Driving mechanism
A driving mechanism is provided, including a fixed portion, a movable portion, a driving assembly and a connecting element. The movable portion may move relative to the fixed portion and is used for holding an optical module. The driving assembly moves the movable portion relative to the fixed portion. The connecting element is movably connected to the fixed portion and the movable portion.
Lens driving apparatus, and camera module and optical device comprising same
A lens moving apparatus includes a housing, a bobbin disposed in the housing, a first coil disposed on the bobbin, a magnet configured to move the bobbin in a first direction parallel to an optical axis by an electromagnetic interaction with the first coil, an elastic member coupled to the bobbin, and a second coil disposed on the housing. A first portion of the second coil is coupled to the housing. The second coil generates an induction voltage resulting from an inductive interaction with the first coil when the bobbin moves in the first direction.
Lens driving device, and camera module and optical device including same
An embodiment comprises: a housing; a bobbin disposed in the housing; a coil disposed on the bobbin; a magnet disposed in a side portion of the housing, and including a first side surface facing the coil and a second side surface opposite to the first side surface; and a yoke disposed in the upper portion of the housing and overlapping the magnet in the optical axis direction, wherein: the centerline of the magnet is located on one side with reference to a reference line; a first groove adjoining one end of the first side surface of the magnet is disposed at a first end of the magnet; a second groove adjoining the other end of the first side surface of the magnet is disposed at a second end of the magnet; the reference line passes through the center of the housing and is perpendicular to the outer surface of the side portion of the housing where the magnet is disposed; and the centerline of the magnet is a straight line passing through the center between the first end and the second end of the magnet and perpendicular to the first side surface of the magnet.
CAMERA MODULE THAT PERFORMS IMAGE STABILIZATION
A camera module includes a lens assembly aligned along an optical axis, an optical image stabilization (OIS) carrier coupled to the lens assembly to move the lens assembly on a plane perpendicular to the optical axis, and a housing to accommodate the lens assembly and the OIS carrier. A first OIS magnet and a second OIS magnet are fixed to a first side surface of the OIS carrier, and are arranged side by side on the first side surface along a direction perpendicular to the optical axis. A first OIS coil member and a second OIS coil member face the first OIS magnet and the second OIS magnet, respectively. A first portion of the first OIS magnet is adjacent to the second OIS magnet and a second portion of the second OIS magnet is adjacent to the first OIS magnet.
OPTICAL DRIVING MECHANISM
An optical driving mechanism is provided. The optical driving mechanism includes a first movable part, a fixed part, and a first driving assembly. The first movable part is connected with an optical element. The first movable part is movable relative to the fixed part. The first driving assembly drives the first movable part to move relative to the fixed part. The fixing part has an opening.
Camera actuator, camera module, and camera mount device
A camera actuator comprises: a fixed-side member; a movable-side member disposed separated from the fixed-side member in a direction orthogonal to a light axis, the movable-side member holding a lens unit; a first lens drive actuator that displaces the movable-side member in at least a prescribed direction; an elastic support member that extends in the direction orthogonal to the light axis, and supports the movable-side member in relation to the fixed-side member so as to allow the displacement in at least the prescribed direction; and a gel-like first damping member provided to the elastic support member.
Camera with Folded Optics
Various embodiments include a camera with folded optics and lens shifting capabilities. In some examples, a folded optics arrangement of the camera may include one or more lens elements and one or more light path folding elements (e.g., a prism). Some embodiments include voice coil motor (VCM) actuator arrangements, carrier arrangements, and/or suspension arrangements to provide autofocus (AF) and/or optical image stabilization (OIS) movement. Furthermore, some embodiments include position sensor arrangements for position sensing with respect to AF and/or OIS movement.
DIGITAL DISPLAY WELDING MASK WITH HDR IMAGING
A display system for a welding helmet that includes a darkening filter layer, a high-dynamic range (HDR) camera system to capture an HDR light field, and an optical image stabilization subsystem. Captured images are displayed on an HDR electronic display within the welding helmet without risk of overexposure of ultraviolet radiation to the operator. In some examples, dual electronic displays are used to display different HDR images to each eye of the operator.
Electromagnetic driving mechanism and assembly method thereof
An electromagnetic driving mechanism is provided for driving two different optical lenses, including a base, a first holder, a frame, a resilient element, a first electromagnetic driving assembly, a second holder, and a second electromagnetic driving assembly. The first and second holders are provided for holding the optical lenses. The frame is affixed to the base, has magnetically permeable material, and surrounds the first holder. The resilient element connects the first holder with the frame. The first electromagnetic driving assembly is disposed between the first holder and the frame to drive the first holder moving relative to the base. The second electromagnetic driving assembly is disposed on an outer side of the second holder to drive the second holder moving relative to the base.
Camera module and optical device comprising same
A camera includes a lens barrel, a holder, a filter disposed in the holder, a circuit board having an aperture, a reinforcing member including a first region corresponding to the aperture and a second region in which the circuit board is disposed, and an image sensor disposed in the first region of the reinforcing member. The first region of the reinforcing member includes a protruding part protruding farther than the second region of the reinforcing member. The image sensor is disposed on the upper surface of the protruding part.
