Video processing device and video generating system for virtual reality

A video processing device for virtual reality, comprising:

• a video input mechanism configured to receive a first original video and a second original video obtained from a first camera device;
• a video processing mechanism in transmission connecting to the video input mechanism, the video processing mechanism comprises a first video processing unit configured to adjust the first original video and the second original video to a first video and a second video, both the first video and the second video having a 2:1 aspect ratio, the first video processing unit is further configured to segment the second video from a short side of the second video to generate two first sub videos having a same aspect ratio, and segment the first sub videos from a long side of one of the first sub videos to generate three second sub videos having a same aspect ratio, to combine the first video and the second video into a third video having a 16:9 aspect ratio, wherein the third video comprises the first video, the non-segmented first sub video and the three second sub videos, and a short side of the third video is formed by a short side of the first video and a short side of the non-segmented first sub video, and the other short side of the third video is formed by three short sides of the three second sub videos;
• and
• a video output mechanism in transmission connecting to the video processing mechanism, and the video output mechanism is configured to output the third video through a physical wire.
