locking arm comprises a top and bottom locking member pivotally mounted to the frame with a handle connecting the top and bottom locking members. A biasing element urges the engagement surface against the frame in a downward position to securely hold the camera component in the frame. A tension device is attached to the frame so that after the camera component is locked into place on the camera back, the tension device effectively holds the locking arm in one position to avoid inadvertent unlocking.
