An apparatus and method are provided. The apparatus includes an imaging device; a stage movable relative to the imaging device; an isolation plate provided between the imaging device and the stage, including a horizontal glass plate; and a plurality of interferometers in electronic communication with a processor. The plurality of interferometers include three interferometers disposed on the imaging device, configured to direct a first beam set in a first direction toward the horizontal glass plate; and three interferometers disposed on the stage, configured to direct a second beam set in a second direction toward the horizontal glass plate, the second direction being opposite to the first direction. The processor is configured to measure distances between the imaging device and the isolation plate and distances between the stage and the isolation plate based on the first beam set and the second beam set reflected from the horizontal glass plate.

In a vehicle camera device, engaging claws of a base are passed through through-holes of a camera mechanism and insertion pins of a second cover are inserted in insertion holes that are within the engaging claws, such that the through-holes are positioned with respect to the engaging claws and the insertion pins are positioned with respect to the insertion holes. Therefore, the camera mechanism and the second cover can be positioned with respect to the base, and a lens of the camera mechanism and an opening of the second cover can be aligned well.

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). A clamp groove (21) is provided on the external peripheral wall of the lens (2). The clamp part (32) is engaged in the clamp groove (21) of the lens (2) along the guide groove (12). The camera module structure is convenient to assemble, and compared with screw connection, adhesive connection and other modes, problems such as vibration, falling-off and fracture would not happen, the imaging quality is good, and the service life is long.

Systems and devices for controlling camera privacy in wearable devices are described. A camera cover can be provided that is movable between a closed position and an open position. In the closed position, the camera cover can occlude a field of view of a camera, such that the camera cannot capture meaningful data. In the open position, the camera cover can be at least partially out of the field of view of the camera, such that the camera can capture meaningful data. The camera cover can be positioned within a housing of the wearable device, and an actuator can be positioned external to the housing of the wearable device. A user can move the camera cover by moving the actuator.

A camera casing having at least one front face. The at least one front face has a first opening, the front face being configured to securely fit with a camera, a flexible covering attached to a perimeter of the front face and the flexible covering having a service opening to provide access to an interior of the camera casing. A first retaining member may be incorporated into the flexible covering and configured to secure the camera to the front face; the front face is a rigid or a semi-rigid material; the front face has one or more 3D features to correspond to one or more features of the camera for positioning the camera within the camera casing; or combinations thereof.

A compact first-person-view (FPV) pan and tilt camera mount is installed in a remote-controlled vehicle, and the vehicle is configured to accommodate a video processing module/air unit, a camera module, and a horizontal and vertical rotatable (pan and tilt) camera mount module. A realistic scale remote-controlled scale vehicle typically comes with interior cabin or cockpit space to accommodate driver/pilot that can be utilized to install the pan & tilt camera module. The video processing module is configured to process images shot by the camera module. The camera is mounted on the pan and tilt module. The pan and tilt module includes a first servo, a base, a movable seat, a rotation module, a clamp portion, and an accommodation portion. The first servo has a first shaft, the movable seat has a fitting seat, and the fitting seat has a connection orifice. The rotation module has a first semi-circular gear and a second semi-circular gear meshing. The accommodation portion is formed on the movable seat and is configured to receive a second servo, and the second servo has a second shaft.

In a first communication mode, a control unit controls a signal level of one contact based on a first command received from an imaging apparatus via another contact and a signal level indicated by an accessory device via yet another contact. In a second communication mode, the control unit receives a second command indicating the second communication mode and data via another contact. After the reception, the control unit transmits the data via still another contact. The control unit controls communication in the second communication mode based on the signal level of the one contact and the second command.
