Hitachi Introduces 8K Camera With CMOS Sensor

The SK-UHD-8060B incorporates a CMOS sensor with organic photoconductive film to expand dynamic range of 8K acquisition.

According to Hitachi, 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 is claimed to offer 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.

The camera’s Super 35mm OPF CMOS sensor delivers 8K video with 7680x4320 resolution, providing 16 times the picture information of HDTV. It conforms to UHD-2, the ITU-R BT.2020 color specification, ITU-R BT.2100 for High Dynamic Range, and Japan’s ARIB specifications.

There’s support for PL-mount lenses and it 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.

“Hitachi Kokusai has been at the forefront of 8K camera technology for many years, and the SK-UHD8060B continues this tradition of innovation,” said Sean Moran, COO. “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.”
