"Multi-viewpoint Robot Camera System" that cooperatively controls nine cameras to follow the subject

Images taken from various angles of the subject are called "multi-view images", but in NHK, nine robot cameras cooperatively control so that they face one subject, and multi-view shooting is possible even for moving subjects We developed a system. By doing this, you can see the player in the dribbling not only from the side but also from the surroundings, or you can make the stereoscopic image seen in the integral stereoscopic television.

The robot camera is placed on a cooperatively controlled pan head.


This cameraman coordinates and controls nine cameras so that the subject comes to the center.


By this, it is possible to make a picture of 'Gurutto vision' that can see the athlete's appearance all the time.
