摘要： An undesired signal contained in a signal related to blur suppression, e.g., an error output signal contained in a blur detection signal and obtained upon generation of a shock, is stored. When the state represented by the signal is determined without using the signal, and an undesired state is determined, e.g., when a state in which an error output signal is contained in a blur detection signal is predetermined from the state of a structure for generating a shock or impact, the signal related to blur suppression is accordingly synthesized with the stored undesired signal, e.g., the error output signal is subtracted from the blur detection signal, thereby forming a corrected signal for blur suppression, to perform a blur suppression operation in accordance with the corrected signal.

摘要： An interchangeable lens includes an image stabilizing unit, a position detector configured to detect a position of the correction lens, and a controller configured to set a movable range of the correction lens, when the interchangeable lens is mounted on a first camera body having a function of correcting at least one of a peripheral brightness and an aberration of a picked-up image according to position information of the correction lens, the controller sets the movable range of the correction lens to a first movable range, and when the interchangeable lens is mounted on a second camera body not having a function of correcting the peripheral brightness or the aberration of the picked-up image according to the position information of the correction lens, the controller sets the movable range of the correction lens to a second movable range that is narrower than the first movable range.

摘要： An optical apparatus includes a shake detection unit to detect shaking applied to a camera; an image blur correction driving unit for driving a lens and correcting image blur caused by the shaking; and a selection unit configured to select whether correction of image blur is to be permitted or inhibited. If image blur correction is permitted, the image blur correction driving unit operates in accordance with a first driving characteristic. If image blur correction is inhibited, the image blur correction driving unit holds the lens near an optical axis in accordance with a second driving characteristic.

摘要： An image blur prevention apparatus having a movable member (correction lens) which moves for preventing an image blur, or an apparatus applied to the image blur prevention apparatus includes the movable member, and an operation device which fluctuates at least one of the movable member and a contact member (a support member for movably supporting the correction lens) contacting the movable member against the other member within a fluctuation range in which the fluctuation does not appear as an image blur (with a fluctuation having an amplitude and frequency, in which the fluctuation does not appear as the image blur). With this arrangement, the frictional force between the movable member and the contact member is reduced (such that a dynamic frictional state is generated by a fluidizing effect), so that a proper operation of the movable member and a proper image blur prevention operation are enabled (smooth movement of the movable member is prevented from being impeded to generate a delay in response).
