A camera is configured for use with a removable camera lens cover, which can be secured to or removed from the camera by a user without the use of a tool set. The mechanism which allows the lens cover to be secured to and removed from the camera includes a set of wires embedded into the lens cover and a set of wedges protruding from the lens wall of the camera. To secure the lens cover to the camera, the lens cover is placed onto the front of the camera and rotated until the wires align with corresponding wedges, securing the wires underneath the tapered surface of the wedges. To remove the lens cover from the camera, a force is applied outward and normal to the lens cover, causing the wires to flex outward and enabling the rotation and removal of the lens cover from the camera.

A gimbal handle includes an enclosure including an accommodation space, a main control board accommodated in the accommodation space, and an electrical contact member provided at the main control board and electrically connected to the main control board. The electrical contact member penetrates the enclosure to expose to an outside of the enclosure. The electrical contact member is configured to be electrically connected to an adapter.

A lens unit and a camera module in which the electrical wiring extending from the electrically functional component in the lens barrel can be guided to the image side without interfering with an assembly operation, without the need of ensuring a wiring space in the lens barrel, and without forming an elongated through hole in the lens barrel. The lens barrel includes: i) a first through hole extending in the longitudinal direction inside the side wall to guide the electric wiring from the component to the image side end of the flange; ii) a second through hole extending radially on the side wall so the first through hole can communicate with the outside of the barrel; iii) an accommodation groove on the outer peripheral surface of the side wall to communicate with the second through hole, in order to accommodate the wiring and guide the wiring to the image side.

A detection device includes a substrate, a light source, a detection module, and a heat dissipation module. The substrate includes a first base plate, a second base plate, and at least one connecting portion connecting the first base plate to the second base plate. The light source is disposed on the first base plate. The detection module is disposed on the second base plate. The first base plate has a first surface towards the at least one connecting portion, and the at least one connecting portion has a second surface towards the first base plate. The second surface is connected to a portion of the first surface. The heat dissipation module is disposed on the at least one connecting portion and/or the second base plate, and the influence of heat on proper operation of the detection device is thus prevented.

An optical assembly (13) for a three-dimensional measurement device is equipped with: an optical lens (320) that forms a pair of conjugate planes having an optically conjugate relationship; an optical device (341) that is disposed on one of the pair of conjugate planes; a temperature sensor (354) for detecting the temperature of the optical lens (320); a heater (350) for heating the optical lens (320); and a control part that controls the operation of the heater (350) on the basis of the result of the detection made by the temperature sensor (354) such that the optical lens (320) reaches a constant temperature.

An image sensor includes an imaging device, an optical system including a liquid lens, a temperature sensor that detects a temperature of the liquid lens, a heater that heats the liquid lens, a temperature adjuster that controls the heater to adjust the temperature of the liquid lens to a predetermined temperature, a nonvolatile memory storing property information about the liquid lens, a refractive power controller that determines, based on a target refractive power and the property information stored in the nonvolatile memory, an application voltage applicable to the liquid lens adjusted to have the predetermined temperature and applies the application voltage to the liquid lens to control a refractive power of the liquid lens to match the target refractive power, and an image processor. The optical system, the nonvolatile memory, and the temperature sensor are disconnectable from a body module including the refractive power controller and the image processor.

A camera with a low maintenance burden is provided. A camera (1) includes a housing (2) having an opening (21), a lens (3) accommodated in the housing (2) to collect light entering through the opening (21), a shutter (4) that opens and closes the opening (21), and a contact member (5) attached to an inner surface of the shutter (4) to come in contact with the lens (3). The contact member (5) comprises a magnetic material and is attracted to the shutter (4) with a magnetic force from the magnetic material.
