Hitachi Kokusai is manufacturing its 5th generation Super Hi-Vision (8K) camera system with the introduction of its new SKUHD8060B dockable 8K UHDTV camera. The company’s fifth-generation 8K acquisition solution, the SK-UHD8060B combines the rich features and proven advantages of previous Hitachi 8K models with an innovative Organic Photoconductive CMOS image sensor to capture stellar 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. The SK-UHD8060B offers support for the Hybrid Log Gamma (HLG) HDR specification and combines it with built-in signal-to-noise management to optimize visual performance. The SK-UHD8060B’s Super 35mm OPF CMOS sensor delivers 8K video with 7680x4320 resolution, providing 16 times the picture information of HDTV. The new camera 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. The use of a sensor with organic photoconductive thin film enables increased dynamic range not previously possible at 8K resolutions, while its compactness and configuration flexibility make it suitable not only for studio and outside broadcast applications but also for cinematography when combined with an appropriate lens and recorder.

The SK-UHD8000 series is available as a SMPTE Hybrid fiber cable-based production camera system that employs a high performance, multi-format, multi-standard Camera Control Unit.
An 8K recorder can be docked to the camera for field production or used independently. A high-quality 8K visually lossless codec recorder can be ‘docked’ to the camera for untethered field production work.
