Abstract
An apparatus for correcting a blurred image has a blurred image correcting lens which constitutes at least part of a photographing lens of a camera. The correcting lens is supported to move in a direction substantially perpendicular to an optical axis of the photographing lens. A driver for driving the correcting lens and an angular acceleration sensor which detects the angular acceleration applied to the camera, to send a drive signal to the driver, to cancel an undesirable movement of the optical axis of the photgraphing lens are provided. The angular acceleration sensor includes a rotatable sensor arm having a rotational shaft in the center of the length of the sensor arm, permanent magnets provided at the opposite ends of the sensor arm, a magnetic sensor which is opposed to one of the permanent magnets, and a coil which is opposed to the other permanent magnet and which has a winding intersecting the magnetic flux of the other permanent magnet. The blurred image correcting lens is driven in accordance with the output of the coil.
