A holding member holds a lens and the holding member and the moving member are moved together in the optical axis direction by rotation of the shaft member. An urging member is arranged to urge the holding member and the moving member to move together in the optical axis direction and permits relative movement of the holding member and the moving member. A stopper is arranged to have the holding member to abut thereon when the holding member moves relative to the moving member against an urging force of the urging member.
Abstract: An illumination device (flash device), which is suited to cameras, includes a flash discharge tube, and an optical member having an entrance surface which a light beam from the flash discharge tube is made to enter and an exit surface from which the light beam having entered the entrance surface is made to exit, wherein a plurality of prism portions are arranged at the exit surface of the optical member, and wherein a part of the plurality of prism portions totally reflect a part of the light beam having entered the entrance surface. The totally-reflected light beam returns to the entrance surface or a reflector and is again reflected therefrom to be efficiently radiated toward the subject.
Abstract: An image display apparatus includes an image reading part for reading an image from an image recording medium, a position reading part for reading absolute-position information indicative of a position, from the image recording medium, a storage medium which stores a plurality of place-name data corresponding to the absolute-position information, and a display part for selecting and displaying particular place-name data corresponding to the absolute-position information.
Abstract: In a camera, an image correcting apparatus, an image correcting system, an image correcting method or a computer program product providing the image correcting method, an object image is recorded as a photo-taking image, and an object image obtained at a point of time different from a point of time at which the photo-taking image is obtained is recorded as a correction image to be used for correcting the photo-taking image.
Abstract: A video camera is provided with a processing circuit for processing a picked-up image signal outputted from an image sensor, a control circuit for controlling an image pickup action by transferring signals with the processing circuit, a serial communication circuit disposed between the control circuit and the processing circuit for controlling the transfer of signals between the control circuit and the processing circuit, and a change-over circuit for changing over an order of transmission of communication data within one unit to be transmitted by the serial communication circuit.
Abstract: A quantity-of-light adjusting device includes a drive source, a base member having an opening formed therein, and a blade arranged to move by being driven by the drive source and having three openings formed therein side by side in a row in a moving direction of the blade, wherein, among the three openings formed in the blade, the opening situated in the middle of the row is larger than the opening formed in the base member.

Abstract: An optical apparatus and a camera are provided, which have line-of-sight detecting means, and are capable of selecting a proper AF point selected even if the actually detected line of sight deviates significantly from the observer's intention and capable of reducing the time required for selecting the AF point. A plurality of focus detecting areas are provided on an observing screen, from which focus information on a subject is detected. A line-of-sight detecting device picks up an image of an eyeball of the user to detect the location of a gazing point of the user, A grouping circuit groups the focus detecting areas into a plurality of groups with priorities based on the detected location of the gazing point. A selecting circuit selects one of the groups according to the priorities and selects at least one focus detecting area from the selected group.
