1. An in-game 360 virtual reality (VR) image acquisition apparatus using a plurality of virtual cameras, the apparatus comprising:
a virtual camera group configured to take in-game images by using the plurality of virtual cameras;
a renderer configured to generate textures for the taken images, generate a panoramic image by performing an equirectangular projection (ERP) mapping of the generated textures, and encode the generated panoramic image; and
an image generator configured to generate a 360 VR image by combining audio information with the encoded panoramic image, and further configured to video-stream the generated 360 VR image and output the video-streamed 360 VR image to an outside of the apparatus,
wherein in the virtual camera group, omni-direction from a reference point for taking the images is divided into N (N is a natural number greater than 4), and a pair of left and right virtual cameras are arranged in each of N directions.
