A lens control system and a method for compensating a disturbance force acting on a lens group of an optical assembly are provided. The optical assembly includes an actuator configured to move the lens group along an optical axis in response to an optical lens position command received from the camera controller. The lens control system further includes an optical assembly controller with a power driver configured to apply an electrical energy to the actuator to produce a force that acts on the lens group to move the lens group to a commanded position, a current sensor configured to measure a current flowing through the actuator in response to the electrical energy applied to the at least one actuator, and a position sensor configured to generate position information by measuring an actual position of the lens group.

An optical element driving mechanism includes a fixed portion, a movable portion, a driving assembly, and a limiting assembly. The movable portion is connected to an optical element with an optical axis, and is movable relative to the fixed portion. The driving assembly drives the movable portion to move relative to the fixed portion. The limiting assembly is disposed on the movable portion and is connected with the driving assembly. The driving assembly is limited to move within a movable range relative to the fixed portion by the limiting assembly.

Systems and methods are provided for a viewing headset usable with a display device. In one example, the viewing headset includes a headset lens frame with a lens frame body that has a lens positioned therein and a front panel coupled to the lens frame body via a hinge, the hinge permitting rotation of the front panel within a predetermined angular range. The headset lens frame further includes a display attachment device coupled to the lens frame body and the front panel, the display attachment device configured to removably secure a display device to the front panel.

A lens holder driving apparatus includes a fixed member; a lens holder configured to hold a lens body; a shaft member provided on the fixed member and extending along an optical axis direction so as to guide the lens holder; a piezoelectric driver including a piezoelectric element and configured to move the lens holder along the optical axis direction by a movement of the piezoelectric element; a receiving member provided on the lens holder; and a preload member provided on the fixed member. The piezoelectric driver is provided on the fixed member. The receiving member is disposed facing the piezoelectric driver so as to contact the piezoelectric driver, and receives the movement of the piezoelectric element. The piezoelectric driver includes a contact member and is configured to be preloaded toward the receiving member by the preload member such that the receiving member contacts the contact member.

Embodiments provide a lens moving apparatus including a bobbin having a lens barrel, a housing configured to accommodate the bobbin, an upper elastic member coupled to the bobbin and the housing, a lower elastic member coupled to the bobbin and the housing, a first coil disposed on the bobbin, a first magnet disposed on the housing, a circuit board disposed below the housing, a second coil disposed on the circuit board, a first sensor to output a first output signal based on a sensed result of a magnetic field strength of the first magnet, a first capacitor connected in parallel to the first sensor.

A camera lens suspension assembly includes a support member including a support metal base layer, a moving member including a moving metal base layer, bearings and smart memory alloy wires. The support member includes a bearing plate portion, static wire attach structures, and mount regions. A printed circuit on the support metal base layer includes traces extending to each static wire attach structure. The moving member includes a moving plate portion, elongated flexure arms extending from a periphery of the moving plate portion and including mount regions on ends opposite the moving plate portion, and moving wire attach structures. The bearings are between and engage the bearing plate portion of the support member and the moving plate portion of the moving member. Each of the smart memory alloy wires is attached to and extends one of the static wire attach structures and one of the moving wire attach structures.

Provided herein is an image focusing adjustment method, system, and module. A first image of a reference object is received in response to an input signal when the image focusing adjustment module is operating in a first state. The first image of the reference object is analyzed, based on which a plurality of adjustments to the image focusing adjustment module is controlled. The plurality of adjustments, performed by a plurality of actuators controlled by control module, include rotating a lens barrel assembly relative to a neck member along a first axis that causes a translational adjustment of the lens barrel assembly, rotating the neck member relative to a top member around the first axis that causes a rotational adjustment of the lens barrel assembly, and positioning a tilt adjustment member that causes tilt adjustment of the top member relative to a frame member along a second axis.

A terminal device includes: a housing; a screen arranged on the housing; a first lens arranged in the housing and disposed on a back of the screen; and a turnover module arranged on the hack of the screen in the housing and configured to change an orientation of the first lens, so that the first lens faces towards a first direction or a second direction of the screen, the second direction being different from the first direction.
