One embodiment of a lens driving apparatus may comprise: a bobbin having a first coil disposed on the outer circumferential surface thereof; a position detection sensor which is disposed on the outer circumferential surface of the bobbin and which moves together with the bobbin; a first magnet disposed opposite to the first coil; a housing for supporting the first magnet; upper and lower elastic members which are coupled to the bobbin and the housing; and a plurality of wirings which are disposed on the outer circumferential surface of the bobbin so as to electrically connect at least one of the upper or lower elastic members with the position detection sensor.

A lens barrel that achieves modes with and without an optical element while reducing a size in an optical axis direction. A first drive mechanism moves a first optical element in the optical axis direction. A second optical element is located at an image surface side of the first optical element and is selectively inserted in an optical path. A second drive mechanism moves a holding member that holds the second optical element in a direction different from an optical axis. A control unit controls the first drive mechanism to move the first optical element to an object side to a position where the first optical element and the holding member are not in an overlap state when viewing in a direction perpendicular to the optical axis, controls the second drive mechanism to remove the second optical element from the optical path, when they are in the overlap state.

An imaging element incorporates a reading portion that reads out captured image data at a first frame rate, a storage portion that stores the image data, a processing portion that processes the image data, and an output portion that outputs the processed image data at a second frame rate lower than the first frame rate. The reading portion reads out the image data of each of a plurality of frames in parallel. The storage portion stores, in parallel, each image data read out in parallel by the reading portion. The processing portion performs generation processing of generating output image data of one frame using the image data of each of the plurality of frames stored in the storage portion.

The technology of this application relates to an actuating device, a camera module, and an electronic device. In the actuating device, an actuator is configured to include an actuating magnetic component, a power supply apparatus, and at least one coil. The power supply apparatus is electrically connected to the coil, and the coil is disposed in a magnetic field of the actuating magnetic component. When a current is supplied to the coil, the coil or the actuating magnetic component moves under an action of the magnetic field. In this case, the coil or the actuating magnetic component can drive a motor carrier to move, to drive a lens of the camera module to move, so that zooming of the camera module is completed.
