The metal portion includes magnet fixing portions formed of a magnetic material and to which a driving magnet is fixed, and spherical body contact portions in contact with a spherical body made of metal and serving as a fulcrum for pivotal movement of the holder.
SYSTEMS, APPARATUS, AND METHODS FOR STABILIZATION AND BLENDING OF EXPOSURES
Systems, apparatus, and methods for stabilization and blending of exposures. So-called Electronic Image Stabilization (EIS) techniques use image manipulation software to compensate for camera motion. Unfortunately, existing EIS techniques cannot compensate for artifacts introduced by low shutter speed (e.g., blurs). Various embodiments of the present disclosure generate stabilized images from multiple exposures. In one exemplary embodiment, the stabilized exposures are blended using a linear sum of the color data for each pixel of the image. By stabilizing each exposure and linearly summing the light information, the camera shake can be removed, and the subject motion blur can be controlled. The stabilization and blending techniques enable a mathematical emulation of a selected shutter angle from many high-speed exposures.

A sensor shifting actuator includes a fixed body; a moving body disposed in the fixed body and including an image sensor having an imaging surface; a supporting substrate disposed in the fixed body and configured to support the moving body so that the moving body is movable with respect to the fixed body in first and second directions parallel to the imaging surface of the image sensor; and a driver configured to move the moving body in either one or both of the first and second directions. The supporting substrate includes a movable portion coupled to the moving body, a fixed portion coupled to the fixed body, and a connection portion disposed between the movable portion and the fixed portion. The movable portion and the connection portion are movable together in the first direction, and the movable portion is movable with respect to the connection portion in the second direction.
