Provided are a camera assembly and a method of installing the camera assembly. The camera assembly includes: a base portion; a guide rail mounted on a surface of the base portion; a magnet arranged to face the guide rail; a camera lens units arranged to be moveable on or along the guide rail; and a cover configured to fix positions of the camera lens units to the guide rail by pushing at least one of the plurality of camera lens units.

The present invention provides a photographing synchronization method for performing a synchronous photographing operation on a plurality of cameras using any one of cameras in a multi-camera system. The method comprises: obtaining all cameras in a current synchronous network by means of network broadcast; obtaining signal transmission delays between the cameras; generating a synchronous photographing instruction of each camera according to the signal transmission delays between the cameras; and sending the synchronous photographing instructions to particular cameras over a wireless network.

Systems and methods are presented herein that facilitate temporally synchronizing, in real time, a separately sourced high quality audio segment of a live event with a video segment that is generated by a recording device associated with a member of the audience. An A-V Synchronization Application may synchronize a video segment of a live event that is generated from a personal electronic device of an audience member with a high quality audio segment that is separately sourced and generated by professional sound recording equipment at the live event. The result of the temporal synchronization is a high fidelity digital audio visual recording of the live event. In various, the audience member may stream, in real-time, the high fidelity digital audio visual recording to an additional electronic device at a different geo-location. In some examples, narrative audio segments may be also included as part of the high fidelity digital audio visual recording.

A control device includes a data storing unit, a synchronization control unit, a light emission control unit, and a luminance adjustment unit. The light emission control unit derives a luminance adjustment parameter for adjusting a light emission luminance of light emitting elements when a video image is displayed with a total number of vertical lines in a current frame such that a total light emission amount of the light emitting elements during one frame period when the video image is displayed with the total number of vertical lines in the current frame is equal to a total light emission amount of the light emitting elements during one frame period when a video image is displayed with a pre-set minimum number of vertical lines. The luminance adjustment unit adjusts, based on the luminance adjustment parameter, the light emission luminance of the light emitting elements.
