An optical unit includes a movable body including an optical element, a support body swingably supporting the movable body, and a suction mechanism. The optical element reflects light traveling in a first direction to an intersecting second direction. The suction mechanism generates suction force in the movable body between the movable body and the support body, and includes a magnet and a magnetic member. One of the magnet and the magnetic member is in the movable body, while the other is in the support body. The magnet and the magnetic member overlap each other when viewed from a predetermined direction, which is one of the first direction, the second direction, and a third direction. The third direction intersects the first and second directions. When viewed from the predetermined direction, a center of the magnet and a center of the magnetic member are separated from each other.

There are provided a reflecting module for optical image stabilization (OIS) and a camera module including the same. The reflecting module for OIS includes: a housing including an internal space; a movable holder supported in the internal space of the housing by an elastic member; a reflecting member disposed on the movable holder; and a driving part configured to provide driving force to the movable holder so that the movable holder is moved relative to the housing, wherein the elastic member includes a fixed frame fixed to the housing, a movable frame provided in the fixed frame, and a spring connecting the fixed frame and the movable frame to each other and, the movable frame is movable in relation to two axes perpendicular to each other.

A light irradiation device includes a light source, a projection optical system, wedge prisms, and an aberration correction surface. The projection optical system projects an image formed based on light emitted from the light source. The aberration correction surface corrects an aberration occurring when the image is projected by the projection optical system. The wedge prism deflects the light emitted from the projection optical system. The wedge prism deflects the light deflected by the wedge prism. The wedge prisms are held so that a deflection direction of light emitted from the wedge prism is changed by rotation of at least one of the wedge prisms. The aberration correction surface is on the wedge prism side with respect to an emission surface of the projection optical system, and is located on the projection optical system side, with respect to the wedge prism, including an incidence surface of the wedge prism.

An apparatus for driving an optical system with a memory unit includes a main frame having an optical system; a base frame configured to accommodate the main frame; a driving unit configured to move the main frame in a first direction perpendicular to an optical axis with respect to the base frame; and a memory unit configured to store first reference position information that is information about a position at which the optical system is aligned in the first direction.

An optical arrangement includes a stack structure comprising at least three prisms. The optical arrangement includes a main optical path and for each of the prisms, a secondary optical path. The optical arrangement also includes at least one interface. Each of the at least one interface is arranged between a corresponding first stack section of the stack structure and a corresponding second stack section of the stack structure. Each of the at least one interface is configured to enable relative movement of the corresponding first stack section and of the corresponding second stack section with respect to one another.

According to an aspect of the present disclosure, an optical member driving device is provided. The device includes a fixed portion, a pivoting portion with a holding portion for holding the optical member, a pivot shaft, a driving portion, and a pivot suppressing portion. The pivot suppressing portion has a first magnet at the pivoting portion, and a second magnet at the fixed portion. The first magnet and the second magnet are disposed in such a manner that the same magnetic poles face each other in the pivoting direction.

Methods and apparatus for maintaining, adjusting and/or accurately determining the position of a moveable element, e.g., a moveable shaft mounted component are described. The moveable component may be, for example, a mirror or mirror support of a camera module. A hall sensor is used to measure distance to the moveable component. To facilitate the distance measurement a magnet is secured to the moveable component. The hall sensor is used to determine the distance between the magnet and sensor. A metal plate is placed along a side of one of the supports used to support the shaft to which the moveable component is attached. The magnet which facilitates distance measurement is attracted to the plate reducing the risk of side to side movement even when the shaft fits loosely in the supports and is rotated. The magnet facilitates distance measurements and reliable control of position relative to the sidewall plate.

A present disclosure relates to a prism apparatus, a camera apparatus and an image display apparatus including same. The prism apparatus according to one embodiment of the present disclosure includes a prism holder for fixing a prism to a first surface; a yoke of which a first surface is attached to a second surface of the prism holder which is rear surface of the first surface of the prism holder; a drive magnet attached to a second surface of the yoke which is rear surface of the first surface of the yoke; a sensor magnet disposed above the yoke; a hall sensor spaced apart from the sensor magnet; and a sensor magnet supporter to which the sensor magnet is attached. Accordingly, the magnetic field is detected accurately.

Systems and methods for correcting point of view (POV) aberrations in scanning folded cameras and multi-cameras including such scanning folded cameras. In a Tele folded camera that includes an optical path folding element (OPFE) and an image sensor, the OPFE is tilted in one or two directions to direct the Tele folded camera towards a POV of a scene, a Tele image or a stream of Tele images is captured from the POV, the Tele image having POV aberrations and the POV aberrations are digitally corrected to obtain an aberration-corrected image or stream of images.

The embodiment relates to an image stabilization device and a camera module including the same. The image stabilization device according to the embodiment includes: a first prism for changing a path of a light beam; a second prism disposed below the first prism and changing a path of light beam emitted from the first prism; an image stabilization control unit for controlling a shape of the second prism including a coil part and a magnet part. The first prism may be disposed inside the image stabilization control unit. The second prism may be a variable wedge prism. The image stabilization control unit may control the path of the light beam by changing the shape of the second prism through the magnet part.
