Abstract:
1. A camera comprising: a camera body; a lens optical system having a plurality of lens elements; a lens moving device for moving at least one of said plurality of lens elements along an optical axis of said lens optical system, toward an object side to elongate a total length of said lens optical system in a lens protruding operation, or toward an image side to shorten the total length of said lens optical system in a lens collapsing operation; a shake detection device for detecting a shake of said camera; a movable device movable in a perpendicular plane to the optical axis of said lens optical system, said movable device being used for compensating for a deviation of an optical image formed through said lens optical system, the deviation resulting from the shake of said camera; a first control device for moving said movable device to an inserted position inserted in an optical path of said lens optical system with said lens protruding operation, or to a removed position out of said optical path with said lens collapsing operation; and a second control device that calculates an amount and direction of movement of said movable device necessary for canceling the deviation of said optical image when said shake detection device detects the shake, said second control device causing said movable device to move by said calculated amount in said calculated direction; wherein the first control device is connected to the camera body and the second control device is connected to the first control device or the camera body, wherein said movable device compensating for the deviation constitutes a component of said lens optical system in said inserted position and said second control device comprises a linear displacing device for displacing said movable device linearly in a radial direction to a circular direction about a pivotal point that is located outside said lens optical system.
