An apparatus includes a first correction unit including a first movable unit and a first mechanism configured to lock a position of the first movable unit. An interchangeable lens including a second correction unit is attachable to and detachable from the apparatus, and the second correction unit includes a second movable unit and a second mechanism configured to lock a position of the second movable unit. The apparatus further includes a control unit configured to, when the interchangeable lens is attached to the apparatus and one of the first and second movable units is fixed by the first or second mechanism, move the position of the other movable unit in a direction that cancels a shift of an optical axis caused by the fixation of the one of the first and second movable units.

A lens apparatus is provided with movable first and second units, first and second holders for holding the first and second units, a driving unit for electrically driving the second holder, a transmission member movable relative to the second holder in the optical axis direction and transmits driving force to the second holder, a biasing member for biasing the second holder toward the first holder side relative to the transmission member, a controller for controlling the driving unit, and first and second detectors for detecting the positions of the first and second holders, wherein movable ranges of the first and second holders have interference region which interfere with each other, and controller changes a control of driving unit between the interference region where the first and the second holding members interfere each other and an interference-free region based on detection results of the first and second detectors.

A lens driving device includes a first housing; a bobbin disposed in the first housing; an aperture disposed on the bobbin; a board disposed on the first housing; a second coil and a fourth coil disposed on the board; a second magnet disposed on the bobbin and facing the second coil; a fourth magnet disposed on the aperture and facing the fourth coil; and a fourth sensor disposed on the board and configured to sense the fourth magnet. The fourth coil is overlapped with the second coil in a first direction perpendicular to an optical axis direction.

A camera body with which it is possible to improve the effect of shake correction, a camera accessory, and an information transmission method wherein the camera body to which a camera accessory can be detachably mounted, and includes: a movable section which is movable to correct shaking of the camera body; a detection unit which detects the shake and outputs a detection signal; a calculation unit which, on the basis of the detection signal, calculates an amount of movement of the movable section; and a transmission unit which transmits, to the camera accessory, body-side information the calculation unit uses to calculate the amount of movement.

An electronic device includes a lens assembly that receives external light, which is used by a camera module to capture a still image and/or a moving picture, in a first direction, a housing forming an outer portion of the camera module, a first support disposed inside the housing and disposed in a second direction away from the lens assembly, wherein the second direction is perpendicular to the first direction; and a second support including at least a portion protruding in the second direction while surrounding the lens assembly, wherein the first support and the second support are disposed in the second direction away from the lens assembly.

A camera system may include one or more voice coil motor (VCM) actuators to implement focus, tilt and shift functions. The VCM actuators may include coils segmented into multiple coil segments having individually impedances lower than the impedance of the respective coil as a whole. The coil segments may be individually driven by respective currents at different points in time to interact with magnet(s) to produce motive forces along the same axis. Based on the winding configuration and driving mode of the coil segments, the motive forces may move a lens group relative to an image sensor in a direction substantially orthogonal to an image plane, tilt the lens group relative to the image sensor, or shift the image sensor relative to the lens group on the image plane.

An optical element driving mechanism is provided, including a fixed part, a movable part and a driving assembly. The fixed part has a main axis, includes an outer frame and a base. The outer frame has a top surface and a sidewall. The top surface intersects the main axis. The sidewall extends from the edge of the top surface along the main axis. The base includes a base plate intersecting the main axis and securely connected to the outer frame. The movable part moves relative to the fixed part, and connects to an optical element having an optical axis. The driving assembly drives the movable part to move relative to the fixed part. The main axis is not parallel to the optical axis.
