ABSTRACT:
This apparatus includes a lens element (2) associated with first guide means (6, 7) defining a first degree of freedom of this lens element (2) in a plane parallel to the film plane. These first guide means (6, 7) are associated in turn with second guide means (11, 12) defining a second means [sic] of freedom, via a ring (10) parallel to the plane of the lens element (2). These second guide means (11, 12) are hinged to parts (14) that are structurally connected to the body of the camera. Accelerometers (20, 21, 22, 28, 29, 30) measure the acceleration along the two degrees of freedom, and their signals serve to control motors (16, 23) that act via cams (27, 24) on the first and second guide means, respectively, to compensate for the movements recorded by the accelerometers.
