A new UHD 2/3-inch ENG-style broadcast camera has been introduced by Ikegami. The UHK-430 uses three newly developed 2/3-inch 8-megapixel CMOS sensors, offering 3840×2160 resolution plus the depth of field required for studio and OB production.
The sensor and B4-mount lens head can be separated (by up to 50m) for easy deployment on cranes or other remote heads. Peripherals for the UHK-430 will include a high frame-rate head, 4K Super 35mm head, operating control panels, three viewfinders and base stations. An optional SE-U430 expander allows use with large studio or OB lenses.
The UHK-430 has a colour depth of 10 bits per pixel instead of the current eight bits, and uses a new processor, the AXII, reducing power consumption and delivering such features as 16-axis colour correction and new focus-assist for 4K and HD video modes. The AXII also provides the processing for Ikegami’s new i-Log gamma, for a wider dynamic range. The ITU-R BT.2020 extended colour space specification is supported in 4K mode, while BT.709 is supported in both 4K and HD modes.
The companion CCU-430 camera control unit enables easy migration from HD to UHD live production, and includes switchable 4x3G-SDI UHD output as well as HD. An optional plug-in board makes UHD, HD, and HD cutout from UHD available simultaneously. 12G-SDI and video-over-IP interfaces will be introduced soon. A built-in 40Gbps optical transceiver delivers full bandwidth UHD RGB 4:4:4 from camera to CCU, for high quality chroma keying.
