I echo everyone's positive comments, he is a true genius and I congratulate him for his success in building that Iconoscope camera and making it work really really good!!!
I am glad to have found that video on YouTube just typing in iconoscope and checking the latest video uploads, good thing it was titled in English as well as Japanese otherwise I would of never found it.
Anyhow I've made a picture collage of stills from that video and a 3" image orthicon video (Eisenhower dedication to WRC-TV 1958) and a video I made from my 1974 Sony AVC-3250CE 2/3" vidicon camera to compare the differences between the 3 tubes. Love to hear comments on it.
