A driving mechanism for supporting an optical member is provided, including a fixed module, a movable module, a driving module disposed therebetween, and an elastic member. The driving module can drive the movable module to rotate around a first rotation axis relative to the fixed module. The elastic member includes a first connecting portion connected to the movable module, a second connecting portion connected to the fixed module, a first string portion connected to the first connecting portion, and a first buffer portion connected to the first string portion. The first string portion is disposed on the first rotation axis. The longitudinal axis of the first string portion is parallel to the first rotation axis. The first buffer portion has wave-shaped structure.

A reflecting module for optical image stabilization (OIS) includes a housing; a rotation holder provided in the housing and comprising a reflecting member; a rotation plate provided in the housing between an inner wall of the housing and the rotation holder so that the rotation holder is supported by the inner wall of the housing via the rotation plate; and a driving part configured to apply a driving force to the rotation holder to move the rotation holder.

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.

An image stabilization lens module includes a lens holder, a light-folding element, a movable carrier, a fixed base, a swing element and a driving mechanism. The movable carrier carries the light-folding element. The fixed base connects the movable carrier via an elastic element. The swing element between the movable carrier and the fixed base includes a main body, a carrier support structure and a base auxiliary structure on a carrier corresponsive surface of the main body, and a base support structure and a carrier auxiliary structure on a base corresponsive surface of the main body. The carrier support structure supports the movable carrier. The base support structure contacts the fixed base. The driving mechanism is for driving the movable carrier to rotate. The carrier auxiliary structure, the base auxiliary structure and the main body are formed in one piece.

A prism apparatus, and a camera and an image display apparatus including the same are disclosed. The prism apparatus includes: a first prism configured to reflect input light toward a first reflected direction, a first actuator configured to change an angle of the first prism about a first rotation axis to change the first reflected direction based on a first control signal, a second prism configured to reflect the light reflected from the first prism toward a second reflected direction, and a second actuator configured to change an angle of the second prism about a second rotation axis to change the second reflected direction based on a second control signal.

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.

Various embodiments include a camera with a voice coil motor (VCM) actuator assembly to provide autofocus (AF) and/or optical image stabilization (OIS) movement. The VCM actuator assembly is configured to move an image sensor of the camera in three dimensions (e.g. X, Y, and Z) to provide the AF and/or OIS movements. The VCM actuator assembly is asymmetrical and includes an at least partially open side that allows an optical assembly of the camera to pass through the open side of the VCM actuator. In some embodiments, the optical assembly is part of a folded optics arrangement of the camera that includes one or more prisms/and or lenses.

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.

The present invention relates to a prism module, a camera comprising same, and an image display device. A prism module, according to one embodiment of the present invention, comprises: a prism holder having a prism fixed to a first surface thereof; a yoke coupled to a second surface of the prism holder; a driving magnet seated on the yoke; a sensor magnet disposed on the yoke; a hall sensor disposed to be spaced apart from the sensor magnet; and a sensor magnet support member to which the sensor magnet is attached. Thereby, it is possible to precisely detect a magnetic field.
