Hi, that was a fairly big error on my side in the original translation. It looks like two camera modules are being controlled by a single Raspberry Pi.
The questions that comes to mind is how did they do this and can a single Raspberry Pi control more than 2 camera modules?
It looks to me that there’s only a single USB cable going from the camera board and the Raspberry Pi. It also appears that there’s a ribbon cable from the control board to the Raspberry Pi.
Quite an interesting piece of gear. I’d like to see it in person. Unfortunately, that demo was in Tokyo, but I am hoping Ricoh will demo it in Santa Clara at an IoT conference so I can go down and look at it.
