An international exhibition for broadcasting professionals is underway near Tokyo. About 1,000 companies are taking part in Inter BEE.
This year, many are showcasing systems that integrate artificial intelligence and virtual-reality technologies with cameras and other conventional equipment.
One system by a maker of 8K ultra-high-definition cameras uses AI to recognize a person's face and automatically follow them.
One possible application of the technology is the use of a single camera to track each member of large musical groups during TV performances.
NHK was one of the event's participants.
Its booth features a system that can link the movement of a camera in a studio with CG-generated scenery on a screen. The system can seamlessly combine images of the real world with the virtual background.
NHK is also introducing a virtual-reality version of Hiroshima's Atomic Bomb Dome. It was created with photographs taken by a 360-degree camera.
Visitors wear a head-mounted display to view the dome's interior, where tourists are normally barred from entering.
Inter BEE ends on Friday.
