Abstract (in Japanese) (See Japanese page) 
(in English) Ultra High Definition Television (UHDTV) test broadcasting is planned to start in 2016 in Japan. This will include High Dynamic Range (HDR) television. On the other hand, HDTV with Standard Dynamic Range (SDR) is continued in the existing terrestrial and satellite broadcasting. It would be necessary to produce both HDR and SDR programs simultaneously. In an outdoor shooting environment where the luminance of objects cannot be controlled by producers, HDR and SDR require different iris control. We have devised a television camera that can capture both HDR and SDR images simultaneously. This camera is equipped with “an electronic iris” in addition to a conventional optical iris so that HDR and SDR images can be produced with different aperture adjustments. We have developed a prototype of a camera and confirmed the effectiveness by an experimental shooting.
