Ikegami delivers UHK-430 4K/HD portable camera system
First in Ikegami’s next-generation Unicam XE series, the UHK-430 employs three newly-developed 4K-native ⅔-inch CMOS sensors which provide full 3840x2160 ultra-high definition resolution plus the depth of field required for studio and outdoor production. Equipped with a B4 bayonet mount compatible with ⅔-inch HD lenses, an optional SE-U430 expander can accommodate large studio or OB lenses.
The two piece construction allows the UHK-430’s sensor and lens head to be detached as a compact unit for easy deployment on a support device such as long-reach manually-controlled camera pole. In this mode, the head can be operated up to 50m from the camera body. The head can also be replaced by other assemblies such as a Super 35mm large-sensor front-end. This will be compatible with Positive Lock lenses. Camera heads for special applications will become available as part of the UHK-430 product range, including a high frame-rate version. Additional features include 12G and IP CCU outputs and a new Ikegami processor which allows 40 gigabit/s uncompressed baseband video transmission.
Measuring 149mm wide x 243mm high x 340mm from front-to-back, the 4.5kg model comes with a 2-inch viewfinder and portable lens. An integral B4 bayonet mount allows direct docking with conventional ⅔-inch HD lenses. In addition, a new processor enables the UHK-430 to deliver a wide range of features including a 16-axis colour matrix and focus-assist for 4K and HD video modes. The BT.2020 extended colour space specification is supported in 4K mode, whilst the BT.709 colour space is supported in HD modes and can also be switched in during 4K operation.
Designed for use with the UHK-430, the 3U height CCU-430 camera control unit supports migration from HD to 4K live production. Features of the 18.5kg unit include switchable 4 x 3G-SDI 4K output as well as HD output. An optional plug-in board ensures that 4K video, HD video, and HD cut-out from 4K available can be provided simultaneously. The SE-U430 system expander allows the use of a studio viewfinder and large studio lens with digital interface on Unicam XE series cameras.
An integrated 40 gigabit/s optical transceiver enables full bandwidth 4K resolution signal transmission between the camera and CCU. Uncompressed RGB 4:4:4 signals allow very high quality chroma keying, whilst dual HD outputs cater for teleprompt and talent monitor plus return video lines from studio to viewfinder. The camera also has a Gigabit Ethernet data port to allow networked control.
