摘要： An image-taking apparatus is disclosed which allows a selection of a type of image stabilization to be used from optical image stabilization and electronic image stabilization as required to provide an excellent output image. The image-taking apparatus has an image generator which is operable in a first mode in which it performs electronic image stabilization processing based on a plurality of images sequentially taken with an image-pickup device to generate an output image and a second mode in which it generates an output image without performing the electronic image stabilization processing on an image taken with the image-pickup device. The image-taking apparatus also has a controller which causes image stabilization operation to be performed through driving of an optical system in both of the first and second modes and selects one of the first mode and the second mode.

摘要： A clamping device for a camera accessory such as a hood includes a generally tubular attachment portion forming a part of the accessory for attachment to a camera lens mount or a pre-assembled, telescoping hood arranged on a lens mount. A number of projecting members extend radially inwardly from the inner circumference of the attachment portion to contact the outer periphery of the lens mount or pre-assembled hood. An engagement member extends through the attachment portion and is urged by a spring to contact the outer periphery of the lens mount or pre-assembled hood so that the engagement member, together with the projecting members, operate to fix the accessory on the lens mount or pre-assembled hood.

摘要： An extension tube or barrel which can be connected between a camera body and an interchangeable lens assembly includes a tubular body arranged to be coupled at one end to the camera body and at its other end to the lens assembly. A member within the tubular body is provided for engaging a diaphragm actuating member in the lens assembly in response to movement of an actuating member in the camera body. The extension tube also includes an arrangement for interchanging the positional relationship between the actuating member in the lens assembly and the member in the extension tube when the tubular body is either coupled to or uncoupled from the camera body. Thus, mechanical interference between the actuating member in the camera body and the corresponding member in the extension tube is avoided when the tubular body is placed against the lens mount of the camera and rotated during coupling or uncoupling of the extension tube.
