A stage apparatus includes a stationary support plate; a stage member provided on the stationary support plate so as to move on a reference plane parallel with the stationary support plate; Y-direction magnetic flux generating devices secured to one of the stationary support plate and the stage member; and Y-direction moving coils secured to the other of the stationary support plate and the stage member, the Y-direction moving coils receiving magnetic flux from the Y-direction magnetic flux generating devices so as to generate a driving force in a specific Y-direction between the Y-direction magnetic flux generating devices and the Y-direction moving coils. The Y-direction moving coils are secured to the stage member so that the Y-direction moving coils at least partly overlap each other in an X-direction, which is parallel with the reference plane and perpendicular to the Y-direction, and do not overlap in the Y-direction.

An anti-shake apparatus of a photographing apparatus comprises a hand-shake quantity detector and a controller. The hand-shake quantity detector has a first detector having an angular velocity sensor and has a second detector having an angular displacement sensor. The controller performs an anti-shake operation based on a first angular signal from the first detector and a second angular signal from the second detector.

An anti-shake apparatus for image stabilization of a photographing apparatus comprises an imaging sensor, an acceleration sensor, and an inclination degree output unit. The imaging sensor has an imaging surface on which an optical image through a photographing optical system of the photographing apparatus is captured. The acceleration sensor detects a first gravitational acceleration component in a direction of a first detection axis and a second gravitational acceleration component in a direction of a second detection axis. The first detection axis and the second detection axis are perpendicular to an optical axis of the photographing optical system. The inclination degree output unit outputs information regarding an inclination angle caused by a roll of the photographing apparatus about the optical axis, based on the first gravitational acceleration component and the second gravitational acceleration component.

A digital camera comprises a solid state imaging device provided with an optical low-pass filter. A photographing optical system forms an object image on a light receiving surface of a CCD through the optical low-pass filter. An electronic-charge accumulation-time control program is stored in a ROM of a system control circuit to determine optimum exposure parameters according to which a photography is performed. The electronic-charge accumulation-time control program has a program diagram showing a relationship between an electronic-charge accumulation-time and an aperture value and/or an ISO speed.

An apparatus is provided for preventing an image from being blurred as it is being recorded on the film of a camera. Angular velocity sensors are provided for detecting the angular velocity applied to the camera, and an actuator is provided for actuating a shutter of the camera to correct for the movement of the camera when the absolute value of the angular velocity detected by the angular velocity sensors is below a predetermined value.

An exchangeable lens photographic camera of automatic focussing type capable of focussing objects between a minimum and an infinite focussing distance. The camera has an exchangeable lens exchangeable in the camera body. The lens has a first switch providing a signal associated with focussing an object at the infinite distance, and a second switch providing a signal associated with focussing an object at the minimum distance. A focussing motor is coupled to the lens for moving the lens for focussing objects lying between the minimum and infinite distances. A first pair of contacts coupled between the exchangeable lens and the camera body transmits therebetween signals indicating the presence and direction of rotation of the focussing motor. A second pair of contacts, coupled between the exchangeable lens and the camera body, transmits the signals produced by the first and second switches from the exchangeable lens to the camera body. The first and second pairs of contacts are oriented on the exchangeable lens relative to each other for providing signal coupling between the exchangeable lens and the camera body.

An imaging unit to be inserted into a camera body from a predetermined direction, thus to constitute a digital camera in combination with the camera body, is provided. The imaging unit is provided with an image pickup unit including an imaging device that obtains an object image, an imaging device driver that drives the imaging device, an image processor that processes an output signal of the imaging device; a casing for accommodating the image pickup unit, the imaging device driver and the image processor, and a lid attached to the casing so as to slide between a closed position where the lid covers a receiving surface of the image pickup unit, and an open position where the lid does not cover the receiving surface of the image pickup unit. In this structure, the lid is moved to the open position by a force exerted for inserting the imaging unit into the camera body.

A stage apparatus includes a stationary support member, a movable stage plate supported by the stationary support member to be movable in a plane relative to the stationary support member, at least one magnetic force generator which is provided integral with the stationary support member, and at least one coil which is mounted on the movable stage plate and receives a magnetic force generated by the magnetic force generator to produce a driving force for driving the movable stage plate in the plane. At least one hole in which the coil is fixedly fitted is formed on the movable stage plate.
