Referring to FIG. 1, a virtual reality (VR) image rendering apparatus 100 according to an embodiment of the present invention may include a display unit 110, an image extracting unit 120, and a location setting unit 130. .

The display unit 110 may be three-dimensionally installed to display a game image implemented in virtual reality by a user. For example, the display 110 may display a user's play in a virtual reality space. In this case, the display unit 110 may display a screen for the user's viewpoint in the virtual reality space. However, the present invention is not limited thereto, and the display unit 110 may display screens for various viewpoints in the virtual reality space.

The display unit 110 may be separately installed in an actual real space. That is, the display unit 110 may be three-dimensionally installed in a space separate from the rest of the configuration of the VR image rendering apparatus 100 according to an embodiment of the present invention (for example, in the front or side of the user). .

Specifically, the display unit 110 may be formed of an LED screen. In addition, the display unit 110 may not only be composed of one screen, but may also include a plurality of screens. In this case, each of the plurality of screens may be arranged in different directions. In addition, a plurality of screens may be disposed on a ceiling and a floor at a location where the user is located. In this way, through the three-dimensionally installed display unit 110, an on-site audience or a viewer can more vividly view a user's play in a virtual reality space. The display unit 110 is not limited to an LED screen, and may be any configuration capable of displaying a game image to an audience, such as an LCD or OLED.

In addition, the display unit 110 may include a first display unit that displays a screen of the user's viewpoint in the virtual reality space and a second display unit that displays the entire screen of the virtual reality space. For example, a first display unit is placed on the player's seat playing a game in a virtual reality space, and a second display unit is placed in front of the stage so that the audience and viewers in the field can generally see how each user is playing in the virtual reality space. Can be placed. Accordingly, the audience and viewers in the field can view the video for both the viewpoint of the player playing the game and the overall viewpoint.

The image extracting unit 120 may extract a screen in the virtual reality space, convert the extracted screen to fit the installation state of the display unit 110 and transmit it to the display unit 110. In this case, there may be various methods of extracting the screen of the virtual reality space by the image extracting unit 120 and converting the screen to be displayed on the display unit 110.
