A Newly Developed 8K/HLG Broadcasting Camera System With Three CMOS Image Sensors

To date, we have developed various types of 8K cameras while considering the tradeoff between the cost and performance at each period of development. In preparation for both the 4K/8K broadcasting starting in 2018 and the 2020 Olympic Games in Tokyo, we have reconsidered which parameters should be seen as the most important ones for 8K broadcast cameras. We have also reviewed the appropriate elemental technologies for these cameras. In light of the technological advancements that have been made, we decided to develop a three-chip 8K camera with 5/4-in. image sensors. The camera supports both high dynamic ranges and high frame rates; we reduced its size to that of a high-definition television camera. Both its signal-to-noise ratio and sensitivity achieved the best performances of all 8K cameras. This paper discusses both the parameters and the elemental technologies of all of the 8K broadcast cameras that we have examined. <disp-quote xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> In light of the technological advancements that have been made, we decided to develop a three-chip 8K camera with 5/4-in. image sensors. </disp-quote>
