Hitachi Kokusai Electric America (Hitachi Kokusai) just debuted its SK-UHD8060B dockable 8K UHDTV camera. The company’s fifth-generation 8K acquisition solution, the SK-UHD8060B combines the features of previous Hitachi 8K models with a new organic photoconductive CMOS image sensor to capture 8K video with expanded dynamic range.
Existing 8K camera sensors have been limited in their dynamic range and sensitivity by the size of their pixels, which must be much smaller than those of 4K and HD cameras to accommodate 8K’s higher resolution. Using a CMOS image sensor with an organic photoconductive film (OPF) enables a higher saturation charge compared to silicon photodiodes, thus increasing dynamic range without the diminished image quality inherent with previous range expansion technologies. Hitachi claims that the SK-UHD8060B offers greater than 400% dynamic range, maximizing the effectiveness of its support for the Hybrid Log Gamma (HLG) HDR specification and combines it with built-in signal-to-noise management to optimize visual performance. It conforms to global standards including UHD-2, the ITU-R BT.2020 color specification, ITU-R BT.2100 for High Dynamic Range and Japan’s ARIB specifications.
The SK-UHD8060B supports PL-mount lenses and can flexibly output multiple television standards including 8K, 4K/UHD, 1080p, 1080i and 720p. The new camera head can be paired with a dockable recorder that uses a visually lossless codec, avoiding the time-consuming, post-acquisition processing typically required with RAW 8K recording approaches.
Here are the details on the SK-UHD8060B.
