An optical assembly of an imaging device includes an array of lens assemblies each having a double-folded optical axis, and an image sensor. Each of the lens assemblies each having the double-folded optical axis includes an input optical axis folding element, at least one lens having an optical power, and an output optical axis folding element. The input optical axis folding element of each of the lens assemblies having the double-folded optical axis is configured to change a field of view (FOV) of the input optical axis folding element by changing an optical axis folding angle of the input optical axis folding element about two axes.

An optical element drive device includes a movable section and a fixed section. The movable section includes a first magnetic field generator for generating a first magnetic field and is drivable in a motion direction. The fixed section includes a sensor unit. The sensor unit carries out a detection based on the first magnetic field and a bias magnetic field different from the first magnetic field.

Protection system for an optical sensor in a motor vehicle and for detecting an environment of the motor vehicle is provided, wherein the protection system comprises at least one cover for the optical sensor, which can be brought into a cover position in which the optical sensor is protected from environmental influences by the at least one cover. The protection system comprises a storage device for a plurality of covers, from which at least one cover can be moved into the cover position.

The present disclosure provides an optical unit with shake correction function capable of preventing a thrust receiving member, which fixes a sphere, from falling off from the movable body in an optical axis direction. According to some embodiments of the present disclosure, a thrust receiving member to which a first sphere is fixed is held by a holding portion formed of the cutout recess provided in a fixed body. A bottom wall surface of the holding portion makes contact with a bent plate portion of the thrust receiving member from −Z direction side. Further, locked surface parts provided on a pair of side wall surfaces of a holding portion make contact, from +Z direction side, with a pair of locking plate portions protruding from a bent plate portion in circumferential direction in the thrust receiving member.

A camera, camera lens, image sensor, and a shape memory alloy (SMA) motor are stacked within a frame. The SMA motor is located on an out-light side of the camera lens. The image sensor is located between the lens and the SMA motor and is fastened to the SMA motor. The SMA motor is configured to actuate the image sensor to shift on a plane perpendicular to an optical axis of the camera lens. The camera may be associated with an electronic device.

A driving-unit operation method includes: generating pulse blocks on the basis of driving pulses; and modifying a driving signal in accordance with a position error signal. In the modifying the driving signal, when the position error signal is in a first range, the shape of the driving pulses is modified so as to form a first driving-pulse shape, and the pulse-block duty cycle is set to a first pulse-block duty cycle value, whereas when the position error signal is in a second range, the shape of the driving pulses is modified so as to form a second driving-pulse shape, and the pulse-block duty cycle is set to a second pulse-block duty cycle value.

This lens drive device is provided with: a first movable part; a second movable part; a first drive part; and a second drive part. The first drive part and the second drive part respectively have a first ultrasonic motor and a second ultrasonic motor. The first ultrasonic motor and the second ultrasonic motor are arranged on sides opposite to each other with respect an optical axis, and independently drive the first movable part and the second movable part in the optical axis direction.

A camera module structure, comprising: an upper housing (1) and a lens (2). The upper housing (1) comprises an accommodating part (11); the lens (2) is mounted in the accommodating part (11). The structure further comprises a circlip (3). The circlip (3) comprises a press part (31) and a clamp part (32). A guide groove (12) is provided on the upper housing (1).
