A dual camera module that includes a voice coil motor actuator and a method for controlling the same are disclosed. The dual camera module comprises a first camera including a first lens module; a second camera including a second lens module, arranged to adjoin the first camera; and a controller for controlling the first camera and the second camera, wherein the controller identifies whether the first camera includes a first sensing module for sensing movement of the first lens module if a camera execution command is received, identifies whether the second camera includes a second sensing module for sensing movement of the second lens module if the first camera includes the first sensing module, identifies whether the first sensing module of the first camera and the second sensing module of the second camera have the same type as each other if the second camera includes the second sensing module, and controls the first camera and the second camera at different time zones if the first sensing module and the second sensing module have the same types as each other.

Provided are a detecting unit that detects that a light-shielding member has passed a predetermined position at the time of the light-shielding member moving to a closed state and to an opened state, and a control unit that changes at least one of a driving start timing at the time of driving a stepping motor and a driving speed at the time of driving the stepping motor, based on the detection results of the detecting unit.

An optical image stabilizer is provided, in which magnets and coils are arranged such that they oppose each other. The Hall sensors are arranged such that one face of each is opposed to one face of the magnets, respectively. The Hall sensors can detect the location of a group of lenses by generating a corresponding signal in response to a variation in magnetic force following a variation in the gap between magnets depending on the direction in which a group of lenses is driven, and simultaneously, in response to a variation in magnetic force that occurs when the group of lenses is displaced in the direction that intersects the direction of the gap.

The imaging device includes: at least one imaging unit configured to be rotatable with a driving mechanism and movable in a circumferential direction; an illumination; a cover configured to cover the imaging unit and the illumination; and a light-shielding member of which at least a part is disposed between the imaging unit and the illumination and is disposed in contact with the cover. The light-shielding member is able to be retracted away from the cover through driving of the driving mechanism.

A driving mechanism is provided, including a fixed portion, a movable portion, a driving assembly and a buffering element. The movable portion is movably connected to the fixed portion for holding an optical element having a main axis. The driving assembly is disposed in the fixed portion for moving the movable portion relative to the fixed portion. The buffering element is disposed between the movable portion and the fixed portion, wherein a stopping assembly is disposed on the fixed portion and/or the movable portion to limit the range of motion of the movable portion relative to the fixed portion, the buffering element is not in contact with the movable portion or the fixed portion when the movable portion is static, and the hardness of the buffering element is less than the hardness of the stopping assembly.

A position detecting apparatus includes a rotating member rotatable and having a first cam and a second cam, a first detector, a second detector, and a rotational position acquirer. The first cam moves the first moving unit in a first rotational range of the rotating member and a second rotational range following the first rotational range. The second cam moves the second moving unit in the second rotational range of the rotating member and a third rotational range following the second rotational range. The rotational position acquirer acquires the rotational position using the first signal in the first rotational range and in part on a first rotational range side in the second rotational range, and acquires the rotational position using the second signal in the third rotational range and in part on a third rotational range side in the second rotational range.

Various embodiments include a camera with image sensor shifting capabilities and a flexure arrangement. In various embodiments, the flexure arrangement may include an upper flexure and a lower flexure. The upper flexure may include a suspension wire that extends between two sheets. The lower flexure may include one or more flexure arms that connect a moveable platform to a stationary platform.

A follow focus enabling a user to move quickly move into and out of a hard stop operation. A soft stop orientation provides haptic feedback at manually calibrated focusing settings.

Provided is a lens driver movable in a direction parallel to an optical axis, arranged on a lens driver movable in a plane orthogonal to the optical axis, and accommodated in a casing. The lens driver includes: a fixture base, a support frame A, a lens module, a spring piece, a first driving coil, a magnet and a yoke. The lens driver includes: a base; a connection terminal and a conductive member A arranged on the base; a support frame B supported by a support part; a conductive member B arranged on the support frame; a center holding part for keeping the base and the support frame B at a center of the optical axis; a second driving coil arranged on the base; and a magnetic detecting element. The lens driver provided can achieve purposes of anti-image dithering and simplifying assembly to obtain good image quality.

One embodiment of a lens module includes a first lens including a fluid so as to absorb incident light; and a second lens forming an interface with a part of the first lens, the second lens including a fluid so as to permit passage of the incident light therethrough, wherein the second lens defines a first optic path in a center part thereof to permit passage of the incident light therethrough, and the first light path is changed in a cross-sectional area as the interface varies, and wherein a second optical path is formed at a portion of the first lens that is located adjacent to the first optical path.
