Abstract

The present disclosure discloses a virtual cinema and an implementation method thereof. The implementation method of the virtual cinema comprises: arranging a virtual screen, and playing a video content thereon; and projecting ambient light varying with the video content around the virtual screen. By projecting ambient light varying with the video content around the virtual screen while displaying the video content to the user through the virtual screen, the sense of reality is enhanced, thereby solving the problem that the user experience is affected because the ambient light is not considered enough in the existed virtual cinema.

Claims

1. An implementation method of a virtual cinema, the implementation method comprising:

arranging a virtual screen;

playing video content on the virtual screen;

obtaining data of each frame of image of the video content in real time when the video content is playing on the virtual screen;

obtaining ambient light data corresponding to the obtained data of each frame of image in real time; and

projecting ambient light that varies with the video content around the virtual screen according to the obtained ambient light data.

3. The implementation method of a virtual cinema according to claim 1, wherein obtaining ambient light data comprises performing a Gaussian blur algorithm to process the data of each frame of image into data including only colors, which serves as the ambient light data.

4. The implementation method of a virtual cinema according to claim 3, wherein arranging the virtual screen includes arranging the virtual screen using a Unity3D technique or an OpenGL technique.

5. The implementation method of a virtual cinema according to claim 4, wherein the method is applicable to a virtual reality device, an enhanced reality device and an ordinary video player.

2. (canceled)

6. A virtual cinema, comprising a virtual screen, an ambient light obtaining module, and a projection module, the virtual screen configured to play a video content, the ambient light obtaining module connected to the virtual screen and the projection module, the ambient light obtaining module configured to obtain data of each frame of image played by the virtual screen in real time, obtain ambient light data corresponding to the obtained data of each frame of image in real time, and transmit the obtained ambient light data to the projection module, and the projection module configured to project ambient light that varies with the video content around the virtual screen according to the obtained ambient light data.

8. The virtual cinema according to claim 6, wherein the ambient light obtaining module is configured to perform a Gaussian blur algorithm to process the data of each frame of image into data including only colors, which serves as the ambient light data.

9. The virtual cinema according to claim 8, wherein the virtual cinema is configured to implement the virtual screen and the projection module using a Unity3D technique or an OpenGL technique.

10. A device including the virtual cinema according to claim 9, wherein the device includes one of a virtual reality device, an enhanced reality device and an ordinary video player.
