Hitachi Produces 4K Camera For HD Lenses

News Image
Hitachi Kokusai Electric has developed a new broadcast 4K Ultra-HDTV camera system that can adapt 2/3-inch B4 mount lenses used in conventional HD broadcast cameras.

The use of standard HD lenses with the SK-UHD4000 allows broadcasters to use existing lenses and shoot video in 4K resolution, while also retaining the handling and operability of broadcast cameras currently in use.
The SK-UHD4000 is a broadcast 4K Ultra-HDTV camera system equipped with a newly-developed 2/3-inch MOS sensor. This makes it possible to produce video images with high sensitivity and high resolution., while at the same time helping to reduce the amount of power consumed.
The system will be exhibited at the Hitachi Kokusai Electric booth at this year's IBC, Stand 11.D39.
Key features:
• Direct installation of B4 lenses for conventional HD broadcast cameras - The 2/3-inch B4 mount enables broadcasters to directly install their existing lenses. Because the SK-UHD4000 has a 2/3 inch prism, optical characteristics such as depth of field and focus will be the same as a 2/3 inch Broadcast HD camera.
• High quality video in 4K resolution - The newly developed 2/3-inch MOS sensor delivers high sensitivity and resolution. The optical system originally developed by Hitachi Kokusai Electric allows for the reproduction of colour in high-fidelity. Hitachi Kokusai Electric has applied its lens bonding methods and original video signal processing technology to produce high resolution.
• The SK-UHD4000 can output HD and 4K video signals separately, enabling mixing of an HD broadcast camera and the SK-UHD4000 at the same location. This makes it possible to output HD and 4K video at the same time, and to extract HD-quality video from 4K footage.
• Low power consumption - The SK-UHD4000 is equipped with Hitachi’s original technologies for digital video signal processing, optical transmission and high-efficiency power supply. The amount of power consumed by the camera head is suppressed to 38 W, which is equal to the power consumption of a 1080 p HD broadcasting camera.
