Indeed, it is just the single lens camera, so like Kodak SP360 4K, there will be a 120deg dark corner comparing to Ricoh Theta S, or Samsung Gear360. I think our difference is that we take the advantage of 240 fisheye lens view angle, so when we do the image drwarping, we could according to each frame's gyro/g-sensor to compensate the image roll/yaw/pitch. That will make the video keep stable when movement.
I just have two videos which I did the field test of our 1st version algorithm,"hiking in the rain". Here are the video links for your reference,(both of them are 360 video, you cold scroll it around and see that)

At that time our image quality is still not fine tuned and the weather is quite bad...... but you could compare the two videos.
And we are still improving our algorithm and trying to make the video more stable, I will try to make some videos for you later this week and let you see our improvement! :)
