The present invention relates to a camera apparatus, and more particularly, to a magnetic levitation camera apparatus and a live video system therewith.
A traditional camera or camcorder apparatus used for image and/or audio/video capture is typically powered by bulky batteries or thick power cables, and may sometimes be set above mounting stands. Such setup limits the movement of the apparatus and also reduces the operator's freedom in positioning said apparatus. As energy-storage technologies evolve to reduce battery sizes and phase out thick power cables, said apparatus have become smaller in size and lighter in weight, making them easier to operate. However, they may still be fixed to mounting stands and cannot move freely. Cameras being fixed to mounting stands also increase their overall visual size, making them physically and visually unattractive. To indicate their operational status, the cameras usually use blinking lights and/or visual prompts on their display screens to suggest data transmission and/or recording. However, blinking lights may not be clearly visible from a distance.
Webcams are cameras connected to a computer that enables the user to transmit the captured images or to stream audio/video information to a remote location. Such internet-enabled devices tend to have limited functionality, in that they typically transmit the information to be stored remotely and do not have local storage. Such cameras also typically consist of a single front-facing lens, allowing only audio/video information of objects directly in front of the camera body to be captured. In such configuration, all objects to be captured would need to be placed in front of the camera, leading to yet again limited placement or positioning of the camera apparatus.
The present invention provides a magnetic levitation camera apparatus and a live video system therewith for solving above drawbacks.

In one embodiment of the present invention, the application software 4001 of the remote electronic device 4000 is operated to transmit a command, wherein the command is submitted to the external router 2000 that in turn transmits the command to the camera module 2 and the base module 1 (step S01). Subsequently, the image capturing unit 21 of the camera module 2 is turned on for capturing images or recording videos based on the command (step S102) ; meanwhile, one of the first magnetic component 11 and the second magnetic component 22 is electrified to repel the other one of the first magnetic component 11 and the second magnetic component 22 based on the command, thereby levitating the camera module 2 from the base module 1 (step S103); at the same time, the camera communication unit 24 receives information from the remote electronic device 4000 via the external router 2000 (step S104).
Upon completion of step S102, the processing unit 23 controls the camera communication unit 24 to transmit the captured images or the captured videos to the remote electronic device 4000 via the external router 2000, and/or to transmit the images or the videos to the data storage server 3000 via the camera communication unit 24 (step S106); simultaneously, the processing unit 23 stores the images or the videos captured by the image capturing unit 21 in the data storage unit 25 (step S107).
In another embodiment of the present invention, the processing unit 23 processes the captured images or the videos to determine whether an object shown in the images or the videos is a human character or not . The processing unit 23 can further determine the number of human characters shown in the images or the videos, and/or can further determine whether an object shown in the images or the videos is moving. The processing unit 23 then controls the camera communication unit 24 to transmit a processing result of the images or the videos (e.g. , a result on the number of human characters determined from the images or the videos, or a result of whether the characters in the images or the videos are moving) to the remote electronic device 4000 via the external router 2000, the transfer of processing results being an alternative to step S106 shown in

In one embodiment of the present invention, the magnetic levitation camera apparatus 1000 is operated during a meeting or a conference call, but an application of the present invention is not limited thereto. When the application software 4001 of the remote electronic device 4000 is operable to transmit a command to the magnetic levitation camera apparatus 1000, a link between the magnetic levitation camera apparatus 1000 and the remote electronic device 4000 is established. The camera module 2 levitates from the base module 1 to indicate that remote users are ready to participate in the meeting or the conference call. The images or videos captured by the image capturing unit 21 are transmitted to the remote electronic device 4000 via the external router 2000 for viewing on the remote electronic device 4000. Conversely, when remote users leave the meeting or the conference call, the application software 4001 is operable to transmit a command to the magnetic levitation camera apparatus 1000 terminating the link between the magnetic levitation camera apparatus 1000 and the remote electronic device 4000, stops the transmission of the captured images or videos, and subsequently docking the camera module 2. Therefore, the presence of remote users during the meeting or conference call is suggested by the status (levitating or non-levitating) of the camera module 2.
Additionally, the image capturing units 21 are configured in a 360-degree arrangement surrounding the perimeter of the camera module 2. This allows images and/or videos surrounding the entirety of the camera module 2 to be captured while reducing blind spots in the captured images and/or videos; configuring the camera module 2 with a panoramic camera can further reduce said blind spots.

In one embodiment of the present invention, the magnetic levitation camera apparatus 1000 is mounted with a plurality of image capturing units 21 capable of capturing multiple images and/or videos simultaneously. The application software 4001 on the remote electronic device 4000 can be configured to display multiple images and/or videos that are captured by their respective image capturing units 21 in multiple view windows (400a, 400b, 400c, 400d, 400e, 400f) . The application software 4001 can alternately be configured to display single images and/or videos in a single view window (400e).
In one embodiment of the present invention, the images and/or videos captured by the image capturing units 21 are transmitted in real-time (streamed) to the remote electronic device 4000. Remote users can select a single view window to be displayed in the application software 4001, so as to avoid a delay in data transmission, as transmitting images and/or video from multiple image capturing units 21 may increase the burden on data servers and reduce the quality of the transmitted images and/or videos.
It can be seen from the aforementioned embodiments that the present invention includes the following advantages:
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention. Accordingly, the above disclosure should be construed as limited only by the metes and bounds of the appended claims.
