摘要： A camera shake compensation device for a photo-taking optical system includes a shake compensation optical element having an optical axis; a first holding member that holds the shake compensation optical element; a drive source that drives the first holding member in order to cause the shake compensation optical element to move such that the optical axis of the shake compensation optical element becomes eccentric with respect to an optical axis of the photo-taking optical system; and a second holding member that holds the first holding member by means of the drive source so that the second holding element can move along a photo-taking optical axis together with the first holding member and drive source during focusing or zooming by the photo-taking optical system.

摘要： A camera having an image shift detecting function is provided with an optical system which forms a subject image, an image sensing device which converts light of the subject image into an electric signal, an image shift detecting sensor which detects a relative shift between the camera and the subject image based on an output of the image sensing device and a microcomputer which compensates for the relative shift between the camera and the subject image based on an image shift amount detected by the image shift detecting sensor. The microcomputer specifies an area of the image sensing device based on a direction of luminance variation of the subject image and the image shift detection is made by using only an output corresponding to the specified area.

摘要： An apparatus has a member to be driven, an actuator for driving the member, a position detector and a controller. The actuator drives the member to move by an amount proportional to a given number of pulses. The position detector detects a position of the member in predetermined detection steps. The controller determines in steps smaller than the predetermined detection steps a target position up to which the member is to be moved. Then, it controls the actuator up to a detection-step position before the target position by closed-loop control in accordance with a detection result from the detector. Further, it controls the actuator from the detection step position to the target position by open-loop control.

摘要： A lens system for compensating for shaking movement of a camera includes an objective lens system that forms the image and a compensating lens system interposed in the optical axis of the objective lens system. The compensating lens elements are driven by electro-mechanical transducers, which provides a compact system permitting a relatively small lens construction. A driving shaft is frictionally coupled to a support for the compensating lens elements and is attached to an electro-mechanical transducer, for example, a piezoelectric element that expands and contracts responsive to a pulse wave. A movement detector monitors the objective lens system and calculates an amount of shaking compensation needed, which is provided to a pulse generator.
